Congratulations on your purchase of a new Level Command
kit. This kit was designed to provide inflation control of your
air helper springs. This kit will be an asset to your vehicle,
meeting nearly all of your air supply needs.
Please take a few minutes to read through the instructions,
identify the components, and learn how to properly install your
Level Command kit.

NOTE ON CONNECTING THE AIR LINE TUBING:
Cut the air line tubing as squarely as possible. To connect
the air line tubing to the fittings, push the tubing into the fittings
as far as possible. If for any reason the tubing must be removed,
first release the air pressure from the air helper spring. Push the
collar toward the body of the fitting and the pull out the tubing.
To reassemble, make sure the tubing is cut squarely and push
the tubing back into the fitting.

N
:
The Level Command kit can be used with all air helper
spring products. If you are installing an air suspension system,
do not install the air line tubing to the air springs as stated in
the suspension system instruction manual. If you are adding
the Level Command kit to an existing air suspension system,
you will need to deflate the air springs and remove the air line
tubing.

ELECT A MOUNTING LOCATION FOR THE CONTROL PANEL
Select a mounting surface under the dashboard or other protected
location. Using the control panel as a template, mark each of the
mounting points with a center punch. Drill a 3/16" diameter hole on each
center mark see Figure "B". Do not attach the control panel at this
time.

REPARE THE COMPRESSOR

Install the push-to-connect male fitting into the check valve on the
compressor head see Figure "A". Tighten the fitting sufficiently to
engage at least two threads with pre-applied orange thread sealant. DO
NOT OVERTIGHTEN THE FITTING.

TEP
OUNT THE COMPRESSOR
3 - M
Begin by removing the negative battery cable. Select a convenient
location to mount the compressor. This location should provide ample air
flow and be protected from airborne debris and moisture. The mounting
surface should be rigid to support the compressor, such as under the hood
on a fender well or in a vented storage compartment. The compressor
is oil-less and can be mounted in any orientation necessary for installation.
Using the compressor as a template and a center punch, mark and drill
four 3/16" holes. Any burrs in the holes should be removed to prevent
damage to the rubber isolators. Mount the compressor using the supplied
10 -32 x 1" machine screws, 10 -32 lock nuts, and 3/16" washers see
Figure "C". Maximum vibration isolation can be achieved by properly
mounting the compressor. The machine screw and nut should be
tightened only enough to bottom-out the brass insert see Figure "C".
DO NOT OVERTIGHTEN. Overtightening will crush the brass insert
and the rubber isolator, thereby reducing vibration isolation. Finally,
connect the black wire with the ring terminal from the compressor to a
suitable ground.

OUTE THE AIR LINE
4 - R
Before installing the air line tubing, ensure that there is no pressure
in the air springs. To release the air pressure, remove the valve core from
the manual inflation valves or release the pressure by using a tire gauge
to depress the valve stem.

OMPRESSOR TO CONTROL PANEL
Cut a piece of air line tubing that will reach from the control panel to
the compressor. Cut the air line tubing as squarely as possible and install
the tubing on to the barbed fitting on the back of the switch marked SUP
(supply) see Figures "A" & "D". Before attaching the air line tubing
to the control panel, soak the end (1") of the air line in hot water for a few
minutes to soften the tubing. Do not use pliers to work the tubing on to
the barbed fitting, as the tubing may be damaged. It may be necessary
to drill a hole in the firewall to route the tubing. Do not fold or kink the
tubing. Ensure that the tubing is protected from sharp edges when
passing through the firewall.
ONTROL PANEL TO AIR SPRINGS
B) C
Cut a length of air line tubing that will reach from the control panel to the rear of the vehicle. Slide the tubing as
far as possible onto the barbed fitting on the back of the gauge, see Figures "A" & "D". Do not use pliers to work
the tubing on to the barbed fitting, as the tubing may be damaged. Install a T-fitting on the opposite end of the tubing
at the rear of the vehicle. Route a length of air line tubing from the T-fitting to each air spring. Use the suppled nylon
ties to secure the tubing to the vehicle. Make sure that the tubing is protected from sharp edges when passing through
the firewall.

Place the air control panel on the dash where the holes were drilled in Step 1. Using the provided machine screws,
lock nuts, and washers attach the air control panel to the dashboard or selected mounting surface see Figure "B".

Install the relay within three feet of the compressor. Nylon ties
can be used to secure any excess wire and the relay neatly into
place. Route the white wire labeled “Switch Panel” to the control
panel. Connect the white wire to one of the white wires on the back
of the switch. The remaining white wire will be grounded to the
vehicle. Next, connect the orange wire labeled “Comp +” to the red
(positive) wire on the compressor. Connect the red, fused wire
labeled "Bat +" from the relay to the battery or another 12V (positive) source capable of supporting 20 amps. See Figure "A".

HECK THE SYSTEM
9 - C
With the Level Command kit and your air helper springs
installed, you are ready to test the system. Reattach the
negative battery cable. Turn on the vehicle's ignition. Push
the paddle switch up to inflate the air springs. The gauge will display how much air pressure is in the air springs. Inflate
the air helper springs to 70 psi OR the max operating pressure for the air springs, whichever is less, and check the fittings
for air leaks with an applied solution of soap and water. If a leak is detected at a tubing connection, check to make
sure that the tube is cut as square as possible and that it is pushed completely into the fitting. The tubing can easily be
removed from the fitting. First, release the pressure from the air spring. Push the collar towards the body of the fitting
and pull out the tube.
Note: If it is necessary to remove the air line from one of the barbed fittings, use a shaving motion with a sharp knife
to shave the air line until it is thin enough to pull off of the barbed fitting. DO NOT cut, scrape, or damage the fitting
or it may cause a leak path.
NOTE: If the system inflates the air springs normally but only releases the air pressure in the line and not
the air springs, the air lines are not properly installed on the switch and gauge. Switch the air lines making sure
the line from the air spring is connected to the gauge, and the line from the compressor is connected to the "SUP"
fitting on the switch.
SYSTEM OPERATION
The Level Command kit allows the air springs to be inflated from the inside of the vehicle. Push the paddle switch
up to inflate the air springs and push the paddle switch down to deflate the air springs.
