Air Purifying Filter catches pollen, dust, smoke of cigarettes, and unpleasant smell.

1. Hold the handle at the bottom center of the air filter, and pull it down.

2. Make sure that the net-side (black) of the filter is facing front (up) in fig. When setting the frame, the arrows marked on the claws should be pointing upward. Set 3 claws at the top of the frame first, and then set the rest of 2 claws at the bottom.
   Put a sticker of sample colors (of dirt) at the lower part of the filter frame.

3. Be sure to set air filters back in place. Look at page 23 for replacing air purifying filters.

< PROGRAM DRY Operation >

By the microcomputer function, the air conditioner takes away the moisture with a minimum temperature decrease.

• THREE-STEP Flow system
  1 Step… At the start of HEAT mode, the air blows out horizontally.
  2 Step …. When the air temperature has risen, the unit starts warming up the floor.
  3 Step …. When the flow and the walls are warmed up, the warm air starts blowing toward the area around people.

© Left/Right air flow direction adjustment
The vertical louvers may be adjusted as you please.
Note If adjustment is carried out during flap swing, the flap may strike your hand. Make adjustments once the swing has completely stopped appropriate position.

When the TIMER OFF is set;

1. The microcomputer controls the room temperature to ensure your comfortable sleep.
2. The airflow setting can be changed as you like.

**The temperature setting changes as shown below after TIMER OFF is

set.**
Operation by unit’s ON/OFF button

In case you can not operate the air conditioner immediately because of remote controller trouble or battery exhaustion, you can operate it with ON/OFF button.
Operating Condition
Use the system in the following temperature and humidity range for safe and effective operation. COOL Outdoor temperature: 19°C to 46°C PROGRAM DRY Indoor temperature: 18°C to 32°C Indoor humidity: 80% or below HEAT Outdoor temperature: —10°C to 21°C Indoor temperature: Under 28°C
Caution

1. If the temperature or humidity is beyond these conditions, safety devices may work and the conditioner may not operate
2. Long time operation in humidity over 80% may cause condensation on the unit and dripping

Replacing of Air Purifying Filter

Soiled Air Purifying Filter needs replacing. Air Purifying Filter should be replaced every three months on average, but if their color is similar to either of the sample colors, replace them promptly.

• How to replace Press the claws marked with an arrow, and remove the frame. Replace the filter inside, and set the frame back as they were. As for the order for Air Purifying Filter, please contact the shop you purchased this product.

• When you don’t need Air purifying filters, operate the unit without them.

Note

1. Air Purifying Filter can not be used more than once by washing.
2. Using Air Purifying Filters without replacing causes impairment of airflow and operating efficiency.

For Optimum Operation

The following are tips for saving energy consumption.

• Keep the room temperature at a comfortable level. Keeping it at a comfortable level helps save energy. Adjust the setting so as not to cool the room too much.
• Cover window with a blind or a curtain. Block the sunlight to save energy.
• Block air from outdoors. The energy for cooling will be wasted.
• Air conditioning the room evenly. Adjust the air direction appropriately.
• Use the TIMER effectively. Use it to operate the air conditioner only when necessary.
• Clean the air filters frequently. Clogged air filters cause inefficient operation or troubles. Clean them frequently.

To prevent drain leaks from the indoor unit, check the following. Check that the drain is discharged out of the drain hose outside while the air conditioner is in cooling operation (i.e. when cold air is flowing out of the indoor unit). (The discharge starts a little while after the start of the operation.) If there is no drain discharge, the drain hose is probably clogged by dust, trash, etc. and water may leak from the indoor unit.

Trouble Shooting

The following cases are not air conditioner troubles.

• A malfunction occurred during the operation. If the air conditioner has malfunctioned due to lightning or car wireless while operating, turn the safety breaker OFF. Then turn it ON after at least 3 minutes and press ON/OFF button on the remote controller again.
• Operation does not start soon after ON/ OFF button is pressed. In the following cases, the air conditioner waits on standby for 3 minutes before starting operation, for system protection. Just leave it as it is for a while.
• When turned on again immediately after turning off.
• When changing the operation mode.
• When power is restored after power failure.
• The outdoor fan rotates while the air conditioner is not in operation. In the following cases, the outdoor fan continues or starts rotating for system protection.
• For 30 seconds after the operation stopped.
• When the outdoor temperature is high.
• The unit gives out an odor. This happens when smells of the room, furniture, or cigarettes are absorbed into the unit and discharged with the airflow.
• Mists come out of the indoor unit. This happens when the air in the room is cooled into mist by the cold airflow during cooling operation.
• The operation stopped suddenly. The air conditioner may stop operating, on a sudden large voltage fluctuation, for system protection. It automatically resumes operation in about 3 minutes.

Check Before Calling a Repairperson
If the trouble remains even after checking the following points, do not attempt to repair the air conditioner by yourself but consult the electric appliance shop.

1. The air conditioner does not operate.
   • Hasn’t a breaker turned OFF or a fuse blown?
   • Isn’t it a power failure?
   • Are batteries set in the remote controller?

2. Does not sufficiently cool or heat.
   • Is the air filter clogged?
   • Is the room temperature set to the proper temperature?
   • Is the suction inlet or air discharge outlet of the indoor or outdoor unit blocked?
   • Are the windows or doors open?
   • Is the flap positioned properly?
   • Is the airflow rate set too weak?

3. The OPERATION lamp on the unit flashes on and off.
   • Aren’t the air inlets and the outlets of the indoor and the outdoor units all unblocked?

WARNING: CALL THE SHOP IMMEDIATELY.
If one of the following symptoms takes place, stop the operation immediately; then turn the breaker OFF and call the electric appliance shop.

1. An alien substance or water has been put in a remote controller or a unit by mistake.
2. The safety devices (fuses, the safety breaker, and the earth leakage breaker) cut off the operation frequently.
3. Switches and buttons often do not work properly.
