Fluid Recommendation

The Lippert Electronic Leveling System is pre-filled, primed and ready to operate direct from the
manufacturer. Type "A" Automatic Transmission Fluid (ATF) is utilized and will work. ATF with Dexron III® or
Mercon 5® or a blend of both is recommended by Lippert Components, Inc.
In colder temperatures (less than 10° F) the jacks may extend and retract slowly due to the fluid's molecular
nature. For cold weather operation, fluid specially formulated for low temperatures may be desirable. For a
list of approved fluid specifications, see TI-188.

Filling Directions

NOTE: Be sure landing gear are fully retracted prior to filling reservoir to prevent over-filling.
1. Remove Breather/Fill Cap
2.
Pour ATF into Breather/Fill opening.
NOTE: Do not allow any contamination into reservoir during fill process.
NOTE: Standard reservoir holds approximately 2 quarts (1.89 liters) of ATF.
3.
Fill to within ½" of top.
4.
Replace Breather/Fill cap when finished.
System is self-purging. By simply cycling the system 2-3 times, any air in the system will be forced back to
the reservoir and out of the Breather/Fill cap.

Troubleshooting

Power Unit

Before attempting to troubleshoot the Power Unit, make sure an adequate power source is available. The
unit batteries should be fully charged or the unit should be plugged into to A/C service with batteries
installed. Do not attempt to troubleshoot the Power Unit without assuring a full 12V DC charge.
The following tests require only a DC voltmeter (or DC test light) and a jumper lead.
1.
Attach voltmeter (or test light) leads to the negative and positive terminals on motor solenoid. Does
the meter indicate 12V DC? If YES, see Step 2; if NO see Step 3.
2.
If YES, at the motor, check the incoming leads to 12V DC (if necessary, disconnect leads at wire
splices). Does meter indicate 12V DC? If YES, Power Unit needs to be replaced. The motor is not field
serviceable. Do not attempt to repair. If NO, Inspect all wires and connections between the wall switch
and the motor. Repair connections as necessary. Recheck as in Step 1.
3.
If NO, Inspect all connections between battery and solenoid. Inspect 30A Auto-reset Circuit Breaker.
Recheck as above in Step 1.
NOTE: Since there are no field serviceable parts in the motor of the Power Unit, electrical troubleshooting
and service is limited to replacing only those components as previously outlined.
NOTE: Thorough inspection of wiring and connections is the only other electrical service that can be
performed.
