1 4. T his pump is pre-wired at 230 volts. If the power
source is 115 volts, remove the electrical housing
cover. Flip the switch to 115 volts. Replace the cover.
N OTE: All electrical work should be performed by a
licensed electrician.
PRESSURE SWITCH INSTALLATION INSTRUCTIONS
WARNING! Before wiring the pressure switch, turn off the power source to which you are connecting to
avoid potentially life threatening electrical shock.
WARNING! It is recommended all electrical work be performed by a licensed electrician.
WARNING! When wiring from the power source to the pressure switch, it is recommended that you use
either a 14-gauge or 12-gauge cord.
T o complete the installation, you must connect the power source to the pressure switch. A 30/50 PSI
pressure switch has been installed on the pump. The pressure switch allows for automatic operation;
the pump starts when pressure drops to the "cut-in" setting (30 PSI pre-set).
1 . T o wire the pressure switch:
R emove the pressure switch cover on
pump to expose the wiring terminals.
C onnect the green ground wire of the power
supply to the switch ground terminal.
C onnect the power supply wires to the two
outside terminals marked "LINE" and replace
the switch cover.
I f you had a different pressure switch on the old pump (ex. 20/40 PSI), make sure to adjust the
pressure in your tank to 28 PSI! You may need an air compressor to add air pressure. If you
have too much air pressure in the tank, simply press the air stem down to release air.
Y ou will need a tire gauge to test the pressure in the tank!
