Just as a chain is '.'no stronger, than. its weakest .link," each com ponent is carefully designed, selected, and manufactured to;support the over all system. The unit'incorporates quality materials:and equipment with .proven I design features which are the product of over 18.years,experience in' the manu— :facture of air—supported structures. IIThe basic structural element of your system is the strong, .flexible, :shell—type • envelope, which is lightweight, durable,: and fire resistant. %It is constructed of vinyl—coated nylon fabric with a specially formulated coating., which gives good weathering and abrasion resistance. : The envelope:not only provides pro— -, III' tection from the elements, but, when properly pressurized, it also pretensions ' the fabric to;provide maximum resistance to wind -and snow loads. Under normal' operating conditions, the structure will. not be highly loaded and will withstand I considerable lift loads and stresses without adverse effect. ` Rowever, the unit is subjected to maximum design loads, special. precautions should be 'taken to assure the .reliability of the ,structure` and'to prevent'load;concentrations•: which may result in stress of the fabric. Although envelope .design includes a I liberal margin of safety, unusually high loads which may occur during, wind or snow storms can cause damage if the envelope is not .properly:operated, ;maintained, or 'repaired when damaged.. I The;human element 'of operation and maintenance is an equally important link in the chain of reliable performance. Although.operation'is virtually,automatic, ' equipment'is designed for easy'servicing' and`little maintenanceis required: be- 'yond normal :service of operating equipment. This•manual provides basic' instruc— tions. for the installation,' operation, .and maintenance of your structure. iOur experience indicates that' proper ,application of•this'information will .reduce ' problems and assure maximum service life for•the'installation.' In addition, it is recommended that user personnel.should be properly instructed .in the operation. and maintenance of the system to,.prevent misuse.or mishandling. An.effective ' I program of inspection and maintenance should be .established to provide timely.re pairs if the need should arise. , I NOTE: This manual provides adequate instructions for those conditions which are encountered. Itis not practical to'cove usually - r every possible situation which 'may arise. If' you' should have a ,special condition that is not cover ' ed in the manual, please contact the manufacturer: Tensar Structures,.

It is not enough to just buy and use an airstructure. The user,should be I PRECAUTIONS' come involved in the special considerations • for its operation and maintenance.:' Although bad weather is not uncommon, extreme conditions may be serious enough to damage your structure, if special precautions,are not taken to protect the,;. I installation. The user should understand and be alert to these precautions. It is also important to note that proper operation and maintenance by the user. is a major provision of our warranty. • I The Airstructure is a versatile air supported enclosure which offers many ad— vantages not presently available in any other type of structure. No other ', • portable shelter provides the same features, combined with equal strength and I stability. Along with its advantages, the Airstructure also has special char acteristics which should be recognized in its operation and maintenance. It is important to understand and carefully consider these factors so as to fully I benefit from advantages such as low cost, portability, and clear span. For this reason, we emphasize that you should understand and be continually aware of the special limitations and precautions for your structure. Our experience . indi— cates that proper application of these recommendations will assure maximum per- ' formance and service life for your installation. • ••. Your maintenance personnel should be familiar with special precautions and pro— I ,per'procedures to assure the best possible life for your structure. The follow— ing''precautions should be taken for the conditions indicated: • \' GALE WINDS I ' Whenever winds in excess of 50 mph are forecasted, it is essential that your •, , structure be operating properly and at peak efficiency. ':The stability of the unit, and its ability to withstand the forces imposed by high winds, is achieved through pre—tensioning of the fabric by the internal inflation pressure. Air structures are designed to resist severe wind forces up to 70 mph, provided the unit is fully pressurized and securely anchored at the base. In the event of Ihigh winds, the following,items should be checked and corrected if necessary: NOTE: If hurricane force winds (over 73 mph) are predicted far enough in advance, it is recommended that your structure be dismantled and tied down. I I. Operating pressure should be maintained at specified design pressure (approx— imately one inch of water pressure). Maximum pressure should be obtained by ' closing all vents, making sure the seal' skirt (when provided) lies flat, and blocking off all abnormal leakage. • ' I 2. Underhigh winds, personnel traffic and the opening of doors should be limit— ed to avoid excessive air loss.. Doors should not be left open under any con— " Engineering Form No. 13 Pg. 1 of 4 4 II ' 3. High winds 'produce movement of the structure and deflection may be 2 ft. or. more on larger buildings. Materials, lights, or. equipment should not be placed or stored closer than 3 ft. from the inner envelope in order to prevent punc— . I ture or abrasion of the fabric. Particular care should be taken to assure that no sharp corners or objects' can come in contact with the envelope. . • I• ' 4. Remove .any loose debris in the area adjacent to the structure, so as to avoid any chance of it being blown into, or against, the fabric. li' 5. All anchors should be checked and/or adjusted to assure a secure base attach went and the seal skirt (if provided) should be inspected to make sure it:is in poace to minimize the base leakage. I . 