Operating the Leveling System
Auto Leveling Operation
 Baseline Zero Point Calibration: “Baseline zero point” is the term used to de-
fine the point at which the motorhome interior floor is level in the “X” and “Y”
plains.
The base line zero point has been preset from the factory. If the coach is not level
following an attempt to auto level, you will need to reset the baseline zero point.
Setting the baseline zero point
1. Push and release the POWER keypad button to engage power. The LED next to the
POWER button should be RED when power is on.
2. Level the coach by deploying jacks manually (using the DOWN keypad button, extend
each jack until the coach is level) or by parking the coach on a level site.
3. Use a bubble level on a flat surface in the center of the coach as a reference.
4. Level the coach in both the “X” and “Y” plains (fore-aft and side to side).
5. Once level, turn the POWER off at the panel.
6. Depress and hold the AUTO-LEVEL keypad button.
7. Continue to hold the AUTO-LEVEL button and press and release the POWER button
and listen for a series of beeps.
8. After the panel has beeped 5 to 6 times, release the AUTO-LEVEL button (the keypad
will continue to beep as long as the AUTO-LEVEL button is held). The new baseline
zero point has been set and the panel will maintain this setting.
9. Press and release the ALL RETRACT button to retract the jacks to the stowed position.
Power On: Push and release the POWER button to engage power. The LED next to the
POWER button should be RED when power is on. You will need to have the ignition key in
the “off” position to extend the jacks. If you attempt to extend individual jacks by pressing
the ON button or all jacks with the AUTO-LEVEL button, you will hear a “deny” tone from
the keypad.
 Auto Level: Press the AUTO-LEVEL button and release. The system will send
out a continuous series of beeps, the “OPERATING” LED will flash RED to let
you know auto level is operating and will automatically level the coach. When
completed, the keypad will signal a successful level with a dual-level tone. The
keypad may be left on once level has been achieved. The keypad will enter “sleep
mode” after five minutes of inactivity.
 Retracting the Jacks: The Equalizer System provides the ability to retract the
jacks using the ALL RETRACT button or the UP button for each individual jack.
 All jacks will automatically retract and return to stowed position when the ALL
RETRACT button is pressed and released. The pump will run in retract mode for
60 seconds (or 90 seconds, depending on your specific system) to ensure the jacks
are fully stowed. You may allow the system to run for the entire programmed
time and stop automatically, or you may stop the ALL RETRACT by pressing any
button on the keypad.
NOTE: You do not need to have jacks deployed to set the baseline zero
point.
