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, 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 adjusted 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 adjustment nut 1 a half turn at a time. (Do not adjust nut 2).
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.
