SAFETY WARNINGS

The dehumidifier must always be connected to an
efficiently grounded socket. As with all electrical
appliances, failure to observe this safety measure
is a potential source of danger that the constructor
does not respond for in any way.
The appliance must only be dismantled by a
qualified technician using the appropriate tools.
The appliance must always be in an upright position
when it is plugged into an electric socket and must
not be handled with sharp movements. Any water
leaking from the dehumidifier could wet the electric
parts with the obvious risk of danger, therefore the
dehumidifier must always be unplugged before it is
moved and the tank emptied [if present] before it is
lifted.
Should any water be spilt due to sharp movements,
the dehumidifier must remain turned off and
unplugged in an upright position for at least eight
hours before it can be turned on again.
This dehumidifier takes the air in from the rear and
expels it through the front grid, and therefore the
rear panel which holds the air filter must be at a
distance of at least 15 centimetres from the wall.
The appliance must not be turned on in confined
spaces where the expelled air from the front grid is
unable to circulate freely, however the side panels
can be placed next to a wall without affecting the
appliance efficiency.
This dehumidifier has been constructed to the
strictest safety standards. No sharp items (such as
screwdrivers, knitting needles or similar objects)
must be introduced into the front grid or the opening
in the rear panel when the filter is removed as that
is extremely dangerous for human safety and can
damage the appliance.
Do not wash the appliance with water; just use a
damp cloth after unplugging it from the socket.
Do not cover the front grid with clothes or other
items as this could damage the appliance and be a
source of danger.
Clean the filter periodically; on average once a
month but if the dehumidifier is used in very dusty
surroundings the filter should be cleaned more
frequently. Refer to the specific filter cleaning
chapter. When the filter is dirty the expelled air is
hotter than normal and can damage the appliance
and reduce its efficiency.

DEHUMIDIFIERS
DESCRIPTION
All dehumidifiers use cooling cycles with compressor. The
appliances are described below.
FUNCTIONS
This dehumidifier is an appliance working with a cooling
cycle based on the physical principle whereby the air is
exposed to a cold surface and wets it, giving off humidity
as drops of condensation, or ice if the room temperature
is very low.
In practice, a cooling machine keeps a coil cold that the
air is passed through and therefore the air cools down and
has the humidity removed. The air then passes through a
hot heat exchanger and is heated up to return to the room
dehumidified and slightly warmer than at the beginning.
Refer to the diagram (Fig. 1-2):
The air is taken in from the rear of the appliance and
passes through the filter (1), the cold aluminium coil
(evaporator) (2), the hot exchanger (condenser) (3), the
fan (4) and finally the dehumidified air is expelled into
the room through the front grid. The condensed water is
collected in the tank (5) [if present] or discharged by the
specific pipe. A micro-switch (6) stops the appliance when
the water in the tank reaches a set level [if present]. The
moisture gauge (7) enables the dehumidifier to work when
the room humidity is higher than the required level. An
electronic board (8) controls the defrosting and prevents
any dangerous starting of the compressor (9) too soon
and delays its ignition.
These appliances have hot gas defrosting devices
installed, with a solenoid valve for the hot gas bypass,
a special electronic board (with double relay) and a
defrosting thermostat.
This defrosting system is exclusive to our appliances:
in practice, a system with a thermostat and electronic
control that uses the hot gas bypass only for the time
that is strictly needed. This allow to extend the life of the
appliance and reduces the time of the hot gas phase.

CONTROL PANEL

The control panel is in the front of the appliance and
contains four lighted signals (Fig. 3):
•DEFROST (red led): Comes on when the compressor
is on pause or the first ignition is delayed or during the
defrosting phase.
•WORKING (red led): Comes on when the humidity gauge
requests the appliance functions.
•POWER (red led): Comes on when the appliance is
powered.
•FULL (green led): Comes when the condenser tank is
full [if present]; when this light is on the appliance stops/
does not work.
