2-1. Cleaning the Air Filter
There are filters at three locations in the unit; one at the
back of the meter panel, one at the back of the front panel
and the third at the back of the blank panel.
If dirt accumulates on the filters, ventilation will be
blocked and heat will build up inside the unit, which may
cause the unit to fail.
Therefore, the filters should be cleaned periodically.

For details of filter replacement, refer to the MAV-555
