THE UNIT IS SEALED AND CONTAINS
FLUORINATED GREENHOUSE GASES
COVERED BY KYOTO PROTOCOL.
THE “GWP” IS LISTED IN THE “TECHNICAL
SPECIFICATIONS TABLE”.
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 tank or tray 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 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 the like) 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 which damages the
appliance and reduces its efficiency.
APPLIANCE DESCRIPTION
All portable 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). A microswitch
(6) stops the appliance when the water in the tank reaches a
set level. 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,
which lengthens 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;
when this light is on the appliance stops/does not work.
