Receiver Dryer: Service and Repair
CONDENSER
LIQUID TANK : Removal and Installation
CAUTION:
Perform lubricant return operation before each refrigeration system disassembly. However, if a large amount of refrigerant or lubricant is detected, never perform lubricant return operation. Refer to HA34, "Perform Lubricant Return Operation".
REMOVAL
1.Use the refrigerant recovery equipment (for HFC134a) and recover the refrigerant. Refer to "Recycle Refrigerant" Recycle Refrigerant.
2.Disconnect refrigerant pressure sensor connector (A).
3.Clean around the liquid tank to remove any dirt or corrosion.
4.Remove mounting bolts (A), and then remove liquid tank (1)
from condenser.
CAUTION:
To prevent the inclusion of foreign matter, use a cap or vinyl tape to seal off the connection ports of the liquid tank and condenser from the atmosphere.
INSTALLATION
Note the following items, and then install in the reverse order of removal.
CAUTION:
- To prevent degradation in insulation performance, use special electric compressor oil as the compressor oil.
- In order to prevent conventional PAG oil from becoming mixed in, never reuse recovered compressor oil and instead always use new oil. The use of oil including the conventional PAG oil may degrade the performance of insulation.
- To prevent performance degradation, never use a fluorescent agent in order to detect refrigerant leakage. Also be careful that a fluorescent agent never enter the oil.
- After installing a new liquid tank, adjust the compressor oil level. Refer to "Lubricant Adjusting Procedure for Components Replacement Except Compressor" Lubricant Adjusting Procedure For Components Replacement Except Compressor.
- To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil to the O-ring prior to installation.
- Perform a check for refrigerant leakage when charging with refrigerant. Refer to "Check Refrigerant Leakage" Check Refrigerant Leakage.
