| Connections with Schrader valve (needle valve) |
| t
| -A- Service connection (soldered in) |
| t
| -B- Valve core (designation: Schrader valve or needle valve) |
| t
| -D- Sealing cap with seal |
Note | t
| Following connection, carefully screw the handwheel of the service coupling into the quick-release coupling adapter to the extent required to reliably open the valve in the service connection (observe the pressure gauge; take care not to open the valve too far). |
| t
| To remove and install the valve core -B- with the refrigerant circuit drained, make use of an adapter from the socket -T10364- for example. |
| t
| Take care when tightening valve core -B- (low torque). |
| t
| There are different versions of these valves and the tightening torques therefore also differ. The tightening torque for a valve core -B- with a VG5 thread (5.2 x 0.7 mm, tyre valve) is 0.4 Nm 0.1 Nm. For a valve core with an M6 x 0.75 mm thread, the tightening torque is 0.9 Nm 0.1 Nm and for a valve core with an M8 x 1.0 mm thread it is 2.0 Nm 0.2 Nm. |
| t
| There are different versions of these valves, the valve cores and the corresponding sealing caps. Attention is to be paid to the correct version of the valve core and correct assignment of the sealing caps → Electronic parts catalogue. |
