Safety Precautions

I Read the following warnings and cautions carefully before operating the system and use it correctly. I This manual classifies the precautions to the user into two categories on the right. Be sure to follow all as they are all important to ensure safety. I After reading this manual, keep it in a place easily accessible to the user for future reference.

WARNING

Failure to follow a warning is very likely to result in such grave consequences as death or serious injury.

CAUTION

Failure to follow a caution may result in serious injury or property damage, and in certain conditions, may result in a grave consequence.
G Do not expose your body to the cool air for a long time, do not cool the room too much. It will affect your physical conditions and cause health problems. G Do not put a finger, a rod or other objects into the air outlet or inlet. As the fan is rotating at a high speed, it will cause injury. G Do not attempt to repair, relocate, modify or reinstall the air conditioner by yourself. Incorrect work will cause electric shocks, fire etc. For repairs and reinstallation, consult the shop where you bought the air conditioner. G If anything abnormal such as a burning smell occurs, stop the operation immediately and turn the breaker OFF. Continued abnormal operation will cause troubles, electric shocks, fire etc. If anything is abnormal, consult the shop where you bought the air conditioner. G If the air conditioner is not cooling properly, the refrigerant may be leaking, so see the dealer where the unit was purchased. Check with a qualified repairman before attempting any repairs, which might accompany addition of refrigerant. The refrigerant used in the air conditioner is safe. Although leaks should not occur, if for some reason any refrigerant happens to leak into the room, make sure it does not come in contact with any flame, such as fan heaters, kerosene heaters, or gas ranges, as this may result noxious substances being generated.
G Do not use the air conditioner for preservation purposes. Do not use it for preserving precision instruments, foods, plants, animals, works of fine arts etc. Performance or quality may deteriorate and animal or plant life may be shorter. G Do not operate the air conditioner with a wet hand. It may cause an electric shock. G Ventilate the room from time to time. Be careful especially when using a burning appliance in the same room. Insufficient ventilation may cause shortage of oxygen. G Before cleaning, be sure to stop the operation and turn the breaker OFF. As a fan is rotating at a high speed, cleaning during operation may cause injury. G After a long use, check the unit stand and fittings for damage. The unit may drop and cause injury if damage is left unrepaired.
G Do not stand or sit on the outdoor unit. Do not place any object on the unit. The object or the person may fall down or drop, causing injury. G Do not place under the indoor or outdoor unit anything which must be kept away from moisture. Indoor unit : moisture in the air may condense and drip in certain conditions. outdoor unit : during cooling operation, condensation may drip from the piping connections. G Do not wash the unit with water. It may cause an electric shock. G Do not place a burning appliance in places exposed to the air flow from the unit or under the indoor unit. It may cause incomplete combustion or deformation of the unit from heat. G Do not place a vessel containing water on the unit. Water may penetrate into the unit and degrade electrical insulations, resulting in an electric shock. G Do not expose plants or animals directly to the air flow. It may cause adverse effects on the plant or the animal. G Do not block air inlets nor outlets. Impaired air flow may result in insufficient performance or troubles. G Do not allow children to mount on the outdoor unit or avoid placing any object on it. Falling or tumbling may result in injury.

