Creating a hole in the wall
CAUTION
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
compact device fulfils the installation criteria
→ 5.2.3 Setting up the Compact system, p.
2. Drill a wall hole of 70 mm diameter at the appropriate point. The hole must be made ac-
cording to the illustration (see above) 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.

Setting up devices
CAUTION
Danger of injury due to carrying of heavy loads
As the devices are very heavy, overloading poses a danger of injury while lifting and carrying
them.
► Always have the devices lifted and carried by more than one person and plan a suffi-
cient number of persons for the installation.
► For very high loads, use a suitable hoist.

Hydro-modules
Carry out the following steps to install the hydro-module:
1. Exercise caution as you unpack the hydro-module at the installation site.
2. Attach the two mounting plates contained in the scope of delivery on the wall as shown
in the illustration (above). For this, use six M8 hexagon screws, washers and dowels with
threaded insert (all to be provided on site). Ensure horizontal alignment (use spirit level).
Maintain the minimum distances from the wall and floor entered in the corresponding
illustration.
3. Have the hydro-module lifted by two persons and suspend the hydro-module by the slots
on its rear side, engaging them in the hooks of the top mounting plate. Ensure that the
hooks engage properly by moving them left and right.
4. In addition, attach the hydro-module by using three Phillips head screws on the bottom
