Preparation
1. Analyze the 5th Wheel. Determine where the rear jack brackets, controller and touchpad will be mounted on the 5th Wheel. The rear jack brackets should be mounted approximately 1′ behind the rear axle hanger and be aligned with each other. Jack brackets may already be pre-installed by Lippert. The controller should be mounted in an under-floor compartment, as far forward as possible, in the center of the 5th Wheel (if possible), and in compliance with RVIA Gas Codes, as the controller connections are not spark-proof. The touchpad should be mounted in a compartment on the side of the 5th Wheel so that the operator will have a view of the hitch pin while using the touchpad. The touchpad MUSt also be protected from the elements.
Note: The landing gear will be installed to the frame of the 5th Wheel by Lippert.
Criteria for Determining Use of Ground Control® 4-Point or 6 Point System
4-Point Application
Use the 4-Point application if the distance between the center of the landing gear footpad and the center of the rear jack footpad will be less than 20′ (Fig. 1).
Fig. 1
< 20′
6 Point Application
Use the 6 Point application if the distance between the center of the landing gear footpad and the center of the rear jack footpad will be 20′ or greater (Fig. 2).

Determining the Mounting Position of the Controller and Rear Sensor
Controller
The controller has a limited mounting area for proper performance. At the center of the frame (signified by the blue dotted line in figure 3) and at the center of the landing gear (signified by the black dotted line) 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, while still being inside the compartment. This area is signified by the green dotted box labeled Section A in figure 3.

1. Determine position and ground clearance requirements for the rear jacks (Fig. 6D). The rear jack brackets (Fig. 6B) should be mounted approximately 1′ behind the rear axle hanger and be aligned with each other.
Standard Jack
optional Short Jack
Note: When fully retracted, the rear jacks should be mounted to achieve a ground clearance equal to the departure angle or a minimum of 7″ to enable maximum level correction (Fig. 5). 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 (Fig. 6B) locations on the main frame rail.
3. Clamp the bracket to the main frame rail (Fig. 6A) in the marked position.
4. Weld the bracket to the main frame rail (Fig. 6A).

Controller
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. The compartment where the controller will be installed should be as far forward on the 5th Wheel as is possible and the controller must be installed in compliance with RVIA Gas Codes, as the controller connections are not spark-proof. For optimal performance, the controller should be positioned directly in the center of the 5th Wheel, but may be offset if necessary. The arrow on the label of the controller must point to the front of the 5th Wheel (Fig. 12).
Note: There are 4 different options for the controller, depending on whether a 4-point or 6-point system is being used and …whether the controller has a Bluetooth connectivity option: 803280 – 4 point w/o Bluetooth, 2021018954 – 4 point w/ Bluetooth, 803279 – 6 point w/o Bluetooth and 2021018951 – 6 point w/ Bluetooth
1. Measure the ceiling of the compartment where the controller will be placed and mark the center point on the ceiling.
2. Using four #8 x 1″ wood screws (Fig. 13B), attach the controller (Fig. 13A) to the ceiling of the compartment, centered over the marked centerline of the compartment, if possible.
3. Attach the power and ground harnesses to the corresponding posts on the controller and then connect them to the correct posts on the house battery.

