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 or the main drip tray in case of models
FWL and FWM;
■
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;
■ 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 or the main drip tray for the models FWL and
FWM;
■ 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, 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, provide for an inspection port to the unit.
In case of FWL, install the bottom plate according to figure 6.
FIELD WIRING
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.
Each unit requires a switch (IL) on the power supply with a distance
of at least 3 mm between the opening contacts and a suitable safety
fuse (F).
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.

TEST RUN
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.
USE
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.
All field wiring and components must be installed by a
licensed electrician and must comply with relevant local
and national regulations.
