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: Orientating The Compressor For Best Fit
Installing the Compressor 2.2 Orientating the Compressor Outlet for Best Fit The CKMTA series compressors allow for configuring the outlet port to best suit the installation position and desired position of the outlet hose or coupling (see Fig 1). It is highly recommended to spend some time experimenting with different configurations prior to drilling the four mounting holes. - Page 7 Installing the Compressor Gently lift the cover upward from under the fan until it is just above the compressor motors. LIFT THIS END OF THE COVER UNTIL IT IS CLEAR OF THE MOTORS Figure 3. CLEARANCE BETWEEN COVER AND COMPRESSOR MOTOR ...

'Maximum Length of Tube' column above. 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 Installing the Compressor Assemble an extension tube with a ¼” NPT male fitting at one end and a ¼” NPT female end at the other. Install the tube inline with the air filter. NOTE : If the extension tube is being used due to the possibility of the compressor being exposed to water then Teflon tape or thread sealant should be used on the threads of the extension tube at the compressor end.

The Air Locker Manifold Kit is shown in Fig. 7 and... - Page 13 If the compressor is to be used for Air Locker activation and inflating several tires then fitment of the Air Locker Manifold kit mentioned in section 3.1.1 would be suitable. This allows for fitment of a hose coupling ARB #171402 as shown in Fig. 7 (which is available separately in Pump Up Kit ARB #171302).

- Page 17 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 18: 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 CKMTA12 compressor kit for 12V systems or the CKMTA24 for 24V systems. - Page 19 Mounting & Connecting the Electrical System 4.3.2 Power Connection To A 24V Vehicle / System Vehicles equipped with aftermarket ‘dual battery kits’ are not classified as NOTE : 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. The compressor should not come on again for a period of at least 15min. Air system recharging within that time period would indicate that a leak is present in the system.

Page 21: Electrical Fault Diagnosis
Testing & Troubleshooting 5.3 Electrical Fault Diagnosis The following describes an effective procedure for tracing an electrical fault in a CKMTA12 or CKMTA24 compressor which has been wired using a genuine ARB wiring loom (refer to the diagram in Figure 9.). All steps must be performed in the order listed here for an accurate assessment. - Page 22 Testing & Troubleshooting S T E P # [24V COMPRESSOR AND WIRING ONLY] Using a multimeter, check for 12V between a chassis ground and each of the two contacts in the mini-blade fuse holder. Was 12V detected at one of the two contacts? Reconnect the fuse into the holder.
- Page 23 WHT wire on the loom side of the plug (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.
