6.9.2 Cable feeds in the indoor unit
1. Remove the electrical box cover.
2. Route the cables from the cable inlets to the electric box:
– Feed the connecting cables over the cable glands on the back
through the corrugated hoses. Use an extension string. See figure
31 for the correct order of the hoses.
– Fix the cables with cable ties at the fixing points (Figure 32 [7]
and [9]). Avoid crossing the cables.
– The cable routing must be done in such a way that the cables don’t
touch hot surfaces like pipes or the booster heater.
3. Feed the cables into the electric box.
4. Connect the cables according to the chapters 6.9.3 – 6.9.4.
5. Reattach the cover of the electric box.
