Preparing to Start the Pump
Fill pump and piping through 
priming tee.
Can fill downpipe separately through 2nd priming tee.
Figure 6: Prime the Pump
Priming
Explosion hazard.. 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.
Burn Hazard.. 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 (Figure 6). 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
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.
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.
