Installing the Load Controller

ag

e System

GETTING STARTED

This part of the installation should be done after the air spring kit is installed. If you have any questions, please call Air Lift customer service at (800) 248-0892.

If you are adding this control system to an Air Lift LoadLifter5000 application, then no modifications to the low pressure sensor are necessary. If you are adding this control system to an Air Lift 1000 or RideControl application, and if your specific application requires a minimum of 10 p.s.i., then it will be necessary to adjust the low pressure sensor to 10 p.s.i.

To increase the pressure in the low pressure sensor, remove the rubber plug with pliers

(fig. 7). Using an alien wrench, turn the screw clockwise 4 1 /4 turns (fig. 8). Push the rubber plug back into the top of the low pressure sensor. Proceed with the step by step installation instructions.

Remove rubber cap

Turn alien screw 4 'A turns clockwise

RECOMMENDED COMPRESSOR LOCATIONS

Important

LOCATE COMPRESSOR IN DRY, PROTECTED AREA ON VEHICLE.

DIRECT SPLASH OR EXCESSIVE MOISTURE CAN DAMAGE

THE COMPRESSOR AND CAUSE SYSTEM FAILURE.

Disclaimer: If you choose to mount the compressor outside the vehicle please keep in mind the compressor body must be shielded from direct splash and the intake should be snorkeled inside the vehicle. If the compressor does not include a remote mount air filter or if mounting the compressor outside the vehicle, make sure to orient the compressor intake filter so that all moisture can easily drain.

Please also remember...

• To avoid high heat environments

• To avoid mounting the compressor under the hood.

• To check to be sure the compressor harness #2 will reach the compressor and connect to harness #1.

The compressor can be mounted in any position — vertical, upside down, sideways, etc.

(please refer to the instruction manual).

NOTE

NOTE

A

NOTE

CAUTION

1. Install the gauge pod (figs. 3, 4 & 5). Select a convenient mounting location that has a sturdy rigid surface. The bottom edge of the dash on either side of the steering wheel is a good location. Attach the gauge pod to the selected location with the black self-tapping screws.

Optional dash mounting bracket and hardware also included (fig. 6).

2. Connect the harness to the gauge pod. a. Connect the color coded wires to the gauge harness as shown in the attached schematic. b. Connect the low pressure switch assemblies as shown in figures 2 and 9. c. Do not connect the power wire at this time. d. The wiring harnEss also connects the gauge pod to the low pressure sensor assembly.

The low pressure sensor protects the air springs from failure resulting from low pressure in the unloaded condition. This sensor is preset to maintain a MINIMUM pressure of 5 psi in the air springs unless the setting was changed in the "Getting

Started" section. The sensor measures the pressure in each spring and turns on the compressor if the pressure falls below the set psi. e. Screw ground eyelet to firewall or other electrical ground in the cab.

The sensor should be located under the dash inside the vehicle and secured with the provided tie straps.

3. Install the compressor unit. a. Hold the compressor in the recommended location (fig. 10 or 11). b. For box frames: In some cases the frame section will not be wide enough to mount the compressor legs flat to the rail. Refer to figs. 10 and 11 in this situation.

DO NOT DRILL ANY HOLES INTO THE FRAME OR THE FLOOR BOARD BEFORE

CHECKING FOR HYDRAULIC LINES, GAS LINES, AND/OR ELECTRICAL WIRES

THAT MAY NEED TO BE MOVED ASIDE. ALSO, WHEN ATTACHING TO THE FLOOR

BOARD, IT IS IMPORTANT TO CHECK WHERE THE SCREWS PROTRUDE THROUGH

THE FLOOR BOARD. IT MAY BE NECESSARY TO TRIM OR COVER THE TOP OF THE

SCREWS INSIDE THE VEHICLE. A SEALER SHOULD BE USED AROUND THE SCREW

TO PREVENT THE ELEMENTS FROM ENTERING THE CAB AREA.

STANDARD DUTY COMPRESSOR MOUNTING (FIG. 1 - A1, 10)

In some cases the mounting area does not provide enough room to use a drill to drive in the screws. It may be necessary to use the mounting brackets as a template to drill 13/64" holes through the frame first and then use a 7/16" nut driver to install the self tapping screws.

(A2) Heavy Duty Compressor

1. Remove the nut from the leader hose and install over air line from check valve assembly.

2. Push the air line from the check valve assembly into the barbed fitting on the compressor leader hose

.

3. Slide the nut over the fitting and tighten securely (fig. 13).

4. Route the harness to the compressor. a. Use existing grommets in the floorboard or firewall to route the harness from the cab to the frame mounted compressor. b. In some cases, a hole may have to be drilled to allow access for the harness. Drill a 1" diameter hole and install the provided grommet (fig. 14). It will be necessary to seal any grommets or holes that have been cut, drilled or removed so as not to allow elements to enter the cab area of the vehicle.

After the hole is drilled and before you route the harness to through the firewall, insert the grommet and "walk" the material around the inside edge of the drilled hole. You may have to trim the grommet to get an exact fit.

