5 INSTALLATION
WARNING: unit installation and start-up must be entrusted to competent
personnel and performed in a workmanlike manner, in accordance with
current regulations.
For each unit 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) .
WARNING: Install the unit, circuit breaker (IL) and/or any remote controls
in a place out of reach of persons who may be taking a bath or shower.
Remove the cabinet by taking out the fastening screws, accessible once
the doors have been lifted (figure 4).
WARNING: the cable connecting the microswitch is wired to the terminal
block and must be disconnected before the cabinet can be completely
disengaged from the base unit
When choosing an installation site, you should observe the following rules:
- The heating unit should not be placed immediately under a socket.
- Do not install the unit in places where inflammable gases or powders are
present;
- Do not expose the unit to sprays of water;
- Install the unit on walls able to withstand its weight. Keep a clear space
all around the unit to assure the proper functioning and accessibility for

FLAT S

INSTALLATION REQUIREMENTS

The fan coils should be installed in a position where the room can be cooled
or heated evenly, on walls or ceilings able to withstand their weight.
It is advisable to install any accessories on the standard unit prior to
positioning the latter.
For installation and use of accessories, please refer to the relative technical
sheets.
To guarantee the proper functioning of the unit and access for routine and
extraordinary maintenance purposes, it is necessary to comply with the
minimum installation clearance requirements (figure 1).
Install any remote control panel in an easily accessible position allowing the
user to set the functions while ensuring an accurate reading of the ambient
temperature, if provided . You should avoid:
- positions directly exposed to sunlight;
- positions exposed to direct currents of warm or cold air;
- placing obstacles that impede an accurate temperature reading.
During wintertime periods of quiescence, drain water from the system, to
prevent ice from forming. If anti-freeze solutions are used, check for their
freezing point using the table below.
Glycol by weight
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 S model (fig. 1).
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 5):
- remove the cabinet (figure 4)
- remove front duct (6 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 (6 screws)
- stop the unused holes with condensate proof material.
NOTE: the electrical wiring must always be positioned on the opposite
side of the plumbing connections.
