the power main switch is set to on. Reset the circuit breaker to ON.

• Frost sometimes forms on the outdoor unit during heating operation. In that case, the unit
automatically performs defrosting (for 2 to 10 minutes) for improving the heating efficiency.
• In the defrosting operation, the airflow from both the indoor and outdoor units stops.
• A hiss sound is heard when the flow of the refrigerant is changed for defrosting.
• The water resulting from automatic defrosting during the heating operation is drained from
the outdoor unit.
The air flow changes even though the FAN button is not set to the AUTO mode.
• When the temperature of the blown air goes down during heating operation, the air
conditioner automatically changes or stops the air flow from the indoor unit so that the
people in the room do not feel chilly.
A white mist of chilled air or water is generated from the outdoor unit.
• Steam is sometimes generated from the indoor unit during cooling operation or the
outdoor unit during defrosting operation.
Automatic operation of vertical air flow louvers
• When the room temperature or outdoor temperature is high during the heating operation,
the vertical air flow louvers close once and then set themselves automatically to the
original position setting again.
The FILTER indicator turns on.
• This indicator turns on after PURE operation has been performed for approximately 1000
hours.
• The indicator may turn on if the front panel is not firmly closed.
• The indicator may turn on if the plasma pure filter is not securely attached.
Sounds made from the indoor unit
• The plasma pure filter may make a humming, clicking, or buzzing sound when it is dirty.
• When the power is turned on or the air conditioner is stopped, the vertical air louvers may
make a rattling sound or shuttling sound.
• Some parts may expand or shrink due to temperature fluctuations, and this can result in a
slapping sound.
• When the refrigerant is flowing, a hissing sound or gurgling sound can result.
• A hissing sound can be made when the air conditioner is switched to defrosting operation
during heating operation.