6. Select a reliable electrical power source which cannot be accidentally turned off and will not be susceptible 'to frequent power failure. . An emergency power generator with an automatic line. transfer is recommended to ensure reliable I power, particularly if the unit is installed in an extremely exposed location, If a severe storm is forcasted, check that the generator is properly fueled, battery is fully charged and that engine starts easily. I 7. It should be noted that timely maintenance and repair is most important for all elements of the design and cannot be over—emphasized. Your structure should always be kept in. a good state of repair.' Although unit 'design includes a gen— ' erous margin of safety, minor damage may result in a`redistribution of load or . stress concentration, which can cause extensive damage to the . installation under high loads. Continual alertness to potential problems should be practiced by regular inspections (Refer,to check list provided), so' that repairs and adjust ,ments can be made before minor problems become major. It is especially import ant that minor fabric damage be repaired immediately,,because higher than normal ' Sod or snow loads can impose greater stress on the fabric, which could cause ,.extensive damage. ILIFTING OF ANCHORS • IIDue to the variable nature of soil and 'concrete, there may be instances when anchor— age may tend to "creep" or lift under heavily loaded conditions. The following in— • structions are provided to aid you in handling this type of problem: ' 1. Proper drainage of the site is especially important during periods of heavy rain . and melting snow. Wet or swampy ground conditions may affect the load capabil ' ity of anchors. a. Concrete pier, or arrowhead anchors, may be lifted from the ground,if water • is allowed to "seep in" to loosen the anchors. To avoid this problem, the ground surface around each anchor point should be sealed with clay, tar, or I . I ' some other waterproof material to, prevent the entry of water between the anchor and soil. This precaution is particularly, important for arrowhead • : ' anchors. I b. The design load of anchorage depends upon the "holding power" of the ground • • or concrete at each anchor point.' For this reason, it is essential that • the soil around the anchor line should.not be disturbed (i.e.,- installation I of conduit, drain tile, etc.), because this 'will reduce the "holding power" 1111 . of the anchorage. Fill—type soil conditions can also cause similar prob— lems, particularly during wet weather. ' Engineering Form No. 13 - Pg. 2 of 4 g ' 2. Defective anchorage should be immediately adjusted, or repaired, as described in the Operation and Maintenance' Instructions. I CAUTION: It is essential that :repairs be made immediately, because a. faulty ' anchor will transfer 4 of its lift load to each adjacent anchor and can cause a "chain reaction"•anchor failure, which could result in collapse ' of the structure. 3. If an anchor continues to "creep" and cannot be properly adjusted; this is an II - Iindication of poor soil conditions and corrective 'action should be taken.im- mediately. The proper,procedure to prevent more serious damage is to install additional ground anchors, or a different typeof anchor (concrete ballast) I adjacent to the defective anchor. This will allow the new anchorage to carry the load at the "weakened" point to improve the. holding power in the problem area. Install new, ground anchors as described in the Installation Instructions. . DRY SNOW ICAUTION: Snow accumulation should be checked regularly. during periods of heavy snowfall, because timely maintenance is essential to avoid major problems. IDry snow will usually slide or blow off the top of your structure due 'tothe' round- ed design of the envelope. Some snow may tend to accumulate in a ridge on the side away from the wind, but this is not normally a problem because dry snow is lightin I weight. If enough snow accumulates to depress the envelope,' it should be removed using a snow rope. Dry snow may also tend to accumulate on top of your structure when there is a large amount of snowfallunder non-windy conditions. This snow :,should be removed with the snow rope before it accumulates to the extent where it depresses the envelope. IWET SNOW 11e Wet snow conditions can create problems which require prompt attention. . Such snow is quite dense, and if it is allowed to accumulate, the build up can become so great ' that it exceeds the outward pressure of the inflation pressure.' This can cause the. I center section to buckle and collapse the envelope. In addition, the wet snow tends to pack and stick to the structure ratherthan to slide off. ' To prevent this prob- lem, and the 'damage that could occur, wet snow should be removed before it accumu- ' lates to a critical amount. 1. Normally, if the structure is heated, it is important to turn the' inside heat up during heavy snowfall in'order to rapidly melt the snow and prevent excessive Iaccumulation. 2, .If the structure is unheated, or if it snows more than the heat can melt, then I -it is necessary to remove the snow.mechanically.- The recommended method for' re- moving snow is to use a snow rope consisting of a scraper board and rope (see sketch). This board should be smooth on all edges, so that it will not damage .. the' fabric. . Loop one end of the line over the top of the structure, so that it I can be reached on the other side. Lay the board flat on the envelope and pull the board back and forth across the top of the envelope, parallel with the seams, to knock the snow off the envelope. If this is done properly and regularly, ' there should be. no problem due to snow accumulation. Engineering Form No. 13 - Pg. 3 of 4 . CAUTION: Under no circumstances ' . should. doors be 'opened to allow the internal pressure to drop while there is an ' ENVELOPE accumulation of snow on the envelope. This will allow SNOW ROPE a - snow to pocket and make it ' _�-� more difficult to remove. 