Preparation
1. Remove all loose items from the front storage compartments
of the trailer.
2. Support the trailer at all four corners with jack stands
(or other adequate supports).
3. Remove the underbelly from the trailer and set aside.
Determining the Mounting Position of the Jack
Brackets and Components
1. Analyze the trailer. Determine where the jack brackets,
controller, touch pad, and rear sensor will be mounted on the
trailer.
A. Rear Jack Brackets: should be mounted approximately
12” behind the rear tires and be aligned with each other.
B. Middle Jack Brackets (if applicable): should be mounted
approximately 12” in front of the front axle hanger and
should be aligned with each other.
C. Controller: should be mounted to the ceiling of the front-
most storage compartment in the center of the trailer.
The controller has a limited mounting area for proper
performance. At the center of the frame (side to side) and
at the center of the landing gear (front jacks) is a center
point. From this center point, the controller can be mounted
12” out on either side and up to 3’ in front of or behind the
center point. This area is outlined in a green dotted box
(Fig. 3A).
Note: The controller MUST stay mounted inside a compartment
that is protected from the elements and in compliance with
RVIA Gas Codes, as the controller connections are not spark-
proof.
D. Touch Pad: should be mounted in a compartment on the
side of the trailer so that the operator will have a view of the
hitch pin while using the touch pad. The touch pad MUST
also be protected from the elements.
E. Rear Sensor: has a limited mounting area for proper
performance. The rear sensor MUST be in line with or
behind the rear leveling jacks, as well as in line with the
center of the frame. This area is outlined in a green dotted
line (Fig. 4A).

Rear and Middle Jacks
1. Determine position and ground clearance requirements for
the rear and middle jacks. The rear jack brackets should be
mounted approximately 12” behind the rear tire and be aligned
with each other. The middle jack brackets should be mounted
approximately 12” in front of the front axle hanger and be
aligned with each other.
Note: When fully retracted, the rear and middle jacks should be
mounted to achieve a ground clearance equal to the approach
or departure angle or a minimum of 7” to enable maximum
level correction. Any additional ground clearance added to
the jack location will decrease the amount of level correction
available to the system.
2. Mark jack mounting bracket locations on the main frame rail.
3. Using a 5/16” drill bit, drill through the frame at the marked
positions.
4. Using the included self-tapping bolts, mount the brackets
to the frame. Tighten the bolts to no more than 75 ft-lbs of
torque. Four bolts will be installed on the outside of the main
frame rail (Fig. 8). Two bolts will be installed on the underside
of the main frame rail, up through the horizontal plate on the
backside of the jack mounting bracket (Fig. 9).
Note: The horizontal plate of the bracket will have four pre-
drilled holes, however, only two self-tapping bolts are
necessary for installation. The two holes chosen MUST be
directly across from each other.
5. Bolt the rear and middle jacks to the mounting brackets using
six bolts and nuts per jack. Tighten the bolts to 90 ft-lbs of
torque (Fig. 8).
6. Connect the wire harnesses to the leveling jack motor
wires and run the harnesses to the compartment where the
controller will be mounted.
Note: LCI recommends zip-tying the harnesses tight against
the rear jack motors to prevent damage to the harnesses.

Rear Sensor
Note: The rear sensor (Fig. 10) MUST be installed on a
crossmember in line with or behind the rear jacks, centered
curbside to roadside on the trailer with the arrows on the top
of the sensor pointing the correct direction (Fig. 10 Detail).
1. Dry t the mounting plate (Fig. 11A) and the rear sensor (Fig.
11B) to the crossmember (Fig. 11C). The pre-drilled holes in
the plate are for mounting the rear sensor to the plate. Mark
on the plate where the rear sensor will set. Space between
the sensor and the crossmember MUST be left so the wire
harness will not be pinched.
Fig. 10 Detail
2. Attach the rear sensor (Fig. 12B) to the mounting plate
(Fig. 12C) using two #8 - 18 x 1” self-drilling screws (Fig.
12A). Orientation is imperative for the correct operation of the
leveling system.

