IMPORTANT MAINTENANCE INFORMATION
WARNING: the filter may only be removed from the sealed
box and fitted to the unit at the time it will be used for the
first time. The electrostatic charge when functioning nor-
mally runs out after around two years from the opening of
the sealed box. After this date the filter maintains its
mechanical function. You are advised to substitute a new
electrostatically pre-charged filter that you can find at our
assistance centres.
WARNING: The fancoil is connected to the power supply
and a water circuit. Operations performed by persons
without the required technical skills can lead to personal
injury to the operator or damage to the unit and surround-
ing objects.
POWER THE FANCOIL WITH SINGLE-PHASE 230 V ONLY
Use of other power supplies could cause permanent damage
to the fancoil.
NEVER USE THE FANCOIL FOR APPLICATIONS FOR WHICH
IT WAS NOT DESIGNED
Do not use the fancoil in husbandry applications (e.g. incuba-
tion).
AIR THE ROOM
Periodically air the room in which the fancoil 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 ADJUST THE TEMPERATURE
Room temperature should be regulated to ensure maximum
comfort to persons present, particularly in the case of the
elderly, infants and invalids. Prevent temperature fluctuations
between indoors and outdoors greater than 7 °C during sum-
mer.
Note that very low temperatures during summer will lead to
greater electricity consumption.
ORIENT AIR FLOW CORRECTLY
Air delivered by the fancoil should not be oriented directly at
people; even if air temperature is greater than room tempera-
ture, it can cause a cold sensation and consequently discom-
fort.
DO NOT USE HOT WATER
When cleaning the indoor unit, use rags or soft sponges
soaked in warm water (no higher than 40°C).
OPERATING LIMITS
Maximum water inlet temperature 80 °C
Maximum working pressure
The assembly site must be chosen in such a way that the
maximum and minimum ambient temperature limits are
respected 0÷45°C (<85% U.R.).
Minimum average water temperature
To prevent the formation of condensation on the exterior of
the unit while the fan is operating, the average water tempera-

-
Do not use chemical products or solvents to clean any part of
the fancoil.
Do not splash water on interior or exterior surfaces of the fan-
coil; danger of short circuit.
PERIODICALLY CLEAN THE FILTER
Frequent cleaning of the filter will ensure more efficient unit
operation.
Check whether the filter requires cleaning; if it is particularly
dirty, clean it more often.
Clean the filter frequently. Use a vacuum cleaner to remove
built up dust. Avoid water or detergents if possible since they
greatly accelerate loss of the filter's electrostatic charge.
After cleaning and drying the filter, fit it on the fancoil by fol-
lowing the removal procedure in reverse order.
SPECIAL CLEANING
The removable drip tray and fan volute ensure thorough clean-
ing of the unit (by specifically trained personnel), essential for
installations in venues subject to crowding or in those with
special hygiene requirements.
DURING UNIT OPERATION
Always leave the filter on the fancoil during operation (other-
wise dust in the air could soil the surface of the coil).
IT IS NORMAL
During cooling, water vapour may be present in the air deliv-
ery of the fan coil.
In the heating function it might be possible to hear a slight
hiss around the fan coil. Sometimes the fan coil might give off
unpleasant smells due to the accumulation of dirt in the air of
the environment (especially if the room is not ventilated regu-
larly, clean the filter more often).
During the operation, there could be noises and creaks inside
the device, due to the various heat expansions of the elements
(plastic and metallic), but this does not indicate any malfunc-
tioning and does not cause damage to the unit unless the
maximum input water temperature is exceeded.
WARNING
Avoid that the device is used by children or incompetent persons
without appropriate supervision; also note that the unit should
not be used by children as a game.
ture should not drop beneath the limits shown in the table
b e l o w, d e t e r m i n e d b y t h e a m b i e n t c o n d i t i o n s .
These limits refer to unit operation with fan at minimum
speed. Note that condensation may form on the exterior of the
unit if cold water circulates through the coil while the fan is off
for prolonged periods of time, so it is advisable to fit the
additional three-way valve.
