Preparing to Start the Pump

PREPARING TO START THE PUMP
Figure 10: Prime the Pump
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.
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.
Fill pump
and piping
through
priming tee.
Can fill downpipe
separately through
2nd priming tee.

1. Remove the priming plug from the priming tee 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. See Figure 10.
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 15 minutes 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.
Congratulations on a sucessful installation.
If you were unsuccessful, please refer to the
Troubleshooting section (Page 12).
