150 PSI HIGH-FLOW AIR SOURCE KIT
USER MANUAL
MOUNTING AND WIRING:
1. Disconnect ground cable from vehicle’s battery.
2. Temporarily position the air source kit in the location
where it will be mounted.
3. Route ground wire to the negative post of the battery or to
an appropriate grounding point and cut ground wire to
length as needed.
4. Mount air source kit at tank leg mounts with the four
grommets, and four sets of bolts, nuts, washers,
and locking washers provided. Use of thread sealant
is recommended.
5. Route 3/8-inch I.D. air line from the 1/2-inch tank port
to a 3/8-inch compression fitting and make your air line
connection. Tighten compression fitting nut securely
using a wrench.
6. Connect ground (Black) wire to a clean ground, (preferably a
chassis ground) and secure with a self-tapping screw.
7. Connect positive (Red) lead wire from pre-installed
pressure switch to a fuse holder (25-amp minimum).
8. Once the kit is properly fused as close as possible to
the power source, connect and test compressor system
by running the compressor for a short time to build up
pressure in your air tank.
9. Once air pressure reaches preset cut out pressure of
your pressure switch (100 PSI cut-on, 145 PSI cut-off), the
compressor will shut off automatically. Inspect all air line
connections for leaks with soap and water solution. If a leak
is detected, the air line may not be cut squarely or pushed
all the way in. Tighten connections if needed.
