It is possible to change the water connections side operating as
follows:
! remove the cover front panel of the basic unit (4 screws), in
case of models FWV and FWZ or the main drip tray in case of
models FWL, FWR, FWM and FWS;
! remove the heat exchanger cover (2 screws);
! remove the heat exchanger (4 screws) fixed on the side
panels of the basic unit;
! remove the lower partition plate;
! disconnect the motor cables from the terminal strip;
! remove the terminal strip and reassemble it on the opposite
side;
! take out the motor cable and place it on the opposite side;
remove the rubber snap bushing;
! remove the drain pipe and place it on the opposite side; set the
drain pipe in place of the closing cap of the drip tray and fix that
closing cap back in the position where the drain pipe originally
was;
! turn the heat exchanger 180° and insert it on the side panel
removing the pre-cut slots; fix it to the unit using the screws
supplied;
! reassemble the lower partition plate on the bottom side;
! reassemble the heat exchanger cover;
! reassemble the control panel opposite to the water
connections in case of model FWV and FWZ;
! insert the rubber snap bushing into the hole previously used
for the drain pipe, reassemble the cable fastener on the side
panel, and reassemble the cables connecting them to the
terminal strip;
! reassemble the cover front panel (4 screws) in case of models
FWV and FWZ or the main drip tray for the models FWL, FWR,
FWM and FWS;
! close the holes previously used with drip proof material.
Carry out the purge from the heat exchanger operating on the air vent
valves (10 hexagon wrench) located beside the water connections of
the heat exchanger.
In case of concealed models FWM and FWS, perform the connection
between the unit and the ducts, and place damping material between
the duct and the unit.
The ducts, in particular the outlet ones, must be insulated.
In order to avoid air back suction on the unit, keep a minimum distance
between the air outlet and recovered air flow as shown in figure 4.
The minimum installation height may not be lower than 1.8 m from the
floor level.
In case of FWM and FWS, provide for an inspection port to the unit.
The FWM and FWS built-in models must not be accessible
to the public.
In case of FWL and FWR, install the bottom plate according to figure 6.
For fan coils equipped with auxiliary electric heating
element, ensure that any combustible material is at least 30
cm away from the electric heating element.
The openable side doors must be fixed with screw, due to
lack of controls onboard the fan coil.

ield wiring
All field wiring and components must be installed by a
licensed electrician and must comply with relevant local and
national regulations.
Carry out the electrical wiring after having turned the power off. Refer
to figure 5. For options, refer to the appropriate manual.
Check that the power supply corresponds to the nominal power supply
stated on the unit nameplate.
An omnipolar mains isolator in overvoltage category III must be
present for every fan coil in the power supply line.
Power consumption is shown on the data plate fixed to the unit.
Make sure to carefully execute the wiring in function of the combination
unit/controller and this according to the correct wiring diagram
delivered with every accessory.

Check that the unit is perfectly levelled and that the drain pipe is not
obstructed (rubble deposits, etc.).
Check that the water connections (to the heat exchanger and water
drainage) are sealed.
Check that the electrical wiring is perfectly tight (perform this check
with voltage OFF).
Be sure that the air purge of the heat exchanger has been carried out
correctly.
Replace the cabinet (where existing).
Turn on the power supply and check the unit running.
U
se
To use the unit, refer to the instructions in the installation and operation
manual of the controller. Dedicated controllers are available as
accessory.
Air outlet grills can be swivelled 180° to direct the flow into the room or
towards the wall on which the unit is mounted.
The grills and the side doors are snapped onto the cabinet. Before
removing them in order to change their position, cut the power off and
wear protective gloves.
