Unit installation

NOTICE
Incorrect assembly can cause material damage.
If the indoor unit is mounted incorrectly, it may drop off the ceiling.
▶ Only mount the indoor unit 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
▶ 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 ( Figs. 10 to 11).
▶ Define and mark the position of the suspension bolts on the ceiling or
wall.
▶ If necessary, break out the base or rear (Fig. 30) of the indoor unit at
the position marked accordingly.
▶ Drill wall or floor lead-through on a slope for piping.
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.
▶ Remove the side panels and air inlet grille ( Fig. 25).
▶ Hang the indoor unit on the ceiling using the suspension bolts with
the washers and nuts (ceiling-mounted installation  Fig. 26), or
secure it to the wall (floor-standing installation  Fig. 27).
▶ Align the indoor unit horizontally or vertically by turning the nuts on
the threaded rods.
NOTICE
If the indoor unit is suspended inclined or is not standing level,
condensate may leak out.
▶ Use a spirit level to align the indoor unit horizontally.
▶ For ceiling-mounted installation ensure a slope of approx. 1.5%
 Fig. 26.
▶ Secure the appliance at the correct installation position with lock
nuts.
▶ Establish pipe connections as described in chapter 3.5.

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. 15).
▶ Remove the cover for the pipe connections ( Fig. 19 and 20).
▶ Establish pipe connections as described in chapter 3.5.
3.4 Installing the outside air duct
There is an outside air intake opening on the appliance, which can be
used if required ( Fig. 30, [1]).
No more than 5% of the air volumetric flow rate can be introduced via the
outside air intake opening.

Pipework connection

3.5.1 Connecting refrigerant lines to the indoor and outdoor unit
CAUTION
Discharge of refrigerant due to leaky connections
Refrigerant may be discharged if pipe connections are incorrectly
installed. Reusable mechanical connections and flared connections are
not permitted indoors.
▶ Tighten flared connections only once.
▶ After releasing, always fabricate the flared connection again.
Copper pipes are available in metric and imperial sizes, the flare nut
thread is however the same. The flared fittings on the indoor and outdoor
unit are intended for imperial sizes.
▶ When using metric copper pipes, replace the flare nuts with nuts of a
suitable diameter ( Tab. 7).
▶ Determine pipe diameter and length ( Page 48).
▶ Cut the pipe to length using a pipe cutter ( Fig. 16).
▶ Deburr the inside of the pipe at both ends and tap to remove swarf.
▶ Insert the nut onto the pipe.
▶ Widen the pipe using a flaring tool to the size indicated in the tab. 7.
It must be possible to slide the nut up to the edge but not beyond it.
▶ Connect the pipe and tighten the screw fitting to the torque specified
in the tab. 7.
▶ Repeat the above steps for the other pipes.
NOTICE
Reduced efficiency due to heat transfer between refrigerant pipes
▶ Thermally insulate the refrigerant lines separately.
▶ Fit the insulation on the pipes and secure.
