Caution
Lay the towel on the brake tube to protect them. When
installing the compressor, do not damage the brake tubes.

compressor oil.
INSTALLATION SERVICE POINT
If a new compressor is installed, first adjust the amount of
oil according to the procedures described below, and then
install the compressor.

removed compressor.
(2) Wipe away (from the new compressor) the amount of
oil calculated according to the following formula, and then
install the new compressor.
New compressor oil amount 160 cm3 - X cm3 = Y cm3
(5.4 fl.oz. - x fl.oz. = Y fl.oz.)
NOTE
(1) Y cm3 (Y fl.oz.) indicates the amount of oil in the refrigerant
line, the condenser, the cooling unit, etc.
(2) If any other air conditioning part is replaced simultaneously
with the compressor, remove the oil from the new
