3 4

Set to prohibit the filter cleaning operation.

Return to the filter cleaning operation setting.

Operate the manual filter cleaning operation. (Page 34)

Set to prohibit the filter cleaning operation again.

(Method of setting 1, 2, 4, page 34)

• If the filter cleaning is performed after a long interval, dust on the micro mesh stainless filter may not be completely cleaned just by one cycle of filter cleaning. To avoid this, frequent filter cleaning is recommended. (Standard cleaning frequency is once every 2~3 days.)

• If the filter is not cleaned evenly at the time the filter cleaning has been completed, perform the manual filter cleaning operation one more time after an interval of at least 5 minutes. (To protect the appliance, the filter cleaning cannot be performed again within 5 minutes after the previous filter cleaning is completed.)

• Filter may not be cleaned evenly due to long interval of filter cleaning or due to the environment in which the air conditioner is used. To solve this problem, clean the micro mesh stainless filter. (Page 37)

•

If the (MANUAL CLEAN) button is pressed while the filter cleaning operation is

prohibited, a long beep

sounds and the (CLEAN) indicator blinks. (Lit for 1 second/off for 1 second, for 10 seconds)

• To protect the appliance, the filter cleaning operation is not performed even if the (MANUAL CLEAN) button on the remote controller is pressed during approximately 5 minutes after filter cleaning operation (i.e., filter cleaning operation which is performed after the air conditioner power is turned on; automatic filter cleaning operation; and manual filter cleaning operation which is performed using the remote controller). A long beep sounds and

(CLEAN) indicator blinks. (Lit for

1 second/off for 1 second, for 10 seconds)

• If the front panel is opened at the start of or during filter cleaning operation, the cleaning unit stops for safety reason and the (CLEAN) indicator repeats lighting/ dimming. (Lit for 1 second/dim for 1 second)

IN THE FOLLOWING CASES, THE (CLEAN) INDICATOR REPEATEDLY BLINKS, LIGHT UP OR DIM. (IT IS NOT A MALFUNCTION)

n The filter cleaning unit is out of order if the (CLEAN) indicator on the indoor unit still repeatedly on for 4 seconds/off for 1 second. In this case, filter cleaning operation is unavailable, however other functions of the air conditioner are available without being affected.

• Contact your sales agent if the filter cleaning unit malfunction.

UNDERSTANDING THE OPERATING MECHANISM

NAMES AND FUNCTIONS OF EACH PART (Page 4)

CAUTION

Do not use a stove or any other high temperature devices in proximity to the indoor unit.

PROHIBITION

Movable panel

• Movable panel opens automatically when the air conditioner

starts operation for efficient heat exchange of the air. It will close automatically once the air-conditioner stops. Attempt to move the panel manually could result in failure of the unit. Do not use excessive force to open/close the movable panel.

• Do not touch the movable panel while it is moving to avoid the

risk of finger entrapment.

Heating capability

• This room air conditioner utilizes a heat pump system that absorbs exterior heat and brings it into a room to

be heated. As the ambient temperature gets lower, heating capability will also lower. In such a situation, the PAM and inverter work to increase compressor rpm to keep the unit’s heating capability from decreasing. If the unit’s heating performance is still unsatisfactory, other heating appliances should be used to augment this unit’s performance.

• The air conditioner is designed to heat an entire room so that it may take some time before you feel warm.

Timer operation is recommended for effective preheating ahead of the desired time. (Page 28)

• When outside temperature becomes lower while humidity remains high, condensation forms on the heat

exchanger of the outdoor unit and the heating efficiency may be affected if condensation is not removed. To prevent this problem, the air conditioner performs condensation-removing operation automatically. At this time, the heating operation is suspended and it usually takes approximately 5~10 minutes (maximum of 20 minutes) to resume the heating operation.

Cooling, dehumidifying and dry cool capabilities

• If the heat present in a room exceeds the unit’s cooling capacity (for example, if there are many people in

the room or other heating appliances are used), the preset room temperature may not be reached.

• The preset temperature may not be reached if a heat source or humidity which exceeds the air conditioner’s

dehumidifying ability is present in the room.

Piping which is too long could lower the heating/cooling performance.

Page 44

– 44 –

THE IDEAL WAYS OF OPERATION

1. An average room temperature setting is probably the best for you as well as being economical.

• Excessive cooling or heating is not recommended for health reasons. High

electricity bills may also result.

• Close the curtains or blinds to prevent heat from flowing into or escaping the

room as well as to make more effective use of electricity.

2. At intervals, the doors and windows should be opened to let fresh air in.

Make sure the room is ventilated when operating the air conditioner at the same time as other heating appliances.

3. Make efficient use of air quality monitor and mold monitor when going out.

(Refer to page 21~22 on air quality monitor and mold monitor)

4. Make efficient use of the timer before going to sleep.

(Refer to page 28~31 on using the timer)

5. The following must never be used for cleaning the indoor and outdoor units:

• Benzine, thinner and scrub can damage plastic surfaces or coating.

• Hot water above 40°C can shrink the filter and deform plastic parts.

6. Do not block the air intake and air outlet.

• Do not block the air outlets and intakes of the indoor and outdoor units with

curtains or other obstacles which could degrade air conditioner performance and cause unit failure.

ANTI-MOLD WASABI CASSETTE

• Anti-mold elements with wasabi aroma prevents mold growth inside the dust box in which the dust collected

by filter cleaning operation is kept. Although only a trace amount of anti-mold elements is released, there may be wasabi smell in the room depending on the environment in which the air conditioner is used. If you feel this smell is unpleasant, block one of the anti-mold element outlets with a commercially available adhesive tape. If this measure is taken, the amount of anti-mold element to be released will be reduced and the anti-mold effect will also be less accordingly. To prevent mold growth, frequent cleaning of the dust box is recommended.
