Q

Describe the ADA doors on the ADA Vehicles

A

The ADA door is on a mechanically mounted hinge. A plunger pin is retracted from the door frame via a pull cable located near the RVs left side lap bar hub. The plunger pin is spring held and will extend once the pull cable is loose. This way the door is closed deliberately.

Q

How does the compensator work

A

Maximum flow is delivered until a specified system pressure is achieved (compensator setting). Then, the pump will only deliver the amount of flow necessary to maintain that setting.
