1.2. During operation
Caution:
•Do not use any sharp object to push the buttons, as this may damage the remote controller.
•Do not twist or tug on the remote controller cord as this may damage the remote controller and cause malfunction.
•Never remove the upper case of the remote controller. It is dangerous to remove the upper case of the remote controller and touch the printed circuit boards inside. Doing so can result in fire and failure.
•Never wipe the remote controller with benzene, thinner, chemical rags, etc. Doing so can result in discoloration and failure. To remove heavy stains, soak a cloth in neutral detergent mixed with water, wring it out thoroughly, wipe the stains off, and wipe again with a dry cloth.
•Never block or cover the indoor or outdoor unit’s intakes or outlets. Tall items of furniture underneath the indoor unit, or bulky items such as large boxes placed close to the outdoor unit will reduce the unit’s efficiency.
Warning:
•Do not splash water over the unit and do not touch the unit with wet hands. An electric shock may result.
•Do not spray combustible gas close to the unit. Fire may result.
•Do not place a gas heater or any other open-flame appliance where it will be exposed to the air discharged from the unit. Incomplete combustion may result.
Warning:
•Do not remove the front panel or the fan guard from the outdoor unit when it is running.You could be injured if you touch rotating, hot or highvoltage parts.
•Never insert fingers, sticks etc. into the intakes or outlets, otherwise injury may result, since the fan inside the unit rotates at high speed. Exercise particular care when children are present.
•If you detect odd smells, stop using the unit, turn off the power switch and consult your dealer. Otherwise, a breakdown, electric shock or fire may result.
•When you notice exceptionally abnormal noise or vibration, stop operation, turn off the power switch, and contact your dealer.
•Do not over-cool. The most suitable inside temperature is one that is within 5 °C of the outside temperature.
•Do not leave handicapped people or infants sitting or standing in the path of the airflow from the air-conditioner.This could cause health problems.
Caution:
•Do not direct the airflow at plants or caged pets.
•Ventilate the room frequently. If the unit is operated continuously in a closed room for a long period of time, the air will become stale.
In case of failure
Warning:
•Never remodel the air conditioner. Consult your dealer for any repair service. Improper repair work can result in water leakage, electric shock, fire, etc.
•If the remote controller displays an error indication, the air conditioner does not run, or there is any abnormality, stop operation and contact your dealer. Leaving the unit as it is under such conditions can result in fire or failure.
•If the power breaker is frequently activated, get in touch with your dealer. Leaving it as it is can result in fire or failure.
•If the refrigeration gas blows out or leaks, stop the operation of the air conditioner, thoroughly ventilate the room, and contact your dealer. Leaving the unit as it is can result in accidents due to oxygen deficiency.
When the air conditioner is not to be used for a long time
•If the air conditioner is not to be used for a long time due to a seasonal change, etc., run it for 4 - 5 hours with the air blowing until the inside is completely dry. Failing to do so can result in the growth of unhygienic, unhealthy mold in scattered areas throughout the room.
•When it is not to be used for an extended time, keep the [power supply] turned OFF.
If the power supply is kept on, several watts or several tens of watts will be wasted. Also, the accumulation of dust, etc., can result in fire.
•Keep the power switched ON for more than 12 hours before starting operation. Do not turn the power supply OFF during seasons of heavy use. Doing so can result in failure.
1.3. Disposing of the unit
Warning:
When you need to dispose of the unit, consult your dealer. If pipes are removed incorrectly, refrigerant (fluorocarbon gas) may blow out and come into contact with your skin, causing injury. Releasing refrigerant into the atmosphere also damages the environment.

4. The smart way to use
Even minimal steps to care for your air conditioner can help make its use far more effective in terms of air-conditioning effect, electricity charges, etc.
Set the right room temperature
•In cooling operation, a temperature difference of about 5 °C between indoors and outdoors is optimum.
•If the room temperature is raised by 1 °C during air-cooling operation, about 10 % electric power can be saved.
•Excessive cooling is bad for health. It also results in the waste of electric power.
Clean the filter thoroughly
•Air filter is not provided within the unit, however filter (optional part) must be installed in the return air.
•If the screen of the air filter becomes clogged, the airflow and air-conditioning effect can be significantly reduced. Further, if the condition is left unattended, failure can result. It is particularly important to clean the filter at the beginning of the cooling and heating seasons. (When profuse dust and dirt have accumulated, clean the filter thoroughly.)
