INSTALLATION OF THE UNIT
WARNING: before carrying out any
work ensure the individual has the
appropriate personal protection.
WARNING: check that the power sup-
ply is disconnected before performing
operations on the unit.
WARNING: wiring connections,
installation of the fan coil unit and rel-
evant accessories should be performed
by a technician who has the necessary
technical and professional expertise to
install, modify, extend and maintain
systems and who is able to check the
system for the purposes of safety and

correct operation.
In the specific case of electrical
connections, the following must be
checked:
- Measurement of the electrical system
insulation resistance.
- Continuity test of the protective wir-
ing.
If the fan coil unit operates continu-
ously in cooling mode in a room with
high relative humidity, condensate
might form on the air discharge. This
condensate might be deposited on the
floor and on any objects underneath.

To prevent the formation of condensa-
tion on the exterior of the unit while
the fan is operating, the average water
temperature should not drop below the
operating limits shown in the manual
determined by the room temperature
and humidity conditions. These limits
refer to unit operation with fan at mini-
mum speed.
In order to avoid air stratification and
therefore achieve better mixing it is
advised not supply the fan coil unit
with water hotter than 65°C. The use
of very hot water could cause creak-
