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 normal-
ly 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 surrounding 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 discomfort.
DO NOT USE HOT WATER
When cleaning the indoor unit, use rags or soft sponges soaked
in warm water (no higher than 40°C).
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.
OPERATING LIMITS
Maximum water inlet temperature
Maximum working pressure 8 bar
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

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 follow-
ing 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 spe-
cial 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 delivery
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 maxi-
mum input water temperature is exceeded.
WARNING
Avoid that the device is used by children or incompetent persons
80 °C
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.
Note that condensation may form on the exterior of the unit if
cold water circulates through the coil while the fan is off for pro-
longed periods of time, so it is advisable to fit the additional
three-way valve.
