• When the air conditioner is used together with burners, thoroughly ven-

• Never place a burner at a place where it is exposed to the airflow from the
air conditioner.
Doing so can result in imperfect combustion of the burner.
• The microcomputer functions in the following cases:
• Air does not blow out when heating starts.
- To prevent any cool air from escaping, the indoor fan is gradually switched in
sequence from faint airflow/weak airflow/set airflow according to the tem-
perature rise of the blown out air. Wait a moment until the airflow comes out
naturally.
• The fan is not moving at the set speed.
- In some models, the system switches over to faint airflow when the tempera-
ture of the room reaches the set temperature. In other cases, it stops to
prevent any cool air from escaping during the defrosting operation.
• Air flows out even if operation is stopped.
- Approximately 1 minute after the stop of operation, the indoor fan sometimes
