BEFORE CALLING FOR SERVICE

The following conditions do not denote

equipment malfunctions.

Unit does not operate

• The unit will not operate if it is turned on im-

mediately after it is turned off. The unit will

not operate immediately after the mode is

changed. This is to protect the unit. Wait 3

minutes before operating the unit.

Unit does not send out warm air

• In heating operation, the indoor fan may not

start for 2 to 5 minutes after the unit is turned

on to prevent cold air from blowing out of the

unit.

• The unit is defrosting. Wait for 5 to 10 min-

utes.

Odors

•

Carpet and furniture odors that entered into the

unit may be sent out from the unit.

Cracking noise

• This sound is generated by the friction of the

unit expanding or connecting due to a tem-

perature change.

A low buzzing noise

• This is a sound of the unit generating Plasma-

cluster ions.

Swishing noise

• The soft, swishing noise is the sound of the

refrigerant flowing inside the unit.

Mist seen at indoor air outlet

• In cooling operation, this is caused by the dif-

ference between the room air temperature

and the air discharged.

Water vapour

• In heating operation, water vapour may flow

out of the outdoor unit during defrosting.

Odor emitted from the air outlet

• This is the smell of ozone generated from the

Plasmacluster Ion generator. The ozone con-

centration is very small, posing no adverse

effect on your health. The ozone discharged

into the air rapidly decomposes, and its den-

sity in the room will not increase.
