Preparing to Start the Pump – Deep Well 11
Never run pump dry. Running pump with-
out 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
15). 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 16).
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 pres-
sure. 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 pip-
ing. 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 17) 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 17). 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 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.
If you were unsuccessful, please refer to the
Troubleshooting section (Page 13) or call our customer
service technical staff.
