My coach has the Jun-Air 110 volt compressor located in the generator compartment. It seldom runs and is exceedingly quiet. It shuts off at 105 lbs. Attached are two photos showing the air pressure switch, with and without the cover. Nothing is bolted to the floor. I note that there are two sets of wires going to the two terminals in the air pressure switch. Obviously, one is the 110 volt source from the on/off switch located in the galley. The other set comes from the wiring harness with no coil in sight, and may be the bypass for the HWH system. I am hesitant to disconnect them know knowing exactly what their function is. Wonder if anyone has the wiring schematic for the HWH system.
