3 System ailure to act in accordance with the following may result in death or serious personal injury. The use of the Lippert lectronic/ydraulic Leveling and Slideout System to support the coach for any reason other than which it is intended is prohibited by Lippert's Limited Warranty. The Lippert lectronic/ydraulic Leveling and Slideout System is designed for leveling the unit and extending/retracting slideouts and should not be used to provide service for any reason under the coach such as changing tires or servicing the system. Lippert Components, nc., recommends that a trained professional be employed to change the tire on the coach. ny attempts to change tires or perform other service while coach is supported by the Lippert lectronic/ydraulic Leveling and Slideout System could result in damage to the motor home and/or cause serious injury or death. NOTS: e sure to park the coach on solid, level ground. Clear all jack landing locations of debris and obstructions. Locations should also be free of depressions. When parking the coach on extremely soft surfaces, utilize load distribution pads under each jack. People and pets should be clear of coach while operating leveling system. e sure to keep hands and other body parts clear of fluid leaks. Oil leaks in the Lippert Leveling System may be under high pressure and can cause serious skin penetrating injuries. Never lift the coach completely off the ground. Lifting the coach so the wheels are not touching the ground will create an unstable and unsafe condition and may result in serious personal injury or death. System escription Note: Please read and study the operating manual before you operate the system. The Lippert lectronic/ydraulic Leveling and Slideout System is an electric/hydraulic system. 12VC electric motor drives a hydraulic pump that moves fluid through a system of hoses, fittings and jacks to level and stabilize the coach. The Lippert lectronic/ydraulic Leveling and Slideout System is totally integrated into the chassis of the coach at the manufacturer. There are no serviceable parts within the electric motor. f the motor fails, power unit must be replaced. isassembly of the power unit voids the warranty. Mechanical portions of the Lippert lectronic/ydraulic Leveling and Slideout System are replaceable. Contact Lippert Components, nc. to obtain replacement parts. Rev: Page 3 Untitled-1

4 Component escription The Lippert lectronic/ydraulic Leveling and Slideout System consists of the following major components: Lippert jacks are rated at a lifting capacity appropriate for your coach. ach jack has a 9 diameter (63.5 square inch) shoe on a ball swivel for maximum surface contact on all surfaces. (12 dia sq. in. shoe also available). ach jack is powered from a central 12VC motor/pump assembly, which also includes the hydraulic oil reservoir tank, control valve manifold, and solenoid valves. The Lippert lectronic/ydraulic Leveling and Slideout System is controlled electronically from the driver s seat of the coach. The control panel is mounted in the dash. The system can be operated in a manual mode or a fully automatic mode. The slideouts on this system are actuated by hydraulic cylinders integrated into the box of the slideout frames. Some rooms will have one cylinder per room, others will have two. Consult the manufacturer of the coach to find out the cylinder configuration on your unit. Your coach should be supported at both front and rear axles with jack stands before working underneath. ailure to do so may result in death or personal injury.

7 Level Zero Point Calibration efore auto-leveling features are available, the Level Zero point must be set. This is the point to which the system will return when an auto leveling cycle is initiated. To set the zero point (controller module must be fully secured in production-intent location), first use a carpenter's level to run a manual leveling sequence to get the vehicle to the desired level point; then activate the Level Zero point configuration mode. This mode is enabled by performing the following sequence: 1. Turn panel off. Then turn panel on. 2. Perform the following: Press the ront (ig. 5) switch 5 times. Press the Rear (ig. 5M) switch 5 times. 3. t this point all L outputs will blink, and the buzzer will be off. 4. You are now in L mode ready to set Zero Point. 5. With a carpenter s level, confirm coach remains in level disposition. n L MO, the leveling system is in MNUL MO and can be used to make any corrections to level the coach. 6. When coach is completely leveled manually, press the Retract ll (ig. 5P) switch 3 times to set the zero point. "Latched Out" Warning lashing ig. 6 LTC RROR mode is WT, CKS OWN, PRK RK, XCSS SLOP N LOW VOLT lights flashing (ig. 6). This error is caused by either of these circumstances: 1. attery voltage below 10.0V C. 2. Retract time over 67 seconds in auto retract. NOT: This is the only LTC RROR MO. NOT: ll revisions prior to controllers treat this error as regular RROR mode. To RST, push all 4 diamond-shaped jack buttons (ig. 6) at the same time. Rev: Page 7 Untitled-1

