Preparing to Start the Pump – Deep Well 11
For parts or assistance, call Flotec Customer Service at 800-365-6832
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 peakefficiency.
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.