3. Sometimes heavy wet snow cannot be removed using a snow rope. ''It is 1.x4"X10" then necessary to carefully lean a ladder against the side of the struc— ture trutture and physically remove the snow, ' /. taking special care not to puncture the fabric with the removal tools 4. In the event that snow accumulates faster than it can be removed, it I Snow Removal Using Snow Rope will benecessary to remove (or pad if cannot be removed) any stored material or equipment that has sharp I or pointed corners, so that the depressed-envelope will,not be' damaged if: it is pushed down on these items by the snow. It is not harmful for the snow to depress'., the structure down to rest on stored materials, provided there are no sharp cor— ners, which will damage the fabric. The weight of the snow during removal can al ' so depress the envelope enough to catch on light standards, In the case of tennis ,;. �`ot other recreational structures with lighting,. it is important that light stand— ards be lowered or removed to prevent fabric damage. The envelope can then be • lowered to the floor, the snow shoveled off (again, taking care not to damage the ' '`fabric), and the structure can be reinflated. 1 1 Engineering Form No. 13 —, Pg. 4 of 4 OPERATING INSTRUCTIONS ' An air structure is the ultimate in design efficiency because all material is used at maximum efficiency and no rigid frames or columns are required ' for support. The design concept .provides specials advantages_ such as light ight, portability, .durabi .welity,` and clear span. To achieve these advantages, the•: structure functionsas a dynamic operating system that • I moves freely in a balanced and controlled manner under .load. The unit not -only resists the lift load produced by the internal inflation pressure, but also resists wind forces up to 70 mph. When the system is properly ' operated and maintained, it will provide maximum performance and service to meet your needs. To assure the best possible service and life for your installation, all Ipersonnel who will ,be involved in operation and maintenance activities • should be properly instructed on the unique features of the system. The • fabric envelope, its anchorage, the pressurization system, and all accessory equipment should always be maintained in good serviceable ' condition. This can only be assured by establishing an effective program of regular maintenance and repair under the cognizance, of responsible,' trained personnel . This section provides proper operating instructions for your Airstructure ' system and this information should be made readily available or. posted for user personnel . The following operating conditions should be maintained at al, l .times. t * (a-) Inflation Pressure . Normal operating pressure for your structure should be maintained at I approximately one: 'inch water pressure in order to assure the'stability. of the structure and to avoid excessivedistortion under high winds. If the design inflation pressure is not maintained during high wind • loads, the force of the wind may cause the envelope to buffet and , Idistort inward. This conditionshould be minimized to prevent contact . of the envelope with any material or equipment which may be stored inside, thereby causing damage to the structure. The inflation system for your structure is designed to supply the required inflation pressure if the following operating conditions are maintained. • I 1 . The location and installation,of each blower should be such that ' the airflow to the blower is not restricted. , ' Intake air for the blower should be ambient pressure or above to assure that the ' full pressure differential is maintained. 2. The emergency power equipment with automatic transfer of power to , ; the emergency source-should be maintained in good working order to avoid a' temporary loss of pressure in the event of a power failure. ' Eng. Form No. 39 '- Pg. 1 of 2 • i 1 S , 3. All equipment should be properly maintained so that leakage at the base of the structure and at all doors and openings will be kept at a'minimum. I 4. Accidental damage to the envelope or accessory equipment should be promptly repaired. . ' r C A.0 T I 0 N (b) Clearance for Stored Material or Equipment 1 . Proper clearance .should be maintained between the envelope and any material or equipment stored inside the Airstructure The flexible envelope will deflect under wind loads and the .• . • amount of this deflection will increase with. any loss of I inflation pressure during windy conditions. If a loss of III inflation pressure occurs under high winds, deflectionand billowing of the envelope cancause•it: to abrade or snag on ' ' . ' material inside, thereby resulting in damage to the fabric. 2. 'Maximum distortion will occur onthe windward side of the :, ' ' structure at a height of 15-20 feet above ground level . This inward deflection of the envelope under maximum design ' wind load could be as much as 30 inches. In order to avoid . ' contact with the envelope, any stored material should be placed so as to assure a minimum clearance of at least three feet between the envelope and the..inside contents. ' (c) Avoid Sharp Projections Wherever possible, sharp projections (i .e., vertical pipes or I poles, sharp-edged pallets'or racks, non-collapsible light standards, etc. ) should be carefully avoided (or padded) to prevent these items from coming in contact with the envelope I . This is especially important in the event of emergency conditions such as heavy winds or snows when the envelope may deflect or distort and could be damaged as a result of puncture, abrasion, '. or snagging on any sharp objects. 1 I . 2of 2 Eng.

