PREPARING TO START THE PUMP – DEEP WELL
PREPARING TO START THE PUMP
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.
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.

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 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 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.

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.
NOTE: 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.
