HEATING & AIR CONDITIONING
NOTICE
The air conditioning system is the major consumption device of electrical power in the
motorhome. When this system is being used in an RV park, cumulative use of these
air-conditioning systems by the resident vehicles can create a bigger demand for elec-
trical power than is actually available. Accordingly, at times a “brown-out” condition may
arise. This is when the AC voltage normally available drops to a lesser value (e.g., 10-20%
below normal or more).
“Brown-out” conditions cause appliances to draw greater currents to make up for the
reduced voltage; thereby causing circuit breakers to trip or fuses to blow. Under such
conditions, your own motorhome is not at fault; simply reset your breakers and/or re-
place your fuses. Should such conditions continue, you may wish to reduce the electrical
load (in this case, turn “off” the air conditioning system for awhile) or start the electrical
generator.
The factory-installed air-conditioning system is designed for 120 VAC power supplied either from the
external power cord or from the generator. For the best cooling scenarios, park the motorhome in a
shady location whenever possible and close drapes on those windows exposed to direct sunlight.
The air-conditioned, cooled air is emitted through the vents which are located in the roof throughout
the entire coach along the passenger side. The return air vents run parallel, front to back, on the ceiling
along the driver’s side of the coach. The return vents are similar to the air conditioning vents, but they
contain foam filters that keep dust from flowing back through the air conditioning system. The return
filters can be easily removed and cleaned with warm water and and a mild cleaning solution. To remove
the filter, simply pull the vent down and lift the filter from inside the opening.
