GENERAL REPAIR PROCEDURE
OIL SPECIFICATION
•
The HFC-134a system requires a synthetic (PAG)
compressor oil.
• Compressor (PAG) oil varies according to compressor
model. Be sure to use oil specified for the model of
compressor.
Specified Compressor Oil
DH-PR



HANDLING OF OIL
•
The oil should be free from moisture, dust, metal powder,
etc.
• Do not mix with other oil.
• The water content in the oil increases when exposed to the
air. After use, seal oil from air immediately.
• The compressor oil must be stored in steel containers, not
in plastic containers.

COMPRESSOR OIL CHECK
The Oil used to lubricate the compressor is circulating with the
refrigerant.
W henever replacing any component of the system or a large
amount of gas leakage occurs, add oil to maintain the original
amount of. oil.

Checking and Adjusting for Compressor
Replacement
180 cm3 (5.07 lmp fl oz) of oil is charged in compressor
(service parts). So it is necessary to drain the proper amount
of oil from the new compressor.
1) Perform oil return operation.
2) Discharge refrigerant and remove the compressor.
3) Drain the compressor oil and measure the extracted oil.
4) Check the compressor oil for contamination.
5) Adjust oil level as required.
Amount of oil drained

6) Evacuate, charge and perform oil return operation.
7) Check system operation.


CONTAMINATION OF COMPRESSOR OIL
Unlike engine oil, no cleaning agent is added to the
compressor oil. Even is the compressor runs for a long period
of time (approximately 1 season), the oil never becomes
contaminated as long as there is nothing wrong with the
compressor or its method of use.
Inspect the extracted oil for any of the following
conditions:
• The capacity of the oil has increased.
• The oil has changed color to red.
• Foreign substances, metal powder, etc., are present in the
oil.
If any of these conditions exists, compressor oil is
contaminated. Whenever contaminated compressor oil is
discovered, the receiver/drier must be replaced.