Installation

G Do not attempt to install the air conditioner by yourself. Consult the service shop or a qualified technician. Incorrect work will result in water leakage, electric shocks or fire. For installation, consult the service shop where you bought the unit or a qualified technician. G The air conditioner must be earthed. Incomplete earthing may result in electric shocks. Do not connect the earth line to a gas pipe, water pipe, lightening rod, or a telephone earth line.
G Depending on the environment, an earth leakage breaker must be installed. Lack of an earth leakage breaker may result in electric shocks. G Do not install the air conditioner in places where flammable gas may leak. If leaked gas should accumulate near the unit, fire may occur. G Arrange the drain hose to ensure smooth drainage. Incomplete drainage may cause wetting of the building, furniture etc. G Do not connect the air conditioner to a power supply different from the specification. It may cause trouble or fire.
Installation site I To install the air conditioner in the following types of environments, consult the shop. G Places with an oily ambient or where steam or soot occurs. G Salty environment such as coastal areas. G Places where sulfide gas occurs such as hot springs. G Places where snow may block the outdoor unit. The drain from the outdoor unit must be discharged to a place of good drainage. Consider nuisance to your neighbours from noises I For installation, choose a place as described below. G A place solid enough to bear the weight of the unit which does not amplify the operation noise or vibration. G A place from where the air discharged from the outdoor unit or the operation noise will not annoy your neighbours. Electrical work G For power supply, be sure to use a separate power circuit dedicated to the air conditioner. System relocation G Relocating the air conditioner requires specialized knowledge and skills. Please consult the shop where you bought the air conditioner if relocation is necessary for moving or remodeling.

Note for Multi System

G Priority-room setting
When setting the priority-room during installation, the indoor units operation mode always takes priority. When the priority-setting room unit is operated in POWERFUL mode, there are times that air conditioners in other rooms will temporarily stop in order to centralize power to the unit in the room. Please adjust the priority-room setting to match your life style. Moreover, for priority-room settings, please consult the service shop where you bought the unit. Priority-room setting is applied to only, 4MK90.

Trouble Shooting

G These cases are not troubles. The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Operation does not start soon. G When ON/OFF button was pressed soon after operation was stopped. G When the mode was reselected. The outdoor unit emits water or steam. Mists come out of the indoor unit.

Explanation

G This is to protect the air conditioner. You should wait for about 3 minutes.

G Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips. I This happens when the air in the room is cooled into mist by the cold air flow during cooling operation.
The indoor unit gives out odour.
I This happens when smells of the room, furniture, or cigarettes are absorbed into the unit and discharged with the air flow. (If this happens, we recommend you to have the indoor unit washed by a technician. Consult the service shop where you bought the air conditioner.)
The outdoor fan rotates while the air conditioner is not in operation.
I After operation is stopped: The outdoor fan continues rotating for another 60 seconds for system protection. I While the air conditioner is not in operation: When the outdoor temperature is very high, the out door fan starts rotating for system protection.
The operation stopped suddenly. (OPERATION lamp is on)
I For system protection, the air conditioner may stop operating on a sudden large voltage fluctuation. It automatically resumes operation in about 3 minutes.
G Check again Please check again before calling a repair person.
The air conditioner does not operate. (OPERATION lamp is off) G Isnt it a power failure?
G Hasnt a breaker turned OFF or a fuse blown? G Are batteries set in the remote controller? G Is the timer setting correct?

Cooling effect is poor.

G Are the air filters clean? G Is there anything to block the air inlet or the outlet of the indoor and the outdoor units? G Is the temperature setting appropriate? G Are the windows and doors closed? G Are the air flow rate and the air direction set appropriately?
Operation stops suddenly. (OPERATION lamp blinks.)
G Are the air filters clean? G Is there anything to block the air inlet or the outlet of the indoor and the outdoor units? Clean the air filters or take all obstacles away and turn the breaker OFF. Then turn it ON again and try operating the air conditioner with the remote controller. If the lamp still blinks, call the service shop where you bought the air conditioner. G Are operation modes all the same for indoor units connected to outdoor units in the multi system? If not, set all indoor units to the same operation mode and confirm that the lamps blink. If the lamps stop blinking after the above steps, there is no malfunction. G The air conditioner may malfunction with lightening or radio waves. Turn the breaker OFF, turn it ON again and try operating the air conditioner with the remote controller.
An abnormal functioning happens during operation.
G Call the service shop immediately. WARNING I When an abnormality (such as a burning smell) occurs, stop operation and turn the breaker OFF.
Continued operation in an abnormal condition may result in troubles, electric shocks or fire. Consult the service shop where you bought the air conditioner.
I Do not attempt to repair or modify the air conditioner by yourself.
