Lubricant Adjusting Procedure for Compressor Replacement
INFOID:0000000006032324
1.
Drain lubricant from removed compressor and measure lubricant amount.
1.
Drain lubricant from high-pressure port (A) and low-pres-
sure port (B) while rotating magnet clutch.
2.
Measure total amount of lubricant that is drained from removed compressor.
2.
Drain lubricant from a new compressor that is calculated accord-
ing to the following conditions.
CAUTION:
If lubricant 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: Lubricant amount to be drained from a new compressor when replacing compressor and liquid
tank [m (Imp fl oz.)] [D = 60 (2.1),
α
= 5 (0.2)]
Conditions
Lubricant amount to be added to A/C system
m
(Imp fl oz.)
Replace evaporator
35 (1.2)
Replace condenser
15 (0.5)
Replace liquid tank
5 (0.2)
Refrigerant leakage is detected
Large amount leakage
30 (1.1)
Small amount leakage
—
Lubricant amount that is recycled together with refrigerant during recycle operation

F
: Lubricant amount that a new compressor
contains [120 (4.2)]
D
: Lubricant amount that is drained from re-
moved compressor
S
: Lubricant amount that remains inside of re-
moved compressor [20 (0.7)]
R
: Lubricant amount to be added according to
components that are removed except com-
pressor
