INSTALLATION

Remove control panel frame using the two snapped-on springs and then the
cabinet by unscrewing the 4 fastening screws reachable through the lifted side
doors (figure 3, page 19).
Install the bearing unit onto the wall using the 4 mounting slots and the supplied
anchor screw, keeping the unit at least 100 mm above the floor for a proper air
suction and an easy pulling out of the filter.
Carry out the hydraulic connections to the heat exchanger and in case of cooling
operation, to the water drainage system.
We suggest to provide for the water inlet from the upper side of the heat-exchanger
and the outlet on the bottom side for optimum use of the heat exchanger and to
obtain proper back flow heat exchange.
For a better water drainage lean the drain pipe downwards at least 3 cm/m
avoiding loops or narrowing on its way.
Purge the air from the heat-exchanger using the air vent valve located beside the
upper heat-exchanger connection.
Carry out the electrical wiring after having turned the power off in compliance
with the current safety regulations following the diagram of figure 4 page 19.
Check that the power supply corresponds to the rated power reported on the unit
nameplate.
Electric connections in dotted lines should be carried out by the installer.
Each fan coil should have a single socket and a switch (IL) with suitable fuse (F).
On the wiring diagrams the following abbreviations are used:
BK Black = max. speed
BU Blue = medium speed
CC Incorporated selection switch
F Fuse, not supplied
IL Line switch, not supplied
M Motor
RD Red = min. speed
TC Fan stop thermostat (accessory)
WH White = common
6 TEST RUN
- Check that the unit is perfectly levelled and that the drain pipe is not obstructed
(rubble deposits, etc.) in order to permit proper water drainage and air vent from
the heat-exchanger.
- Check that the water connections (to the heat-exchanger and water drainage)
are sealed.
- Check that the electrical wiring is perfectly tight.
- Be sure that the air purge of the heat-exchanger has been carried out.
Replace the cabinet. Check that the aligning spacer hooks are correctly fitted into
the slots of the cabinet (figure 5, page 19).
Replace the control panel frame.
Turn on the power supply and check the unit running.
The air outlet grills can be swivelled 180° to direct the flow into the room or
towards the wall behind the unit.
The unit is supplied with the outlet grills directing the air behind.
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.
7 USE
