The Refrigerant
 To realize the function of the air conditioner unit, a special refrigerant circulates in the system.
The refrigerant is the fluoride R32 = GWP (Global warming potential). This refrigerant is
flammable and inodorous. It can lead to explosions under certain conditions, however the
flammability of this refrigerant is very low and it can be ignited only by fire.
 Compared to other common refrigerants, R32 is a non-polluting refrigerant with no harm to
the ozonosphere and a lower effect upon the greenhouse effect. R32 has very good
thermodynamic features which lead to a really high energy efficiency. The units therefore
need less filling.

5. Disconnect the power supply before carrying out any work on the electrical circuit or carrying
out any safety work. For models with a plug, make sure the plug is easily accessible after
installation.
6. Do not connect the power before installation is complete.
7. Do not use the appliance if the power cable or plug are damaged. If the power cable is
damaged it must be replaced by the manufacturer, retailer or other qualified person to avoid a
hazard.
8. Since the temperature of the cooling circuit is high, keep the interconnecting cable away from
the copper pipe.
9. The unit must be installed in accordance with national wiring regulations.
10. Installation must only be performed by trained individuals in accordance with regulations.
The unit is charged with a slightly inflammable refrigerant, R32. Improper handling of this
gas may expose people and materials to serious damage. More details on this refrigerant are given
at the beginning of this manual.

INSTALLATION
Indoor unit installation
Step one: choose of indoor unit position
Decide where to install the unit based on room design, architectural limitations and customer
requirements. Check that in the selected location the unit can be accessed for servicing and cleaning
the filters. To install, use the installation plate as a template to identify the exact position for the wall
plugs and through-hole in the wall. The plastic casing has stoppers which if necessary can be
removed to route the refrigerant lines and cables. When operating in cool or dry mode, the moisture
in the air condenses on the coil of the indoor unit, collects in the basin and drains out through the
special rubber hose. The hose must be connected to a pipe with a suitable gradient, ensuring no
unnecessary bends are created. Do not run siphons and do not immerse in water.
Step two: mount the wall-installation plate
1. Position the installation plate on the wall. Use a level to position it horizontally and mark the holes
for the bolts on the wall.


V 11/17 51
2. Drill the holes for the screws in the wall with a hammer drill (the drill bit must match the plastic wall
plug). Then insert the wall plugs into the holes.
3. Secure the plate to the wall with the self-tapping screws (ST4.2X25TA). Check it is securely
attached by pulling on the bracket. If a plastic wall plug is loose, drill another hole nearby with the
hammer drill.
Step three: drill the hole for the piping
Select the position for the piping hole according to the direction of the outlet pipe. The piping hole
must be slightly lower than the wall-installation frame, as shown below.
09K -12K
Drill a piping hole of diameter 55 or 70 at the chosen location for the outlet pipe. To allow for
proper drainage, the piping hole in the wall must slant slightly downwards to the outdoor side, with a
gradient of 5 – 10°.
Piping hole Model
Ø 55 Cooling capacity < 6000 W
N.B.:
• Take the necessary safety measures when
drilling the hole and do not allow dust to
enter.
• The plastic wall plugs are not supplied but
must be purchased on site.
