| Connecting air conditioner service station to refrigerant circuit with adapter set for refrigerant circuit -V.A.G 1786- |
| A - | Connection with valve (small valve core) at low-pressure side of refrigerant circuit |
| B - | Adapter with union nut -V.A.G 1786/1- |
| C - | Commercially available filler hose (short version with 5/8" thread on each end) |
| D - | Adapter with service connection -V.A.G 1786/2- (for connection of quick-release coupling of air conditioner service station -E-) |
Note | t
| Assemble adapter and filler hose as shown and start by connecting to connection with valve -A-. |
| t
| The adapter with union nut -V.A.G 1786/1- is only to be used at connections with a „small“ valve core (standard for connection with valve for low-pressure switch for air conditioning system -F73- and also gradually introduced as of 10.94 at the air conditioner compressor). |
| t
| Instead of adapter with union nut -V.A.G 1786/1-, you can also use adapter -V.A.G 1785/10- (remove valve from adapter -V.A.G 1785/10- or install valve opener in filler hose). |
