CONTROL IDENTIFICATION
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 three 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
DO NOT continue without allowing the pump motor to cool for thirty minutes.
When operating some leveling systems manually or operating the room extensions, the pump will turn off and back
on while pushing the control button when the pump run time has been exceeded.

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
run time protection.

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, retract
the jacks according to the JACK RETRACTION Section and
then restart the leveling process.
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.

APEX SYSTEM
Refer to the vehicle manufacturer for leveling system
operating instructions.
AUTO LEVEL SEQUENCE: During the automatic leveling
sequence, after the system has extended the appropriate
jacks to level the vehicle, the system will then stabilize the
vehicle. Stabilizing the vehicle is accomplished by extending
any jacks to the ground that were not used to level the
vehicle. This is done by monitoring a pressure switch on
each jack. Any jack used to stabilize the vehicle will lift the
vehicle approximately one (1) inch. This "bumps" the vehicle
up slightly when stabilizing.

NOTE: When traveling thermal expansion may cause
a jack to extend slightly. When the "AUTO STORE"
button has been used to retract the jacks, the system
will automatically retract any jack that extends due to
thermal expansion.
IMPORTANT: If a red warning light and buzzer come on
while traveling, the jacks should be checked as soon as
a safe parking location is found.
NOTE: When the jacks are stored with the ignition in
the ON position, the warning buzzer will sound until
the jacks have retracted to the STORE position. If
desired, the jacks can be stored with the ignition key
in the accessory position. This will eliminate the
warning buzzer while the jacks are retracting.
IMPORTANT: If power to the system is interrupted
after starting a store procedure, the store procedure
should be reinitiated and the jacks should be
completely retracted.

AUXILIARY PUMP OPERATION
The vehicle is equipped with an auxiliary hydraulic pump for
the leveling system, room extensions and the Joey beds.
The hydraulic pump assembly is in the passenger side front
compartment. There are two toggle switches; one labeled
"PRIMARY / AUXILIARY, the other is "MANUAL RUN".
The MANUAL RUN switch is a momentary switch that can
be used to run either the primary or auxiliary pump from the
pump compartment.
IMPORTANT: DO NOT RUN THE PUMP FOR MORE THAN
10 SECONDS IF THE JACKS, ROOMS OR JOEY BEDS
ARE NOT MOVING.
The PRIMARY / AUXILIARY switch chooses which pump is
being used. The switch should remain in the PRIMARY
position unless the primary pump is not working.
