Roof Air Conditioning
The 13,500 BTU air conditioning system is 120 VAC powered and thermostatically
controlled. In addition to its cooling power, you can also use it as a forceful circulation
fan. The airflow is ducted through registers on the ceiling.
The system requires little maintenance. One filter protects the cooling coils from debris
and should be changed regularly. To change the filter, remove the shroud on the bottom of
the intake vent, insert the new filter and replace the shroud. Do not run the unit without
filters. Check the manufacturer's manual for maintenance details and specifications.

Attic Fan
One of the most overlooked features in your coach is also one of the most important for
keeping it comfortable. Powered by the 12 VDC house batteries, the attic fan is essential
for controlling temperature, humidity and odors. Properly used, it can reduce your
reliance on heating and air conditioning and save considerable energy in the process.
You should always run the attic fan while cooking, bathing, or sleeping to reduce humidity.
It will also assist in exhausting odors from the coach.
It should be run while the furnace is on to control condensation. The fan uses much less
power than the air conditioner and should be used to cool the coach. In addition, it can boost
the effectiveness of your air conditioning unit by removing warm air from the ceiling.
You should also use the attic fan when heating your coach in cold weather. The coach is
likely to be closed up, causing moisture to build. Moisture and high humidity can damage
the wood interior and furniture in the coach. As a result, it is very important to keep the
humidity level low.
