While working in high places, slipping or falling may result in serious injury.
• 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.

If it is stained, use a clean cloth moistened with a mild liquid detergent. When cleaning it, be careful not to force the flaps out of place.
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 fins 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 center.
Cleaning the flaps
• The air outlet flap can be removed and washed with water.
• Be sure to always stop operation before removing the flap.
• After washing with water, allow it to dry, and then remount it.
CAUTION
• Do not move the flap with your hands.
• When using a footstool or the like, be careful not to let it tip over.
Cleaning the main unit and remote control unit
• Wipe clean using a soft, dry cloth.
• To remove stubborn dirt, moisten a cloth in warm water no hotter than 104 °F, wring thoroughly, and then wipe.

Air filter
The air filter collects dust and other particles from the air and should be cleaned once every 6 months.
If the filter gets blocked, the efficiency of the air conditioner drops greatly.
NOTE
The frequency with which the filter should be cleaned depends on the environment in which the unit is used.
How to remove the filter
1.
Slide the two latches of the air intake grille with your thumbs in the direction of the arrow to open the grille.

• When the air intake grille has been opened, rotating parts (such as the fan), electrically charged areas, etc. will be exposed in the unit’s opening. Bear in mind the dangers that these parts and areas pose, and proceed with the work carefully.
• Periodically check the outdoor unit to see if the air outlet or air intake is clogged with dirt or soot.
Care: After a prolonged idle period
Check the indoor and outdoor unit air intakes and outlets for blockage; if there is a blockage, remove it.
Care: Before a prolonged idle period
• Operate the fan for half a day to dry out the inside.
• Disconnect the power supply and also turn off the circuit breaker.
• Clean the air filter and replace it in its original position.
• Outdoor unit internal components must be checked and cleaned periodically.
