Cleaning the Air Filter
The air filter is inserted in the holder (Figure 32, pos. 2) at the bottom side of the fan tray slot (Figure 32, pos. 6). The
soiling of the air filter (Figure 32, pos. 3) is caused by the pollution of the operating environment. A heavily soiled air
filter can cause excessive heating of the device. For this reason we recommend to clean the air filter as often as
necessary. The air filter can be changed during operation of the system.