Verified By ' Date t „ : INSPECTION AND 'MAINTENANCE • The entire. Tensar . ,system should be visually inspected at regular intervals to assure that the installation is maintained in good operating , I condition.:' It is recommendedthat a detailed inspection be made on a monthly basis and whenever a severe storm is forecast until adequate ; y ` experience is gained on the frequency ofservice, required for:';various i • I .components. An Inspection Check List :is. provided as an+aid for inspection and thefollowing major items should be carefully checked to assure reliable, efficient operation of the system ' (a) Check for Secure Anchorage Check that anchorage is secure at all points around the, perimeter:,of I the structure. • Due;to the variable nature `of soil; and concrete, Tenser cannot. assume responsibility, for all anchors' being 100% capable of resistingheav ;: y'lift load conditions. , ` Please be assured that 'most'' I anchors will provide ,this capability or we would not have recommended the anchorageusedfor your installation. We emphasize this factor only to assure maximum reliability for-the: anchorage system. I NOTE: Defective anchorageshould be immediately adjusted,l' repaired, or replaced because"a faulty anchor will transfer 1/2 of its lift load to each adjacent anchor which could cause a "chain • reaction" anchorage failure. In:those instances where the ' soil or concrete causes an anchor: to "creep" or lift up, the following procedure should be' folilowed to correct this conditions • ' 1 . Ground Anchors • To adjust 'a ground anchor, the i'arructure should be softened Y '` to reducethe load on the catenary attachment. This may be accomplished by partially opening a door to, reduce the I internal air pressure;(switch the auxiliary blower to the "OFF" position) . The• door should be operated like a "valve" .by .opening and closing as required to keep the pressure lows .: but not to a point where the structure begins' to collapse. ICAUTION: ' This procedure should only be attempted on a very . • calm day with winds less than 15 mph, because the ' '• unit will be. susceptible' to damage in` this softened •condition. Unhook the catenary cable from the anchor hook. The cable clamps on the anchor cable should be loosened and the slack taken up. ;Pull . ' ' the anchor hook back to ground level: and re-tighten the cable clamps. -• Fasten the'anchor hook back over. • the catenary cable and replace the •special cotter Ipin with the round "eye" toward the structure. • Allow the structure to return to normal pressure andswitch the auxiliary blower to the "AUTO" ' position after inflation pressure returns to one inch. Eng. Form No. 43 - Pg. 1 of 3 S 2. ; Concrete Anchors?. ''' occasionally, an anchor may be located in adefective,or weakened area of,concrete and may•pull._out when subjected I . to heavy. lift loads. In this case the concrete should be chipped away and the old anchors removed. Reset the, anchor with ,"Por-Rok",or. some similar quick-setting high strength concrete compound. ' (b) Check the Inflation Pressure I Pressure must be maintained in thestructure at all 'times .in order to stabilize the envelope so that it can resist the design loading. °'On a weekly basis, check the internal inflation pressure of the structJre as 1 indicated on the pressure gage.or manometer.

DOOR EQUIPMENT Several different types of doors are provided for personnel use. Your installation includes one Model 4B revolving door and one Model 490 ' emergency door. All door equipment is designed to provide simple, re- liable operation with a pressure-balancing feature to minimize the loss of air pressure during entry or exit from the building. 1 . Revolving Door (BDS-1-91 ) I The revolving door is the most efficient method of moving large numbers of people in and out of an air-supported structure. This door places the lightest demand on the pressurization system be- ' cause it is designed to be self-closing against the internal pressure and it conserves the inflation pressure within the' 'structure. The unit is constructed of a coated plywoodenclosure built around a ' molded fiberglass barrel with four solid core aluminum doors which revolve on a bearing-action center post. The revolving door is anchored to a concrete equipment pad which serves as a mounting base ' for the door. After the door equipment is placed and secured to the base pad, use the clamp channels provided to attach the fabric envelope to the door. 1 ' Remove the channels, place the fabric under the channel , and rebolt the channel to the revolving. door. The cables for the door, opening attach to the anchors on each side of the opening with the anchor ' hardware provided. I 2. Emergency Exit (BDS-1-172) The Model 490 exit is a low-cost door which is primarily designed for I emergency use. The door is 42 3/8" widex 79" high and is outward opening with a center pivot action. The door is equipped with panic hardware, a safety glass window, and spring-action hinges which permit the door to close and. latch against ,the internal air pressure. ' This door meets the code and safety requirements foran emergency exit and it is excellent for public assembly applications. t I Engineering. Form No. 98 Page 1 of 6 10/16/79 (rew) 1 II NEXT QTY.

DESCRIPTION: This Birdair designed exit, with its outward-opening door, is a new concept in self-closing emergency exits for air-supported structures. I The door is equipped with a "panic bar" and balance. linkage. ' • This feature, coupled with the use of spring-action hinges, permits the door to close and latch by itself against the pressure in the envelope. As the door opens outward, the linkage moves to the side, providing a clear opening of 39 inches. 1 The door frame is square steel tubing, 'welded construction, and;the door is a flush steel type. The door is braced on the outside and is anchored I . at four points. The. fabric envelope is attached to the frame by means • of fabric clamp strips on the sides and top. • I . A modified version of the emergency exit, for solid wall installation (Sheet 3) , Uses the same door and frame assembly, but without the fabric clamp strips and braces. Instead, a 12 ga. steel-cased opening frame is added to the outside of the regular door frame which allows the 1 complete door assembly to be anchored to any type of wall construction.

