INSTALLATION
FLAT unit can be installed vertically (wall/floor) or horizontally (ceiling). And
namely:
FLAT L wall installation (100 mm from floor)
FLAT U vertical floor installation or horizontal ceiling installation
Fasten the base unit to the wall using the 4 slots provided and the screw anchors
suitable for the characteristics of the supporting wall, keeping the bottom edge
at least 100 mm above the floor to ensure a correct intake of air and facilitate
the filter removal in the case of FLAT L model.
In case of ceiling installation check that the installation height does not exceed
the maximum value specified on the table, in order to avoid hot air stratification
in the upper part of the room.
The height specified in the table are referred to the maximum operating speed.

The water connections are on the left side, viewing the unit from the front.
The exchanger connections can be switched over to the opposite side by
carrying out the following steps (figure 7):
- Remove the cabinet (figure 6);
- Remove front duct (4 screws)
- Remove the heat exchanger (4 screws) mounted on the base unit side panels
- remove the lower partition;
- disconnect the motor cables from the terminal board
- remove the terminal board and mount it on the opposite side panel
- Pull the motor cable and guide it to the opposite side; remove the plastic
cable bushing;
- Detach the condensate drainage hose and reattach it on the opposite side;
switch over the position of the drop-stop hose and the cap on the drip tray;
- Turn the heat exchanger by 180°;
- Replace the partition on the bottom part;
- Insert the connections in the proper slots on the right side panel; fasten them
to the base unit with proper screws;
- Insert the plastic cable bushing in the hole that was previously occupied
by condensate drainage hose, replace the cable holder on the side panel,
insert the cables and connect them to the terminal board.
- Replace front duct (4 screws)
- Stop the unused holes with condensate proof material.
Cable guide
NOTE: the electrical wiring must always be positioned on the opposite side
of the plumbing connections.
Make the plumbing connections to the heat exchanger and, where the cooling
function is to be used, to the condensate drainage outlet.
In case of ceiling mounting, in particular when the BH accessory is present,
install the unit with a slight slope, in order to facilitate the condensate drainage.
Before switching the unit on, check that it is installed in such a way as to
guarantee the required inclination for proper condensate drainage. Warning: Do
not use thick pipes or pipes whose characteristics (i.e. corrugated conduits)
may impede the condensate flow.
It is recommended to connect the installation intake to the bottom part of the
heat exchanger and the return to the upper part of it.
Bleed air from the exchanger by means of the air vent valves (hexagonal wrench
type 10) situated beside the plumbing connections of the exchanger.
To favour the drainage of condensate, the drain hose should be inclined
downward, at least 3 cm/m; make sure that no loops or bends form along its
path.
ELECTRICAL CONNECTIONS
Make the electrical connections with the power supply disconnected, in
accordance with current safety regulations, and following the wiring
diagrams in figure 8 and pertinent legend.
Check that the mains electricity supply is compatible with the voltage shown
on the unit rating plate.
The electrical connections indicated must be made by the installer.
For each fan coil an (
IL
) switch should be mounted on the power supply, with
opening contacts at a distance of at least 3 mm and a suitable protection fuse
(
F
).
In the wiring diagrams the following abbreviations are used:
1
Control panel connection (accessory)
BK
Black = High speed
BU
Blue = Medium speed
CN
Fast-on connector
F
Safety fuse - not supplied
IL
Circuit breaker - not supplied
M
Motor
MS
Air outlet FLAP w/microswitch
RD
Red = Low speed
WH
White =common
On completing installation, before applying the cabinet on the base unit,
connect the cable of the microswitch to the terminal block.
Replace the cabinet. As regards FLAT U model fasten the front panel by means
of the 2 screws supplied (figure 2). As regards FLAT U model install the lower
covering panel made of galvanised steel sheet in order to assure that air is
completely sucked from the grilles equipped with filter (figure 2).
At the end of the installation procedure, fit the air filter on the inlet and fix it in
place using the central screw provided (using a Phillips screwdriver, max length
8 cm).

FUNCTIONAL CHECK
- Check that the unit is properly levelled and that the drainage outlet is not
clogged (by masonry debris, etc.)
- Check that the unit is installed in such a way as to guarantee the proper air
flow.
- Check the tightness of the plumbing connections (to the exchanger and
condensate drainage line).
- Make sure the electric wires are tightly connected (carry out this check with
the power supply OFF).
- Make sure that air has been eliminated from the heat exchanger.
- Reapply the cabinet.
- Power the fan coil and check its performance.
