■ Title

-&nbsp;

&nbsp;The smell gets worse when it's not running under the cooling mode. It smells while the appliance is running in the fan mode.

■ Problem

- odor

■ Symptom

-&nbsp;

Mold/musty

smell

■ Possible Cause

-&nbsp;

The fan mode works in different mechanism compared to the cooling mode, which the users may perceive as more smelly.

■ Solution or Settings

▶&nbsp;

Cause of the odor

1)

&nbsp;

&nbsp;

During the cooling mode? (Outdoor unit

&nbsp;

in operation)

&nbsp;&nbsp;

&nbsp; : When cold air is supplied to the heat exchanger, it discharges cool air.

The odor particles are included within the moisture and the air&nbsp; inside the room.&nbsp; The low temperature of the discharged air slows down the spread of the odor particles

&nbsp;and many of the particles are discharged with the condensate water. For this reason the users cannot smell the odor.

2) During the fan mode

&nbsp;

? (Outdoor unit

&nbsp;

not in operation)

&nbsp;&nbsp;

: When the cold air is not discharged(during the fan mode) , the supply of cold air into the heat exchanger stopped&nbsp;

and the lukewarm fan wind is discharged.

&nbsp;&nbsp;

&nbsp;&nbsp;

&nbsp;During the fan mode, it does not form condensate and the condensate water on the heat exchanger is evaporated and discharged to the room again.

&nbsp;&nbsp;

&nbsp;&nbsp;

At this time, the odor particles are not discharged out of the product with condensate, but come out with the evaporated air. <p style="text-align: left; line-height: 100%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

The higher the temperature, the

faster

the speed that the odor spreads, that is, the spread of the odor particles speeds up. <p style="text-align: left; line-height: 100%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

Then the odor particles flow into the room within fan wind as the room temperature increases during the fan mode.<p style="text-align: left; line-height: 100%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

For this reason the users will perceive it as more smelly when its under the fan mode. <p style="text-align: left; line-height: 100%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

&nbsp;&nbsp;&nbsp; Remove the filter from the appliance

&nbsp;

and

prepare the citric acid water :

dilute commercially available citric acid&nbsp;

with water at a ratio of 1 (citric acid): 10 (water),&nbsp; <p style="margin: 0pt 0in; text-align: left; line-height: 100%; text-indent: 0in; font-family: Arial; font-size: 12pt; vertical-align: baseline; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

&nbsp;&nbsp;&nbsp;

After that, run the cooling mode with the desired temperature set to 18 ℃ for 20 to 30 minutes.

&nbsp;<p style="margin: 0pt 0in; text-align: left; line-height: 100%; text-indent: 0in; font-family: Arial; font-size: 12pt; vertical-align: baseline; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;"> <p style="margin: 0pt 0in; text-align: left; line-height: 100%; text-indent: 0in; font-family: Arial; font-size: 12pt; vertical-align: baseline; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

- Solution -

&nbsp;

1. Lower the desired temperature to run the cooling mode.

2.

Before turning

&nbsp;

off the air conditioner , use&nbsp; [fan mode] or [auto clean] to dry off the indoor heat exchanger for more than 10 minutes.

3.

Clean and replace the air filter and other functional filters on a regular basis according to the maintenance manual.

4.

If the product smells bad, turn off the appliance and remove the filter.

Prepare the citric acid water :

dilute commercially available citric acid with water at a ratio of

&nbsp;&nbsp;&nbsp; 1 (citric acid): 10 (water),&nbsp; and sprinkle this water sufficiently on the indoor heat exchanger.