Your installation includes a standard fired heating system which is rated at and is specially designed for outdoor installation. The heating equipment is installed externally and is connected to the structure by hot air' discharge and cold I air return ducts. Some units also include provisions for discharging the inflation blower through the heater unit for installations where it is not desirable to have cold air dischargedirectly,into the structure. IThe overall heat transfer coefficient for the single skin envelope material, is approximately 1.2 BTU/hr./°F./sq. ft. The heat transfer coefficient I for areas with a liner (i .e. , two skins, with dead air space) is approximately 0.6 BTU/hr./°F:/sq. ft. However, heating costs can be• minimized by main- taining the structurerelatively airtight to reduce air loss and by controlling ' the regulation of the heaters to heat to higher temperatures only when needed. Since the AIRSHELTER® is a low mass structure, the inside air temperature can be heated quickly and efficiently. ' Your. heating system is recirculating and thermostatically controlled with the following special features: 1. Heavy duty heater unit with stainless steel combustion chamber. ' 2. Heavy duty, quiet blower operation with power draft exhauster. 3. Efficient firing burner with standard electronic controls. ' ,"4." Easily accessible, permanent type,' cleanable filters. 5. Contra] and service panel located on the front of the Unit. ' Operation and Circulation of Heater/Blower Unit(s) The inflation blowers draw external air and discharge it into the heater or ' plenum. At this point it is drawn into the heat exchanger by the heater blowers. It is then heated and discharged into the air structure through the , upper duct on a vertical heater or the left side duct* (view from inside) on a horizontal heater. The remaining duct is an intake duct through which. , ' the circulated internal air and external make-up air are again drawn into.. , the heat exchanger. ' *Note: There are two different arrangements for horizontal heaters. The discharge duct is normally on the LH side for Dravo units and on the RH side for Mammoth units. Air flow is from the cold I air intake to the hot air discharge. IEng. Form No. 42 in Page 1 of 2 Rev. 12 Nov. 1974 (MBP) • • The heater blowers must be operating continually during the winter months ' to achieve the proper flow path. This will also prevent excessive cycle wear on the motor and allows the cool air to absorb warmth from the heat • exchanger, even after the burner is thermostatically shut off. With the ' heater.,blowers .not operating, the external air will flow directly into the structure through the intake duct and maintain the normal operating pressure. Interior temperature should be maintained sufficient to prevent snow or ice accumulation on the envelope. In the case of a lined structure, a single skin "thermal skylight" is frequently used. to increase the heat transfer to the peak areas where snow accumulation would be most critical . Your heating equipment is manufactured by . I and a separate instruction manual_ for. the equipment has been provided by the manufacturer. It is advised that it would be beneficial to become familiar with the typical firing sequence of the heater which is outlined ' in the manual . .

EMERGENCY POWER GENERATOR ' The inflation equipment is the most essential element in your AIRSHELTER°.. system because it supplies and maintains the internal air pressure to support the structure. For this reason, the inflation blowers are designed ' to operate on both commercial line power and on emergency power. An emergency generator provides fail-safe, standby power to operate the in- flation blowers if an electrical power failure should occur. The generator starts automatically, includes batteries and trickle charger, and supplied• continuing power with any loss of normal line power. -' Your installation is designed to operate on a : volt, . phase, hz power source. Themain power is wired to an automatic transfer panel . This panel detects I a power failure, starts the engine generator, and transfers the inflation system over to the emergency power. The transfer panel is specifically sized to match the inflation system. (Any attempt to impose additional electrical. loads may exceed the rated capacity. Any such change must have prior written authorization by .TENSAEL ) When commercial line power is restored, the system will automatically transfer back to the main power . source.'

