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. 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.
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 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.
