The units are shipped in cardboard box standard packing and
polystirene shells.
PACKING
WARNING: The fancoil is connected
to the power supply and a water cir-
cuit. 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.
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.
POWER THE FANCOIL WITH SINGLE-
PHASE 230 V ONLY
Use of other power supplies could cause
permanent damage to the fancoil.

APPLICATIONS FOR WHICH IT WAS
NOT DESIGNED
Do not use the fancoil in husbandry
applications (e.g. incubation).
AIR THE ROOM
Periodically air the room in which the
fancoil has been installed; this is particu-
larly important if the room is occupied
by many people, or if gas appliances or
sources of odours are present.
C O R R E C T L Y A D J U S T T H E
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 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.
DURING UNIT OPERATION
Always leave the filter on the fancoil
during operation (otherwise 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 pos-
sible 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 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 tem-
perature is exceeded.
MAINTENANCE
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 sol-
vents to clean any part of the fancoil.
Do not splash water on interior or exte-
rior 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 clean-
ing; 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 elec-
trostatic 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), essen-
tial for installations in venues subject
to crowding or in those with special
hygiene requirements.
IMPORTANT INFORMATION AND MAINTENANCE
Maximum water inlet temperature
80 °C
Maximum working pressure
8 bar
OPERATING LIMITS
To prevent the formation of condensa-
tion on the exterior of the unit while
the fan 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. Note that con-
densation 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.
Consult the manual of the control panel for the installation and use
instructions.
