The above specification are based on an operating voltage of between 12 & 14 volts (i.e. the vehicle's engine must be running). The company reserves the right to adopt, without prior notice, specifications other than those set forth above. The ARB air compressor is designed to operate under normal conditions. Prolonged use over 45 minutes in elevated temperatures above 40C may result in damage. When used to inflate in these conditions we recommend it be allowed to cool down after a maximum running time of 45 minutes.

When the compressor is operating the Air Locker(s), or used to inflate in dusty conditions, the compressor will draw in dust. Ensure the air filter is cleaned after use in these conditions. Caution should also be observed when fording rivers to ensure the compressor is protected from ingesting water.

Locate position in vehicle where compressor is to be mounted and use backing plate to mark position of holes.

Hold compressor in position and insert four hex head screws through through holes. Fit backing plate over screws, then fit washers and nuts. Tighten. Rotate compressor to desired position and tighten clamp bolt.

Screw nipple and solenoid valve (from Air Locker Kit) into spare 1/8" BSP port (remove plug first) using Loctite 569 or equivalent, then fit pressure switch as per diagram below. Connect loom and airline tube as per Air Locker instructions.

Note: If a second Air Locker is being installed the pressure switch must be temporarily removed to allow the solenoid valve to rotate.
