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 to 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 selection switch is located inside the terminal box.
The motor is factory wired on 115V. For 230V selection, please open the terminal cover and set the switch to
the proper voltage. (See above drawing on right ).
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 have to be done carefully.
Turn adjustment nut half 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.
