General Information For Cleaning Refrigerant Circuit

• Refrigerant circuit must be cleaned, in order to- be able to force out moisture and other contaminants as well as old refrigerant oil as efficiently as possible, without wasting refrigerant, without the need for extensive assembly work and without endangering the environment.
• Vehicle-specific, certain components must be replaced after flushing. Refer to or ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT .

Clean the refrigerant circuit if the following apply (flushing):

• When there is dirt or other contamination in the refrigerant circuit.
• When the refrigerant circuit has been left open for longer than normal (for example, after a collision).
• When it is not clear how much refrigerant oil is in the refrigerant circuit.
• When it is not clear which type of refrigerant oil was used before.
• If the A/C compressor had to be replaced due to internal damage (for example, noise or no output). Refer to COMPONENTS, REPLACING .
• When it is stipulated by the vehicle-specific service information following the replacement of certain components.