Prevent intrusion of heat during air-cooling
•To prevent the intrusion of heat during cooling operation, provide a curtain or a blind on the window to block out direct sunlight. Also, do not open the entrance or exit except in cases of dire necessity.
Carry out ventilation sometimes
•Since the air periodically gets dirty in a room that is kept closed for a long time, ventilation is sometimes necessary. When gas appliances are used together with the air conditioner, special precautions must be taken. If the “LOSSNAY” ventilation unit developed by our company is used, you can perform ventilation with less waste. For details on this unit, consult with your dealer.
5. Caring for the machine
Always have filter maintenance performed by a service person. Before care-taking, turn the power supply OFF.
Caution:
•Before you start cleaning, stop operation and turn OFF the power supply. Remember that the fan is rotating inside at high speed, posing a serious risk of injury.
•Indoor units are not equipped with filters. However, filter (optional part) must be installed in the return air to remove the dust of sucked-in air. (The standard filter should normally be cleaned once a week, and the long-life filter at the beginning of each season.)
How to clean
•Clear dust away lightly or clean it up with a vacuum cleaner. In the case of severe staining, wash the filter in lukewarm water mixed with dissolved neutral detergent or water, and then rinse off the detergent completely. After washing, dry it and fix it back into place.
Caution:
Never pour water or flammable sprays onto the air conditioner. Cleaning using these methods can result in the failure of the air conditioner, electric shock, or fire.
Replacement of filter

A |
Air outlet |
B |
Air inlet |
C |
Air filter (optional part) |
D |
Air filter handle |
(1)The air filter (optional part) should be located at the air inlet (rear side of the unit).
(2)Lift the air filter handles and pull the filter towards you.
(3)If you are going to use an air inlet conduit, remove the air filter. In this case, an air filter must be prepared locally and installed at the intake grille.
Caution:
•Do not dry the filter by exposing it to direct sunlight or warming it using fire, etc. Doing so can result in the deformation of the filter.
•Washing it in hot water (more than 50 degree C) can also result in deformation.

6. Troubleshooting
Before you call out a repair man, check the following table to see whether there is a simple solution to your problem.
●Unit does not cool very well.
•Clean the filter. (Dust and debris that collects in the filter will decrease airflow.)
•Check the temperature setting and adjust it if necessary.
•Increase the space surrounding the outdoor unit. Is the air intake or air outlet blocked?
•Is a window or door open?
●There is a “swishing” noise that occurs from the unit when water flows.
•This sound is made when refrigerant inside of the unit is flowing or refilling.
●A ticking noise is heard from inside of the unit.
•This sound is made when internal parts of the unit expand or contract when the temperature changes.
●An odor is detected in the room.
•This is caused when the unit expels odors that have been absorbed from the walls, carpets, furniture or clothing.
●A white mist is expelled from the indoor unit.
•This may occur just after the unit is turned on when a high level of humidity is present in the room.
●Water or moisture is expelled from the outdoor unit.
•This occurs to expel water or moisture that may have collected in the pipes or around piping fixtures.
•This occurs to dispel water from the heat exchanger.
●The indicators of the remote controller do not light up when operated.
•Turn on the power switch. “
” will be displayed.
●
indicator is displayed in the remote controller.
•The start and stop or operation mode or set temperature functions of the remote controller are not available when the 
indicator is lit.
●The start and stop functions are not available just after restarting the unit.
•Wait about three minutes (operation has stopped to prevent damage to the air conditioner).
●Unit does not start immediately.
•Wait until the unit restarts automatically. The compressor may hesitate resuming because a three-minute resume prevention circuit is incorporated in the outdoor unit for protection of the compressor.
●The unit started even though the start/stop button was not pushed.
•Is the timer on?
Press the start/stop button to stop the unit.
•Was a distant command sent from the remote controller? Find out if the remote controller was used.
•Is the 
indicator lit?
Find out if the remote controller was used.
•Is the automat (cooling/heating) mode selected? Press the start/stop button to stop the unit.
●The unit stopped even though the start/stop button was not pushed.
•Is the timer on?
Press the start/stop button to restart the unit.
•Was a distant command sent from the remote controller? Find out if the remote controller was used.
