• If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and

abnormal noise will occur. Always immediately plug open fittings after removing any refrigeration
cycle parts to keep moisture or foreign material out of the cycle.

5. Remove in the order indicated in the table. Do not

allow compressor oil to spill.

.

A/C Compressor Installation Note

Caution

• Due to the high moisture-absorption characteristics of the compressor oil, it may absorb moisture

if left over a long period of time thereby negatively affecting A/C operation. Drain the compressor
oil and refill within 10 min. of each other.

1. Rotate new A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a clean measuring

device. Use this refrigerant oil to refill new A/C compressor. Do not allow refrigerant oil to become
contaminated.

2. Rotate old A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a separate, clean

measuring device.

3. Compare those oil amounts. The amount of the oil drained from the new A/C compressor should be greater

than the old one.

4. Pour the same amount oil of drained from the old A/C compressor back into the new A/C compressor.

A/C compressor oil type

• ATMOS GU10

A/C compressor oil sealed volume (approx. quantity)

• 120 ml {120 cc, 4.06 fl oz}

5. Remove in the order indicated in the table. Do not allow compressor oil to spill.

Caution

• If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and

abnormal noise will occur. Always immediately plug all open fittings after removing any
refrigeration cycle parts to keep moisture or foreign material out of the cycle.

6. Install in the reverse order of removal.
7. Perform the refrigerant system performance test. (See 07-10-6 REFRIGERANT SYSTEM PERFORMANCE

Refrigerant Line Removal Note
Spring-lock coupling type

1. Set the SST.

2. While looking through the inspection hole of the

SST, insert the protruding part of the SST until it
makes contact with the cage section.

3. Use the SST to disconnect the male pipe or hose

from the female by pulling the male pipe or hose.

Note

• The male pipe or hose can be disconnected

easily from the female pipe by pulling from
the male pipe or hose while maintaining the
pressure of the protruding part of the SST.

Refrigerant Line Installation Note

1. When installing a new cooler pipe or cooler hose, add a supplemental amount of ATMOS GU10 compressor oil

into the refrigeration cycle.

Supplemental amount (approx. quantity)
5 ml {5 cc, 0.2 fl oz}: Cooler pipe
10 ml {10 cc, 0.3 fl oz}: Cooler hose

2. Apply compressor oil to the O-rings and connect the joints.