It can also be usedwith other, ,'controls and systems requiring undervoltage protection. The sensor uses a voltage sensitive relay to monitor the incoming utility II below It will activate the E.G. system when the utility voltage falls below a safe level (80% is standard) , where equipment will over heat and inflation pressures will be reduced. The sensor has built-in adjustable II timers to delay its transfer (transfer to E.G. when utility is unsafe) and re-transfer (re-transfer back to utility when safe) modes. These timers prevent false transfers due to minor line fluctuations. ' Three-phase units also activate under single phasing or phase reversal conditions. LOCATION Install the undervoltage sensor near the load transfer switch to be inter- connected with. . The unit should be protected from direct weather and ' located where its indicators and operating criteria are visible. The location should also prevent unauthorized or accidental tampering with the controls. IIEngineering Form No. 91 Pg. 1 of 4 ' June 78 (CG) 1 -- HOOKUP ' 1 . The required power input is connected to the input fuses at the bottom ofthe panel (refer to HookupDrawing BDS-1-174). Since the sensor has its own internal control transformer, no neutral conductor is required. I 2. The sensor is interconnected to the load transfer switch it controls by two wires. The two wires are connected from terminals No. 6 and 7 Ion the sensor's terminal strip (at the bottom of the sensor's inner panel next to the input fuse blocks) to terminals No. 14 and 15 on the "Remote Test Switch" terminal board in the transfer switch (located on , IIits sub-panel next to the E.G. set mode switch). Remove and discard the factory jumper installed across terminals 14 and 15 before making the hookup. I 3. The enclosure and wiring raceways should be properly grounded. 4.' Phase sequence must be established on three phase units.With.the'sensor's 'I . ' . ON/OFF switch in its "OFF" position; turn on proper' power and allow 10-15 seconds warmup. Observe the, red indicator lamp on the undervoltage relay (UVR). If the indicator is illuminated, the phase sequence to ' the unitis incorrect. Shut off power and swap any two phase connections at the input to the fuse blocks. Turn on and retest. TEST I I . The unit can be tested with or without running the E.G. set. To test• without running the E.G. set, place the E.G. control switch- in the load '. I , transfer switch in its STOP position.- The battery charging ammeter can I ; be used to indicate safe anti unsafe power. When the charge meter shows a charge, it indicates safe power and when it shuts off, it indicates Ithe undervoltage sensor has signaled the E.G. set to start. 2. Place all switches on the sensor in their "UP" position;• place the E.G. I set in its "STOP" position and turn on power. Allow the sensor about two minutes for warmup before testing. 3. Place the "Mode" switch in its test position. In approximately five I seconds the unsafe light will light and the E.G. set will be signaled to start. , I 4.- Move the test switch back to its "Operate"'position. Immediately the unsafe light will go off and the safe light will light. In approxi-. mately 60 seconds a click will be heard and control relay CR2 will I activate (its neon lamp will light in the relay case) and the E.G. set will be signaled to stop. I Engineering Form No. 91 Pg. 2 of 4 ..' - June .78 (CG) 11 5. The re-transfer switch has two positions: in the delayed (UP) position it will delay the re-transfer for 60 seconds before stopping the E.G. II set and returning to utility. In the instant (DOWN) position it will re-transfer immediately without a delay when safe power is sensed. ' 6. The above delay periods are factory settings suitable for most appli- cations. The transferand re-transfer timers are knob adjustable timing relays: 1 Transfer Timer (TD1 ) Adjustable 1-15 seconds Re-transfer Timer (TD2) Adjustable 1-300 seconds ' 7. The undervoltage sensing relay has been factory calibrated and sealed to prevent tampering. Once the seal is broken without written authori- ' zation from Tensar, the system's warranty is void. The undervoltage sensors are calibrated to drop out when utility voltage falls, below 80% of its nominal value, as follows: ' Utility Voltage 208 V Dropout @ 167 _I 240 V @ 192 380 V. @. 304 416 V @ 333 '. 440 V. @ 352 480 V @ 384 i1. n MAINTENANCE Complete visual inspection of the unit, as well as a functional test, should I be made on a monthly basis. The unit can be tested in its test position, or by removing one fuse (with insulated fuse pullers) to simulate a true loss in one phase. 1 TROUBLE SHOOTING ' Procedures listed below assume that proper power is available at the input fuses and .that the transfer panel is operating properly. To check the transfer panel , move its line failure switch to its "OFF" position (mounted above the "Remote Test" terminal board on theinner. panel ). The E.G. set 'I should start; if not, check the overcrank circuit breaker button; if popped out, reset. If it still does not start, problem is in load transfer panel . 1 Engineering Form No. 91 Pg. 3 of 4 ' June 78 (CG) I - 1 , CONTROLS DEAD E.G.

It is through this tubing that the pressure condition is..sensed'by the ' control panel . Care must be taken to protect the tubing from possible damage or kinking. To protect the tubing in exposed s'' areas, install it inside a piece of 1/2's conduit or pipe, etc + ;z:' ` ' - (see sketch #1 ) . If 'the 'location'selected for the control panel is within the pressurized building, change the pressure tap to the low pressure side of the pressure gauge and switch to sense ambient (reference) pressure. 1 i 1 Eng., FormNo. 29 ' Pg. 1 of(pluss a applicable 805's)' r & r , n a 1 , y To install the:pressure tap on the building, select an area ;. , I of double thickness of.fabric at a point",convenient, to-the .';; +., tube run. , Punch 'a 7/16" dia. hole to"'tak'e,the tap fitting '. and complete the assembly as shown..'.;Push the plastic tube ' • onto the tubing adaptor to complete the assembly (see sketch #2) . Minimize excess slack or loops in tubing at areas of , `unequal temperature to prevent, accumulation of condensation. ' _ For pressure tap lines longer than 25 ft. , it is required to, use larger tubing or pipe to maintain ;sufficient volume. ' Refer, to drawing BSP-1-760 for suggested method. OPERATION (I) Set the blower control switches in position for normal . operation: : Main Blower No. ; l "ON" and Auxiliary. Blower ' No. :2 ."AUTO-ON". The building will be maintained at'a positive pressure of approximately 1" H20.with. the main • ,blower in continuous ,operation. ' If;. the. pressure level. falls I . below `.75":'H20, the pressure switch will:,close, activating the low pressure warning light and energizing Blower No. 2 - starter coil through a time delay. This delay;period is about'.10 seconds and serves to preventauxiliary blower I • operation due to instantaneous demands. Note: For cable-reinforced structures the values are: ' + ' 1 .25" H2O and .90" H2O • (2) A pressure rise above .75".H2'O (approximately .85" H2O) ' r will open the pressure switch, deactivating. the warning light and cancelling the auxiliary blower demand. By means of an electronic timer (TD2) , the auxiliary blower will continue to.operate;for an,additional eight minutes. This I . is toprevent rapid motor on and off cycling due to abnormal pressure changes. I Note: For cable-reinforced structures the values are: .90" H2O and 1 .00" H2O. I . (3)` In case of a continued low pressure_condition, the auxiliary blower will continue to operate until pressure rises to a safe level . As before, it will run approximately eight • minutes after safe pressure has resumed. ' (4) A repeated demand requirement of the auxiliary blower is an ' indication of an abnormal condition andits cause should be determined. Possible causes are variable wind conditions, improper door closures, unusual or improper entrance or exit demands, envelope damage or seal leakage,. Corrective action should be taken where necessary. The auxiliary blower may be manually operated at any timeby switching to "MAN-ON" position. ' Eng.

