it's set to 18 psi.
a. Use a tire pump to adjust the
psi to 18 psi
Vent plug
b. If water leaks from the air
release valve, replace the
pressure tank.

CAUTION: Make certain that the power
source matches the pump requirements. Pump
has a dual voltage motor and can run on either
115 V or 230 V.
Pump is pre-set at the factory to run
on 230 V.
To change pump voltage, remove the square
voltage switch cover at the top of pump and
move the voltage switch as shown.

Setting
CAUTION: All pumps must be primed by filling the cavity with water before they are first operated. This will take several gallons of
water, as the suction line must be filled in addition to the cavity of pump. Depending on the length of suction pipe, many gallons may be
needed to fill the entire system.

of pump stays constant. If water level
goes down, it could indicate a leak in
the foot valve, check valve or suction

vent plug threads with thread tape and
thread into pump. Tighten with wrench
(not included).
