WARNING:
KEEP AWAY FROM THE WHEELS,
DO NOT CRAWL UNDER THE VEHICLE, KEEP A SAFE
DISTANCE IN FRONT AND REAR OF THE VEHICLE.
THE VEHICLE MAY DROP AND/OR MOVE FORWARD
OR BACKWARD WITHOUT WARNING AS THE VALVE
RELEASE IS OPERATED.
IMPORTANT: HWH recommends that all HWH room
extensions are fully retracted prior to performing
manual jack retraction procedures.
Use the manual valve release for retracting the jacks only
if the STORE feature on the HWH control panel will not
retract the jacks.
1. Locate your power unit-manifold assembly.
(The diagram below represents a typical Power Unit-
Manifold Assembly it may not be an exact match to yours).
NOTE: Multiple manifolds may be present on the
power unit. The upper most manifold should control
jack functions. (Valve styles and arrangements will vary)
2. Allow clearance for the vehicle to lower.
3. Using the diagram below identify the style
of your two center valves.
NOTE: As of APRIL 2002 a 1/4" Nut Driver has been
incorporated into the Breather Cap. Before using read
and understand the last page of this manual.

the T-Handle will turn harder. Make sure the valves have
been opened far enough to allow the jacks to retract.

release nut is located under a plastic plug that must be
removed to gain access. Open valve 1-1/2 to 2 full turns.

Slowly turn the manual valve releases counter clockwise
until the jacks start to retract.
5. Repeat the process by identifying then opening
the two outer valves, if applicable.

If no, notify the dealership where you purchased the vehicle
or had the leveling system installed or contact
HWH Corporation customer service.

IMPORTANT: Once the manual valve release is snug,
DO NOT tighten the manual valve release past this
point as internal damage may occur to the solenoid.