The blower motors are protected by thermal overload relays located on their motor starters in the control, cabinet. , , The overload assemblies are equipped with"automatic/manual, ' resets which are in the automatic position when supplied.:' Single phase units have double overload protection and :three ' phase;units have triple.`overload protection for each motor. I; Overload relays are ambientcompensated to maintain proper trip levels under various ambient temperatures. ' (6) .When two control units are used (on large structures, four, blowers) , it is desirable to adjust'one'' pressure switch' to' actuate slightly below orabove the otherto separate blower starting points. This willlimit auxiliary blower. demands , on a common'pressure drop and stage`?motár starting loads on ' the E.G. system (7) When two control panels are used on' a common generator ; (operating two separate buildings) ,' an extra staging timer is used on the main blower on one panel to;stage starting; • loads of the blowers as above. • 1 . • (8) The external low pressure horn circuit activates with the warning low pressure indicator light. It can be used to r operate any warning device operable on 120volts A.G. ,with `s.. a maximum capacity of 30 watts. (9) The over-ride circuit is used on installations where three inflation blowers are supplied and two are required to main- I tain building pressure. Since one main (continuous) blower (No. 3) is powered by utility poweronly, it is required for both blowers on the control panel to operate continuously on emergency power. The over-ride is activated by an auxiliary contact closure in the E.G.. set's load transfer :t' ' • panel when operating on E.G. power, and places the auxiliary blower in a manual (continuous)operating mode in this condition. Eng. Form No 29 Pg. 3 of 7 I 1 1 ' MAINTENANCE • - Complete visual inspection of the control system and its ' components; should be made at monthly 'intervals. Starters should operate freely and without excess arcing. Contacts should be cleaned or replaced as necessary. The actuation of the pressure switch should be checked either by allow-, ' " • ,ing pressure to drop slowly, or by disconnecting the pressuretap linesandmanually ,increasing and decreasing, , pressure.'

OF THREE BLOWER PRESSURIZATION SYSTEMS (TWO BLOWERS OPERATE ON GENERATOR POWER) The pressurization system consists of three inflation blowers and an • emergency generator shed assembly. The shed assembly contains an emergency generator, load transfer panel , under voltage sensor, and blower control panel for operating two blowers on. utility.or emergency power. I The third blower is connected directly to utility power and does not • operate on emergency power. Under normal power conditions the blower control panel operates Blower I No. i continuously and Blower No. 2 automatically if a low pressure condition occurs. The third blower (No. 3) operates continuously, also from its own main switch. When a low pressure condition occurs, the I control panel will immediately activate its low pressure indicator light and warning horn. If the condition exists for 10 seconds, it will start the auxiliary blower (No. 2). When a safe pressure is restored, the indicator and horn will deactivate immediately and the auxiliary blower I will run an additional eightminutes before automatically shutting off. When normal power fails and the emergency generator operates, the blower I control panel will operate both Blower No. 1 and No. 2 continuously. . •. This is done by an auxiliary contact signal from the transfer panel to r. the control panel. This continuous operation of both blowers is required Ito`provide safe pressure because Blower No. 3 is now inoperable with the `loss of utility power. I A switch is provided at the control panel to test or shut off the warning horn if required while making repairs, etc. 1 . .

For many ' air supported enclosures is a tough, abrasion-resistant material. It is ex- tremely resistant to puncture or tearing. It must be recognized, however, that= accidental damage can be incurred. Sharp,, ' knife-like .objects .will cut`the material. The air-supported structure should be'kept in' a good state of repair to afford maximum security and service life. . Being a highly efficient structural. form, each part of the structure is contributingtothe overall strength. Al I though the maximum loading may only occur. on rare occasions, to assure that the;, structure will resist those conditions when they: are encountered, damaged areas., should always be .,repaired at the earliest possible opportunity.` ;` Repair -General ' A tear or puncture in vinyl coated fabric can be easily repaired with a patch made from the same material. Although a patch canmost easily be applied with the structure deflated, no difficulty will, be experienced in,accomplishing ;. , ' the repair with the. structure inflated The following example is offered to il • - lustrate .the proper procedure. Assumed Damage I `t A .two inch long cut in a panel. With the structure inflated, the load (tension) in the envelope will probably,result inan opening which would.appear.; ' as follows: 111 1 r; OPENING � AREAS OF HIGH STRAIN Engineering Form No. 10 - Pg. 2 of 4 ' Rev.

