203 Air Conditioning System
Areas of Importance
1. When putting in a new compressor, adjust the new compressor's inner lubricant to make it the same
level as of the old compressor's.
2. When the air conditioner malfunctions, if the pipeline, condenser or evaporator is the source of the
damage leading to its replacement, just add model number RS20 professional lubricant 5
-
10 ml.
3. The compressor is a high speed operating component, the smallest impurity in the air conditioning
system can lead to the compressor's damage, therefore the entire air conditioning system must be
cleaned.
4. In order to avoid liquid damage to the compressor, pay careful attention when filling the refrigerant.
When the vehicle stopped, fill the liquid refrigerant from the high pressure side. When in operation, fill
the liquid refrigerant from the low pressure side.
5. When undergoing maintenance, pay attention that the amount of refrigerant being added is 510±10 g.
Observe through the check glass to determine if there is sufficient new refrigerant charge.
