Choosing the installation site
Positions to avoid: Exposure to direct sunlight. Areas close to heat sources. On damp walls or in positions that may be exposed to water hazard. Where curtains or furniture may obstruct free air circulation.
Recommendations: Choose an area free from obstructions which may cause uneven air distribution and/or return. Consider using an area where installation is easy. Choose a position that allows for the clearances required. Look for a position in the room which ensures the best possible air distribution. Install unit in a position where condensate can easily be piped to an appropriate drain.

Max. 2 louvres closed
Heat pump: louvre position for correct air flow Cooling: louvre position for correct air flow
Install the unit as centrally as possible in the room, the air flow direction can be controlled by means of the remote control (where used) or automatically, according to the operating mode (cooling or heating): this will ensure optimum distribution of the air in the room. During cooling mode operation the best position for the deflecting louvres is one which allows air diffusion close to the ceiling (Coanda effect). In heating mode, the louvres should be positioned so that the air is directed towards the floor, in order to prevent layers of hot air forming in the upper part of the room (this will happen automatically when the deflecting louvres are positioned in the AUTOMATIC mode). Alternatively the louvres can be placed in intermediate positions (with infrared control only) or allowed to move continuously (SWING).
In order to allow easy and rapid installation and maintenance, make sure that in the selected position it is possible to remove the ceiling panels or, if the ceiling is constructed using masonry, that access to the unit is guaranteed.
ATTENTION: Only restrict the air outlets as indicated in the drawing.
WARNING: To close one or two air outlets use the special kit.
GB - 6
Prior to installation
Threaded hangers "T" bar (to be removed)
It is advisable to place the unit as close as possible to the installation site before removing it from the packaging. The grille panel and the remote control are separately packed for maximum protection. IMPORTANT: Do not lift the unit by the condensate drain discharge pipe or by the refrigerant connections; hold it by its four corners only. Unit installation will be facilitated using a stacker. If plaster board ceiling panels are installed the maximum dimensions of the unit housing must not exceed 660 x 660 mm (for models 12-18-24) and 900 x 900 mm (for models 28-36-48-60). In rooms with high humidity, brackets should be insulated using the self adhesive insulation supplied.
First position the refrigerant lines, as described in the chapter Refrigerant connections. Remove the T bar in order to facilitate installation operations.
Carefully lift the unit (without the frame) using the four suspension brackets (or the four corners), inserting it into the false ceiling. If the T bar cannot be removed the unit may need to be tilted (this operation may only be carried out with false ceilings with a minimum height of 300 mm).
Mark the position of the hangers, refrigerant lines and condensate drain pipe, power supply cables and remote control cable (see dimensions); the cardboard template (supplied with the kit) may be of assistance for this operation. Depending on the type of ceiling the hangers can be fixed as shown in the drawing.
False ceiling Spirit level
Nut Wooden frame Threaded hangers Washers Nut
Washer Threaded hangers Washer Nut Nut
Once the threaded hangers have been positioned, do not tighten the nuts, and insert the washers as shown in the drawing.
Align and level the unit by adjusting the nuts and locknuts on the threaded hangers, maintaining a distance of 25 - 30 mm between the sheet metal body and the underside of the false ceiling. Reposition the T bar and align the unit in relation to the bar by tightening the nuts and locknuts. After connection of the condensate drain line and the refrigerant lines, carry out a final check to make sure that the unit is level.
GB - 7
Frame support brackets
Making the hole for connection pipes in the external wall After positioning the units and determining the connection position, make a 70 mm hole in the wall. The same hole can be used as a condensate drain pipe conduit. The hole should have a 5 - 10 mm slope toward the outside. Insert the plastic conduit provided. Pass the power connection cables through the conduit (see electrical connections).
Installation of grille/frame assembly Carefully unpack the assembly and check for damage sustained in transport. Attach the assembly to the unit by using the two hooks.
Flaring the end of pipes
Pipe Pipe insulation Adhesive tape
Remove the protection caps from the copper pipe ends. Holding the tube downward, cut the extreme end off, removing any copper shavings with a deburring blade. Remove the flare nuts from the FLARE connection body of the indoor unit and insert them into the pipes. Make the flare to the pipe end with the proper flaring tool.
Once all connections have been completed, check for leaks using soapy water. Finally, wrap connections with anti-condensate insulation and tighten with tape, without exerting excessive pressure on the insulation. Repair and cover any possible cracks in the insulation.
Extra charge of refrigerant (for R-410A only)
With pipe lengths up to 8 metres, the models shown below need an extra charge of refrigerant (R-410A). For longer pipes, refer to the outdoor unit installation manual.
Indoor unit model Outdoor unit model Pipe lengths up to 8 m 40KMC024N 40KMC124EN 38GL024G 70 g 40KMC018N 40KMC118EN 38YY018G 110 g
Flare end must not have any burrs or imperfections. The length of the flared walls must be uniform.
Lubricate the end of pipe and the thread of the flare connection with anti-freeze oil. Tighten by hand and then use two wrenches to tighten all connections fully, applying the tightening torque shown in the table.
Pour several litres of water into the condensate drain pan and check that it flows freely to the drain. Check pipe gradient and look for possible obstructions.

