CONTROL IDENTIFICATION

PUMP RUN TIME

PUMP RUN TIME

Pump motors used with HWH leveling systems and room extension systems come in 3 different diameters; 3", 3.7" and 4.5".

Contact the vehicle manufacturer or HWH for help with identifying the motor size.

It is important that any time the pump runs for more than four minutes with a 3" motor; or six minutes with a 3.7" or 4.5" motor that the motor is allowed to cool for thirty minutes before continuing. Continuous operation of the pump motor without allowing the motor to cool can damage the motor.

For cold weather information see "COLD WEATHER OPERATIONS" below.

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.

DO NOT run the pump more than four or six minutes without allowing the pump motor to cool for thirty minutes.

SYSTEM VARIATIONS FOR PUMP RUN TIME

Some systems with rooms run the rooms separate from the system processor. These systems do not monitor pump run time when operating the rooms.

DO NOT run the pump more than four or six minutes without allowing the pump motor to cool for thirty minutes.

Some systems can be turned back on immediately after the processor turns the pump off.

back on or run the pump without allowing the pump motor to cool for thirty minutes.

DO NOT turn the system

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.

DO NOT continue without allowing the pump motor to cool for thirty minutes.

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 on.

DO NOT continue without allowing the pump motor to cool for thirty minutes.

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 system will not operate until the reset switch is pushed.

DO NOT continue without allowing the pump motor to cool for thirty minutes.

LIGHTED RESET SWITCH

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.

Contact HWH corporation to get specific information about the system in this vehicle.

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.

It is important that any time the pump runs for more than four minutes with a 3" motor; or six minutes with a 3.7" or 4.5" motor that the motor is allowed to cool for thirty minutes before continuing. Continuous operation of the pump motor without allowing the motor to cool can damage the motor.

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.

"OFF" at any time to stop the operation of the system.

PREPARATION FOR TRAVEL

IMPORTANT: Before traveling, the red jack warning lights must be off, the "TRAVEL MODE" light must be on and the vehicle should be at the proper height for travel.

If lights are not correct for travel, retract jack as described in the JACK RETRACTION Section.

If the jacks are retracted but a red "WARNING" light is lit the system needs to be serviced.

HAZARD. DO NOT RELY SOLELY UPON WARNING

LIGHTS. IT IS THE OPERATOR’S RESPONSIBILITY

TO CHECK THAT ALL JACKS ARE FULLY RETRACTED

INTO THE STORE/TRAVEL POSITION AND THE

VEHICLE IS AT THE PROPER RIDE HEIGHT FOR

TRAVELING. CONTACT MANUFACTURER TECHNICAL

SERVICE BEFORE MOVING A VEHICLE THAT IS NOT

AT PROPER TRAVEL HEIGHT.

Any room extension, step or generator slide should be fully retracted before traveling.

WARNING:

DO NOT MOVE THE VEHICLE WHILE

THE LEVELING JACKS ARE STILL IN CONTACT WITH

THE GROUND OR IN THE EXTEND POSITION. THIS

VEHICLE IS EQUIPPED WITH STRAIGHT-ACTING JACKS.

MOVING THE VEHICLE WITH THE LEVELING JACKS

EXTENDED CAN CAUSE SEVERE DAMAGE TO THE

JACKS AND OR THE VEHICLE AND CREATE A DRIVING

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.

NOTE: If the vehicle is parked or stored with the jacks extended for an extended period of time and the jacks fail to retract completely, extend the jacks back down to the ground then retract the jacks again.

ROOM EXTENSION PROCEDURES

IMPORTANT: If the vehicle is equipped with a room extension read this section carefully.

Refer to the vehicle owners manual for proper operation of room extensions.

If the vehicle is equipped with kick-down jacks, the wheels

MUST be blocked securely. It is recommended to complete the Leveling Procedure before operating room extensions.

It is recommended to retract room extensions before retracting jacks.

IMPORTANT: Do not use a room extension support when the vehicle is supported by the leveling system.

