These air conditioners were designed to operate from a 115
VAC, 60 HZ, 1 Phase power supply. Anytime an air
conditioner is not operating properly, the power supply should
be examined by a qualified technician to verify that the air
conditioner is receiving the proper power supply.
The ability of the air conditioner to maintain the desired inside
temperature depends on the heat gain of the recreational
vehicle.
The size of the vehicle, amount of window area, amount of
insulation, direct exposure to the sun, outside temperature and
the number of people in the recreational vehicle may increase
the heat gain to such an extent that the capacity of the air
conditioner is exceeded.
As a general rule, air entering the air conditioner will be
cooled about 15 to 20 degrees, depending on the outside
temperature and humidity conditions.
For example, if the air entering the return air grilles in the air
conditioner is 80 degrees F., the air leaving the discharge
grilles in the air conditioner will be 60 to 65 degrees F.
As long as this temperature difference is being maintained
between the return air and discharge air, the air conditioner is
operating at its capacity. If the desired inside temperature
(normally 80 degrees F) cannot be maintained, then the heat
gain of the RV is too great for the capacity of the air
conditioner.
If your RV air conditioner is operated from the control panel
located in the ceiling assembly, then there are three controls
on the ceiling assembly that help you control the air
conditioner. They are as follows:
A. The Selector Switch – The selector switch determines
which mode of operation the air conditioner will be
in. By rotating the selector switch, the operator can
obtain any system function desired. System
functions vary depending upon options of both the
roof top unit and ceiling assembly. Figure 1 shows
selector switch location and lists all available
functions by model.

Parking the vehicle in a shaded area, keeping windows and
doors shut and avoiding the use of heat producing appliances
in the vehicle will help to reduce the heat gain. When
possible, the addition of insulation and tinted glass (especially
in uninsulated vans) should be considered.
The optional heating assembly is intended to take the chill
out of the indoor air when the air is a few degrees too cool
for comfort. The heating assembly is an effective "chill
chaser". It is not a substitute for a furnace.
R410A Roof Top Air Conditioners
High Pressure Switch Lockout Circuit
Air conditioners and heat pumps using R410A refrigerant may
utilize a factory installed High Pressure Switch Safety Circuit.
In the event of an abnormal condition (failure of fan motor,
dirty condenser coil, dirty filters), the high pressure switch
will prevent the compressor from continuing to run. Once the
high pressure switch has tripped, this safety circuit will "Lock
Out" the compressor preventing it from trying to restart or run
until the 115 VAC supply power has been turned off and then
back on to reset the High Pressure Switch Safety Circuit. If
repeated trips of the high pressure switch lock out occur, then
you must have the unit serviced by a qualified technician.
The "Operation" section explains the operational
characteristics of each mode of operation.
B. The Thermostat (temperature control) – In the
cooling mode, the thermostat regulates the "ON" and
"OFF" temperature setting at which the compressor
will operate.
For "Heat/Cool models, the thermostat also controls
the "ON" and "OFF" temperature settings of the
heater assembly (See Figure 1).
