water may cause pump to overheat, damaging seal and possibly

NEVER RUN PUMP AGAINST CLOSED DISCHARGE.
do so can boil water inside pump, causing hazardous pressure in
unit, risk of explosion and possibly scalding persons
handling pump.
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.
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.
5. 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.
