REMOVAL SERVICE POINTS
<> DRIVE BELT REMOVAL
CAUTION: When reusing the drive belt, mark an arrow which indicates the turning direction (right turn) on the back of the drive belt with a chalk, etc.
Insert the socket-wrench handle into the tool hole for auto-tensioner and turn it to the arrow direction. Reduce the drive belt tension and remove the drive belt.
<> DISCHARGE HOSE/SUCTION HOSE REMOVAL
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.

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 cu.cm (X floz)] of oil within the removed compressor.
2. Drain (from the new compressor) the amount [Y cu.cm (Y floz)] of oil calculated according to the following formula, and then install the new compressor.
New compressor oil amount = 120 cu.cm (4.2 floz)
New compressor oil amount = 140 cu.cm (4.9 floz)
120 cu.cm - X cu.cm = Y cu.cm (4.2 floz - X floz = Y floz)
140 cu.cm - X cu.cm = Y cu.cm (4.9 floz - X floz = Y floz)
NOTE: Y cu.cm (Y floz) 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 the each part from Y cu.cm (Y floz) and discharge from the new compressor.
Quantity:
- Evaporator: 60 cu.cm (2.0 floz)
- Condenser: 15 cu.cm (0.5 floz)
- Suction hose: 10 cu.cm (0.3 floz)
- Receiver: 10 cu.cm (0.3 floz)
