Priming
Risk of explosion. Do not ground to a gas supply line. Never
run pump against closed discharge. To do so can boil water inside pump,
causing hazardous pressure in unit, risk of explosion and possibly scalding
persons handling pump.
Risk of burns. Never run pump dry. Running pump without
water may cause pump to overheat, damaging seal and possibly causing
burns to persons handling pump. Fill pump with water before starting.
1. Remove the priming plug from the pump and fill the pump, fill all
piping between the pump and the well, and make sure that all piping
in the well is full. If you have also installed a priming tee in the suction
piping, remove the plug from the tee and fill the suction piping.
2. Replace all fill plugs.
3. Power on! Start the pump. If you don’t have water after 2 or 3 minutes,
stop the pump and remove the fill plugs. Refill the pump and piping.
You may have to repeat this several times in order to get all the trapped
air out of the piping. A pump lifting water 25’ may take as long as
15minutes to prime.
4. After the pump has built up pressure in the system and shut off, check
the pressure switch operation by opening a faucet or two and running
enough water out to bleed off pressure until the pump starts. The pump
should start when pressure drops to 30 PSI and stop when pressure
reaches 50 PSI. Run the pump through one or two complete cycles to
verify correct operation. This will also help clean the system of dirt and
scale dislodged during installation.
Winterizing the Pump
To prepare the pump for freezing temperatures:
1. Shut off power to the pump.
2. Relieve system pressure. Open a faucet and let it drain until water
stops flowing.
3. Drain the pump. Your pump may have a separate drain plug. Remove
this plug and let it drain.
Your pump may only have a plug or connection on the side of the
pump. Remove this and let the pump drain. Some water will remain in
the pump. A small amount of water left in the pump will not harm it if
it freezes.
