Operation
PREPARING TO START THE PUMP –
DEEP WELL
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. Open the control valve as far as
possible (See Figure 17). 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 18).
3. Power ON! Start the pump and
watch the pressure gauge. The
pressure should build rapidly to 50
psi as the pump primes.
4. 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 pressure has built up and
stabilized at about 50 psi, slowly
open the control valve (See Figure
19) and let the pressure drop until
the pressure gauge needle starts to
flutter. When the needle flutters,
close the valve just enough to stop
the flutter (See Figure 19). Your
pump is now operating at its most
efficient point.
6. 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
