6.3 Creating a hole in the wall
ATTENTION
Danger of cables being chewed through by rodents in hollow walls
If wall holes exist in hollow walls, rodents could get in and chew through cables.
►
In order to prevent cables being chewed through, always use a wall grommet.
Carry out the following steps to make the wall hole:
1. Ensure that the selected installation location for the indoor and outdoor unit or for the
mono-bloc unit fulfils the installation criteria (→
5.2.2 Installation (bi-bloc systems), p. 100
→
5.2.3 Installation (mono-bloc systems), p. 109
).
2. Drill a wall hole of 70 mm diameter at the appropriate point. The hole must be made
according to the illustration (see below) with a slope of 5 to 7 mm towards the interior of the
room.
3. For hollow walls, always insert a suitable wall grommet or sleeve DN 70 (to be provided by
the customer) into the wall hole. You may have to cut the sleeve so that it projects on the
outside by about 15 mm.
4.
Seal the outer side using a suitable sealing compound (provided by the customer) after fitting
all cables.
