INSTALLATION

WARNING:
It is mandatory to install the 3-way (or 2-way)
valve accessory in order to avoid the circulation of cold
water in the exchanger if the unit is not operated for
long periods of time, with the fan off. Install the auxiliary
water drip tray, provided together with the base unit, in
order to prevent valve kits from dripping.
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:
before carrying out any operation, check that
the voltage and frequency of the unit correspond exactly
to those of the main power supply.
WARNING:
Install the unit, circuit breaker (IL) and/or any re-
mote controls in a place out of reach of persons who may be
taking a bath or shower.
WARNING:
the EMC filters connected to frequency

INSTALLATION REQUIREMENTS

The fan coils should be installed in a position where the room
can be heated or cooled evenly, on ceilings able to support their
weight. Store the unit in its packaging until you are ready to in-
stall it.
For installation and use of accessories, please refer to the relative
technical sheets.
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.
Avoid therefore:
Ū positions directly exposed to sunlight;
Ū positions exposed to direct currents of warm or cold air
Ū placing obstacles that impede an accurate temperature
reading
NB:
The water sensor, where present, must be mounted in
the appropriate trap on the valve kit, on the INLET pipe.

Ū If a valve kit other than the one suggested is used, it is neces-
sary to install the sensor on the INLET pipe, by means of the
special copper socket filled with conductive paste.
Ū Lastly, the sensor must be properly isolated to ensure that it
reads the water temperature correctly.
NB:
The air and humidity sensors, where present, must be at-
tached in the appropriate section located in the intake area
of the base unit.

converters (inverters) can create leakage currents toward
ground (in order to make the unit EMC compliant, by re-
ducing conducted emissions on power supply line). De-
pending on installation site, this can force the cut out of the
differential safety switch. It is recommended to install a sepa-
rate differential safety switch, only for the BLDC unit, with an
adjustable threshold for the cut out current.
WARNING: keep the unit's grille in its original packaging
until final assembly.
RECOMMENDED:
neous air temperature in the room), it is recommended not
to exceed a heat exchanger water inlet temperature of 55 °C.
WARNING: during a shutdown for installation, in the event
of a connection to a fresh air intake or an ambient tempera-
ture close to 0 °C, there is a risk of the pipes freezing. Provide
drainage for the water circuit.

Make the plumbing connections to the heat exchanger and,
where the cooling function is to be used, to the condensate
drainage outlet.
WARNING:
In normal operation, particularly with the fan at minimum
speed and ambient air with high relative humidity, conden-
sation may form on the air outlet and on some external parts
of the unit.

To avoid such issues while always remaining within the oper-
ating limits envisaged for the unit, it is necessary to limit the
inlet temperature of the water inside the heat exchanger. In
particular, the difference between the air dew point (T
and the inlet water temperature (T
°C, according to the following relationship: TW>TA,DP-14
°C
Example: in the case of ambient air at 25 ° C with 75% rela-
tive humidity, the dew point temperature is about 20 ° C and
therefore the inlet temperature of the water in the battery
must be greater then:
Ū 20-14 = 6 °C in order to avoid condensation on a fancoil
equipped with a valve.
