INSTALLATION
CAUTION: before carrying out any work, put the proper
individual protection devices on.
CAUTION: before carrying out any work, make sure the
electrical power is unplugged.
CAUTION: electrical connections, the installation of the
fan coils and their accessories must only be carried out by
people with the proper technical and professional qualifi-
cations for the installation, conversion, expansion and
maintenance of the machinery and able to check that it is
working properly and safe.
In particular, the following checks are required for electri-
cal connections:
- Measurement of the electrical system insulation resistance.
- Continuity test of the protection wires.
Instructions essential for the proper installation of the equip-
ment are shown here.
The final touches to all the operations are however left to
the experience of the installation engineer in accordance
with the specific needs.
Do not install units in premises where there are inflamma-
ble gases or acid or alkaline substances that could irrepara-
bly damage the aluminium-copper heat exchanger or inter-
nal plastic parts.
Do not install the unit in workshops or kitchens where the
oil vapours mixed with the treated air can be deposited on
the exchange batteries, reducing their performance on the
parts inside the unit damaging the plastic parts.
Choose a position in the centre of the room if possible; the

OPERATION LIMITS

See TAB. 1.
The assembly area must chosen in such away that the
maximum and minimum ambient temperatures, Ta, is
respected 0°C < Ta < 45°C ; R.H. < 85%.
The ECA cassette conditioners are powered with 1 ~ 230
V 50 Hz current and grounding, the line tension must
anyway remain within a tolerance of ±10% of the rated
value.
If the conditioner is operating continuously in cooling mode
inside a room with high relative humidity, condensate may
form on the air delivery. This condensate may be deposited
on the floor and other objects underneath it.
Heating with heat pump could cause creaking because of
the various heat dilations of the elements (plastics and
metals), this however does not damage the unit.

regulation of the air output allows the air to be distributed
optimally in the room. Generally the best position of the fins
is that that allows the launch of the air adhering to the cei-
ling for the coined effect, during cold functioning. The side
section of the deflectors shows the opening positions for
proper warm functioning (opening 20°) and cold functio-
ning (opening 10°) of the machine. There are intermediate
and completely closed positions available. Thanks to the
special shapes of the fins the machine can also function
with the deflectors completely closed.
The regulation of the air output allows the air to be distribu-
ted optimally in the room.
Do not install at height of above three metres (fig. 9).
The FCA unit is set for connection with fresh air ducts and
for the delivery of the treated air in an adjacent room. The
KFA accessory, a metal flange 100 mm in diameter suitably
scaled to be attached to the polystyrene basin is available
for the link with the ducts. See the instructions supplied
with the accessory for installation instructions.