OPERATING PROCEDURES

725 SERIES LEVELING SYSTEM

AUTOMATIC HYDRAULIC LEVELING

1. Place transmission in the recommended position for parking the vehicle and set parking brake. Turn the coach engine off. Turn the ignition to the "ACCESSORY" position.

2. At this time, the operator may want to check the jacks and place a pad under each jack if the ground will not support the vehicle.

NOTE: If the vehicle has an air suspension, running the vehicle engine during leveling can cause erratic operation and inhibit proper leveling of the vehicle.

WARNING:

PRIOR TO PUSHING THE "AUTO LEVEL"

BUTTON THE OPERATOR MUST BE SURE THAT ALL

PERSONS AND OBJECTS ARE CLEAR OF THE VEHICLE.

The sequence starts with the right rear jack. If the pressure switch is not on, the system will extend the jack as necessary.

If the switch is on (or when it comes on) the system will check the left rear jack pressure switch, extending the jack if necessary

If the left rear switch is on (or when it comes on), the system will recheck the right rear (extending if necessary) then recheck the left rear (extending if necessary). After checking and rechecking both rear jacks, the system then checks the front jacks. The system checks both front jacks at the same time.

If either pressure switch is not on, the system will turn the pump on and open the valves for both front jacks. When both front pressure switches are on, the system turns the pump and front valves off.

NOTE: If the vehicle is equipped with an air suspension and a manual suspension dump, the suspension air should be exhausted at this time. Refer to the vehicle manufacturer for operating instructions.

If at this time a yellow level light is on, the system will automatically repeat the leveling sequence. The repeat sequence will only happen if a yellow level light is on at the end of the initial leveling and stabilizing sequence.

If a yellow level light is still on after the repeat sequence, the system will turn off, leaving the level light on.

3. Press the "AUTO LEVEL" button one time.

The AUTO LEVEL light will start to flash.

The leveling process will begin.

Pairs of jacks will extend according to lit yellow level lights.

The system will level side to side if needed before leveling front to rear.

A red jack down light will come on as it’s jack extends approximately 1 inch. If any red jack down warning light is on, the TRAVEL MODE light will be off and the master warning light will be on.

The slight lift experienced during the stabilizing procedure normally is not sufficient to cause a level issue for the motor home. However, a feature of the single step leveling system is the manual leveling buttons will function anytime the ignition is in the ON or ACC. position and the park brake is set. If desired, the operator can use the UP ARROWS

(extend jacks) that correspond to any lit yellow level indicator light to "bump" the vehicle up slightly to turn that yellow indicator light off.

IMPORTANT: During the Automatic Leveling procedures, pushing the "AUTO LEVEL",

"AUTO STORE" or the "CANCEL" button on the HWH touch panel will stop the automatic leveling function.

After all yellow level lights are out, the system will stabilize the vehicle.

Stabilize sequence information:

The stabilize sequence is part of the auto level sequence. Each jack has a pressure switch. The switch will turn on when the jack extends to the ground and lifts the vehicle slightly. Jacks that have lifted the vehicle for leveling should have pressure switches that are on.

EXCESS SLOPE SITUATION: In the event the jacks are unable to level the coach, the "EXCESS SLOPE" light will come on. Excess slope is one or more jacks fully extending without turning the yellow level light out. The system will not stabilize the vehicle if the "EXCESS SLOPE" light comes on.

One or more jacks may not be extended. The system will shut off leaving the "EXCESS SLOPE" light on. The

"EXCESS SLOPE" light will remain on if the ignition is in the

"ON" or "ACC" position, until the jacks have been fully retracted turning the red warning lights out. Push the

"STORE" button to retract the jacks. Move the vehicle to a more level position or level the vehicle as close as possible according to the MANUAL HYDRAULIC OPERATION section.

4. Turn the ignition switch to the "OFF" position.

The stabilize procedure is a specific sequence where the computer checks the jack pressure switches. If the switch is on, the jack is stabilizing the vehicle. If the switch is not on, the computer turns the pump and valve on for that jack until the pressure switch turns on.

MANUAL ROOM RETRACTION PROCEDURES - SPLINED TORSION SHAFT

PAGE 1 OF 2

In the event of a hydraulic failure, including the hand pump, if so equipped, the room and floor can be manually retracted.

