6.6.1 Connecting coolant pipelines to the indoor unit
Carry out the following steps to connect coolant pipelines to the indoor unit:
1. Determine the tube length and disconnect the tube using a tube cutter to the required
length.
2. Remove the burr on the cut edges.
3. Push the cap nut (which is screwed at the time of dispatch onto the connection nozzle of
the indoor unit) onto the tube end.
4. Flange the tube ends.
5. Align the tube and valve centrally and rst pull the cap nut by hand and then with a torque
wrench and an adjustable spanner to counter it. Maintain the correct torques (→ Permis-
sible tightening torques of the coolant pipelines - Combination hydro-module H-Genera-
