Mount electronic cooling unit valve group
Insert new little gasket ring into screwed nipple
Insert 2 black O-rings on back of flange of the electronic cooling unit valve group
Screw in electronic cooling unit valve group by hand at upper and lower joints
Make sure the that the 2 O-rings on back of the flange stay in position!
Attach flange
- 6 mm hexagon spanner with ball head + extension
Mount flange with torque spanner
- 6 mm hexagon spanner with ball head + extension
- Torque spanner
- Tightening torque: 23 Nm
Risk of damage to the component.
Tighten screws crosswise in at least 2 steps to the prescribed tightening torque.
