WIRING COMPRESSOR (Fig . F)
15. The compressor’s red wire is connected to (+) 12-volt power source using
the fuse provided. IMPORTANT! The red wire must be connected to a (+)
12-volt power source only when the vehicle ignition is turned on. This will
protect your compressor from running continuously and being damaged if an
air leak develops when the vehicle is not in operation. Suggested connection
points are: blower motor, windshield wiper motor or accessory terminal on the
fuse panel. Make sure the connection point has a wire that is as heavy as the
compressor wire.
OPTIONAL: A switch can be installed into the compressor’s red wire. This
will permit the driver to turn-off the system if it is not required.
16. Remove the plastic cap covering the pressure switch. The compressor’s
black wire is connected to one of the terminals of the pressure switch on air
tank.
17. Connect the short black length of wire provided to the other terminal of the
pressure switch.
18. The other end of the black wire is connected to ground; secure the wire’s
terminal to either the (-) side of vehicle’s battery or under any metal body
bolt. Make sure that ground connection is free of rust and paint.
NOTE: The compressor is now ready to be used and will automatically start
when the pressure drops in the tank. The built-in regulator will automatically turn
off the compressor when the tank pressure is approximately 110 p.s.i. If the
compressor does not shut off after 4 minutes of running time, check all air hose
connections for leaks. Use soapy water or bubble solution on each fitting while
the compressor is pumping. Use a thread sealant if leak persists after
tightening.
CAUTION: Do not touch compressor or fittings with bare hands during or
immediately after usage, they will be hot.
IMPORTANT! Compressor is equipped with THERMAL OVERLOAD
PROTECTOR. If unit should shut off automatically during operation, do not
attempt to restart compressor. Allow compressor to cool off for approximately 40
minutes before resuming use.