Side knockouts allow connection of fresh air inlet ducts and ducts to deliver conditioned air to an adjacent room. Remove the external prepunched anti-condensate insulation and take away the knockout panels using a punch.
Use locally purchased material, suitable for operating temperatures of 60 C (continuous). Conduits can be of flexible polyester (with spiral core) or corrugated aluminium, externally covered with anti-condensate material (fibre glass from 12 to 25 mm thickness). To complete the installation, all non-insulated ducts must be covered with anti-condensate insulation (ex. expanded neoprene, 6 mm thickness). Not observing of these instructions may cause condensate dripping; the manufacturer will not be held responsible for any damage caused. The two prepunched side knockouts must not be used at the same time to deliver conditioned air to an adjacent room. The return and supply duct lengths can be calculated in accordance with the air distribution to an adjacent room and fresh air renewal diagrams (also taking into account the pressure drop through air diffusers, grilles and fresh air filters), as well as the increase in noise caused by these ducts.
Air distribution to adjacent room With a pencil, trace a line on the polystyrene around the inside edges of the panel that was previously removed. Cut away the polystyrene with a knife, taking care not to damage the heat exchange coil.
Fresh air intake Remove the polystyrene partition. Introduce baffle supplied after frame has been hooked as per above figure. Following that screw the frame/grille assembly using the 4 screws.

Supply air duct to adjacent room
In case of two louvres closed, the fresh air flow towards the adjacent room is 50% higher compared with only one louvre closed (with equal static external pressure).
Fresh air renewal
The supplementary fan motor for outside air intake has to be supplied separately and controlled by a bipolar ON-OFF switch with safety fuses (field-installed). To adjust the fan motor air flow to the required values it is advisable to install a speed controller. Fresh air flow must be less than 10% of the total air flow, to avoid operating problems. For fresh air ventilation rates higher than 10%, a primary air treatment system with separate deflectors is recommended. Install an air inlet grille with filter inspection port to prevent dust and dirt from entering and fouling the indoor unit heat exchanger. Filter installation also makes the installation of a duct closing damper during shutdown periods unnecessary.
Conditioned air supply to an adjacent room
Air supply to an adjacent room requires that the outlet corresponding with the duct is closed, using the air supply outlet obstruction kit supplied. The kit cannot be used in units equipped with electric heater. An air inlet grille must be fitted (if possible near the floor) between the air conditioned room (where the unit is situated) and the adjacent room or, alternatively, the door must be undercut, as shown in the drawing. The duct lengths can be calculated in accordance with the air distribution to an adjacent room diagram, also taking into account the pressure drop through air diffusers and fresh air filters. DO NOT use active carbon or electrostatic filter kits for ducts towards adjacent rooms.

Information concerning indoor unit operation, timer status and diagnostic is given by 3 LEDs located on the unit. THE GREEN LED (P) shows the following conditions: - Fault codes (diagnostic); - During normal operation, the LED is lit. Once a failure occurs, the LED flashes at intervals of 0.5 seconds. The fault code is deduced from the number of times the LED flashes. Between one flash cycle and the next a pause of 5 seconds elapses. THE RED LED (Q) gives the following information: - During normal operation, the LED is OFF; - During defrost the LED is lit; - During the test for wired connection, the LED flashes at 0.1 second intervals. THE YELLOW LED (R) shows the operation in timer mode. During this operation the LED is lit. If the timer mode is active and the unit is immediately restarted after a stop, this LED flashes until a new signal is sent to the unit. In case the Room Controller is not working, obtain a qualified service personnel.
Once a failure occurs with the indoor unit in operation, the green unit LED flashes at intervals of 0.5 seconds. The fault code is deduced from the number of times the green LED flashes, blocking unit operation. Between one flash cycle and the next one, a pause of 5 seconds elapses.
