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 with-
out 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. incu-
bation).
AIR THE ROOM
Periodically air the room in which the fancoil has been
installed; this is particularly important if the room is occu-
pied 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 fluctua-
tions between indoors and outdoors greater than 7 °C during
summer.
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 tem-
perature, 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).

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 tem-

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
fancoil; 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
following the removal procedure in reverse order.
SPECIAL CLEANING
The removable drip tray and fan volute ensure thorough
cleaning 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 (oth-
erwise 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 ventilat-
ed regularly, 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 malfunctioning 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.
perature 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 prolonged periods of time, so it is advisable to
fit the additional three-way valve.