•Is the 
indicator lit?
Find out if the remote controller was used.
●“PLEASE WAIT” is displayed in the remote controller.
•An automatic startup test is being performed (will last for about two minutes).
●An error code is displayed in the remote controller.
•A self-diagnostic function is being performed to preserve the air conditioner. * Do not attempt to make repairs yourself. Turn the main switch off and contact the dealer from whom you bought the air conditioner. Provide him or her with the name of the unit and the information displayed in the re-
mote controller.
●The fan in the door unit does not operate.
•Check the over-current relay on the fan motor to determine whether it has been tripped.
If the over-current relay has been tripped, reset it after eliminating the cause of the problem (e.g. motor lock).
To reset the over-current relay, open the control box and press the green claw on bottom-right of the relay unit a click is heard. Release the claw and check that it returns to its original position.
Note that if it is pressed too hard it will not return to its original position.
If none of the above apply, turn the main switch off and contact the dealer from whom you bought the air-conditioner, telling him the model name and the nature of the problem. Do not try to fix the unit yourself.
In any of the following cases, turn off the main power switch and contact your local dealer for service:
•The operation lamp (on the main unit) flashes.
•The switches do not work properly.
•The circuit breaker trips frequently (or the fuse blows frequently).
•Water has accidentally been splashed into the unit.
•Water leaks from the unit.
•Something is accidentally dropped into the air-conditioner.
•An unusual noise is heard during operation.
The following do not indicate any malfunction:
Odours: smells such as tobacco or cosmetic odours may persist after they have been sucked into the unit.
Sound of liquid flowing inside indoor unit: this can occur during or after operation and is simply the sound of refrigerant being circulated inside the unit.
Ticking sound coming from indoor unit: this can occur when cooling has just begun or has just stopped. It is caused by the indoor unit shrinking or expanding slightly due to the change in temperature.
NOTE: The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors, and comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated.
Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.

7. Installation and transferring works, and checking
Regarding place for installation
Consult with your dealer for details on installation and transferring the installation.
Caution:
Never install the air conditioner where there is a risk of leakage of flammable gas.
If gas leaks and accumulates around the unit, fire can result.
Never install the air conditioner at the following place:
•where there is much machine oil
•near ocean and beach areas where there is much salt
•where humidity is high
•where there are hot springs nearby
•where there is much sulfureted gas
•where there is a high-frequency processing machinery (a high-frequency welder, etc.)
•where acid solution is frequently used
•where special sprays are frequently used
•Install the indoor unit horizontally. Otherwise, water leakage can result.
•Take sufficient measures against noise when installing the air conditioners at hospitals or communication-related businesses.
If the air conditioner is used in any of the above-mentioned environments, frequent operational failure can be expected. It is advisable to avoid these types of installation sites.
For further details, consult with your dealer.
Regarding electrical work
Caution:
•The electrical work must be undertaken by a person who is qualified as an electric engineer according to local regulations and the instruction given in the installation manual with the absolute use of exclusive circuits.The use of other products with the power source can result in burnout beakers and fuses.
•Never connect the grounding wire to a gas pipe, water pipe, arrester, or telephone grounding wire. For details, consult with your dealer.
•In some types of installation sites, the installation of an earth leakage breaker is mandatory. For details, consult with your dealer.
Regarding transfer of installation
•When removing and reinstalling the air conditioner when you enlarge your home, remodel, or move, consult with your dealer in advance to ascertain the cost of the professional engineering work required for transferring the installation.
Caution:
When moving or reinstalling the air conditioner, consult with your dealer. Defective installation can result in electric shock, fire, etc.
Regarding noise
•In installing work, choose a place that can fully bear the weight of the air conditioner, and where noise and vibration can be reduced.
•Choose a place where cool or warm air and noise from the outdoor air outlet of the air conditioner do not inconvenience the neighbors.
•If any alien object is placed near the outdoor air outlet of the air conditioner, decreased performance and increased noise can result. Avoid placing any obstacles adjacent to the air outlet.
•If the air conditioner produces any abnormal sound, consult with your dealer.
Maintenance and inspection
•If the air conditioner is used throughout several seasons, the insides can get dirty, reducing the performance.
Depending upon the conditions of usage, foul odors can be generated and drainage can deteriorate due to dust and dirt, etc.
