Installing the indoor unit on the wall

▶ Open the box at the top and lift the indoor unit out and up.
▶ Place the indoor unit with the moulded parts of the packaging face
down ( Fig. 15).
▶ Undo screw and remove the mounting plate on the rear of the indoor
unit.
▶ Determine the installation site, taking the minimum clearances into
consideration ( Fig. 14).
▶ Attach the mounting plate with a screw and wall plug centrally and at
the top of the wall and level out ( Fig. 16).
▶ Fasten the mounting plate with a further four screws and wall plugs so
that the mounting plate lies flat on the wall.
▶ Drill wall outlet for the piping (wall outlet should be behind the indoor
unit as a recommendation  Fig. 17).
▶ Change the position of the condensate pipe if necessary
( Fig. 19).
The pipe fittings on the indoor unit are generally located behind the
indoor unit. We recommend extending the pipes before mounting the
indoor unit.
▶ Establish pipe connections as described in Chapter 3.5.1.
▶ Bend the piping in the required direction if necessary, and knock out
an opening on the side of the indoor unit ( Fig. 21).
▶ Route the piping through the wall and attach the indoor unit to the
mounting plate ( Fig. 22).
▶ Fold up the top cover and remove one of the two filter elements
( Fig. 23).
▶ Insert the cold catalyst filter which is included in the scope of delivery
into the filter element, and mount the filter element again.
If it is necessary to take the indoor unit off the mounting plate:

Installing the indoor unit in the ceiling

We recommend preparing the pipes before hanging the indoor unit so
that only the pipes need to be connected.
▶ Open the box at the top and lift the indoor unit out and up.
▶ Determine the installation site, taking the minimum clearances and
orientation of the pipes into consideration:
– Cassette indoor units: Fig. 31 to 29
– Built-in ducted indoor units: Fig. 39 to 40
Make sure that the appliance fits between the structural ceiling and drop
ceiling.
▶ In the case of the cassette indoor unit, the fascia must be flush with
the drop ceiling.
▶ The clearance between the built-in ducted indoor unit and drop
ceiling must be at least 24 mm.
▶ Define and mark the position of the suspension bolts on the ceiling.
DANGER
Risk of injury!
The ceiling attachment must be suitable for carrying the weight of the
indoor unit. We recommend using M10 threaded rods in order to be able
to adjust the height precisely. Suitable nuts and washers are included in
the scope of delivery of the indoor unit.
DANGER
Risk of injury!
At least two persons are required to hang the unit and fasten it securely.
▶ Do not install the unit on your own.
▶ Hang the unit on the suspension bolts with the washers and nuts
included in the scope of delivery.
▶ Position the indoor unit at the correct height and align horizontally by
turning the nuts on the threaded rods.
NOTICE
If the unit is not level condensate may leak out.
▶ Use a spirit level to align the unit horizontally.
▶ Secure the unit at the correct installation position with lock nuts.
▶ Establish pipe connections as described in Chapter 3.5.1.
