Power Unit; Assembling And Mounting The Valve Blocks; Hydraulic Hoses - Lippert Components Level-Up Manual

Power Unit

1 . The power unit mounting location was determined when the
coach was first inspected. Mount the power unit to the back
or side wall of the front compartment in the position you
previously determined using six (6) self tapping screws .
2. Install hose fittings into the power unit (Fig. 18). The two ports
are marked DN and UP . DN = Extend . UP = Retract .
Fittings installed in power unit

Assembling and Mounting the Valve Blocks

1 . Install two valve and coil assemblies in the Extend Valve block
(Fig . 19A & 19B) in the two center ports .
2. Install 4 straight JIC (Fig. 19F, G, H, I) adapters into the 4
ports across from the two valves you previously installed .
Install plugs (Fig . 19D) (removed from leveling jacks) into the
remaining ports .
3 . Install the Pressure Switch (Fig . 19C) in the center port of the
retract valve block. Install 3 straight JIC fittings (Fig. 19J, K, L)
into the 3 ports across from the pressure switch you previously
installed . Install plugs (Fig . 19E) (removed from leveling jacks)
into the remaining ports .
4 . Cut a piece of 3/4" thick plywood into a rectangle large enough
to mount both valve blocks .

5 . Mount the valve blocks to the plywood using 3" screws . Only
drive the screws far enough into the plywood to hold the valve
blocks in place . Do not pierce the back side of the plywood .
Mount the plywood to the back or side wall of the front
compartment next to the pump assembly using the screws
already holding the valve blocks in place .
NOTE: Do not overtighten mounting screws . Overtightening
may deform or damage the valve blocks causing them to
malfunction or leak .

Hydraulic Hoses

1. Connect the rear extend hoses (orange) to the JIC fitting in the
extend valve block directly opposite of the two valves, (Figs .
19G & 19H). Orientation is not critical at this point, the valve
coil wires can be switched to correct the function .
2. Connect the rear retract hose (black) to the JIC fitting in the
retract valve block directly across from the pressure switch,
(Fig. 19K).
3 . Make hoses to connect the power unit to the valve blocks . 3'
lengths should be sufficient; one (1) extend (orange) hose, and
one (1) retract (black) hose .
4 . Connect the extend hose to the extend (DN) side of the power
unit, and then to the JIC fitting on the extend valve block
closest to the power unit, (Fig . 19F) .
5 . Connect the retract hose to the retract (UP) side of the power
unit, and then to the JIC fitting on the retract valve block
closest to the power unit, (Fig . 19J) .
