CARE AND CLEANING

WARNING

1.For safety, be sure to turn the air conditioner off and also to disconnect the power before cleaning.

2.Do not pour water on the indoor unit to clean it. This will damage the internal compo- nents and cause an electric shock hazard.

Air intake and outlet side Clean the air intake and outlet side of the indoor unit with a vacuum cleaner brush, or wipe them (Indoor unit) with a clean, soft cloth.

If these parts are stained, use a clean cloth moistened with a mild liquid detergent. When clean- ing the air outlet side, be careful not to force the vanes out of place.

CAUTION

1.Never use solvents or harsh chemicals when cleaning the indoor unit. Do not wipe plastic parts using very hot water.

2.Some metal edges and the fins are sharp and may cause injury if handled improperly; be especially careful when you clean these parts.

3.The internal coil and other components of the outdoor unit must be cleaned every year. Consult your dealer or service center.

Air filter The air filter collects dust and other particles from the air and should be cleaned at regular intervals as indicated in the table below or when the filter indication ( ) on the display of the remote control unit (wired type) shows that the filter needs cleaning. 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 clean the filter>

1.Remove the air filter from the air intake grille.

2.Use a vacuum cleaner to remove light dust. If there is sticky dust on the filter, wash the fil- ter in lukewarm, soapy water, rinse it in clean water, and dry it.

<How to remove the filter>

1.Use a screwdriver to remove the bolt screw on each side for the two latches. (Be sure to reattach the two bolt screws after cleaning.)

2.Press on the two latches of the air intake grille with your thumbs in the direction of the arrow to open the grille.

3.Open the air intake grille downward.

CAUTION

When cleaning the air filter, never remove the safety chain. If it is necessary to remove it for servicing and maintenance inside, be sure to reinstall the safety chain securely (hook on the grille side) after the work.

When the filter has been removed, 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.
