Installation
▶ Insert the 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:
▶ Pull the underside of the casing down in the area of the two recesses
and pull the indoor unit forwards ( Fig. 17).
3.3.2 Installing the outdoor unit
▶ Place the box facing upwards.
▶ Cut and remove the packing straps.
▶ Pull the box up and off and remove the packaging.
▶ Prepare and mount a floor or wall mounting bracket, depending on
the type of installation.
▶ Mount or hang the outdoor unit using the anti-vibration coupling for
the feet which is supplied with the unit or is provided on site.
For the different outdoor unit sizes and the distance between their
mounting feet, see Chapter 2.6.1.
▶ When installing on the floor or wall mounting bracket, attach the
supplied drainage elbow and gasket at the bottom of the unit
( Fig. 18).
▶ Anchor the outdoor unit to the ground or to a wall-mounted bracket
with a bolt (M10). Consider the unit dimensions in Table 16.
▶ Remove the cover for the pipe connections ( Fig. 19).
▶ Establish pipe connections as described in Chapter 3.5.
▶ Mount the cover for the pipe connections again.
3.4 Piping wrapping
To avoid condensation and water leakage, the connecting pipe must be
wrapped with tape to ensure isolation from the air.

▶ Bundle the drain hose, refrigerant pipes, and signal cable.
While bundling these items together, do not intertwine or cross the
signal cable with any other wiring.
▶ Make sure that the drain hose is at the bottom of the bundle. Putting
the drain hose at the top of the bundle can cause the drain pan to
overflow, which can lead to fire or water damage.
▶ Using adhesive vinyl tape, attach the drain hose to the underside of
the refrigerant pipes.
▶ Using insulation tape, wrap the signal wire, refrigerant pipes, and
drain hose tightly together.
▶ Double-check that all items are bundled.

▶ When wrapping the bundle, keep the ends of the piping unwrapped.
You need to access them to test for leaks at the end of the installation
process.
3.5 Pipework connection
3.5.1 Connecting refrigerant lines to the indoor unit
WARNING
Risk of explosion and injury from presence of other gases or
substances.
The presence of other gases or substances will lower the unit's capacity,
and can cause abnormally high pressure in the refrigeration cycle.
▶ When connecting refrigerant piping, do not let substances or gases
other than the specified refrigerant enter the unit.
CAUTION
Discharge of refrigerant due to leaky connections
Refrigerant may be discharged if pipe connections are incorrectly
installed. Reusable mechanical connectors and flared joints are not
allowed indoors.
▶ Tighten flared connections only once.
▶ Always make new flared connections after loosening.
▶ Before the works are carried out, verify the correct refrigerant type.
The wrong refrigerant can lead to malfunction.
▶ Apart from the specified refrigerant, do not let air or other gases
enter the refrigeration circuit.
▶ If the refrigerant leaks during installation, make sure you fully
ventilate the room.
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
3
suitable diameter ( Tab. 9).
▶ Determine pipe diameter and length ( Page 62).
4
▶ Cut the pipe to length using a pipe cutter ( Fig. 13).
▶ Deburr the inside of the pipe at both ends and tap to remove swarf.
▶ Insert the nut onto the pipe.
0010052294-001
▶ Widen the pipe using a flaring tool to the size indicated in the tab. 9.
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. 9.
