FITTING INSTRUCTIONS
AC8112
It is recommended that only a properly qualified person installs the product and carries out maintenance. If you are not
qualified and attempt to carry out such work ensure that all safety equipment is used and safety standards are met.
Ensure that you have read the full Product Manual before attempting to fit the product.
Ensure the Product Manual is kept with the vehicle and that any vehicle owner and/or operator are fully advised on the
system and its operation before attempting to drive or operate it.
DO NOT connect any electrical components to the vehicle without preparing the electrical system as per the vehicle
manufacturer’s instructions. Connecting without preparing the vehicle could lead to component failure, vehicle damage
or fire.
If you use a sharp utilityknife or razor blade great care must be taken in all cases not to cut yourself during this operation.
Air compressors get hot - avoid any flammable liquid or burn risk areas.
The air tank is rated to a maximum working pressure of 150 psi (10 bar) and this is never to be exceeded.
Incorrect use of this product can result in damage to the components associated parts
and/or the vehicle, which is not covered under warranty.
Ensure suspension airbags are maintained at the stated ride height at all times and maintain the minimum pressure
required and never exceed the maximum, as required by the particular airbag product.

GENERAL ADVICE
AIRLINE TUBING & FITTINGS - GENERAL NOTES
CUTTING
Only cut the airline tubing with a sharp blade making the cut as square as
possible.
Always trim the tubing before re-inserting into the fitting.
If you use a sharp utility knife or razor blade great care must
be taken in all cases not to cut yourself during this operation.
Contact Airbag Man for our recommended tube cutter tool.

CONNECTING & REMOVING
To connect:
Push the cleanly trimmed tubing firmly into the fitting as far as possible.
To remove:
First release the air pressure from the system.
To withdraw the tubing, push and hold the collar on the fitting away from the tube and pull out the tubing.
In confined spaces an open ended spanner can be used to evenly depress the collar and remove the airline tubing.

STEP 1 –PREPARE THE VEHICLE
Please note it may be necessary to remove components from the vehicle to fit this kit, ensure this is carried out according to the vehicle
manufacturer’s instructions regarding electrical connection and component positioning and mounting.
DO NOT connect any electrical components to the vehicle without preparing the electrical system as per the vehicle
manufacturer’s instructions. Connecting without preparing the vehicle could lead to component failure, vehicle damage
or fire.

STEP 2 –POSITION AIR COMPRESSORS
MOUNTING LOCATION
Select a mounting position considering the following:
1. Mounting surface needs to be Flat, Rigid and Secure (preferably horizontal).
2. As close to the Battery as possible. It is better to use more air line tubing than more electrical wiring as longer runs of wiring
require heavier wiring to maintain voltage.
3. Cool location away from Heat Sources with good natural ventilation.
4. Protected location - avoid positions that objects may strike and where excessive dust or debris can collect.
5. Water ingress will damage the air compressor - the air filter may need remote mounting in an elevated position, away from
the elements.
The outlet of the compressor must be routed to ensure condensation does not drain back to the compressor.
Air compressors get hot - avoid any flammable liquid or burn risk areas.
STEP 3 –MOUNT AIR COMPRESSORS
1. Disconnect ground (-i.e. earth) cable from the vehicle's
battery(s).
2. Temporarily position the air compressors where they will be
mounted and mark the mounting bolt hole positions. Check air
filter position and hose routing as required.
3. Mount the air compressors using the supplied bolts, washers
and nuts as shown.
NOTE: The rubber isolators must be orientated correctly for best
performance, refer to the specific compressor installation
instructions
A. Compressor Leg & Isolator
B. Mounting Bolt
C. Flat Washer
D. Locking Nut
STEP 4 –CONNECT AIR COMPRESSORS INLET FILTERS
1. Confirm the air filter configuration based on the compressor
mounting location.
2. If in a protected location the filter can be mounted directly to the
compressor inlet as shown to the right.
3. If the compressor is mounted where water or debris ingress
may occur the air filter must be remote mounted using the
supplied parts as shown below. The same barb connection
technique can be used as shown for the paddle switches.
4. Ensure air filter and airline mounting is secure and leak free.
The air filter element must be checked regularly and
replaced as required. A blocked air filter will effect
compressor performance and lead to compressor failure
which is not covered under warranty.

Air filter condition is directly related to compressor
location, driving environment and compressor usage.
For high debris applications inspect the air filter every
month.
STEP 5 –COMPRESSORS WIRING AND AIRLINE CONNECTION
Use the supplied Air and Electrical Connections diagrams as a guide for your dual compressor air line and wiring connections. Use
the instructions supplied with your Airbag Man Air Control system kit for specific air line and wiring connections.
NOTE: Only one Pressure Switch is to be installed and this is wired to activate both of the supplied relays as shown. Where
possible, we recommend for each compressor outlet to be connected at opposite ends of a common air tank for best output
performance.
STEP 6 –USE & MAINTENANCE
Periodically check that the air filter for the air compressors is clean. Spare filters are provided for replacements and they may be needed
often if the compressor is operating in a dusty environment.
Regularly clean dust and debris from the compressor fins and motor housing.
Periodically check the electrical and pneumatic connections are tight and not damaged.
Periodically check the fasteners for the compressor, tank and control panel are tight.
The air compressor is equipped with a permanently lubricated, maintenance-free motor. Never try to lubricate the air compressor.
If the air compressor runs for a long period of time it may turn off due to its internal Thermal Overload Protector. If this happens turn
the power off and allow the unit to cool for about 30 minutes. This will allow the protector to reset so you can safely resume use of the
compressor. In the event of the compressor repeatedly turning off early or blowing fuses check that the battery voltage is sufficient, the
wiring is suitable and in good condition, the pressure switch is not faulty and that the relay is working correctly.
If all the electrical components appear correct then check that the compressor had adequate ventilation and is clean. If problems still
occur the compressor may be worn out and in need of replacement.
CAUTION: Never touch the air compressor or fittings connected to the air compressor with bare hands during or
immediately after use. The leader hose (where fitted) and fittings connected to the leader hose or pump head will
become very HOT during and after use. If necessary wear heat resistant gloves to handle fittings, airline and leader hose.
Incorrect use of this product can result in damage to the components associated part and/or the vehicle, which is not
covered under warranty.
Ensure suspension airbags are maintained at the stated ride height at all times and maintain the minimum pressure
required and never exceed the maximum, as required by the particular airbag product.
