3 - INSTALLATION OF THE UNITS
3.1 - INSTALLATION OF THE INDOOR UNIT
• It is preferable to handle the air handler without its cabinet, when installing it.
• If necessary, remove the fan assembly too.
3.1.1 - REMOVING THE CABINET
• Undo the 2 knurled screws (B) and the 2 tinsmith's screws (C).
• Remove the cabinet by lifting it slightly and pulling it forwards.
NOTE: To make the cabinet easier to handle, the outlet grille (1) and the inlet
grille (4) can be removed beforehand. To do this, undo the clips (A) by
turning them a quarter of a turn using a screwdriver or a coin.
IMPORTANT: When refitting the grilles, take care to lock the
clips (A) by turning them a quarter of a turn.
3.1.2 - REMOVING THE FAN ASSEMBLY
• Remove the fastening screws.
• Disconnect the loom at connector (D).
• Pull the fan assembly.
3.1.3 - CHOOSING THE LOCATION
AVOID:
• Putting the unit in very damp places. This unit is designed to be installed in sheltered
rooms (IP 20).
• Direct exposure to sunlight or the proximity of heat sources.
• Installing the unit behind curtains or furniture which could prevent air circulation.
• Installing the device near inflammable materials (as it can be equipped with an electric
heater).
MAKE SURE THAT:
• The position is the best one for providing good ventilation in the room.
• That the solidity of the support is adequate for the weight of the unit and does not cause
vibrations.
• The position chosen complies with the recommended minimum maintenance spaces
(see drawing opposite), and that the distance and difference in level between the units
are as small as possible.
• The piping and the electric connections are easily accessible.