With the heavier fabric, 1 make holes with an awl to facilitate sewing, and keep an edge distance ofi %" or stag ger, holes to distribute, load.' . ,,. r 1 > , The smoother this sewing is done, the less conspicuous and more sound will be the ' I final repair. The sewing is not expected to develop the full strength of the mater- ial, but to position the material for properpatching and to support normal loading until the cemented patch has fully cured. In' sewing on an inflated structure, it „ will be found advantageous to'lower.the pressure by partially opening the door. This 1 should, of course, only be done under low wind conditions. 1 Make_Patch' The size of the patch will be a function of;the"size and shape ofthe tear 1 or cut. The size of the patch should be such that the patching:material extends a minimum distance equivalent to the joint width used on.the particular structure in all directions from the damage. The orientation of the weave of the patch material : 1 .' : should correspond to the area patched.

' Thoroughly clean all bonding surfaces to dullness with a clean: cloth dampened . with Methyl Ethyl Ketone solvent. Do not saturate rag with MER, as excessive ' solvent may lift vinyl coating from fabric. This is especially critical if • the base material has a laminate coating. Repeat solvent' cleaning process where necessary. Allow the solvent-washed areas to dry prior to adhesion ap- plication. ' APPLICATION PROCEDURES: VB-71331 is primarily designed for solvent activated assembly using Tetrahydrofuran (THF) as the activating solvent. ' SOLVENT ACTIVATED ASSEMBLY: Brush apply two light coats of VB-71331 to each bonding surface, allowing a minimum 15 minutes drying time, or dry to touch, between coats and for drying of the second coat. Prior to assembly, brush I or swab apply THE over both bonding surfaces, position, and assemble within 20 seconds under firm hand rolled application. Do notattempt to reactivate 6-8" at a time. If a large patch is required, it should be reactivated in ' steps. After patch is applied, apply firm pressure with knotted rag or roller to insure intimate contact between patch and structure. This method of ap- plication requires an extensive length oftime to cure at room temperature. * NOTE:. In some cases, the exterior surfaces of the airstructure have been treated with a gloss urethane top coating. This coating must be I removed from the surface by means of light sanding with a fine grade sandpaper before attempting repairs, as described above. As an alternative, the patch may be bonded to the inside surface. DO NOT use this adhesive on liners or lightweight scrim laminate • fabrics. The solvents involved may cause blistering and delamination. 1 1 ' Eng. Form No. 54 • IIRev. 1 of 1 Rev. May 81 (KR) Rev. Feb. 83 (DS) 1 • CEMENTING PROCEDURES ' A-254 Adhesive For Liner Fabric ' General Information The A-254 adhesive can be used for structural and non—structural;bonding of light Iweight fabrics, such as.N1VF6 STYLE-4802, N3VF2O. Because the coatings on these fabrics are susceptible to solvents, extreme care must be exercised during the ap- Iplication of the adhesive and the associated solvents, to avoid "bubbling" and lifting of the fabric's coating. Application Notes ' 1. These fabrics can be cleaned only with toluol. The cloth should only be damp— ened, NOT SATURATED. During the cleaning, turn the cloth frequently, so the ' dirt is picked up, rather than spread around. Avoid Spills. 2. Apply the adhesive in thin, even coats. Excessive amounts will "bubble" or ' lift the fabric coating. 3. Avoid prolonged brushing. The adhesive dries quickly, and excessive brushing ' will create a rugged application. ' Step, # :l Clean the surfaces to be bonded together with toluol. The cloth should only be dampened and turned frequently to pick up the dirt. Step # 2 ' Apply a coat of the adhesive to both surfaces. The adhesive should be applied thinly and evenly. Do not over—brush. Allow this coat to dry completely I (5 to 15 minutes, depending on conditions). I Step 11 3 Apply a second coat of the adhesive in the same manner as the previous coat. (Step # 2). Allow to dry. Step # 4 IDampen, DO NOT SATURATE, a cloth with T.H.F. solvent. Lightly wipe both sur— faces with the cloth to reactivate the adhesive. Wipe only 12. inch areas, as 1 Eng. Form No. 54—A I Pg. 1 of 2 RFB — 78 CEMENTING PROCEDURES — A-254 Adhesive Cont'd.I 1 the tack time is very brief. Join the two surfaces together and roll or plate to gain full contact. Step # 5 I Allow the joint to cure 15 to 30 minutes. CAUTION — Because the adhesive and solvents have a tendency to soften the coat— , ing, premature pulling of the joint will result in a coating separation until it is' cured. • 1 t r,•y` Eng.
