NOTE
The filter auto clean function takes around 10 minutes.
Execution of the cleaning function, always during the scheduled time slot of 0 to 3 hours, will start as soon as
possible considering the following conditions:
• during the first hour
the cleaning function will only be performed during thermostat OFF intervals or when the unit is not operating;
• during the second hour
same condition as during first hour or when cooling or heating demand is rather low;
• during the third hour
the unit forces execution of the cleaning function, even when the unit is operating. After completion of the
cleaning function, the unit will start normal operation again.
The unit will try to perform the cleaning function during the next scheduled time slot of 3 hours in case it was not
executed.
If the unit, in case of VRV, could not perform the cleaning function after elapse of 2 consecutive scheduled time
slots of 3 hours, error code AH09 displays on the remote controller (Refer to “NOTE” on page 16). The error
code remains displayed as long as the function is not completed, but the unit can operate normally at all times.
