BEFORE STARTING THE INSTALLATION:

Read through this manual and ensure you can complete the installation once started.
It is recommended to use a good quality anti-seize on all fasteners. This will reduce the chance of corrosion on the fasteners and will help facilitate removal, if required at a later date.

PLEASE NOTE:
Using scissors or wire cutters to cut the nylon airline will distort the line and cause the connection to leak. THE AIRLINE MUST BE CUT OFF SQUARELY WITH THE NYLON HOSE CUTTER OR A SHARP UTILITY KNIFE.

CONTROL BOARD INSTALLATION

This kit is designed to be installed along the frame rail of pickup trucks, see Figure 1A.

Check for clearance along the frame rail to ensure that the kit will not interfere with anything once installed.

Fasten the control board to the two frame brackets using the supplied 5/16” cap screws, nuts and washers.

Torque the hardware to 23 N•m [17 ft-lbs]. Refer to Figure 1B.

Mount the control board as high as possible on the frame rail and in the orientation shown in Figure 1C on the following page.

Do NOT mount controller or compressor assembly directly on engine or other components exhibiting harsh vibration

Do NOT mount the controller or compressor assembly in areas where ambient temperature exceeds 70°C [158°F]

Securely install the Control Board Assembly onto the frame rail of the vehicle using 2 U-bolts, 4 flat washers, and 4 Nyloc nuts. (Refer to Figure 1C for configuration and assembly).

Check to ensure control board/compressor and mounting brackets do not pinch or interfere with vehicle component.

CONTROL BOARD HARNESS

Using Figure 2A as reference, route the red/black/white harness from the control board to the engine bay. Extend/trim the harness as necessary.

Strip the end of the black wire and crimp the supplied ring terminal to it.

Connect the ring terminal to the negative terminal of the battery.

If the negative terminal of the battery is not accessible, an external chassis ground may be used provided it has clean contact.

Use the blue heat shrinkable splice to connect the fuse holder to the red wire.

Crimp the male spade terminal to the other end of the fuse holder.

Use the blue 16-14 AWG T-tap and crimp it onto a 12VDC switched ignition source, then connect the male spade terminal to the T Tap.

The T-tap can be crimped onto a constant 12VDC source – giving the user the ability to control their air springs without having to power the truck on. The controller consumes approximately 35-80mA in standby mode, which will slowly discharge the battery.

COMPRESSOR RELAY HARNESS

Using Figure 2B (on the following page) as reference, find a location to mount the relay receptacle within 12” of the positive battery terminal. Route the red/black wires with plug along the control board harness and connect to the matching plug at the compressor. Use the supplied zip ties to secure both the compressor and control board harnesses away from heat sources and moving components.

Connect the ring terminal crimped to two black wires to the negative terminal of the battery.

If the negative terminal of the battery is not accessible, an external chassis ground may be used provided it has clean contact.

Connect the fuse holder to the positive terminal of the battery.

Locate the white wire on control board harness, trim the heat shrunk end and strip the end.

Connect this white wire with the white signal wire of the relay harness using the pre-installed red heat shrinkable splice.

PLUMBING

Refer to the system diagram on page 3 for the following instructions.

Use the supplied tube cutter to cut the airline. Using scissors may distort the line and cause the fitting to leak.

Connect the input of the solenoid block to the outlet of the compressor using a section of black airline.

Connect the air intake filter to the inlet of the compressor using a section of black airline. Mount the filter housing in a clean, dry area sheltered from road spray and debris.

Connect the inlet of the DRIVER side air spring to the LEFT port on the solenoid block using the red airline.

Connect the inlet of the PASSENGER side air spring to the RIGHT port on the solenoid block using the green airline. Ensure airlines between the control board and air springs are of equal lengths.

Use the supplied zip ties to secure the airlines away from heat sources and moving components

LEAK TEST

Inflate both air springs to 90 psi (60 psi for in-coil bags) and then use a mixture of dish soap and water on all air line connections to detect any air leaks. Large, expanding bubbles indicate a leak (as shown in Figure 5).

Repair as necessary and retest.

Inflate air springs to a predetermined value and on following day recheck pressure. If one or both of air springs have lost pressure, an air leak is present.

Leak must be repaired, and then retested until no leaks exist.

DISCLAIMER

Driving while distracted can result in loss of vehicle control that may lead to an accident, severe personal injury, or death.

The driver’s primary responsibility is in the safe and legal operation of a vehicle, and use of any handheld devices, other equipment, or vehicle systems which take the driver’s eyes, attention and focus away from the safe operation of a vehicle or which are not permissible by law should never be used during operation of the vehicle.

OPERATING YOUR VEHICLE WITH AIR SUSPENSION

Air springs have minimum and maximum recommended pressure requirements:

PART #	SPRING STYLE	SPRING TYPE	MIN PSI	MAX PSI
HP10189	In-Coil	STANDARD DUTY	5 PSI	70 PSI
HP10560	STANDARD DUTY
HP10001	Sleeve Style	STANDARD DUTY	10 PSI	100 PSI
HP10173	STANDARD DUTY
HP10199	STANDARD DUTY
HP10083	Single Convoluted	HEAVY DUTY	5 PSI	100 PSI
HP10083J	HEAVY DUTY with JOUNCE BUMPE	0 PSI* / 5 PS	100 PSI
HP10000	Double Convoluted	HEAVY DUTY	5 PSI	100 PSI
HP10000J	HEAVY DUTY with JOUNCE BUMPER	0 PSI* / 5 PSI	100 PSI
HP10068	Large Double Convoluted	HEAVY DUTY	5 PSI	100 PSI
HP10438	Large Double Convoluted	HEAVY DUTY	5 PSI	100 PSI
HP10438J	Double Convoluted	EXTREME DUTY	5 PSI	100 PSI
EXTREME DUTY with JOUNCE BU	0 PSI* / 5 PSI	100 PSI

For safe and proper operation, never operate the vehicle over the maximum listed PSI in the air springs. Staying under the
pressure limit will ensure maximum air spring life. Failure in doing so may result in damage to your vehicle and/or a void warranty.

It is recommended to check the air pressure in your air springs daily for fi rst couple of days to ensure a leak has not developed.

Air springs are designed to maintain the vehicle’s stock ride height with a load. Do not use the air springs as a means to lift vehicle
with no load. This will result in a harsh ride

SERVICING YOUR VEHICLE WITH AIR SUSPENSION

When lifting the vehicle with a fl oor jack or hoist on the frame, never allow the air spring to limit the travel of the axle. Try to always jack the vehicle on the axle. Suspending the axle with the air spring limiting the axle travel will damage the air spring and void the air spring warranty.
