The Refrigerant
WARNING
To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The used refrigerant is the fluoride R32, which is specially cleaned.
The refrigerant is flammable and inodorous. Furthermore, it can leads to explosion
under certain conditions. But the flammability of the refrigerant is very low. It can
be ignited only by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm
to the ozonosphere. The influence upon the greenhouse effect is also lower. R32
has got very good thermodynamic features which lead to a really high energy
efficiency. The units therefore need a less filling.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacture. Should repair be necessary, contact your
nea
rest authorized Service Centre. Any repairs carried out by unqualified
personnel may be dangerous. The appliance shall be stored in a room without
continuously
operating ignition sources. (for example: open flames, an operating
gas appliance
or an operating electric heater.) Do not pierce or burn.
Appliance shall be installed, operated and stored in a room with a floor area larger
than Xm .(Please refer to table "a" in section of " Safety Operation of Inflammable
Refrigerant" for Space X.)
Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s
instructions only. Be aware that refrigrants not contain odour. Read specialist’s
manual.

4.4. How to use the remote control to operate the unit
●SWITCHING THE UNIT ON AND OFF
Press the button to switch the unit on or off.
●SETTING THE OPERATING MODE
By pressing the Mode button several times it is possible to change the unit operating mode. The selected operating mode
symbol appears on the display.
→→ → →
: automatic mode
: cooling mode
: dehumidification mode
: fan only mode
: heating mode
When the automatic programme AUTO is selected, the unit may operate in COOLING or HEATING mode depending on the
temperature difference in place between the ambient temperature and the temperature selected on the remote control.
When the cooling mode is selected, the unit operates with a free temperature setting, lowering the ambient temperature.
When the dehumidification mode is selected, the unit operates with a free temperature setting, progressively lowering the
ambient temperature and humidity. When the dehumidification mode is in operation, the FAN button cannot be used. When
the heating mode is selected, the unit operates with a free temperature setting, raising the ambient temperature. When
the fan mode is selected, the unit operates without temperature settings, simply blowing air through the environment.
IMPORTANT!
♦The unit fan stops when the set temperature is reached and is then automatically reactivated at minimum
speed to prevent air stratification phenomena in the vicinity of the appliance.
♦When the COOLING, DEHUMIDIFICATION mode is selected, the fan may not start up straight away because the
ANTI-HEATING mode is present. When the HEATING mode is selected, the fan may not start up straight away
because the ANTI-COOLING mode is present.
●SETTING THE LOUVERS
In order to obtain optimal air distribution, adjust the motorised louvers, making sure that the air flow is not directly pointed at
anyone. For the motorised louvers, proceed as follows:

WARNING
It is necessary to stop the air conditioner and disconnect the power supply before
cleaning.
Cleaning the indoor unit and remote controller
CAUTIONS
●Use a dry cloth to wipe the indoor unit and remote controller.
●A cloth dampened with cold water may be used on the indoor unit if it is very dirty.
●The front panel of the indoor unit can be removed and cleaned with water. Then
wipe it with a dry cloth.
●Do not use a chemically treated cloth or duster to clean the unit.
●Do not use benzene, thinner, polishing powder, or similar solvents for cleaning.
These may cause the plastic surface to crack or deform.
Cleaning the air filter
A clogged air filter reduces the cooling efficiency of this unit. Please clean the filter
once every 2 weeks.
1. Lift the indoor unit panel up to an angle until it stops with a clicking sound.
2. Take hold of the handle of the air filter and lift it up slightly to take it out from the
filter holder, and then pull it downwards.
3. Remove the AIR FILTER from the indoor unit.
- Clean the AIR FILTER once two weeks.
- Clean the AIR FILTER with a vacuum cleaner or water, and then dry it up cool place.
4. Remove the healthy filter from its support frame as shown in the Figure on the left
(Not applicable to the units without electrostatic filter).
Do not touch this Electrostatic Filter within 10 minutes after opening the inlet grille; it
may cause an electric shock.
●Clean the electrostatic filter with mild detergent or water and dry in the sunlight for
two hours.
●Before re-install the Electrostatic Filter, check whether the corona line or support
frame is damaged or not.
5. Install the air freshening filter back into position.
6. Insert the upper portion of air filter back into the unit taking care that the left and
right edges line up correctly and place filter into position.
Maintenance
If you plan to idle the unit for a long time, perform the following:
(1) Operate the fan for about half a day to dry the inside of the unit.
(2) Stop the air conditioner and disconnect power. Remove the batteries from the
remote controller.
(3) The outdoor unit requires periodic maintenance and cleaning. Do not attempt to do
this yourself. Contact your dealer or servicer.
Checks before operation
 Check that the wiring is not broken off or disconnected.
 Check that the air filter is installed.
 Check if the air outlet or inlet is blocked after the air conditioner has not been used for a long time.
