START THE PUMP

PREPARING TO START 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.
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.
