Purging The System - Lippert Components Level-Up Manual

9 . Connect a ground wire from each of the valve coils to the
ground post on the dual polarity solenoid .
10 . Connect a ground wire from the ground post on the dual
polarity solenoid, to a grounding bolt on the frame of the
coach . This will ground the entire system .
NOTE: These grounding wires are installer supplied .
11 . Connect a power wire to the center post of the dual polarity
solenoid . Mount an 80 amp circuit breaker to the back wall
of the front compartment . Connect the power wire from the
dual polarity solenoid to the AUX end of the 80 amp breaker .
Connect another power wire to the BAT side of the 80 amp
breaker and run that to the battery or buss breaker battery
hookup .
NOTE: Shore power (plugged in) does not operate the Level Up
System as shore power is alternating current . The unit must be
connected to a 12V battery, the correct source of direct current
for the power unit .

Purging the System

NOTE: Refer to the Plumbing Diagram (Page 18, Fig . 41)
throughout these instructions .
1. Fill the pump reservoir with recommended fluid to about 3/4 full.
Make sure the unit is supported at the hitch pin, and remove
the corner supports . Be sure any stabilizer jacks have been
retracted .
2 . Disconnect hoses A and B from the lead landing gear .
3 . Remove hoses C and D from the valve blocks and connect C
to where A was removed and D to where B was removed from
the lead landing gear . You have now connected the power unit
directly to the lead landing gear . This will allow you to purge air
from the two landing gear jacks without pushing the air into the
leveling jacks .
4 . Manually extend the landing gears until they just touch the
ground . Do not try to lift the unit at this point . Manually retract
the jacks fully .

5. The fluid in the reservoir will now be full of air and there will be
foam rising to the top of the fluid. Leave the fill cap off of the
reservoir to allow the air to escape from the fluid. Do not try
to activate the system again until the fluid in the reservoir has
returned to its normal condition .
6 . Manually extend the landing gear again, this time to their full
stroke .
7 . With the landing gear fully extended, remove the retract hose
from the landing gear and reattach it to the valve block .
Reattach the retract hose you removed in Step 2 to the landing
gear .
8 . Fully retract the landing gear and then remove the extend
hose from the lead landing gear and reattach it to the valve
block . Reattach the extend hose you removed in Step 2 to the
landing gear .
9 . Manually extend the landing gear until they just touch the
ground . Do not try to lift the unit at this point . Repeat this
process for the left and right leveling jacks . Again, do not try to
lift the vehicle .
10. Add fluid to the reservoir until it is half full.
11 . Scroll up on the interface until you see "AUTO RETRACT
Press Enter to begin . " Press Enter .
12 . This will retract all the jacks and landing gears . You will hear
many popping sounds as air is being flushed from the jacks.
13. The display should read "READY: JACKS UP" at this point.
14. The fluid in the reservoir will now be full of air. Leave the fill
cap off of the reservoir to allow the air to escape from the fluid.
15 . While that is happening, you can reattach the underbelly to
the frame, being sure not to pinch or screw through any of the
hydraulic hoses .
16. Once the fluid has returned to its normal color (red), add more
fluid to the reservoir until the level is about 1/2" below the fill
cap .
