ELETRICAL REQUIREMENTS
●
●
●
●
Before installation, check that the voltage of the electric supply in your home or office is the same as the voltage shown on the nameplate.
All wiring must conform to the local electrical codes. Consult your dealer or a qualified electrician for details.
Each unit must be properly grounded with a ground (or earth) wire or through the supply wiring.
Wiring must be done by a qualified electrician.
CAUTION
OPERATION lamp: This lamp lights up during operation.
It blinks once to announce that the remote control signal has been received and stored. It blinks continuously during the protection modes (defrosting, etc.).
STANDBY lamp: This lamp lights up when the air conditioner is connected to the power and ready to receive the remote control command.
TIMER lamp: This lamp lights up when the system is being controlled by the timer or sleep mode.
SAFETY INSTRUCTIONS
● Read this booklet carefully before using this air conditioner.
If you still have any difficulties or problems, consult your dealer for help.
● This air conditioner is designed to give you comfortable room conditions. Use this only for its intended purpose as described in this Instruction Manual.
INSTALLATION LOCATION
● We recommend this air conditioner to be installed properly by qualified installation technicians in accordance with the installation instructions provided with the unit.
WARNING
● Never use or store gasoline or other flammable vapor or liquid near the air conditioner. It is very dangerous.
● Never install electrical equipment, which is not protected with IPX1 protection (protection against vertical water drop), under the unit.
● The manufacturer assumes no responsabilities if the safety regulations or local codes are not observed.
WARNING
●
●
●
Do not install this air conditioner where there are fumes or flammable gases, or in an extremely humid space such as a green house.
Do not install the air conditioner where excessively high heat-generating objects are placed.
Do not install the air conditioner where the atmosphere is extremely damp or humid (e.g. greenhouse or laundry) it could be wetted by drops of water (i.e. in laundries).
CAUTION
● Never use the power main switch to start or stop the air conditioner: always use the ON/OFF button on the remote control unit or the selector switch on the unit.
● Do not stick anything into the air outlet of the air conditioner.
This is dangerous because the fan is rotating at high speed.
● Do not let children play with the air conditioner.
● Do not cool the room too much if babies or invalids are present.
Avoid
To protect the air conditioner from heavy corrosion, avoid installing the outdoor unit where salty sea water can splash directly onto it or in sulphurous air near a spa.

USING THE REMOTE CONTROL UNIT
HOW TO INSTALL BATTERIES
● Remove the lid in the rear part of the remote control unit.
● Insert two AAA alkaline batteries of 1,5 V-DC.
●
Make sure the batteries point in the direction marked in the battery compartment.
The batteries last about six months. Depending 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.
Press the +, -, SET and CLEAR buttons together after batteries replacement.
(This operation allows you to reset correctly all the programs.
The remote control unit is to be set up again).
Replace the batteries when the remote control unit lamp fails to light, or when the air conditioner does not receive the remote control unit signals.
The batteries of the remote control contain polluted substances exhausted batteries must be disposed according to the laws in force.
TEMPERATURE SENSOR SELECTOR
● Under normal conditions the room temperature is detected and checked by the temperature sensor placed in the air conditioner.
● Press the remote control I FEEL button to activate the temperature sensor placed in the remote control. This function is designed to provide a personalised environment by transmitting the temperature control command from the location next to you.
Therefore, in using this function, the remote control should always be aimed, without obstruction, at the air conditioner.
OPERATION WITH THE REMOTE CONTROL UNIT
CAUTION
Check that the circuit breaker on the power panel is turned ON and the the STANDBY lamp is light up.
When using the remote control unit, always point the unit transmitter head directly at the air conditioner receiver.
HOW TO TURN ON THE AIR CONDITIONER
Press the ON/OFF button to turn the air conditioner on. The indicator OPERATION will light up, indicating the unit is in operation.

CARE AND CLEANING
NOTES
• The flap automatically closes when the unit is off.
• During the heating operation, the fan speed will be very low and the flap will be in the horizontal position (position 6 ) until the air being blown out of the unit begins to warm.
Once the air warms up, the flap position and fan speed change to the settings specified with the remote control.
WARNING
● 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.
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 a mild liquid detergent.
When cleaning the grille, be careful not to force the vanes out of place.
The air intake grille can be removed in order to wash it with water.
CAUTION
• Use the FLAP button on the remote control to adjust the position of the flap. If you move the flap by hand, the factual flap position and the flap position on the remote control may no longer match. If this should happen, shut off the unit, wait for the flap to close, and then turn on the unit again; the flap position will now be normal again.
• Do not have the flap pointed down during cooling operation. Condensation may begin to form around the air vent and drip down.
CAUTION
● 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.

AIR FILTER
The filter behind the air intake grille should be checked and cleaned when the filter lamp lights up (see page 3).
HOW TO REMOVE THE FILTER
Air intake grille
Air filter
1.
Grasp both ends of the air intake grille and pull it towards you and up.
2.
Push the filter up slightly, and then pull it down.
FILTER CLEANING
Use a vacuum cleaner to remove light dust. If there is sticky dust on the filter, wash the filter in lukewarm, soap water, rinse it in clean water, and dry it.
HOW TO REPLACE THE FILTER
Insert into the groove on the unit
1.
With the «FRONT» mark facing you, slide the filter up into the unit and then lower the handler into the groove on the unit.
2.
After installing the filter, press the locations marked by the arrows ( ) and close the air intake grille.
3.
Press the RESET button to turn off the filter lamp (see page 3).
TIPS FOR ENERGY SAVING
Air intake grille
Air filter
DO NOT:
● Block the air intake and outlet of the unit.
If they are obstructed, the unit will not work well, and may be damaged.
● Let direct sunlight into the room. Use sunshades, blind or curtain.
DO:
● Always try to keep the anti-mold filter clean. A clogged filter will impair the performance of the unit.
● To prevent conditioned air from escaping, keep windows, doors and any other openings closed.
TROUBLESHOOTING
WARNING
The use of portable telephones near the air-conditioner may cause disturbance to its normal operation and must be avoided.
