|
|
|
||
|
|
|
||
This could affect your physical condition and cause health problems.
This may cause injury, as the internal fan rotates at high speed.
Failure to observe this may result in the batteries being swallowed or other accidents.
CAUTION
Only use approved fuses. |
Do not handle the switches with wet |
|
hands. |
|
Do not swing from the indoor unit.
Use of steel or copper wire instead of an approved fuse is strictly prohibited, as it may cause a breakdown or fire.
This may cause an electric shock.
If the indoor unit falls down, you may get injured.
Do not place a flammable insecticide or paint spray near the blower, nor spray it directly on the system.
This may result in a fire.
You should not expose any combustion appliance directly to the air stream of the air-conditioner.
The appliance may then work inadequately.
Do not wash the air-conditioner with water.
This could cause an electric shock.
The system should only be used for its original purpose and not for anything else like, for instance, preservation of food, plants or animals, precision devices or works of art.
Do not place anything containing water, like vases, on top of the unit.
Do not install the system where the airflow direction is aimed directly at plants or animals.
The system is only intended for use in ordinary domestic rooms. Any other use of the system may damage the quality of food, etc.
Water entering the unit could damage the insulation and therefore cause an electric shock.
This will damage their health.

Safety precautions
CAUTION
Do not sit on the outdoor unit nor put anything on it.
After a long period of use, check the unit's support structure from time to time.
Do not touch the aluminum fins on the air heat exchanger.
If the unit falls down or things drop off it, people could get hurt.
If you do not repair any damage right away, the unit may fall down and cause personal injury.
It may result in injury.
Do not place household electrical appliances or household items under neath the indoor or outdoor units.
Condensation falling from the unit may stain objects and cause accidents or electrical shock.

|
|
When you clean the system, stop the unit and turn off the power supply.
Do not place objects near the outdoor unit or allow leaves to gather around the unit.
Contact your dealer to clean inside the indoor unit, do not attempt to do by yourself.
Never open the panel while the internal fan is rotating.
If there are objects or leaves around the outdoor unit, small animals may enter unit and contact electrical parts and may cause a breakdown, smoke or fire.
The use of a non-approved detergent or improper washing method may damage the unit’s plastic components and cause leaks. Damage, smoke, or fire may also happen if the detergent comes in contact with electrical parts or the unit’s motor.
Stop the unit and turn off the power if you hear thunder or there is a danger of lightning.
It may damage the unit.
PRECAUTIONS FOR RELOCATION OR REPAIRS
DANGER
Do not perform any repairs or modifications by yourself. Consult the dealer if the unit requires repair.
Consult your dealer for repairs.
In case the air-conditioner is relocated elsewhere, contact your dealer or a professional fitter.
If you repair or modify the unit, it can cause water leaks, electric shocks or fire.
Wrong repairs could cause an electric shock, fire, etc.
Faulty installation may cause water leakage, electric shock, fire, etc.
If you notice anything abnormal (smell of burning, etc.), stop the system, turn off the power supply and consult your dealer.
Continued use of the system in abnormal circumstances may result in malfunctioning, electric shock, fire, etc.
If the air-conditioner fails to cool or warm the room, it may have a refrigerant leakage. Contact your dealer.
If refrigerant needs to be added, check with your dealer for proper instructions.
The refrigerant used in your air-conditioner is safe. However, if refrigerant unexpectedly leaks from the unit onto a fan heater, stove, hotplate or other heat source, harmful gases could be generated.

Page 7
NOTE
•Do not use old and new batteries together.
•Remove the batteries when the remote control is not used for a long period.
•The recommended effective period of a battery conforming to JIS or IEC should be 6 to 12 months with normal use. If used longer, or when an unspecified battery is used, liquid may leak from the battery, causing the remote control to malfunction.
•The recommendable effective period is printed on the battery. This may be shorter due to manufacturering time to the unit. However, the battery may still be in working order after expiry of its nominal life.
■When the display shows any abnormal condition, Press the ACL switch with the tip of a ballpoint pen.
Using the remote control holder
The remote control can be attached to a wall or pillar by using a remote control holder. Before installing the remote control, check that the air-conditioner receives the signals properly.
