EN HOW TO INSTALL BATTERIES
●Remove trhe lid in the rear part of the
remote control unit.
TEMPERATURE SENSOR SELECTOR
●Under normal conditions the room temperature is
detected and checked by the temperature sensor placed
in the remote controller (I FEEL icon displayed ).This
function is designed to provide a comfortable room
temperature by transmitting the temperature control
command from the location next to you. When using this
function, the remote, control should always be pointed
at the air conditioner, therefore it should be placed in
a position in which it is visible by the indoor unit (for
example, do not put it in a drawer).
●It is possible to disable the remote controller room sensor
by pressing and holding the FAN/I FEEL button. In
this case the I FEEL icon on the remote controller display
lights off and only the sensor placed in the air conditioner
becomes active.
USING THE REMOTE CONTROL UNIT
●Insert two AAA alkaline batteries of
1,5 V-DC making sure that point in
the direction marked in the battery
compartment.
●Set the clock (see procedure on page
6).
Remote controller is now ready for
operation.
●The batteries last average more than
six months, anyway it depends on how much you use
the remote control unit.
Remove the batteries if you do not use the remote
control unit for more than one month.
Replace the batteries when the battery symbol appears
on the remote control ( )
●The batteries of the remote control contain polluted
substances. Exhausted batteries must be disposed
according to the laws in force.
OPERATION WITH THE REMOTE CONTROL UNIT
When using the remote control unit, always point the unit
transmitter head directly at the air conditioner receiver.
The remote control unit transmits signals to the indoor
unit each time you press a key and at any temperature
change detected by the internal sensor. In case of
troubles (low batteries, remote control placed in
a position not visible by the indoor unit,...) room
temperature control is automatically switched to the
sensor of the indoor unit. In this case, the temperature
around the remote control unit may differ from the
temperature detected in the air conditioner position.
NOTE

FILTER CLEANING
Use a vacuum cleaner to remove light dust. If there is
sticky dust on the filter, wash the filter in lukewarm,
soapy water, rinse it in clean water, and dry it.
1. Grasp both ends of the front panel and pull it towards
you and up.
2. Push the filter up slightly, and then pull it down. Clean
the air filter.
AIR FILTER
The filter behind the front panel should be checked
and cleaned at least once every three months or more
frequently in case of excessive dust in the room.
Do not use fire or air dryer to dry the filter, to avoid
deformation or fire hazard.
HOW TO REPLACE THE FILTER
1. With the «FRONT» mark facing you, slide the filter up
into the unit and insert it in its place.
2. After installing the filter, close the front panel.
●Never use solvents, or harsh chemicals when cleaning
the indoor unit. Do not wipe the plastic casing using very
hot water.
●Some metal edges and the vanes are sharp and may
cause injury if handled improperly; be especially careful
when you clean these parts.
●The internal coil and other components of the outdoor
unit must be cleaned every year. Consult your dealer or
service centre.
CAUTION
CARE AND CLEANING
●Maintenance operations must be carried out by specially
trained personnel.
●For safety, be sure to turn the air conditioner off and also
to disconnect the power before cleaning.
●Do not pour water on the indoor unit to clean it. This will
damage the internal components and cause an electric
shock hazard.
WARNING
CASING AND GRILLE (INDOOR UNIT)
Clean the casing and grille of the indoor unit with a vacuum
cleaner brush, or wipe them with a clean, soft cloth.
If these parts are stained, use a clean cloth moistened with
