Mitsubishi Split-System Heat Pump SLZ-KF12NA

If two or more indoor units are connected, filter cleaning timing for each unit may be different, depending on the filter type.

The icon grid-like icon will appear when the filter on the main unit is due for cleaning.

When the filter sign is reset, the cumulative operation time of all units will be reset.

The grid-like icon is scheduled to appear after a certain duration of opera-tion, based on the premise that the indoor units are installed in a space with ordinary air quality. Depending on the air quality, the filter may require more frequent cleaning.

The cumulative time at which filter needs cleaning depends on the model.