Basic Jack operation
Be sure to park the 5th Wheel on solid, level ground. Clear all jack landing locations of debris and obstructions. Locations should also be free of depressions. When parking the 5th Wheel on extremely soft surfaces, utilize load distribution pads under each jack. People and pets should be clear of 5th Wheel while operating leveling system. Never lift the 5th Wheel completely off the ground. Lifting the 5th Wheel so the
wheels are not touching the ground will create an unstable and unsafe condition.
Landing gear (front jacks) can be operated any time the system is “ON”. By pushing the “FRONT” button (Fig. 18G), both front jacks can be extended. By pushing either the “FRONT” and “LEFT” (Fig. 18H) or “FRONT” and “RIGHT” (Fig. 18I) buttons, the individual front jacks can be extended. If the touchpad is put in the retract mode, indicated by the orange illuminated LED next to the “RETRACT” button (Fig. 18D), the front jacks can be retracted together by pushing the “FRONT” button (Fig. 18G) or individually by pressing “LEFT” (Fig. 18H) or “RIGHT” (Fig. 18I) buttons, while simultaneously pressing the “FRONT” button (Fig. 18G).
Middle jacks, if equipped, can not be extended or retracted in standard mode or manual mode. Middle jacks can only be operated in the special jack code error mode. In order to operate the middle jacks press “LEFT” (Fig. 18H) and “RIGHT” (Fig. 18I) buttons simultaneously.
The rear jacks can only be extended when the touchpad is in the manual mode. Once system is in manual mode, pressing the “REAR” button (Fig. 18J) will extend both rear jacks at the same time. To extend individual rear jacks, press the “LEFT” (Fig. 18H) or “RIGHT” (Fig. 18I) buttons while simultaneously pressing the “REAR” button (Fig. 18J), depending on which jack needs to be operated. If the touchpad is put in the retract mode, indicated by the orange illuminated LED next to the “RETRACT” button (Fig. 18D), the rear jacks can be retracted together by pushing the “REAR” button (Fig. 18J) or individually by pressing either the “LEFT” (Fig. 18H) or “RIGHT” (Fig. 18I) buttons, while simultaneously pressing the “REAR” button (Fig. 18J).
Note: If the rear jacks will not operate individually using the method described above, but they operate properly when Auto Level is performed, the Twist Prevention Protection system has locked out the operation to prevent damage to the frame of the 5th Wheel.

Homing Jacks
1. When components are added or replaced the system will need to be homed. Run the system by pressing “FRONT” (Fig. 18G). A special jack error code should occur. If not, introduce the special jack error code.
Note: To introduce an error, disconnect 1 of the hall effect sensor wires from the controller. After attempting to operate the disconnected jack, the touchpad screen will display an error. Reconnect the hall effect sensor wire.
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. 18G) to extend the front jacks (if required). B. Press “REAR” (Fig. 18J) to extend the rear jacks (if required). C. Press “LEFT” and “RIGHT” (Figs. 18H and Fig. 18I) 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 touchpad screen. This is typically caused by wiring interruption.
Zero Point Calibration
The “Zero Point” is the programmed point that the 5th Wheel 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 touchpad. 1. In manual mode, run the jacks to level the 5th Wheel. This is best achieved by placing a level in the
center of the 5th Wheel 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 5th Wheel is level, turn off the touchpad. 3. With the touchpad off, press and release the “FRONT” button (Fig. 18G) 5 times and then press and release the “REAR” button (Fig. 18J) 5 times. 4. The touchpad will flash and beep and the display will read “ZERO POINT CALIBRATION ENTER to set, Power to Exit” (Fig. 19). 5. To set the current position as the zero point, press the “ENTER” button (Fig. 18C). 6. LCD display will read “Zero point stability check” (Fig. 20). 7. LCD display will read “Zero point set successfully” once process is complete (Fig. 21). 8. The system will set this point as its level state and the touchpad will turn off.

Auto Level
After unhitching from tow vehicle and parking the vehicle at a safe distance away from the 5th Wheel, press the “ON/OFF” button (Fig. 18K) and then press “AUTO LEVEL” (Fig. 18F).
Note: Once the automatic leveling cycle has been started, it is important that there is no movement in the 5th Wheel until the 5th Wheel has completed the leveling process. Failure to remain still during the leveling cycle could have an effect on the 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 5th Wheel above level.
Auto Level Sequence
1. When Auto Level Sequence begins, the front of the 5th Wheel will lower slightly to a point below level. 2. Rear jacks will be grounded. 3. A side-to-side leveling sequence occurs.
Note: At this point on the 6-Point System, the two middle jacks are grounded to stabilize the 5th Wheel. The two middle jacks do not level the 5th Wheel.
4. Each jack will perform a final grounding touch. 5. LCD will read “AUTO LEVEL SUCCESS” (Fig. 23). 6. LCD will then read “READY Jacks: Down” (Fig. 24A), and the green LED at the center of the four jack
buttons will be illuminated (Fig. 24B).
