Sound

Cracking sound is heard.

• This sound is generated by the expansion/con-

traction of the front panel, etc. due to change in

temperature.

“Burbling” sound is heard.

• This sound is heard when the outside air is

absorbed from the drain hose by turning on the

range hood or the ventilation fan, making water

fl owing in the drain hose to spout out.

This sound is also heard when the outside air

blows into the drain hose in case the outside

wind is strong.
