SAFETY SUMMARY
GENERAL SAFETY NOTICES
The following general safety notices supplement the specific warnings and cautions appearing elsewhere in this manual. They are recommended precautions that must be understood and applied during operation and maintenance of the equipment covered herein. The general safety notices are presented in the following three 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 cover assembly before turning the power off, and disconnecting the power supply. Before disconnecting, discharge capacitors by shorting across the capacitors terminals. (See Paragraph 3.6.8)
When disassembling wiring, use numbered stickers to identify wire leads and terminals. This aids in quick, accurate reassembly.
Be sure power is turned off before working on motors, controllers, or electrical control switches. Tag any circuit 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 CO2 (never use water).
Use dry nitrogen to pressurize the system for leak checking. Be careful not to exceed 150 psig test pressure in the hermetic compressor.
Coil fins are sharp. Use care when removing the cover form the base pan to avoid personal injury.
Oil vapor in piping stubs can ignite from torch flame and cause serious injury. Exercise extreme care when brazing, and keep brazing cloth and fire extinguisher handy for emergency use.
Disconnect power to the AirV unit before checking the capacitor.

SPECIFIC WARNING AND CAUTION STATEMENTS
The statements listed below are applicable to the refrigeration unit and appear elsewhere in this manual. These recommended precautions must be understood and applied during operation and maintenance of the equipment covered herein.
SPECIFIC WARNINGS AND CAUTIONS
WARNING
Be sure to observe warnings listed in the safety summary in the front of this manual before performing maintenance on the AirV system
WARNING
Before working on the unit be sure to first disconnect all electric power to the unit to avoid the possibility of electrical shock and personal injury. Before disconnecting, discharge capacitors by shorting across the capacitors terminals (Refer to paragraph 3.6.8)
WARNING
Shield coils with cardboard to protect hands against injury from sharp metal edges when removing compressor and other components.
WARNING
Oil vapor in piping stubs can ignite from torch flame and cause serious injury. Exercise extreme care when brazing, and keep brazing cloth and fire extinguisher handy for emergency use.
WARNING
Disconnect power to the AirV unit before checking the capacitor.
WARNING
Do not touch the metal of the screwdriver when discharging the capacitor. You could receive a shock.
WARNING
Before installing thermostat, turn off all power to unit. There may be more than one power disconnect. Electrical shock can cause personal injury or death.
CAUTION
In order for the AirV systems to operate efficiently, a dedicated 115 Volt 20 Amp power connection is required.

CAUTION
Do not use carbon tetrachloride, solvents, or waxes containing solvents to clean plastic sections.
CAUTION
Coil fins are sharp. Use care when removing the cover form the base pan to avoid personal injury.
CAUTION
The change from Fahrenheit to Celsius will be permanent. It cannot be changed back to Fahrenheit.
CAUTION
When re--assembling, ensure the battery springs are correctly placed in the battery spring holders.
CAUTION
Improper wiring or installation may damage thermostat. Wiring must conform to local and national electrical codes.

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