-- Remove the cap from the connection with valve -A- (at A/C compressor).

-- Attach the O-ring -B- to the connection (8.9 mm; 1.8 mm).

-- Screw the Adapter:VAG1785/10 -C- onto the connection -B-.

-- Install the valve opener -D- with the appropriate seal in the charging hose connection.

NOTE:

The type of valve opener -D- and seals required depends on charging hose used (specific to manufacturer).

The quick-release coupling adapter is not required for connection on the low-pressure side of Audi vehicles.

Screw the charging hose -E- (to the service station) onto the A/C Adapter Set - Adapter 10:VAG1785/10 .

NOTE:

To minimize the amount of air and moisture penetrating into the charging hoses and thus into the refrigerant circuit, the charging hoses should be connected together as illustrated.
