Service Station, Important Usage Information

Observe the following with regard to service station operation. Refer to the Parts Information (Tools; Special Tools and Equipment: A/C and Heating).

-- The filters and dryers installed must be replaced at the latest on completion of the service life specified in the relevant operating instructions.

-- If a service station is also used for cleaning (flushing) the refrigerant circuit, dryer and filter must be replaced in shorter intervals. Refer to REFRIGERANT CIRCUIT, FLUSHING WITH COMPRESSED AIR AND NITROGEN .

-- Only refrigerant oils which have been approved for the refrigerant circuit in that vehicle may be added (if necessary, fill refrigerant oil directly into refrigerant circuit). Refer to the Parts Information.

Extracted refrigerant is not to be reused if there is any doubt about the composition of the refrigerant extracted, even after cleaning in the service station.

-- The service station is to be drained in all these cases. Refer to A/C SERVICE STATION, CONNECTING ). The system is cleaned if necessary and the filters, dryers and refrigerant oil are replaced.

-- 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 service stations can be classified in two groups:

• Service stations which clean extracted refrigerant for use (so-called extraction and recycling stations for currently available service stations). Refer to the Parts Information (Tools; Special Tools and Equipment: A/C and Heating).

• Service stations which transfer extracted refrigerant to recycling containers (for large-scale recycling). These are referred to as extraction systems.
