NOTE ON CONNECTING AIR LINE TUBING

Cut the air line tubing as squarely as possible. To connect the air line tubing to the fittings push the tubing into the fittings as far as possible. If for any reason the tubing must be removed the collar of the fitting can be pushed toward the body of the fitting and the tubing can be removed. Make sure the air helper springs are deflated. To reassemble make sure the tubing is cut squarely and push back into the fitting.

STEP 1

Locate the brass "T" fittings as shown in Figure "A". This fitting has a preapplied thread sealant on the male threads. No additional sealant is required.

Install the male threaded end into the compressor head as shown in Figure "A". Tighten finger tight PLUS 3 1/2 turns. Next get the pressure switch from your hardware pack. Screw the pressure switch into the "T" fitting as shown in Figure "A". Then attach the positive (RED) wire from the compressor to one of the terminals on the pressure switch. Install the rubber isolators and brass sleeves to the compressor feet (see Figure "B").

STEP 2

Select a convenient location for mounting the compressor. This location should provide ample air flow and be protected from most airborne debris. The surface should be rigid to support the unit. Some examples might include under the hood on a fender well, or in a vented storage compartment.

Using the template supplied, mark and drill three 1/4" holes. It is recommended that burrs be removed from the holes so as not to damage the rubber isolator. Mount the compressor using the #10 pan head

machine screws and #10 flat washers located in your hardware pack.

Assembly of the flat washers, machine screws, and lock nut are shown

in Figure "B". Proper mounting of this compressor will provide

maximum isolation. Figure "B" shows the before and after condition

of the rubber isolator. The screw and nut should be tightened only

enough to bottom out on the brass insert. DO NOT OVER TIGHTEN

further tightening will crush the insert and isolator and reduce vibration

isolation.

Attach the black wire from the compressor to a convenient ground source on the vehicle. Most any metal connection point common to the vehicle frame should be suitable.

STEP 3

Get the air tank and mount two 1/4" NPT male connectors into the air tank ports (see Figure "A").

Select a location for mounting the air tank. This location should be protected to prevent damage from flying rocks or debris. Mark and drill two 7/16" holes 2-1/2" apart. Bolt the tank in place using the 3/8"-16 x 1-1/2" hex bolts, washers and lock nuts provided. Be sure clear access is provided to the two air ports. (SEE CAUTION NOTE).

CAUTION:

The air tank supplied with this kit should be protected. Dents or punctures could cause air leaks, personal injury or property damage. Do not exceed 120 psi in the tank.

STEP 4

Measure a length of air line tubing to go from the compressor to the tank and cut as squarely as possible. A ragged or angled cut can cause a leak in the system. Do not fold or kink the air line tubing.
