Volkswagen Touran Service Manual: Adapter for Assembling Flushing Circuit

Volkswagen Touran Service Manual / Heating, Ventilation and Air Conditioning / Refrigerant Circuit, Removing Contaminants / Refrigerant Circuit, Flushing (Cleaning) with Refrigerant R134a / Adapter for Assembling Flushing Circuit

The following table lists the different adapters necessary to connect the service station to the refrigerant circuit, to flush and to bypass the removed receiver/dryer or reservoir and expansion valve (depending on the vehicle).
Using a charge hose with 5/8 -18 UNF connections (short version, for example Refrigerant Circuits Adapter Set 1 - Hose 31 -VAS6338/31-), connect the two adapters (contained in Refrigerant Circuits Adapter Set 1 -VAS6338/1-) which have been installed for the removed reservoir or receiver/dryer.
If a flushed refrigerant circuit is not reassembled immediately after flushing, adapters remain at connections and seal the connections at the adapters using Refrigerant Circuits Adapter Set 1 - Adapter 30 -VAS6338/30- (from Refrigerant Circuits Adapter Set 1 -VAS6338/1-).
Depending on the version of the A/C compressor and on the time period of production, various connecting and sealing technologies can be found on the refrigerant circuit. Refer to Heating, Ventilation and Air Conditioning.

The restrictor in the refrigerant line to the High-Voltage Battery Heat Exchanger is removed and drilled out. Refer to the notes below → Anchor
 
  Note
The refrigerant circuit is flushed in 2 phases for the Golf Hybrid 2014. In the first flushing cycle the adapter for the heater and a/c unit refrigerant cut-off valve - N541 is opened and the adapter for the high voltage battery heater core refrigerant cut-off valve - N542 is closed. From this, the refrigerant circuit with the evaporator in the Heater and A/C Unit is flushed. In the second flushing cycle the adapter for the heater and a/c unit refrigerant cut-off valve - N541 is closed and the adapter for the high voltage battery heater core refrigerant cut-off valve - N542 is open. From this, the refrigerant circuit with the evaporator in the high voltage battery heat exchanger is flushed. Refer to Heating, Ventilation and Air Conditioning, Repair group 87, System Overview - Refrigerant Circuit (vehicle-specific repair manual).
  Note
    
This illustration shows a refrigerant line -A- with a permanently installed restrictor -B- (without a strainer) This refrigerant line is to be drilled open to 5.0 mm using a suitable drill to flush the refrigerant circuit (an inserted restrictor is to be removed) and is to be cleaned in the flushing circuit before installing. The drilled refrigerant line is replaced after flushing. Refer to the Parts Catalog.
The diameter of the illustrated restrictor bore -B- is approximately 0.7 mm. Depending on the version of the refrigerant line this constriction is either installed fixed in the refrigerant line or only inserted. For the inserted version a strainer for flowing deposits may be installed, which can be blocked by the variable orifice.
