INSTALLATION SERVICE POINT
>>A<< A/C 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 mL) 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 = 140mL <1300,
1600>, 120 mL <2000>
140 mL−X mL = Y mL <1300, 1600>
120 mL−X mL = Y mL <2000>
NOTE: Y mL 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 mL and discharge
from the new compressor.
Quantity:
•Evaporator: 60 mL
•Condenser: 15 mL
•Suction hose: 10 mL
•Receiver: 10 mL

COMPRESSOR MAGNETIC CLUTCH
OPERATION CHECK
Connect the compressor connector terminal to the
battery positive (+) terminal and earth the battery’s
negative (−) terminal to the compressor unit. At that
time, the magnetic clutch should make a definite
operating sound.

CAUTION
As the compressor oil and receiver are highly
moisture absorbent, use a non-porous material
to plug the hose and nipples.
To prevent the entry of dust or other foreign bodies,
plug the dismantled hose and condenser assembly
nipples.
INSTALLATION SERVICE POINT
>>A<< CONDENSER INSTALLATION
When replacing the condenser, refill it with a
specified amount of compressor oil and install it. (to
the vehicle).
Compressor oil: SUN PAG 56
