HVAC Climate Control System: Removal & Installation Ford Focus II рестайлинг

REMOVAL AND INSTALLATION

Note. Installation of a new receiver/drier is not required when repairing the A/C system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to the receiver/drier includes leaks in the receiver/drier, physical damage to the receiver/drier shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant, and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant pressure is present, and physical evidence of contamination from an A/C compressor failure is not present in the system before repairs are carried out, a new receiver/drier should not be installed.
