Before installing the fan coil, ensure that:

- The air inlet and delivery are not obstructed.
- The hydraulic connections are positioned and dimensioned as
- The electric power supply line has the features requested on the
fan coil's data plate.
In normal operation, particularly with the fan at minimum speed and
ambient air with high relative humidity, condensation may form on
the air outlet and on some external parts of the unit. To avoid such
issues while always remaining within the operating limits envisaged
for the unit, it is necessary to limitthe (average) temperature of the
water inside the heat exchanger. In particular, the difference
between the air dew point (TA,DP) and the average water
temperature (TWM) must NOT exceed 14 °C, according to the
following relationship:
TW>TA,DP-14 °C
Example: in the case of ambient air at 25 ° C with 75% relative
humidity, the dew point temperature is about 20 ° C and therefore
the average temperature of the water
in the battery must be greater then:
-20-14 = 6 °C in order to avoid condensation on a fancoil equipped
with a valve.
- 20-12 = 8 °C If the valve kit accessory can not be installed.
In the event the indoor unit is stopped for a prolonged period, with
the fan stopped and circulation of cold water in the heat exchanger,
condensation may also form on the unit's exterior. In this case it is
advisable to install the 3-way (or 2-way) valve
is stopped.
Remove the cabinet, where existing, by unscrewing the 4 fastening
