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.

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.

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 tocool will cause the pump motor to burn up and damage the pump assembly.

WARNING: THE VEHICLE SHOULD BE

IMPORTANT: FOLLOW THE "SET UP" AND"PREPARATION FOR TRAVEL" PROCEDURESWHEN USING THE AUXILIARY HAND PUMP.

AUXILIARYHAND PUMPHANDLE

The auxiliary hand pump is a two stage pump that will produceenough pressure to extend the landing gear and lift the vehicleas well as retract the landing gear. When operating the auxiliarypump to lift the vehicle or when the jacks are fully retracted, thepump handle will seem to "snap" as the pump goes to thesecond stage. The pumping action will be easier at first as thesecond stage starts to create more pressure.

To operate the auxiliary hand pump, open the appropriate solenoid valve. Insert the hand pump handle into the handlereceptacle and move the handle in an up and down motion.

The auxiliary hand pump may work easier if only onevalve is open at a time. Be careful to not twist thevehicle if only one solenoid valve is open.

It is recommended to operate the auxiliary handpump occasionally to check it’s operation.
