REMOVAL SERVICE POINTS

<<A>> DRIVE BELT REMOVAL
1. Loosen the nut "A" for holding.

2. Loosen the bolt "B" for adjustment.

3. Remove the drive belt.

<<B>> DISCHARGE HOSE AND SUCTION HOSE 
DISCONNECTION

CAUTION

Seal the hoses completely, otherwise the compressor oil 
and receiver will absorb water vapor easily, possibly 
damaging the compressor and deteriorating performance.
Plug the disconnected hose and compressor nipple to prevent 
foreign matter from getting into them.

<<C>> COMPRESSOR REMOVAL
When removing the compressor, be careful not to spill the 
compressor oil.

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 floz)] 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.
