CONTROL NOTES:

THE PUMPING STATION WILL BE SET UP FOR THE FOLLOWING

OPERATION. THE UNIT SHALL HAVE FLOATING BULB SWITCHES FOR

PUMP CONTROLS. AS THE WATER RISES & SWITCH # 2 IS

ACTIVATED, PUMP #1 SHALL COME ON. AS THE WATER CONTINUES

TO RISE & SWITCH # 3 IS ACTIVATED, PUMP #2 SHALL COME ON.

THE TWO PUMP SHALL CONTINUE TO RUN UNTIL SWITCH #1 IS

BROKEN AND BOTH PUMPS SHALL CYCLE OFF. THE CONTROLS

WILL HAVE A SHORT CYCLE TIMER THAT PREVENTS SHORT

CYCLING OF THE PUMPS. THE PUMPS SHALL HAVE ADJUSTABLE ON

AND OFF TIMERS.
