Lubricant Adjusting Procedure for Compressor Replacement
INFOID:0000000010122111
1. Drain lubricant from removed compressor and measure lubricant amount.
1. Turn the compressor so that it faces downward, and drain
the compressor oil from high-pressure port (A) and low-
pressure port (B).
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 [m (Imp fl
oz)] [D = 60 (2.1),
α = 5 (0.2)]
150 (5.3)
− [60 (2.1) + 20 (0.7) + 5 (0.2)] = 65 (2.3)
3. Install compressor and check the operation.

F
: Lubricant amount that a new compressor con-
tains [150 (5.3)]

: Lubricant amount that is drained from removed
compressor
S
: Lubricant amount that remains inside of removed
compressor [20 (0.7)]
R
: Lubricant amount to be added according to com-
ponents that are removed except compressor
