1.1 INTRODUCTION
This manual contains service instructions and electrical
data for the AirV, Carrier Transport Air Conditioning's
Recreational Vehicle air conditioning unit.
The AirV units are two piece systems, consisting of the
Upper Unit and the Ceiling unit. The Upper Unit contains
the refrigeration system while the Ceiling Unit contains
the controls and vents. The Ceiling Units are available in
a free--blow or ducted configuration.
The free--blow units (see Figure 1--2) deliver air to the
vehicle by means of front and rear end vents and one
downward vent (air shower). The vents may all be
opened or closed to direct air as desired. The front and
rear vents are fitted with motorized dampers that
oscillates to produce an "air--sweep" effect. These units
may be fitted with optional electric heat.
The ducted units (see Figure 1--5 and Figure 1--10)
deliver air through ducting built in the vehicle ceiling.
These units are fitted with a 12 VDC microprocessor
control system, a display panel (PCB display) and a
remote controller. These units may be wired to provide
thermostatic control of the vehicle furnace.
Carrier's AirV air conditioning models include cooling
only units, heating/cooling units, and heat pump units.
The cooling only units are available with free blow or
ducted air delivery. Cooling units with heat strips are
available for free blow only.
Operation of the AirV units is controlled automatically by
the
temperature
controller
maintains the vehicle's interior temperature at the
desired set point. Free Blow, cool--only units are
available with a wall mounted thermostat.
Table 1--1 lists Upper Unit AirV model numbers and
descriptions. Table 1--2 lists Ceiling Unit model
numbers and descriptions. Table 1--3 lists additional
support manuals that are available.
1.2 SERIAL NUMBER IDENTIFICATION
Separate part numbers and serial numbers are provided
for the upper and lower unit assemblies The numbers
may be found on plates readable from inside the vehicle,
See Figure 1--11 or Figure 1--12.
The first two numbers of the serial number, see
Figure 3--23, is the week the unit was manufactured.
For example, 01 would designate the first week of the
year and 52 would designate the last week of the year.
The third and fourth numbers designate the year in
which the unit was manufactured. For example, 99
