The cooling fan dissipates the heat generated inside the unit so that the unit can be operated
normally. The cooling fan is activated automatically to supply cool air to the unit.
Please observe the following cautions for your safety.
• Make sure the unit is well-ventilated. If the unit has poor ventilation, the temperature inside the unit could rise
and may damage it.
• Do not obstruct the cooling fan or ventilation holes. (If the cooling fan or ventilation holes are covered with a
newspaper or cloth, heat may build up inside the unit and fire may result.)
