Page 4: Introduction
Although your ARB Air Compressor comes complete with all the step by step instructions you will need to install your new air source, ARB recommends that you have your ARB Air Compressor installed by a trained professional. Many ARB distributors around the world have been fully instructed in Air Compressor installations by ARB, and have gained a wealth of experience and skill from years of performing similar installations. -
Page 5: Installing The Compressor
Installing the Compressor 2.1 Identifying the Best Mounting Position Using the following points as guideline, identify a position on the vehicle or inside the cabin where the compressor can be safely and conveniently mounted. NOTE : The ideal position of the compressor should give consideration to all of the following points: 1. -
Page 6: Configuring The Compressor For Best Fit
Installing the Compressor 2.2 Configuring the Compressor for the Best Fit ARB’s CKMA series compressors are highly configurable to suit the most difficult mounting locations. Once the compressor’s ideal location has been determined, the shape of the unit can be configured in several ways to best suit the mounting position, provide best access to the ports, and look the most attractive once installed and wired. -
Page 7: Drilling & Mounting The Compressor
Installing the Compressor 2.3 Drilling & Mounting the Compressor Establish the mounting hole locations for the compressor by using the compressor backing plate as a template, or referring to Fig.3. for exact sizes. Figure 3. NOTE : The mounting bracket holes are slotted in a circular pattern allowing the backing plate and bolts to be partially rotated relative to the compressor. -

(10mm socket) to approximately 9 Nm [6.6 ft-lb] (Ref Fig.2.). 2.4 Installing the Solenoid(s) This step applies to the 12V solenoid that is packed with each ARB Air Locker differential. If the compressor is to be used for an alternate purpose then simply skip this step and plug or terminate the ports as required by the application. -
Page 9: Installing The Pressure Switch
Installing the Compressor 2.5 Installing the Pressure Switch Remove the plastic dust plug from the larger ¼ NPT port in the compressor manifold and discard. Generously apply Teflon paste/tape to the threads of the pressure switch and assemble it into the port and tighten with a wrench/spanner. NOTE : Pressure fittings do not require high torque to form a good air tight seal. - Page 10 Installing the Compressor NOTE : ARB does not recommend connecting the compressor intake to the air supply in a ‘snorkel’ or other part of the air ducting for engine aspiration. However, if an extension tube is used to relocate the compressor intake to...

Page 11: Connecting The Air System
NOTE : The flexible 5mm air line described here is supplied with each Air Locker kit and NOT with this ARB compressor kit. If you require air line to complete this installation then contact your ARB Air Locker distributor. Account for axle travel when running the line from the axle to a fixed point on the vehicle. -

Mounting & Connecting the Electrical System 4.1 Mounting the Actuator Switch(es) ARB compressor and Air Locker actuator switch(es) can be easily panel mounted inside the vehicle in a 21mm x 36.5mm [0.83” x 1.44”] rectangular cutout. NOTE : Air Locker actuator switches described here are supplied with each ARB Air Locker kit and NOT with the ARB compressor kit. -

Mounting & Connecting the Electrical System 4.2 Wiring the Actuator System ARB AIR COMPRESSOR WIRING LOOM (CKMA12 & CKMA24) Figure 7. - Page 15 Air Locker solenoid(s) to an ARB Air Compressor, all connections can easily be set up using only the supplied wiring loom (ARB #180409 shown in Figure 7.) Consulting the wiring diagram (Fig.7.) for wire colors, and the switch terminal illustration (Fig.8.), plug each of the female spade terminals onto their appropriate switch terminal.
- Page 16 Mounting & Connecting the Electrical System NOTE : If shortening the BLU-WHT wire, make sure not to remove the heat shrinked inline diode that protects sensitive electronics from current leakage. Insulate the junction area well with electrical tape. Route the 4 loose male spade terminals of the long section of loom through any panel work that separates the compressor mount position from the switches (e.g., the firewall separating the cabin from the engine compartment).

Page 17: Connecting The Power Wires
12 volt or 24 volt system, the DC motor of the compressor has been designed ONLY for use on one specific voltage system. Make sure you have the CKMA12 compressor kit for 12V systems or the CKMA24 for 24V systems. - Page 18 Mounting & Connecting the Electrical System 4.3.2 Power Connection To A 24V Vehicle / System NOTE : Vehicles equipped with aftermarket ‘dual battery kits’ are not classified as 24V systems. They require the 12 volt compressor kit, and connection to the primary battery only according to section 4.3.1.

Testing & Troubleshooting 5.1 Leak Testing With the vehicle parked and the engine off, turn the compressor on and wait until the air system is fully charged. NOTE : With the Air Locker(s) disengaged, the compressor should not have to recharge over time. -
Page 20: Electrical Fault Diagnosis
Testing & Troubleshooting 5.3 Electrical Fault Diagnosis The following describes an effective procedure for tracing an electrical fault in a CKMA12 or CKMA24 compressor which has been wired using a genuine ARB wiring loom (refer to the diagram in Figure 7.). All steps must be performed in the order listed here for an accurate assessment. - Page 21 Testing & Troubleshooting S T E P # Using a multimeter, check for MOTOR VOLTAGE between a chassis ground and the RED wire at the relay block (i.e., the wire leading directly from the fuse). Was MOTOR VOLTAGE detected? Proceed to STEP 6. Wiring fault between the fuse and the relay.
- Page 22 (not on the compressor side) and the negative (-) terminal of the battery [#1]. Did the resistance measure less than 1 Ohm? Intermittent wiring fault or internal compressor problem. Contact ARB. Wiring fault in the ground wire between the battery [#1] and the compressor motor. Replace wiring.
