IMPORTANT INFORMATION WHEN WORKING WITH A/C Service Station

• The filters and dryers installed must be replaced, at the latest, when the service life specified in the relevant operating instructions has been reached.
• Only refrigerant oils that are approved for the refrigerant circuit in that vehicle may be added.

Refer to the Parts Information.

Extracted refrigerant must not be reused under the following conditions, even after cleaning in the station:

• In the case of A/C compressor damage in which the refrigerant was disintegrated due to overheating.
• In the case of dark, sticky deposits in the refrigerant circuit (these can only be found after opening the system).
• If there is any doubt as to the composition of the refrigerant extracted from the refrigerant circuit.

The A/C Service Station is to be drained in all these cases. The system is cleaned if necessary, and the filters, dryers and refrigerant oil are replaced. Refer to REFRIGERANT CIRCUIT, DISCHARGING WITH A/C Service Station .

For example, within Germany, contaminated refrigerant can be returned to the supplier in recycling containers for recycling or for environmentally safe disposal. Other or additional regulations may apply in other countries.

Commercially available A/C service stations can be classified in 2 groups:

• A. A/C service stations that clean extracted refrigerant for reuse (extraction and recycling stations), such as the A/C Service Station.

• B. A/C service stations that transfer extracted refrigerant to recycling containers (for large-scale recycling). These are referred to as extraction systems.
