IMPORTANT
It is not the policy of Airxcel, Inc. to size generators for
application in Recreational Vehicles. However, when sizing
generators, the total electrical power consumption in Watts
must be determined and taken into consideration, such as:
A.
Maximum running watts of the air conditioner at
A.R.I. maximum operating conditions (See
specifications).
B.
Power consumption of electronic ovens, electric
toasters, electric coffeemakers, television sets,
refrigerators, lights, etc.
C.
Generators do lose capacity under the following
conditions: (1) Altitude increases above sea level,
(2) Temperature increases above certain outdoor
design temperatures, (3) Lack of maintenance.
The size of recreational vehicle air conditioners is generally
limited to about 13,500 BTUH (approximately one ton) of
cooling.
This is due to the limited electrical power normally available
in most trailer parks and/or economic limitations on the use of
generators with enough capacity to handle large air
conditioners.
If more than 1 ton of cooling is desired, then the use of two air
conditioners is recommended.
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

I. GENERAL INFORMATION
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 the 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.
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.
R410 Roof Top Air Conditioners
High Pressure Switch Lockout Circuit
Air conditioners and heat pumps using R410A refrigerant
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.