8 ir and uxiliary eature Configuration or iesel Units with irbag Suspensions ONLY: eature is entered ONLY after zero mode programming. t this point the WT L (ig. 5) will blink for 20 seconds. You are now in ir/uxiliary eature Configuration mode. To enable ir uxiliary features, perform the following: Press the RTRCT LL (ig. 5P) switch 3 times. User must do this within 20 seconds of entering this mode. To disable ir features, perform the following: rror Mode o nothing. fter 20 seconds, module will exit mode with features disabled. f any problem is detected with the jacks, the system will enter error mode. rror mode may be recognized by the blinking of LT, LVL and RT Ls. The following errors are detected by this system: ack over current/short circuit. ack under current/ open circuit. ack extending too long (ground not detected after 2 min). ack retracting too long (fully retracted not detected after 2 min). Out of stroke detection during auto cycle (if enabled). User larm Mode f the alarm system detects that the park brake has been disengaged while at least one jack is not fully retracted and the sensor value changes in any axis more than a predefined amount, the panel will signal this error to the user. When in alarm mode, all Ls will flash and the buzzer will beep. The Status Ls will show the system status. The system will perform an automatic retract. No other features are available in this mode. Miscellaneous The system will automatically shut down after 4 minutes of no operation. uto leveling cycle cannot be started until all jacks are fully retracted. Make sure jacks are retracted before attempting to auto level (unit will perform full retract automatically if jacks are not down on the request of an auto cycle). System will refuse any operation when a low voltage condition is present. System will automatically alarm and retract if park brake is disengaged and jacks are not retracted with any change in sensor readings. n alarm mode, the only available feature is to retract all jacks. Please note the Wait L shows the status of ir/ uxiliary features. Please note that the Ls blink differently when in special controller modes (error, alarm, and configuration). Learning how to recognize these modes is important. xcess slope L blinks whenever the Y axis (vehicle length) is over 5 o from programmed level point. Rev: Page 8 Untitled-1

9 Prior to Operation The leveling system should only be operated under the following conditions: 1. The coach is parked on a reasonably level surface. 2. The coach PRKN RK is engaged. 3. The coach transmission should be in the neutral or park position. 4. The ignition is in the run position, or engine is running. 5. e sure all persons, pets and property are clear of the coach while Lippert Leveling System is in operation. Operation Selecting Site When the coach is parked on an excessive slope, the leveling requirements may exceed the jack lift stroke capability. f the coach is parked on an excessive slope, the coach should be moved to a more level surface before the leveling system is deployed. utomatic Leveling Procedure NOTS: Refer to (ig. 5) for questions regarding location and functions of the Lippert Components nc. lectronic/ydraulic Leveling System.

27 Maintenance Preventative Maintenance Procedures 1. Change fluid in reservoir only every 36 months.. Check fluid only when jacks and slideouts are fully retracted.. lways fill the reservoir with the jacks and slideouts in the fully retracted position. illing reservoir when jacks are extended will cause reservoir to overflow into its compartment when jacks and slideouts are retracted. C. When checking fluid level, fluid should be within 1/4 of fill spout lip. 2. Check the fluid level every month. 3. nspect and clean all Pump Unit electrical connections every 12 months. f corrosion is evident, spray unit with W-40 or equivalent. 4. Remove dirt and road debris from jacks and slideout arms as needed. luid Recommendation The Lippert lectronic/ydraulic Leveling and Slideout System is pre-filled, primed and ready to operate direct from the manufacturer. utomatic transmission fluid (T) with exron or Mercon 5 or a blend of both is recommended by Lippert Components, nc. 5. f jacks are down and slideouts extended for long periods, it is recommended to spray exposed leveling jack and slideout cylinder rods with a silicone lubricant every seven days for protection. f your coach is located in a salty environment, it is recommended to spray the rods every 2 to 3 days.