IMPORTANT: KEEP PEOPLE CLEAR OF THE ROOM

WHEN MANUALLY RETRACTING THE ROOM. MAKE

SURE THERE ARE NO OBJECTS SUCH AS CARPET,

CHAIRS, ETC. BLOCKING OR INTERFERING WITH

THE MOVEMENT OF THE FLOOR OR ROOM.

To manually retract room, first the floor must be completely lowered. The floor raise / lower mechanism must be accessed to accomplish this. An area closest to the floor lift cylinder is the best area to use. A spline wrench which will be needed to turn the main mechanism spline shaft is wire tied to the main floor lift cylinder.

1. Determine which synchronizing cylinder controls the room.

Open both valves by moving the valve release cam to the open position as shown in the following diagram.

2. Locate the pressure control valve. This valve must be opened to lower the floor. the pressure control valve is wire tied to the synchronizing cylinder or mounted directly to the main floor lift cylinder. (See the hydraulic diagram or contact

HWH Corporation) The end of the valve has a 1/4" release nut. Use a 1/4" nut driver to turn the nut 4 & 1/2" turns counterclockwise. DO NOT turn the nut more than 5 turns or damage to the valve can occur.

3. Access the splined shaft as close to the main floor lift cylinder as possible. (See floor lift mechanism diagram.)

4. Use the spline wrench provided, to rotate the splined shaft in the direction shown in the floor lift mechanism diagram. The floor lift cylinder should extend as the floor lowers to the store position.

5. When the floor is completely lowered, the room can be retracted. Proceed to page 2 for manual room retraction instructions.

NOTE: The floor should not be raised hydraulically or manually until the system has been serviced.

4. Move to the other room extension mechanism, rotate the threaded rod clockwise 12 complete turns.

5. Return to the first room extension mechanism and rotate the threaded rod clockwise 12 complete turns.

6. Repeat steps 4 and 5 alternating from mechanism to mechanism rotating each threaded rod 12 complete turns until room is sealed. (DO NOT exceed 15 ft.lbs) Make sure the room does not bind.

IMPORTANT: If at any stage something is not understood or if the room begins to bind DO NOT force the room, contact HWH Customer Service for assistance

1-800-321-3494.

NOTE: Leave the solenoid valves open and the threaded rods in place until the room has been serviced.

IMPORTANT: DO NOT EXTEND THE ROOM UNTIL THE

ROOM HAS BEEN SERVICED. ANY SOLENOID VALVES

LEFT OPEN SHOULD BE CLOSED AND THE THREADED

RODS SHOULD BE COMPLETELY REMOVED.

NOTE: If there is not enough room to remove both threaded rods completely, alternate backing the threaded rods out and slightly extending the room.

Be careful to not extend the room so far that the threaded rods impact the coach wall or the mechanism.

NOTE: Each hydraulic function requires a pair of solenoid valves one each for the extend and retract procedures. The number of functions and the items controlled by each pair of solenoid valves will very for each system. The diagrams shown on this page represent a (3) function system of (2) jacks and

(1) room as indicated by the labels shown in FIG 1. Use the labels specific to your system when following these procedures.

Room control solenoid valves may be located at the synchronizing cylinder, not on the pump manifold.

The auxiliary hand pump can be used to extend or retract the landing gear, jacks or room extensions anytime the pump will not function.

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

NOTE: The hand pump will swivel to any position which will ease the operation of the hand pump.

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

FIG 1

NOTE: If a room cannot be retracted using the auxiliary hand pump, see "MANUAL ROOM

RETRACTION PROCEDURES".

WARNING:

THE VEHICLE SHOULD BE

SUPPORTED BY AUXILIARY STANDS OR SECURELY

HITCHED TO THE TOW VEHICLE BEFORE OPENING

ANY VALVES.

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

vehicle if only one solenoid valve is open.

IMPORTANT: FOLLOW THE "SET UP" AND

"PREPARATION FOR TRAVEL" PROCEDURES

WHEN USING THE AUXILIARY HAND PUMP.

