AIR CONDITIONING 1B-5 The receiver/drier of this vehicle is made of aluminum with a smaller tank. It has 250cc (7.1 Imp fl oz) refriger- ant capacity. For Taiwan Dual Pressure Switch (for GCC and Taiwan) The dual pressure switch (1) is installed on the upper part the receiver/drier (2), to defect excessively high pressure (high pressure switch) and prevent compres- sor seizure due to the refrigerant leaking (low pressure switch), switching the compressor “ON” or “OFF” as re- quired. The pressure switch connector is water proof type. R-134a refrigerant pressure characteristics differ from those of R-12. Thus, the dual pressure switch operation for R-134a systems has been changed from R-12.
Low-pressure control (for GCC) kPa (kg/cm 2 / PSI) Compressor ON: 206 ± 30 (2.1 ± 0.3 / 30 ± 4) OFF: 177 ± 25 (1.8 ± 0.2 / 26 ± 3) High-pressure control (for GCC) Compressor Triple Pressure Switch (for Australia) N1A0049E The triple pressure switch (1) is installed on the upper part of the receiver/drier (2). This switch is constructed with a unitized type of two switches. One of them is a low and high pressure switch (Dual pressure switch) to switch “ON” or “OFF” the magnetic clutch as a result of irregularly high-pressure or low-pressure of the refriger- ant.
The other one is a medium pressure switch (Cycling switch) to switch “ON” or “OFF” the condenser fan by sensing the condenser high side pressure. ON: 2,350 ± 200 (24.0 ± 2.0 / 341 ± 29) OFF: 2,940 ± 200 (30.0 ± 2.0 / 426 ± 29) Low-pressure control (for Taiwan) Compressor ON: 221 ± 20 (2.25 ± 0.2 / 32 ± 3) OFF: 196 ± 20 (2.0 ± 0.2 / 28 ± 3) High-pressure control (for Taiwan) Compressor ON: 2,350 ± 200 (24.0 ± 2.0 / 341 ± 29) Low-pressure control kPa (kg/cm 2 / PSI) Compressor OFF: 2,940 ± 200 (30.0 ± 2.0 / 426 ± 29) For GCC ON: 206 ± 30 (2.1 ± 0.3 / 30 ± 4) OFF: 177 ± 25 (1.8 ± 0.2 / 26 ± 3) Medium-pressure control Condenser fan ON: 1,470 ± 100 (15 ± 1.0 / 213 ± 14) OFF:
1,079 ± 120 (11 ± 1.2 / 156 ± 17) 1 High-pressure control Compressor ON: 2,350 ± 200 (24.0 ± 2.0 / 341 ± 29) OFF: 2,940 ± 200 (30.0 ± 2.0 / 426 ± 29) 2 N1A0048E