(The flexible grommet is in the sealed parts package.) c. When routing the wiring harness, it should not be routed so as to lay on, or near, the exhaust pipe/muffler/catalytic convertor of the vehicle. Routing along the top of a crossmember or over a heat shield is recommended.

5. The next connection is between each air spring and the air line "T' fitting. a. With the air springs deflated, use a hose cutter to cut the air line already installed between the air springs and the inflation valves. b. Install the provided "T" fittings (fig. 1) by pushing the air line into each leg of the '7" until you feel a definite "click". Each line should go in 9/16". c. Connect a single length of air line to the open leg of the "T". Connect as shown in the pneumatic schematic. d. Route the air line across the chassis from the far side over the exhaust system heat shields and along the frame up to the compressor. Avoid heat sources, sharp edges, and tight bends.

e. Route air lines into cab from "T" fitting and attach to pressure switch assembly as shown in the pneumatic schematic. f. Route air lines from low pressure switch to gauge barb. g. Press air line over gauge barb. Water or lube may assist in securing air lines over the barb. A circular motion will assist in installation.

6. Connect the power wire to fused ignition. a. Route it to the vehicle fuse box. b. Determine which open terminal (accessory, etc.) works only when the key is in the

"on" or accessory position (or refer to the owners manual for an available accessory fuse). The terminal should have an amperage rating higher than the 15 amp in-line fuse. c. Connection to the fuse terminal will depend on what type of fuse your vehicle uses.

If your vehicle uses the barrel type fuse, use adapter #1. If you have the standard spade type fuses, use adapter #2. Many late model vehicles use a smaller spade type fuse which requires adapter #3 (fig. 15). If adapter #1 or #2 are used, it will be necessary to cut off the 1/4" female connector attached to the power wire and crimp the smaller 3/16" female connector supplied with this kit.

Connect adapter to "HOT" side of the fuse. With the ignition on, the compressor will turn on and fill the system to 10 p.s.i. before shutting off.

7. Press the off/on button to inflate both air springs and use the small deflate button to adjust the pressure. Inflate to 30 p.s.i. (20 p.s.i. for Air Lift 1000 kits). Check all fittings and inflation valve cores with a solution of 1/5 dish soap to 4/5 water in a spray bottle for leaks.

IMPORTANT: If the compressor runs continually or often, then there is a leak. Disconnect the compressor at the fuse box and test for leaks with a soapy water solution.

NEVER RUN THE COMPRESSOR LONGER THAN FOUR MINUTES CONTINUOUSLY.

ALLOW AT LEAST FIVE MINUTES FOR COOL DOWN BEFORE STARTING THE

COMPRESSOR AGAIN.

Frequently asked question

Q. Will installing air springs increase the weight ratings of a vehicle?

No. Adding air springs will not change the weight ratings (GAWR, GCWR and/or GVWR) of a vehicle. Exceeding the GVWR is dangerous and voids the Air Lift warranty.

Q. Is it necessary to keep air in the air springs at all time and how much pressure will they need?

The minimum air pressure should be maintained at all times. The minimum air pressure keeps the air spring in shape, ensuring that it will move throughout its travel without rubbing or wearing on itself.

Q. Is it necessary to add a compressor system to the air springs?

No. Air pressure can be adjusted with any type of compressor as long as it can produce sufficient pressure to service the springs. Even a bicycle tire pump can be used, but it's a lot of work.

Q. How long should air springs last?

If the air springs are properly installed and maintained they can last indefinitely.

Q. Will raising the vehicle on a hoist for service work damage the air springs?

No. The vehicle can be lifted on a hoist for short-term service work such as tire rotation or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the tension off of the air springs.

Tuning the air pressure

Pressure determination comes down to three things — level vehicle, ride comfort, and stability.

1. Level vehicle

If the vehicle's headlights are shining into the trees or the vehicle is leaning to one side, then it is not level (fig. 16). Raise the air pressure to correct either of these problems and level the vehicle.

2. Ride comfort

If the vehicle has a rough and harsh ride it may be due to either too much pressure or not enough (fig. 17). Try different pressures to determine the best ride comfort.

3. Stability

Stability translates into safety and should be the priority, meaning the driver may need to sacrifice a perfectly level and comfortable ride. Stability issues include roll control, bounce, dive during braking and sponginess (fig. 18). Tuning out these problems usually requires an increase in pressure. frs.

Guidelines for adding air:

1. Start with the vehicle level or slightly above.

2. When in doubt, always add air.

3. For motorhomes, start with 50-100 p.s.i. in the rear because it can be safely assumed that it is heavily loaded.

4. If the front of the vehicle dives while braking, increase the pressure in the front air bags, if equipped.

5. If it is ever suspected that the air bags have bottomed out, increase the pressure (fig.

19).

6. Adjust the pressure up and down to find the best ride.

7. If the vehicle rocks and rolls, adjust the air pressure to reduce movement.

8. It may be necessary to maintain different pressures on each side of the vehicle. Loads such as water, fuel, and appliances will cause the vehicle to be heavier on one side

(fig. 20). As much as a 50 p.s.i. difference is not uncommon.