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

IMPORTANT: ONLY MOVE THE RELEASE CAM

IN THE DIRECTION SHOWN. MOVING THE CAM

IN THE OPPOSITE DIRECTION CAN DAMAGE

THE VALVES.

MAINTENANCE

OIL LEVEL

It is important that the four leveling units are fully retracted before checking the hydraulic oil level. The room should be extended to check the oil level. To check the oil supply, remove the breather cap from the top of the hydraulic oil reservoir. The oil level should be approximately one inch below the top of the reservoir when adequately filled.

FLUID: HWH Specialty Hydraulic Oil is recommended. In an emergency Dexron automatic transmission fluid can be used.

NOTE:

Dexron automatic transmission fluid contains red dye and can cause staining should a leak occur. DO NOT USE brake fluid or hydraulic jack fluid. Use of these can damage seals.

UNUSUAL CONDITIONS

In general, to insure the smooth operation of the leveling system, it is a good idea to occasionally check the individual leveling units to prevent problems. This is especially true

Do not move the trailer while the leveling units are still in contact with the ground. Visually check to see if the leveling units have returned to the STORE/TRAVEL position before

If driving conditions are unusually muddy, the units may become caked or clogged with mud. This condition may hamper the proper operation of the leveling system. This problem may be prevented or remedied by cleaning off each

NOTE:

All major components of the system can be replaced with rebuilt units or can be sent to HWH CORPORATION to be rebuilt, when the system is out of warranty. leveling unit if they become excessively muddy.

In wet or icy weather leveling units may become encrusted with ice. This may cause the leveling system to function improperly. To eliminate this problem, periodically check the leveling units and break loose any ice which may be causing improper operation.

NOT IN PARK/BRAKE CHECK

WARNING:

WHEN MAKING THIS CHECK, BLOCK

THE COACH WHEELS SECURELY SO THE COACH

CANNOT ROLL FORWARD OR BACKWARD.

If any of the above checks or inspections reveal a problem or if there are other problems or questions, consult a qualified RV repair center, your vehicle or coach manufacturer, or HWH CORPORATION for service or repair.

Apply the brake so the coach cannot roll. Turn the ignition to the "ACC" or "ON" position. Release the parking brake.

Push the "AUTO LEVEL" button. The "NOT IN PARK/

BRAKE" indicator light should come on while the "AUTO

LEVEL" button is pushed. Release the "AUTO LEVEL" button and set the park brake. The leveling system should now function.

WINTER WEATHER DRIVING

Anti-icing / deicing agents when splashed on your vehicle, continue to absorb moisture from the air even after they have dried. This can facilitate corrosion of metallic components, such as HWH jacks.

To help reduce the corrosion of jacks after exposure to antiicing / deicing agents, thoroughly wash jacks with warm soapy water.

INSTRUCTION SHEET

SENSING UNIT MAINTENANCE/SERVICE

REMOTE MOUNTED "POTTED" ELECTRONIC SENSING UNIT

SENSING UNIT ACCURACY TOLERANCE

The sensing unit has an accuracy tolerance of ± 5.4 inches front to rear and

± 1 inch side to side on a 36 foot vehicle. Typical leveling results will be better.

SENSING UNIT ADJUSTMENT / WITH ADJUSTING ENHANCEMENT

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.

Move the vehicle to an unlevel position and level the vehicle according to the yellow level sensing lights on the touch panel. Readjust if necessary.

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.

IMPORTANT: THE SENSING UNIT MOUNTING SPRINGS

SHOULD BE COMPRESSED ABOUT 1/2 THEIR FREE

LENGTH. SCREW NUMBER 2 SHOULD NOT BE TURNED

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.

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.

NOTE: If opposing LED’s are lit, there is a problem with the Sensing Unit.

If LED (A) is lit: Tighten adjustment screw number 1 until the LED is off.

If LED (C) is lit: Loosen adjustment screw number 1 until the LED is off.

If LED (B) is lit: Loosen adjustment screw number 3 until the LED is off.

If LED (D) is lit: Tighten adjustment screw number 3 until the LED is off.
