OIL
Oil Adjusting Procedure for Compressor Replacement
INFOID:0000000008968517
1. Drain oil from removed compressor and measure amount drained.
• Drain oil from high-pressure port (A) and low-pressure port (B)
while rotating magnet clutch.
• Measure total amount of oil that is drained from removed com-
pressor.
2. Drain oil from a new compressor that is calculated according to
the following conditions.
CAUTION:
If oil amount that is drained from removed compressor is less than 60 m (2.1 Imp fl oz.), perform
calculation by setting “D” as 40 m (1.4 Imp fl oz.).
Example: Oil amount to be drained from a new compressor when replacing compressor [m (Imp fl oz.)]
[D = 60 (2.1),
α = 5 (0.2)]
120 (4.2)
− [60 (2.1) + 20 (0.7) + 5 (0.2)] = 35 (1.1)
3. Install compressor and check the operation.

30 (1.1)
Small amount leakage

INSPECTION PROCEDURE
1. Connect recovery/recycling/recharging equipment (for HFC-134a) or manifold gauge set.
2. Start the engine, and set to the following condition.
Test condition
3. Maintain test condition until A/C system becomes stable. (Approximately 10 minutes)
4. Check that test results of “recirculating-to-discharge air temperature” and “ambient air temperature-to-
operating pressure” are within the specified value.
5. When test results are within the specified value, inspection is complete.
If any test result is out of the specified value, perform diagnosis by manifold gauge set. Refer to
