IMPORTANT INFORMATION
WARNING: The fan coil unit is connected to the power
supply and a water circuit. Operations performed by per-
sons without the required technical skills can lead to
personal injury to the operator or damage to the unit and
surrounding objects.
MALFUNCTION
In the case of a malfunction remove power to the unit
then reapply it and start the unit again. If the problem
occurs again, call your area After-Sales service department
promptly.
POWER THE FAN COIL UNIT ONLY WITH 230 VOLT, SIN-
GLE PHASE, 50 Hz
Use of other power supplies could cause permanent damage
to the fan coil unit.
USE THE (TLW2) REMOTE CONTROL OR THE WIRED
CONTROL PANEL (PFW2) TO TURN THE FAN COIL UNIT
ON AND OFF
Do not turn the fan coil unit on or off using the auxiliary
switch except in an emergency.
DO NOT PULL THE ELECTRICAL CABLE
It is very dangerous to pull, tread on or crush the electrical
power cable or fix it with nails or drawing pins.
A damaged power cable can cause short circuits and per-
sonal injury.
DO NOT PUT ANYTHING IN THE AIR OUTLETS
Do not put anything at all in the air outlet slots.
This could cause injury to people and damage to the fan.
DO NOT USE THE FAN COIL UNIT IMPROPERLY
Do not use the fan coil unit in animal husbandry applica-
tions.
VENTILATING THE ROOM
Periodically air the room in which the fan coil unit has
been installed; this is particularly important if the room is
occupied by many people, or if gas appliances or sources of
odours are present.
CORRECTLY CONTROLLING THE TEMPERATURE
The room temperature should be controlled in order to
provide maximum comfort to the people in the room,
especially if they are elderly, children or ill, avoiding sud-
den changes in temperature between the outside and inside
above 7 °C in summer.
Careful choice of the room temperature will lead to energy
savings.
CORRECTLY ADJUSTING THE AIR JET
The air coming out of the fan coil unit must not strike people
directly; in fact, even if at a temperature that is higher than
the room temperature, it could cause a cold sensation and
resulting discomfort.
Only adjust the vertical blades by hand.
In the versions with microprocessor controller adjust the
horizontal blade with the LOUVRE or SWING key of the
remote control or the wired control panel.
In the versions without microprocessor controller adjust the
horizontal blades by hand.
DURING OPERATION
Always leave the filter in the fan coil unit during operation
otherwise dust in the air will dirty the surfaces of the coil.
WHAT IS NORMAL
During cooling, water vapour may be present in the air dis-
charge.
During heating it might be possible to hear a slight hiss
around the fan coil unit. Sometimes the fan coil unit might
give off unpleasant smells due to the accumulation of sub-
stances from the air of the room (especially if the room is
not ventilated regularly. Clean the filter more often).
During operation, there could be noises and creaks inside
the device, due to the thermal expansion of the various
components (plastic and metallic), but this does not indicate
a malfunction and does not cause damage to the unit unless
the maximum input water temperature is exceeded.

Minimum average water temperature
To prevent the formation of condensation on the exterior
of the unit while the fan coil unit is operating, the average
water temperature should not drop beneath the limits shown
in the table below, determined by the ambient conditions.
These limits refer to unit operation with fan at minimum
speed.
Flow rate limits:
MODEL FCW 21 31 41
Minimum flow rate [l/h] 100 100 150
Maximum flow rate [l/h] 750 750 1100
OPERATIONAL LIMITS
The installation site must be chosen in such a way that the
maximum and minimum room temperature limits, Ta, are
respected: 0°C < Ta < 40°C ; R.H. < 85%.
Connect to a 230 V ~ 50 Hz power supply and earth
connection, and ensure it remains within the limit of ±10%
with respect to the nominal value.
