ELECTRICAL INSTALLATION

STEP 9
We recommend that a licensed electrician be employed to do wiring to the pressure switch.
Permanently ground the motor in accordance to the electrical codes for your area.
Do not use an extension cord to connect your pump to the power source. From your distribution
panel to the pressure switch, install a wire gauge not smaller than 14 gauge. See the wire
chart below for wire length above 100’.
Pressure switch setting (start/stop 20/40 or
30/50) has been made in factory. An adjustment
may be done to give other operating pressures.
The pressure switch setting was done at the
factory (start/stop 20/40 or 30/50). Adjustment
or modification of start/stop setting of
pressure switch have to be done carefully.
Turn adjustment nut 1 half turn at the 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.
