Owners manual

select compressor’s mounting location where air line can be routed from compressor
air inlet to remote inlet air filter. Make sure that the remote inlet air filter is located in
a dry location, away from water. You will also want to select a compressor mounting
location where the leader hose bracket can be mounted to secure the 2 ft. leader hose.
• If it is necessary to mount the air compressor further from the battery, such as inside
your vehicle or in the bed of your pickup, use a minimum 10 AWG positive lead wire
for remote installation.
• Do not mount compressor near areas where flammable liquids are stored.
Compressor Installation, Mounting and Wiring:
1. Disconnect ground cable from vehicle’s battery.
2. Temporarily position the air compressor 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 the air compressor with the four sets of 13/64” (5 mm) bolts, nuts, washers,
and locking washers provided. Use of thread locker is recommended.
5. NOTE: For Remote Inlet Air Filter Installation, refer to Remote Inlet Air Filter
Installation Instruction included in the Remote Inlet Air Filter Pack.
6. This air compressor comes with a heavy duty heat resistant stainless steel braided
leader hose with ¼” fittings. This leader hose is designed to prolong the life of your
air line. Do not remove this leader hose from air compressor.
7. IMPORTANT: Please note; the leader hose that came with your compressor has a
built-in inline check valve. Do not remove inline check valve from leader hose.
8. Select a proper location to mount leader hose with hose bracket provided. Avoid
locations where leader hose may become tangled with wires and other hoses.
9. To mount hose bracket, drill holes with 3/16” drill bit and push self–anchoring hose
bracket pin into hole. Route leader hose through hose bracket and secure hose by
pressing bracket clamp into locked position.
10. To remove hose from the hose bracket, simply press down on the hose clamp release
tab to release bracket clamp.
11. Use a relay to supply power to the compressor. The Kleinn 6850 Installation Kit has
all the required connectors, and includes a color coded wiring diagram. If you do
not have a 6850 wiring kit, connect the relay as follows:
• Pin 30 – to red wire on the compressor
• Pin 85 – to one side of the pressure switch
• Pin 86 – to ground
• Pin 87 – to battery/fuse
• Connect the other terminal on the pressure switch to a switched +12v power
source. (Switched = turns on/off with the car’s ignition)
12. Make sure that your compressor setup is properly fused. The compressor pulls
approximately 14 maximum amps of power.
13. Always locate fuse as close as possible to power source.
14. Before connecting to power source, check to make sure that all connections are made
properly.
15. Connect and test compressor system by running the compressor for a short time to
build up pressure in your air tank.
