SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers
to an CFC-12 (R-12) A/C system. The HFC-134a (R-134a) cou-
plers will not properly connect to the CFC-12 (R-12) system.
However, if an improper connection is attempted, discharging
and contamination may occur.
Shut off valve rotation A/C service valve
Clockwise Open
Counterclockwise Close
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and
specified lubricants have been used with the scale. If the scale
controls refrigerant flow electronically, the hose fitting must be
1/2²-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may
be vented into air from cylinder's top valve when filling the cylin-
der with refrigerant. Also, the accuracy of the cylinder is gener-
ally less than that of an electronic scale or of quality recycle/
recharge equipment.

HA-11

Refrigeration Cycle
REFRIGERANT FLOW
The refrigerant flow is in the standard pattern. Refrigerant flows through the compressor, condenser, liquid
tank, evaporator, and back to the compressor.
The refrigerant evaporation through the evaporator coil is controlled by an externally equalized expansion
valve, located inside the evaporator case.
FREEZE PROTECTION
Variable displacement (CSV613)
Under normal operating conditions, when the A/C is switched on, the compressor runs continuously, and the
evaporator pressure, therefore temperature, is controlled by the CSV613 variable displacement compressor
to prevent freeze up.
Vane rotary (CR-14)
The compressor cycles on and off to maintain the evaporator temperature within a specified range. When
the evaporator coil temperature falls below a specified point, the thermo control amplifier interrupts the
compressor operation. When the evaporator coil temperature rises above the specification, the thermo con-
trol amplifier allows compressor operation.
REFRIGERANT SYSTEM PROTECTION
Dual-pressure switch (System with CR-14 compressor)
The refrigerant system is protected against excessively high or low pressure by the dual-pressure switch,
located on the liquid tank. If the system pressure rises above, or falls below the specifications, the dual-
pressure switch opens to interrupt the compressor operation.
Pressure sensor (System with CSV613 compressor)
The pressure sensor is located on the liquid tank. It converts the system pressure into a voltage value witch
is then input into ECM.
If the system pressure rises above, or falls below the specifications, ECM interrupt the compressor opera-
tion.
Fusible plug
Open at temperatures above 105ÉC (221ÉF), thereby discharging refrigerant to the atmosphere. If this plug
is melted and opened, check the refrigerant line and replace liquid tank.
Pressure relief valve (CSV613 compressor)
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compres-
sor. When the pressure of refrigerant in the system increases to an abnormal level [more than 3,727 kPa
(38 kg/cm
2, 540 psi)], the release port on the pressure relief valve automatically opens and releases refrig-
erant into the atmosphere.
DESCRIPTION
HA-12

CSV613 Variable Displacement Compressor
GENERAL INFORMATION
1. The CSV613 compressor differs from previous units. The vent temperatures of the CSV613 compress
or do not drop too far below 5ÉC (41ÉF) when:
levaporator intake air temperature is less than 20ÉC (68ÉF)
lengine is running at speeds less than 1,500 rpm.
This is because the CSV613 compressor provides a means of ªcapacityº control.
2. The CSV613 compressor provides refrigerant control under varying conditions. During cold winters, it
may not produce high refrigerant pressure discharge (compared to previous units) when used with air
conditioning systems.
3. A ªclankingº sound may occasionally be heard during refrigerant charge. The sound indicates that the
tilt angle of the swash plate has changed and is not a problem.
4. For air conditioning systems with the CSV613 compressor, the clutch remains engaged unless: the sys-
tem main switch, fan switch or ignition switch is turned OFF. When ambient (outside) temperatures are
low or when the amount of refrigerant is insufficient, the clutch is disengaged to protect the compressor.
5. A constant range of suction pressure is maintained when engine speed is greater than a certain value.
It normally ranges from 147 to 177 kPa (1.47 to 1.77 bar, 1.5 to 1.8 kg/cm
2, 21 to 26 psi) under vary-
ing conditions.
In previous compressors, however, suction pressure was reduced with increases in engine speed.
