INSTALLATION SERVICE POINT

.

>>A<< COMPRESSOR INSTALLATION

If a new compressor is installed, first adjust the amount of oil 
according to the 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

 (4.7 fl.oz. 

− X fl.oz. = Y fl.oz)

NOTE: Y cm

 (Y fl.oz) indicates the amount of oil in the refrig-

erant 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 cm

COMPRESSOR CLUTCH OPERATION CHECK

Connect the compressor connector terminal to the battery posi-
tive (+) terminal and ground the battery’s negative (-) terminal 
to the compressor unit. At that time, the air conditioning com-
pressor clutch should make a definite operating sound.
