CAUTION! DO NOT PRESSURIZE YOUR TANK UNTIL YOU HAVE INSTALLED ALL NECESSARY PORT FITTINGS AND ACCESSORIES. • Apply sealant to threads of fittings prior to assembly and tighten each part with a wrench. • Do not over tighten if your port fittings are made from brass, since brass threads can be stripped. • Always release air from tank before servicing. WARNING: FAILURE TO DRAIN TANK AND REMOVE CONDENSATION WILL CAUSE TANK TO RUST PREMATURELY.
Mounting the Tank: We have included 6 pieces of rubber bushings in your tank mounting hardware. You have the option of using two layers of rubber bushings on one of your tank lags to slightly tilt tank toward the drain cock port to improve drainage properties. Use the provided longer bolts, and corresponding washers, lock washers and nuts to mount the tank to a suitable chassis or other place on your vehicle.
• For compressors with remote filter mounting, select compressor mounting locations where air line can be routed from compressors’ 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 stainless steel braided leader hose.
10. To remove hose from the hose bracket, simply press down on the hose clamp release tab to release bracket clamp. 11. Tie compressor’s positive lead wires together and connect to pressure switch lead. 12. Make sure that your compressor setup is properly fused. Dual 325C compressors pull approximately 40 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.
Compressor Maintenance & Repairs 1. Periodically check all electrical and fitting connections. Clean and tighten as needed. 2. Periodically check all mounting screws. Tighten as needed. 3. Replace air filter element periodically. Replacement frequency depends on operating frequency and operating environment. For frequent use in dusty environment, you should replace air filter element more often. 4. Regularly clean dust and dirt from compressor. 5.
Pressure Switch Installation Tips 1. Both terminals of the pressure switch are positive (+) leads. One is connected to the compressor positive lead wire and the other to switched, fused power. Use of a relay is always recommended. 2. Never install your pressure switch in direct line from the inlet port coming from the compressor. Tank pressure could be misread by the pressure switch. Instead, mount the pressure switch on the tank where it receives air pressure reading from deflected air in the tank. 2.
malfunction and void warranty. The Dash Panel Gauge included in this kit is rated for 150 PSI. Do not pressurize gauge over 150 PSI. 1. Select Mounting Location for Dash Panel Gauge Select a mounting location with a rigid mounting surface such as the bottom edge of the dashboard. Use the gauge mounting panel as a template; mark off two mounting points to be drilled. Carefully drill two 13/64” diameter holes as marked. Do not mount Dash Panel Gauge at this time. 2.
There are two wires, one red and one black connected to the light bulb of the gauge. Connect the red wire to a suitable fused dash panel circuit. Use the quick splice connector included in the kit for wire connections. The black wire is to be connected to a suitable ground source. 6. Mounting the Dash Panel Gauge With all electrical and air line tubing routed and connected properly, mount the dash panel gauge using the two 13/64” nuts, bolts, and washers included with the Dash Panel Gauge.
Use a 1/4” NPT compression fitting on the “IN” side of the regulator receiving air from the air tank. On the “OUT” side of the regulator, you may install a 1/4” NPT quick connect coupler, or use another 1/4” NPT compression fitting to route the air line to the source of the item that pressure is being regulated to. If you are plumbing to air locking differentials, we have included two 1/8” BSP Female to 1/4” NPT Male Adapters for this use.
has a normally closed lever style air chuck at the end of its rubber hose. After connection to an air source such as an air tank via the quick connect stud preinstalled in the unit, air may be discharged from the gun by simply squeezing the inflation trigger. To check air pressure, simply release the trigger and check the onboard air pressure gauge. (Use contents of Package #7 for this installation step). 1.
