Compressor HVAC: Service and Repair

REMOVAL AND INSTALLATION













REMOVAL SERVICE POINTS

[[A]] FLEXIBLE SUCTION HOSE AND FLEXIBLE DISCHARGE HOSE DISCONNECTION

CAUTION:
As the compressor oil and receiver are highly moisture absorbent, use a non-porous material to plug the hose and nipples.

To prevent the entry of dust or other foreign bodies, plug the dismantled hoses and compressor nipples.

[[B]] A/C COMPRESSOR REMOVAL

Take care not to spill any compressor oil when removing the compressor.

INSTALLATION SERVICE POINT

]]A[[ A/C COMPRESSOR INSTALLATION

If a new compressor is installed, first adjust the amount of oil according to the procedures described below, and then install the compressor.

1. Measure the amount X cm3 (X fl.oz) of oil within the removed compressor.

2. Drain (from the new compressor) the amount of oil calculated according to the following formula, and then install the new compressor.
New compressor oil amount = 140cm2(4.7 fl.oz)

140 cm3 - X cm3 = Y cm3 (4.7 fl.oz - X fl.oz = Y fl.oz)


NOTE:

- Y cm3 (Y fl.oz) indicates the amount of oil in the refrigerant line, the condenser, the evaporator, etc.
- When replacing the following parts at the same times as the compressor, subtract the rated oil amount of each part from Y cm3 (Y fl.oz) and discharge from the new compressor.

Compressor oil:SUN PAG 56
Quantity:

Evaporator: 60 cm3 (2.0 fl.oz)
Condenser: 15 cm3 (0.5 fl.oz)
Suction hose: 10 cm3 (0.3 fl.oz)
Receiver: 10 cm3 (0.3 fl.oz)
