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.
Risk of explosion and scalding . 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. Open the control valve as far as possible (see Figure 18). Then 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 and close the control valve completely (Figure 19).
3. Power on! Start the pump and watch the pressure gauge. The pressure
should build rapidly to 50 PSI as the pump primes.
4. Open several faucets in the residence to permit water flow and to
release trapped air. After 2 or 3 minutes, the gauge should show
pressure. If not, stop the pump, remove the fill plugs, reopen the control
valve, and refill the pump and piping. You may have to repeat this two
or three times in order to get all the trapped air out of the piping. Don't
forget to close the control valve each time before you start the pump.
5. When water pressure has built up and is maintained by the pump,
slowly open the control valve (see Figure 20) while watching the
pressure gauge needle. Continue opening the valve until the valve is
fully open or you see the pressure gauge needle start to flutter. If the
needle starts to flutter, slowly close the valve just enough to stop the
flutter. Your pump is now operating at peak efficiency.
6. Close all open faucets. 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 successful installation.
