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 12). 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.
Step 2. Replace all fill plugs and close the control valve
completely (Figure 13).
Step 3. Power on! Start the pump and watch the pressure
gauge. The pressure should build rapidly to 50
PSI as the pump primes.
Step 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
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 14) 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 14). Your pump is now
operating at its most efficient point.
Step 6. After the pump has built up pressure in the sys-
tem and shut off, check the pressure switch oper-
ation by opening a faucet or two and running
enough water out to bleed off pressure until the
pump starts. The pump should start when pres-
sure 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.
