INDEPENDENT COMPRESSOR / TANK MOUNTING
(Fig. 1):

independent of the tank, remove the four screws that
secure the compressor to the tank, then disconnect
the braided hose from the tank. You will now be able
to separate the compressor from the tank.
COMPRESSOR and TANK INSTALLATION (Fig. 2):
IMPORTANT! When selecting a mounting location for
the compressor, make sure that the compressor’s
braided hose will be close enough to the tank’s inlet
connection.
COMPRESSOR INSTALLATION (Fig. 2A):
2. Locate a convenient location to mount the
compressor that will be dry. If the location
is the engine compartment make sure
the compressor is safe from the heat of
the exhaust manifold and try to mount
compressor as far to the front of vehicle as
possible to provide optimum airow around
compressor. IMPORTANT! Do not mount
on a plastic fender well, or on exible
material.
3. Using the compressor’s mounting base as
a template, mark the hole locations and
drill to size, use a 3/16” drill bit. Secure the
compressor to the mounting surface using
the hardware provided. (Fig. 2A)
TANK INSTALLATION (Fig. 2B):
4. The mounting location for the tank should
be easily reachable so that the tank
can be periodically serviced, draining
condensation, water from the petcock
located on the bottom of the tank.
5. Use the tank’s mounting bracket as a
template, mark the hole locations and drill
to size 15/64”. Secure tank with hardware
