EXTRAORDINARY MAINTENANCE
Extraordinary maintenance must only be car-
ried out by Aermec After Sales Service centres,
or by technicians with the technical and profes-
sional requisites for the installation, transfor-
mation, amplification and maintenance of the
systems, and able to check these aspects in
terms of safety and good working. For the elec-
trical wiring in particular, checks relating to the
following aspects are required:
• Measurement of the electrical system insula-
tion strength.
• Continuity of the protection wires.
• Extraordinary maintenance consists of a set
of complex operations that involve the dis-
28.

OPERATION

• COOLING MODE

If the ambient sensor detects that the tempera-
ture is too warm, check the floor sensor. If the
floor temperature is lower than the ambient
temperature, the damper is modulated to allow
ambient air conditioning. The damper is suf-
ficiently modulated to compensate heat gain.
• AIR RECIRCULATION OPERATION
When the sensor detects a room with the local
temperature corresponding to the set point,
the damper is closed and the unit goes into
recirculation mode. An adjustable damper vent
allows for sufficient air recirculation to maintain
the required amount of fresh air.

• HEATING MODE

If the ambient sensor detects that the tem-
perature is too cold, check the floor sensor. If
the floor temperature is higher than the air
temperature, the damper is modulated, opening
to allow heating of the room. The damper is
modulated sufficiently to compensate for a loss
of heat.
mantling of the air treatment unit or its com-
ponents, resulting in the restoration of the
fan coil's functioning at maximum efficiency.
Before carrying out any work, make sure
the electricity supply is unplugged.
INTERVENTIONS:
• Internal cleaning, once a year or before the
machine is shut down for a long period. In
rooms where a high level of air cleaning is
requested, the cleaning intervention can be
made more often. It consists in the cleaning
of the coil, fan louvres, basin, ioniser (if pre-
sent), and all the parts in contact with the
treated air. Always check the filter condition,
cleaning it or, if necessary, replacing it.

Do not use jets or sprays of water during the
cleaning. Use the brush to remove any dust
deposits.
• Repairs and fine tuning: if you notice anoma-
lies.
• The fact that the blades of examinable
shrouds can be removed (operation done
only by adequately skilled technicians) en-
sures a thorough cleaning of the internal
components, which is particularly important
when installing the unit in crowded areas or
venues requiring high hygiene standards.