Installation - Controller
Note: Prior to starting this portion of the installation, double
check that all of the harnesses are properly and securely
connected to the rear jacks, landing gear, and rear sensor.
Once those connections have been checked, reattach the
underbelly to the frame of the trailer in the same position
from which it was removed. If any tears are present in the
underbelly, seal with waterproof tape. Once the underbelly is
secured, the installation may be continued.
1. Measure to the center of the trailer from inside the
compartment where the controller will be placed, and mark
the center point on the ceiling. The controller MUST be
positioned directly in the center of the trailer with the arrow on
the label of the controller facing the front of the trailer. (Fig.
15).
2. Using four #8 x 1” wood screws, attach the controller to
the ceiling of the compartment, centered over the marked
centerline in the compartment (Fig. 16).
3. Attach the power and ground harness to the corresponding
posts on the controller and then connect them to the correct
posts on the house battery.
4. Connect all jack harnesses to the appropriate connectors on
the controller.
Note: The compartment where the controller will be installed
should be as far forward on the trailer as is possible and the
controller MUST be installed in compliance with RVIA Gas
Codes, as the controller connections are not spark-proof.
Note: For optimal performance, the controller should be
positioned directly in the center of the trailer, but may be offset
if necessary (Fig. 3A). The arrow on the label of the controller
MUST point to the front of the trailer (Fig. 15).
Note: Some 6-point controllers do not have orientation arrows
for the front of the trailer. When installing those controllers,
ensure that the port labeled “LEFT FRONT” is pointing to the
left-hand front of the trailer. This will ensure proper orientation
and function of the controller.

performance of the leveling system.
Note: In order for Hitch Recognition feature to function, the auto
level sequence MUST be started with the front of the trailer
above level.
Auto Level Sequence
1. When Auto Level Sequence begins, the front of the trailer will
lower to a point near level.
2. Rear jacks will be grounded.
3. A side to side leveling sequence will occur.
Note: At this point on the 6-point system, the two middle jacks
will be grounded to stabilize the trailer. These two jacks do not
level the trailer.
4. Each jack will perform a nal grounding touch.
5. LCD will read “AUTO LEVEL SUCCESS” (Fig. 24).
6. LCD will then read “READY Jacks: Down” (Fig. 25A), and
the green LED at the center of the four jack buttons will be
illuminated (Fig. 25B).
Note: If the AUTO LEVEL sequence does not perform as
described, place the system in manual mode and test that the

Special Jack Error Codes
To clear one of the error codes listed below:
1. Correct or otherwise repair the issue (see the table below).
Note: In order to clear the special jack error code the jacks need
to be “homed.” In order to “home” jacks, each jack MUST be
able to retract a minimum of 6”.
2. Extend all jacks to reach the 6” of minimum retract needed.
A. Press “FRONT” (Fig. 22G) to extend the front jacks (if
required).
B. Press “REAR” (Fig. 22J) to extend the rear jacks (if
required).
C. Press “LEFT” and “RIGHT” (Fig. 22H and Fig. 22I)
simultaneously to extend the middle jacks (if equipped and
required).
3. Press and hold the retract button until all of the jacks begin to
retract. The jacks will retract until they reach the hard current
limit.
4. The jacks are now “homed” and the special jack error code
will be cleared.
Note: If the jacks do not retract, an error should display on
the touch pad screen. This is typically caused by wiring
interruption.

Zero Point Calibration
The “Zero Point” is the programmed point that the trailer will return
to each time the Auto Level feature is used.
Note: Prior to starting this procedure, double check all connections
on the controller, jacks, and touch pad.
1. In manual mode, run the jacks to level the trailer. This is best
achieved by placing a level in the center of the trailer and leveling
it both front to back and then side to side. (See “Basic Jack
Operation” for instructions on how to manually operate the system).
2. Once the trailer is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button (Fig.
22G) ve (5) times and then press and release the “REAR” button
(Fig. 22J) ve (5) times.
4. The touch pad will ash and beep and the display will read “ZERO
POINT CALIBRATION ENTER to set, Power to Exit” (Fig. 33).
5. To set the current position as the zero point, press the “ENTER”
button (Fig. 22C).
6. LCD display will read “Zero point stability check” (Fig. 34).
7. LCD display will read “Zero point set successfully” once process is
complete (Fig. 35).
8. The system will set this point as its level state and the touch pad
will turn off.
Conguring the Remote
1. Turn the remote on by pressing and releasing the large silver
button at the bottom of the remote (Fig. 36A). If the remote
has never been congured, it will display the “Cong” button

after the initial programming, push the silver button 5 times
(Fig. 36A).
2. Press the “Cong” button on the touch screen to begin
conguring the remote (Fig. 36B).
3. Using the arrow buttons at the bottom of the screen, navigate

select YES. If not, select NO at this time (Fig. 38).
B. After all the functions have been assigned a “title,” the next
screen will ask: “Congure Leveler Type 1?” (Fig. 39) and
then “Congure Leveler Type 2?” (Fig. 40) will appear. If
syncing the transmitter to a LCI Level Up, Ground Control®
or Motorized Dual Sensor system, select “Yes” for Type
1 and “No” for Type 2. If you will not be syncing the
transmitter to either of these leveling systems select “No”
for both Type 1 and Type 2.
8. A conrmation screen will appear showing all of the
congured functions (Fig. 41). If the trailer does not have an
LCI Multifunction Wireless system installed, the screen will
