GENERAL HWH® ENVIRONMENTAL AIR SEAL INFORMATION

 

  Air seals are made of an inflatable seal that goes around the perimeter of a slide-out to provide a superior seal against the outside elements.

 

  Air is forced into the seal after the slide-out has been fully extended or retracted.

 

  Before the slide-out can be extended or retracted the air seal has to be deflated.

 

  HWH® air seals are pressurized by their own small air compressor and tank.

 

  With HWH® slide-out systems, the slide-out control key has to be on to evacuate air from the seal and operate the slide-out.

 

  After a timed delay, the slide-out panel will indicate the slide-out is ready to operate.

 

  The slide-out will not operate until the panel indicates the air seal is deflated and it is safe to operate the slide-out without damaging the air seal.

 

  The air seal will inflate when the slide-out control key switch is turned off or if the ignition switch is slide-out off.
