▶ Condensate that forms during operation must be able to drain off
easily. Lay a drain hose if required. In cold regions, installation of the
drain pipe is not advisable as freezing could result.
▶ Place the outdoor unit on a stable base.
Notes on the wired room controller
▶ The ambient temperature at the installation location should be in the
following range: −5...43 °C.
▶ The relative humidity at the installation location should be in the
following range: 40. 90 %.

Unit installation
NOTICE
Incorrect assembly can cause material damage.
If the appliance is mounted incorrectly, it may drop off the ceiling
▶ Only mount the appliance on a solid flat ceiling. The ceiling must be
able to carry the weight of the appliance.
▶ Only use screws and wall plugs that are suitable for the ceiling type
and appliance weight.
3.3.1
Installing the indoor unit
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 location, taking the minimum clearances
and orientation of the pipes into consideration (Fig. 5 to 4).
Make sure that the appliance fits between the structural ceiling and
suspended ceiling.
▶ The clearance between the built-in ducted indoor unit and drop
suspended 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 threaded rods in order to be able to
adjust the height precisely.
DANGER
Risk of injury!
At least two persons are required to hang the appliance and fasten it
securely.
▶ Do not install the appliance on your own.
▶ Hang the appliance on the suspension bolts with the washers and
nuts.
▶ Position the indoor unit at the correct height and align horizontally by
turning the nuts on the threaded rods.
NOTICE
If the appliance is not level condensate may leak out.
▶ Use a spirit level to align the appliance horizontally.
▶ Secure the appliance at the correct installation position with lock
nuts.

▶ Establish pipe connections as described in chapter 3.5.1.
3.3.2
Installing the outdoor unit
▶ Place the box so it is facing upwards.
▶ Cut and remove the packing straps.
▶ Pull the box up and off and remove the packaging.
▶ Prepare and install a floor or wall mounting bracket, depending on the
type of installation.
▶ Set up or hang the outdoor unit.
▶ When installing on the floor or wall mounting bracket, attach the
supplied drainage elbow and gasket ( Fig. 9).
▶ Remove the cover for the pipe connections ( Fig. 13 and 14).
▶ Establish pipe connections as described in chapter 3.5.1.

Air duct Installation
3.4.1
Installation of pipe and accessories
The appliance must be hung in order to install the pipes, etc.
If an air filter is not used, dust particles may accumulate in the heat
exchanger and cause malfunctions and leaks.
▶ To prevent the air discharged by the air conditioner from being drawn
back in directly: plan the air outlet and air inlet so that they are not too
close to one another.
▶ Before installing the air duct, make sure the static pressure of the air
duct is within the permitted range ( Tables 75 and figures 32
to 55).

Table 75 External static pressure
The external static pressure (SP1...4) can be set via the configuration
menu of the wired controller.
▶ Always incorporate isolators when connecting the air conduits to the
appliance in order to prevent the noise from the indoor unit being
transmitted to the ventilation pipes.
