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.
Refrigerant leak is detected
Large amount leakage
30 (1.1)
Small amount leakage
—
Oil amount that is recycled together with refrigerant during recycle operation

+ S + R +
α)
F:
Oil amount that a new compressor contains
[120 (4.2)]
D: Oil amount that is drained from removed com-
pressor
S: Oil amount that remains inside of removed
compressor [20 (0.7)]
R: Oil amount to be added according to compo-
nents that are removed except compressor
α: Oil amount that is recycled together with re-
frigerant during recycle operation
