Installing the Compressor

2.1 Identifying the Best Mounting Position

Using the following points as guideline, identify a position on the vehicle or inside the
cabin where the compressor can be safely and conveniently mounted.
NOTE : The ideal position of the compressor should give consideration to all of the
following points:
1. The location should allow for quick and easy access to the compressor for attaching an
optional pump-up kit air hose for tire re-filling if desired.
2. Keep away from sources of heat (e.g., too close to exhaust system components or
directly behind the radiator, etc.).
3. The position should be safe from damage or abrasion caused by sand or gravel from
the road surface.
4. Avoid any extended exposure to direct sunlight.
5. Keep away from excessive moisture (e.g., directly exposed to road spray or rain runoff).
6. Mounting location should be above the highest possible waterline to avoid submerging
during water crossings.
7. The position must allow free flow of dry, cool air to the air filter assembly (unless an
intake extension tube is to be used, in which case it is the filter assembly and the
extension tube which must be located accordingly).
8. The position should allow access to the air filter assembly for filter disassembly and
cleaning (unless an intake extension tube is to be used).
9. If an intake extension tube is to be used then consideration should be given to the
intake position so that the distance (length of tube) between the compressor mounting
location and the actual air intake point can be kept to a minimum.
10. The position must allow the compressor motor mounting bracket to firmly secure the
compressor using all 4 bolts.
11. The position must allow access to the opposite side of the mounting location so that the
backing plate and locking nuts may be installed.
12. Parts of the compressor may get hot while running for long periods of time, and
therefore the compressor should be located away from where it could be touched by
children or pets.
13. The position should permit a short (close to the battery), protected and accessible route
for the wiring loom to follow.
LONGER POWER WIRES = MORE INLINE RESISTANCE = LESS AIR FLOW RATE
14. The compressor should not be mounted in a position where the running sound might be
considered startling or irritating for vehicle occupants.
15. The compressor should not be mounted in close proximity to devices that are sensitive
to the electromagnetic fields of DC motors (e.g., compasses, radio/GPS antennas,
engine management sensors, etc.).
16. Where possible, the compressor should be mounted close to the location of the Air
Locker equipped axle in a single Air Locker system, or halfway between both axles in a
dual Air Locker system.
17. Never mount the compressor in a position where it would be considered unsprung
mass (e.g., mounted directly to the axle or the engine block).
