procedures described below, and then install the compressor.
1. Measure the amount [X cm
3 (X fl.oz) of oil within the removed compressor.
2. Drain (from the new compressor) the amount of oil calculated according to the
following formula, and then install the new compressor.
New compressor oil amount = 140cm
2 (4.7 fl.oz)
140 cm
3 - X cm
3 = Y cm
3 (4.7 fl.oz. - X fl.oz. = Y fl.oz)
Quantity:

Eva
porator
: 60 c
m3 (2.0 fl.oz
)
CAUTION: As the compressor oil and receiver are highly
moisture absorbent, use a non-porous material to
plug the hose and nipples.
NOTE:
Y cm
3 (Y fl.oz) indicates the amount of oil in the refrigerant
line, the condenser, the evaporator, etc.
NOTE: When replacing the following parts at the same times as the
compressor, subtract the rated oil amount of each part from
Y cm3 (Y fl.oz) and discharge from the new compressor.
