How does the HWH air leveling system work?

HWH controls the side air bags and the front or rear air bags of the vehicle to obtain a level position. Leveling the vehicle side to side should always be done first before leveling the vehicle from front to rear. Older air leveling systems and Prevosts use a three- point air leveling system.

How does leveling work in an air bag?

With either type of system, leveling is accomplished by isolating the air bags from the height control equipment. Air is then released from the air bags to lower the vehicle (or) air is added to the air bags to raise the vehicle.

How do I Turn Off the air leveling system?

Press it for 10 seconds. Then check if all the yellow lights are on, if not then wait for a bit. And if yes then press the air button twice. This activates the system. As soon as you press the button, you’ll hear the sound of air flowing. And when it’s balanced, the sound will stop on its own. Then you can stop pressing this button.

How is ride height determined in HWH system?

HWH air leveling system, we will refer to these as Height Control Valves. These valves maintain a specific distance between the vehicle frame and axles. This distance is determined and set by the vehicle manufacturer. We call this “Ride Height”. The ride height is not controlled by the HWH leveling system. a regulated air supply.

What kind of air suspension does HWH provide?

HWH provides (2) basic types of air leveling systems. In one, HWH supplies a series of air solenoid manifolds to control the air suspension for leveling. The other type of leveling system is for Prevost busses. For the Prevost, HWH supplies only the electronics to control the Prevost air solenoid valves. R R R with the exception of the Prevost.

What kind of leveling system does a Winnebago Brave have?

Have a 2004 Winnebago Brave with the HWH 325 series Leveling System. While driving the yellow ‘Jacks Down’ indicator light turned on and buzzer sounded, pulled over and found the LR jack was down about 1/4 inch with the round RF jack indicator on the keypad was ‘red’.

Why is my HWH 200 not leveling properly?

As in all high-pressure hydraulic systems, maintaining the proper oil level in the reservoir of the HWH 200 prevents air from entering the system. Failure of the jacks to fully extend is the primary symptom of insufficient hydraulic oil and air in the system. Retract all four jacks fully.

How to check the fluid reservoir for HWH leveling?

Proper oil level should appear in the range between the two scribed lines on the dipstick. Add HWH Specialty hydraulic oil or Dexron-style automatic transmission fluid to the reservoir if necessary.

What do you need to know about HWH systems?

HWH SYSTEMS TEXT BOOK. HWH air leveling uses the vehicle’s air suspension to level the vehicle instead of using hydraulic cylinders. Air leveling can only be used on vehicles with a full active air suspension. A full active air suspension uses air springs (air bags) on the front and rear axles.

Where are the jacks on a HWH-RV?

In the manual mode, the jacks are controlled by the UP and DOWN arrow buttons on the right hand side of the touch panel. The UP arrows extend jack pairs and the DOWN arrows retract jack pairs. If the vehicle is equipped with an air suspension, the air must be exhausted from the suspension before leveling the vehicle.

What are the components of a HWH system?
