SEAT Workshop Service and Repair Manuals

Adapters to create rinsing circuits t  In the following table are the various adapters, which are necessary to connect the air conditioning service station to the refrigerant circuit for purposes of rinsing and to bridge the removed receiver or reservoir and expansion valve (vehicle-specific). t  Using a filling hose with 5/8 -18 UNF connections (short version, e.g. filling hose -VAS 6338/31-), join both adapters, which were installed in place of the reservoir or receiver (included in adapter case SEAT passenger vehicle set -VAS 6338/1-). t  If a rinsed refrigerant circuit is not going to be reassembled straight after rinsing, leave the adapters on the connections and seal the connections at the adapters using the sealing caps -VAS 6338/30- (from adapter case SEAT passenger vehicle set -VAS 6338/1-). t  Depending on the type of A/C compressor and the period of production, different joining and sealing techniques have been applied in the refrigerant circuit → Heating, air conditioning.
