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.

REFRIGERANT TEMPERATURE SWITCH
CAUTION
Do not heat more than necessary.
1. Dip the metal part of the cooling temperature
switch into engine oil and increase the oil
temperature using a gas burner or similar.
2. When the oil temperature reaches the standard
value, check that voltage is supplied between the
terminals.
Standard value:
NOTE: When the oil temperature is 150
°C or
more and there is no continuity, the resistance will
not be 2
Ω or lower until the oil temperature
reduces to 120
°C or less.
