Refrigerant Oil: Service Precautions
Precautions on Replenishing Compressor Oil
When replacing air conditioning parts with new ones, it is necessary to replenish oil by the amount supposedly remaining in each part.
When Charging Refrigerant Only
When charging refrigerant without replacing any component, replenish the same amount of measured oil when recovering refrigerant (if not measure,
replenish 20 cu.cm (20 cc) oil).
When Replacing Compressor
CAUTION: Be sure to use specified compressor oil or an equivalent compressor oil.
Compressor oil is sealed in each new compressor (1) by the amount required for air conditioner cycle. Therefore, when using a new compressor for
replacement, drain 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.
