PUMP RUN TIME
SYSTEM VARIATIONS FOR PUMP RUN TIME
Contact HWH corporation to get specific information about the system in this vehicle.
No matter what HWH system is on the vehicle, the pump should not be ran for more than four minutes
(3" motors) or six minutes (3.7" or 4.5" motors) without allowing the pump motor to cool for thirty minutes.
Continuous operation of the pump motor without allowing the motor to cool can damage the pump motor.
Some HWH systems are equipped with a lighted reset switch.
If the processor turns the pump off because the run time has
been exceeded, the light in the reset switch will turn on. The
With some systems, when the processor has turned the pump off because the run time has been exceeded, power
to the HWH system must be turned off and back on before the system will operate. With motorized vehicles, turn the
ignition off and back on. With non-motorized vehicles, turn the master power switch for the HWH system off and back

When operating some leveling systems manually or operating the room extensions, the pump will turn off and back

The HWH systems with a computer processor monitor the pump run time and will turn the pump off if the run time exceeds a
specified time. This time can vary with different systems. Due to available electronics or system design, the pump run time
programs will also vary. Leveling systems and room extensions that are not controlled by a system processor have no pump

For cold weather information see "COLD WEATHER OPERATIONS" below.
COLD WEATHER OPERATIONS
HWH leveling and room extension systems are designed to function in cold weather down to 0 degrees Fahrenheit. Below
freezing (32 degrees Fahrenheit) the jacks or rooms will operate slower than usual.
For operation in temperatures dropping below -20 degrees Fahrenheit, it is necessary that the system is equipped with oil
designed for extreme cold weather application such as a synthetic oil. (Contact HWH for recommendations.)
DO NOT run the pump motor continuously.
Continuous operation of the pump with slow moving jacks or rooms in cold weather, without allowing the pump motor to
cool will cause the pump motor to burn up and damage the pump assembly.

GENERAL INSTRUCTIONS
PREPARATION FOR TRAVEL
If parking on soft ground or asphalt paving, a wood block or
pad should be placed under each jack.
Any time a hydraulic leveling process is interrupted, it is
recommended to retract the jacks according to the JACK
RETRACTION Section and then restart the leveling process.
If the hand / auto brake is not set when the "AUTO LEVEL"
button is pressed, the "NOT IN PARK/BRAKE" light will
come on. When the "AUTO LEVEL" button is released the

the system needs to be serviced.
If the jacks cannot be retracted according to the JACK
RETRACTION Section, retract the jacks according to the
MANUAL JACK RETRACTION Section. The system
should then be checked.
Maintain adequate clearance in all directions for vehicle, room
extensions, awnings, doors, steps, etc. Vehicle may move in
any direction due to jacks extending or retracting, settling of
the jacks or the vehicle, equipment malfunction, etc..

With the vehicle level according to the bubble level, if there
are no yellow lights lit on the Touch Panel, the sensing unit is
properly adjusted. If there are yellow LEVEL lights lit on the
Touch Panel, manual adjustments to the Sensing Unit are
needed.
SENSING UNIT ACCURACY TOLERANCE
The sensing unit has an accuracy tolerance of ± 5.4 inches front to rear and

WHILE ADJUSTING THE SENSING UNIT. AFTER
ADJUSTING THE SENSING UNIT, BUMP THE SENSING
UNIT TO SEE THAT IT IS SETTLED TIGHT AGAINST ALL
THREE SCREW HEADS AND STILL INDICATES THAT
THE UNIT IS LEVEL.
Level the vehicle by placing a bubble level in the center of the
freezer floor or upon whichever surface within the vehicle that
is to be level. It is best if the level is placed close to the
mounting area of the sensing unit. Using the Leveling System
and the bubble level, ignoring the yellow LEVEL lights on the
Touch Panel, level the vehicle until the bubble is centered.
The ignition (motorized units) or master power switch (towable
units) must be on. Remove the "Adjusting Enhancement Cap".
DO NOT LOSE THIS CAP. There is a small pin beneath the
cap. Use a jumper wire with an alligator clip to apply a ground
to the pin. This will make the sensing unit very sensitive. The
yellow lights may "jump" around while adjusting the sensing unit.
Let the lights settle down after each adjustment. Small, gentle
turns will work best. Turn mounting screws 1 and 3 to adjust
the sensing unit. Turn screws as instructed to turn out all the
yellow LEDs. When all the LEDs are out, remove the jumper
wire and replace the adjusting enhancement cap. DO NOT
over tighten.
