PLUMBING THE AIR COMPRESSOR
1 Once the air compressor mounting location has been chosen
and the mounting holes are drilled, the manifold can be installed.
The air manifold assembly is mounted to the top of the two
mounting feet on the discharge side for vertical head and the
opposite side of the head for horizontal head models. The air
manifold provided contains a pressure switch, unloader valve,
one way check valve, one air inlet port and two air outlet ports.

the manifold to the compressor. One outlet port is the air supply
to the tank and the other port can be used to supply air to an
accessory, a gauge or be plugged off for future use (a ¼” NPT
 plugisprovided).UsethreadsealantorTeontapeonallttings
installed to prevent air leaks.
3 Usingthettingsprovided,connectthecopperdischargelinefrom
the compressor head to the manifold inlet port. The length of
copper line is designed for the horizontal compressor head.
Vertical head installations will require this line to be cut before the
bend with a tubing cutter.
Thank you and congratulations on the purchase of a Pacbrake air compressor with unloader installation kit. This kit
contains the basic electrical system and plumbing components needed to operate the air compressor.
Please read these instructions carefully to ensure you can complete the installation once started.
NOTE:Thiskitincludes“pushtoconnect”airlinettings.Theyrequiretheendoftheairlinetoberound,squareand
cleanly cut to ensure the internal seal will not leak air. The airline must only be cut with a sharp razor knife. Using
scissors, a hose cutter, or wire cutters will distort the airline causing the connection to leak air past the o-ring seal.

TESTING THE SYSTEM
To ensure correct air compressor operation, a long trouble free life and customer satisfaction, it is recommended the
“cutin”and“cutout”pressuresbeveried.
If a permanent air pressure gauge is not being installed, temporarily install one into the air tank or manifold’s outlet
porttoverifythesystemoperatingpressureiswithspecications.
Ensure the air compressor ON/OFF switch is OFF, then rotate the vehicles ignition switch to ON. (It is advisable
to have the vehicle running while performing this test if multiple cycles of the compressor is performed). Turn the
compressor ON/OFF switch to ON, the light in the end of the compressor ON/OFF switch should illuminate and the
compressor should start to pump air. Watch the air pressure gauge as the compressor must turn off before 145
PSI is achieved. Then activate the accessory to reduce the air system pressure until the air compressor “cuts in”
this should be no less the 95 PSI. The air compressor “cut in” and “cut out” pressures are a function of the pressure
switch, if the “cut in” and “cut out” pressures are not suitable for the accessory being operated a different pressure
switchisrequired.Atthispointitisadvisabletosoaptestallthettingsforairleaks,correctallairleaksastheywill
cause the compressor to cycle more often . If the compressor does not perform as above, check all the wiring con-
nections, power sources, fuse, circuit breaker and grounds to ensure good connections have been made.
