Step 1. Open the control valve as far as possible (see Figure 9). 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 10).
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 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 11) 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
11). 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.
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.
