principle whereby the air, when it comes into
en
contact with a cold surface, wets it, releasing
it
humidity in the form of condensation drops.
The equipment is made up as follows (FIG. 2):
de
Air is extracted from the appliance: it passes
es
through the washable filter (1), the aluminium
coil (evaporator) (2), the hot exchanger (con-
fr
denser) (3), the fan (4) and finally the dehu-
midified air flows out and is recirculated into
nl
the room through the grille. The condensed
pt
water is collected in the tank (5). A micros-
witch stops the appliance when water in the
da
tank reaches a certain level. An electronic
fi
board (6) manages the correct operation of
the appliance.

►►3.1. REMOVAL OF THE PACKAG-
ING AND ASSEMBLY
bs
Remove the packaging taking care not to dam-
el
age the unit. Dispose of the packaging prod-
ucts (wood, plastic, cardboard), taking them to
zh
the specialised collection or recycling centres
(follow the local regulations in force).
CAUTION: Depending on the model, as-
semble the appliance, with any handles,
wheels and all relevant hardware (FIG. 3)
housed inside the packaging before commis-
sioning.
►►3.2. INSPECTION
All units are factory assembled and wired
(except for certain components). Upon re-
ceiving the unit, it must be immediately and
thoroughly inspected, checking that it has not
been damaged during transport or that no
parts are missing.
Before use, specifically check for any
dents on the external metal panels, including
those in the tank compartment. Also check
that the cable, plug and relevant insulation are
intact. Otherwise, it is FORBIDDEN to con-
nect and start the unit, which must be sent to
an authorised service centre.
►►3.3. OPERATING PRINCIPLES
CAUTION: To ensure correct operation
of the appliance, it is recommended to op-
erate the unit within the limits shown on
the technical data table.
►►3.4. POSITIONING
Set up the appliance to ensure an adequate
air flow.
CAUTION: Make sure that the appliance is
placed in such a way so as to prevent contact
with water.
►►3.5. SERVICE AREA
The hot air expelled by the fan must not be
obstructed. Avoid hot air recirculation between
suction and delivery to prevent compromising
the performance of the unit or even interrupt-
ing normal operation.
CAUTION: The equipment must not be
placed in cramped environments, which do
not allow adequate distribution of the air from
the air outlet grille into the room.
CAUTION: Do not place or hang objects
on the front panel, it may cause damage to
the unit.
