PVC pipe needed to connect the PVC adapter in the

discharge tee to the male adapter on the tank tee
inlet. Set pressure in the diaphragm pressure tank to
2 pounds less than the cut-in pressure of the pump.
The cut-in pressure of these pumps is factory preset
to 18 PSI. If this cut-in setting has not been changed,
then the diaphragm pressure tank should be set to 18
PSI. Total installation should look like drawing at right.
Open a faucet or two in

the house. Start motor.

Turn regulator adjustment
screw down tight. If pump
is properly primed, a high
pressure will immediately
show on the pressure
gauge. With pump
operating at high pressure,
slowly unscrew regulator
stem until maximum water
flow is obtained without
dropping to zero. If no pressure shows, stop motor,
remove pressure regulator from pump, add more
water, and try again.
WARNING Risk of explosion. If you change pressure switch settings, set the cut-off pressure
low enough to shut off the pump. If the valve shuts off and the cut-off setting is too high,
the pump will run continuously without water flow, causing overheaating
and possible explosion which can cause serious burns and damage.
DRAINING FOR SERVICING OR FOR WINTER
The pump should be drained before it is disconnected for
servicing or if it is in danger of freezing. To drain:
• Remove drain plug from bottom of pump case.
• Remove discharge tee to vent the pump.
• Drain all piping to a point 3 feet (1 meter) below
ground level.
For wells 25 feet or less in depth, the 1/2 HP, 3/4 HP and 1 HP
pumps are recommended. However, the 3/4 HP and 1/2 HP
convertible pumps may be adapted to shallow wells with
ejector kit.
