Preparing to Start the Pump – Deep Well
9
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.
Step 1. Open the pressure regulator as far as possible without backing it
out of the regulator body. Then remove the regulator 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 (see Figure 10).
Step 2. Replace all fill plugs and close the control valve completely
(Figure 11).
Step 3. Power on! Start the pump and watch the pressure gauge. The
pressure should build rapidly to about 50 PSI as the pump primes.
Step 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 for-
get to close the control valve each time before you start the pump.
Step 5. When pressure has built up and stabilized at about 50 PSI, slowly
open the control valve (see Figure 12) and let the pressure drop
until the pressure gauge needle starts to flutter or drops to 0. When
the needle flutters or drops, close the valve just enough to stop the
flutter or bring the needle back to a stable pressure (see Figure 12).
Your pump is now operating at its most efficient point.
Step 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 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.
