Preparing to Start the Pump – Deep Well
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.
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.
Step 1. Open the control valve as far as possible (see
Figure 10). 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 prim-
ing tee in the suction piping, remove the plug from
the tee and fill the suction piping.

Step 3. Power on! Start the pump and watch the pressure
gauge. The pressure should build rapidly to 50
PSI as the pump primes.
Open control valve
as far as possible
and fill pump and
piping through
priming tee.

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 forget 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. When the
needle flutters, close the valve just enough to
stop the flutter (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 run-
ning 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.
NOTICE: Packer jets (2" and 3" single pipe wells) do not
form a perfect seal. Normal irregularities in the cup seal
leather and the inner walls of the casing will allow the
pressure in a dormant system to leak off over time. This
will cause the pump to cycle periodically to maintain the
system pressure level.
