The Liberty Coach has 4 Cruise Air split units. The condensor and evaporating coils are located in the bays. (2 in the center of bay #2, 2- in the front behind the bumper.) The bedroom has 1 fan coil and contol, the Galley & living have 2 fan coils & contols and the the driver and passenger have 1 fancoil and control. They run off of Shore power and/or Generator power.
Because the condensor coil is beneath the floor , it recieves its air from below the Coach. This can be a problem if the outside air temp is too hot and the road is hot. It will shut down the A/C units.
These same units can also be used for heating the Coach.
