ELECTRICAL INSTALLATION
STEP 9

We recommend that a licensed electrician be employed to do the proper wiring to the pressure switch,
and to permanently ground the motor in accordance with the electrical codes in your area.
Do not use an extension cord to connect your pump to the power source. From your
distribution panel to the pressure switch, we recommend a wire gauge not smaller than 14 gauge.
This is a dual voltage 115/230 pump. The voltage selector switch is located inside the terminal box on the
motor. The motor is factory wired at 115V. For 230V selection, please open the terminal cover and set the
switch to the proper voltage. (See above drawing on right ).
The pressure switch setting (start/stop 20/40 or 30/50) has been made at the factory. Adjustments may be
done to give other operating pressures.
Adjustment or modification of start/stop setting of pressure switch has to be done carefully.
Turn the adjustment nut half a turn at a time.
Turn nut 1 clockwise to raise start and stop pressure setting.
Never turn nut 2. This will change the 20 PSI
range between start and stop pressure and may damage your tank’s bladder or modify the efficiency
of your water system.
Check system operation after each adjustment.
