Pressure Switch --The systems use high and low pressure switches wired in series to control the power circuit of the compressor clutch relay. If either pressure switch opens, interrupting the circuit to the clutch relay, the operation of the compressor will stop. When conditions return to normal the switch will automatically reset and the compressor will resume operating. The switches are non--adjustable.

Freeze--Up Thermostat --Freeze--up thermostats are used to prevent ice formation on the evaporator coil, which is an indication that liquid refrigerat is getting back to the compressor. Carrier Transport Air Conditioning systems use a freeze thermostat (freezestat) wired in series with the system pressure switches and thermostat/thermistor to control the operation of the compressor clutch.

Refrigerant --A refrigerant is a material that is used to move heat from the passenger compartment to the outside air. It is a substance that gives up heat by condensing at high temperature and pressures and absorbs heat by evaporating at low temperatures and pressures. The heat transfer properties exhibited when refrigerant changes state is the foundation of the refrigerant cycle.

1.5 MODEL AND SERIAL NUMBER TAGS

In order to identify the air conditioning components you have, you will need to know the model number and serial number. All Carrier Transport Air Conditioning evaporators, condensers and compressors have a model/serial number tag located on the assembly. See Figure 1-2 for skirt mounted condenser data tag location, Figure 1-3 for the CM--7/11 rooftop condensers data tag location, Figure 1-4 for GEN 4 (Excel) evaporator data tag location and Figure 1-5 for GEN 5 evaporator data tag location. Knowing these locations and the information on the data tags will aid you in identifying the correct service procedures.
