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.
3.1.4 - MOUNTING
• The system can be placed on the floor or fixed to the wall or ceiling.
• It
must be
fitted flush against a wall in all cases.
• For wall or ceiling mounting, refer to the Accessories section for the supports
which can be used.
3.1.5 - CHOOSING THE BLOWING DIRECTION
A - STANDARD DELIVERY
• Vertical backward blowing.
B - FORWARD BLOWING:
