• 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).

• 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.
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 (ref. h).
Following that screw the frame/grille assembly using the 4 screws.
k l m
• 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.

ENGLISH
➀ 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.
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 (mod. 40GKX1..W).
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.
• 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.
• 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.

Control configuration and operating test
Remote control configuration
Once the electrical connections have been completed, enter
the system configuration.
Check the correct positioning of the switch (see “Electrical
connections”).
Incorrect switch positioning will cause serious damage to the
system.
Remote control configuration with cable connection has to be
made following the instructions contained in the respective
manuals.
To configure the control proceed as follows:
• Place batteries in the remote control, observing the polarity
direction indicated.
• Energise the system by switching the main switch in the ON
position.
• Press the button for the selection of the operating mode
together with the button for the clock time adjustment for at least
two seconds (the latter is recessed and located next to the battery
compartment, use a pointed tool to activate).
• The remote control readout will display the letters “ld:un”.
• If the remote control readout displays the letters “CA:P” or
“Ad:dr”, press button
• Using the temperature adjustment buttons
number “3”.
• To send the message to the unit, press the start button
least two seconds, followed by the fan speed selection button
• The remote control will automatically switch off, thereby
completing the configuration.
For information on the remote control refer to the operation
and maintenance manual.

• Position the operating switch, located in the electrical board inside
the unit, to “Test”.
The installer must check that conditions 1, 2 have been fulfilled.
1) The air conditioner will start immediately (without the time delay
protection against frequent compressor cycling) in the cooling
mode without thermostatic control of the room temperature.
2) The red indicator on the unit will illuminate.
• Slide the switch under the unit panel from the “Test” to the
“Normal” position to exit from the test program.
• During the test program, any signal sent to the unit by the remote
control will stop the test.
