SAFETY SUMMARY

GENERAL SAFETY NOTICES

The following general safety notices supplement the specific warnings and cautionsappearing elsewhere in
this manual. They are recommended precautions that must be understood and applied during operation and
maintenanceoftheequipmentcoveredherein.Thegeneralsafety notices arepresentedinthefollowingthree
sections labeled: First Aid, Operating Precautions and Maintenance Precautions. A listing of the specific
warnings and cautions appearing elsewhere in the manual follows the general safety notices.

FIRST AID

An injury, no matter how slight, should never go unattended. Always obtain first aid or medical attention
immediately.

OPERATING PRECAUTIONS

Always wear safety glasses.
Keep hands clear of the evaporator blower and condenser fan.
No work should be performed on the unit until all circuit breakers and start--stop switches are turned off, and

power supply is disconnected.
Always work in pairs. Never work alone.
In case of severe vibration or unusual noise, stop the unit and investigate.

MAINTENANCE PRECAUTIONS

Beware of unannounced starting of the evaporator blower & condenser fan. Do not remove the ceiling grill
assembly or the upper unit coverassembly beforeturningthe power off, and disconnecting the power supply.
Before disconnecting, discharge capacitors by shorting across the capacitors terminals. (See Paragraph

3.5.8)
When disassembling wiring, use numbered stickers to identify wire leads and terminals. This aids in quick,

accurate reassembly.
Besurepoweristurnedoffbeforeworkingonmotors,controllers, or electricalcontrolswitches.Taganycircuit

breakers and power supply to prevent accidental energizing of circuits.
Do not bypass any electrical safety devices, e.g. bridging an overload, or using any sort of jumper wires.

Problems with the system should be diagnosed and any necessary repairs must be performed by qualified
service personnel.

In case of electrical fire, open circuit switch and extinguish with CO

SECTION 1

DESCRIPTION

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
UpperUnitandtheCeilingunit.TheUpperUnitcontains
the refrigeration system while the Ceiling Unit contains
thecontrols andvents. The Ceiling Units are availablein
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.

Theductedunits(seeFigure 1-5andFigure 1-6)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 (thermostat), which
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 model numbers and descriptions of the
AirV units, and Table 1-2 lists additional support
manuals that are available.

1.2 SERIAL NUMBER IDENTIFICATION

Separatepartnumbersandserialnumbersareprovided
for the upper and lower unit assemblies The numbers
may be found on a plate readable from inside the
vehicle, See Figure 1-7.

The first two numbers of the serial number, see
Figure 3-22, is theweektheunitwasmanufactured. 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
would represent the year 1999, 00 the year 2000, and
so on.

The letter Y and all the numbers after it designates the
unit serial number. Example: Y43210

Aserialnumber of 1303Y12345 designates that the unit
was manufactured the 13th week of 2003 and the serial
number is Y12345.

1.3 DESIGN CHANGE DESCRIPTIONS

The following list provides a description of changes in
design and serial number breaks for those changes.

1400Y A diode was added to the Ducted Ceiling
assembly control board to stop DC ripple from the
converters,

2900Y Cover screw coating was changed in order to
eliminate corrosion.

3400Y The plastic shroud was modified to improve
drainage.

5100Y A new compressor and capacitor is introduced,
improving stability and increasing capacity.

1201Y The temperature sensor was moved to the grill
to improve temperature sensing during furnace mode,

2501Y The dual air sweep was added.
4501Y A switch was added to skip compressor

malfunction test.
4601Y Change in material was made in order to

strengthen the fan propeller.
4901Y The mounting bolt lengths were increased 3/4

inch.

4901Y The polar whiteducted ceiling color was cut--in.
