1) Submersible Pump -Meyer Co.: SRM -4
2) 2" Force Main to drain back into pump chamber
at the end of each pumping cycle.
Use 5/16" Drain Hole following 2" Check Valve.
3) Alarm Panel - SJE Rhombus Tank Alert -1
4) Alarm is to be on a separate circuit from pump.
5) Pump Sequence:
a) Pump off EI. 43.85 (1.5'OFF Tank Btm.)
b) Pump on EI. 44.35 (2'OFF Tank Btm.)
c) Alarm on EI. 44.85 (2.5'OFF Tank Btm.)
6) Quick Diconnect Fitting to be installed
on horizontal Fine of force main for
use when servicing or removing pump.
*Disconnect must be accessible from
