Refrigerant Oil: Testing and Inspection
Replenishing Compressor Oil
It is necessary to replenishing specified amount of compressor oil to compressor (1) from compressor suction side hole (2) before evacuating and
charging refrigerant.
When charging refrigerant only
When charging refrigerant without replacing any component part, replenish the same amount of measured oil when recover refrigerant (if not measure,
replenish 30 cu.cm (30 cc) oil).
When replacing compressor
Compressor oil is sealed in each new compressor by the amount required for A/C system. Therefore, when using a new compressor for replacement,
drain excess oil from it by the amount calculated as follows.
"C"="A" - "B"
"C": Amount of oil to be drained
"A": Amount of oil sealed in a new compressor
"B": Amount of oil remaining in removed compressor
NOTE: Compressor assembly supplied from factory is filled up with the following amount of oil.
Oil amount in compressor: 100 cu.cm (100 cc)
When replacing other part
Replenish the following amount of oil to compressor.
Amount of compressor oil to be replenished
Replaced part: Amount of compressor oil
Evaporator: 25 cu.cm (25 cc)
Condenser: 15 cu.cm (15 cc)
