4.4.11.2 Modifying the Filter Load Index
The Filter Load Index menu allows the adjustment of the individual pollution
indices (large dust,chemical and fine dust) to reflect the actual pollution levels in
a particular environment more closely. This enables the Filter Life Monitor to
perform a more precise calculation of the remaining filter life.
1. Press the Menu key nine times to reach the Filter Load index menu.
2. Press and hold the Enter key until the cursor appears.
3. Press the key to modify the Large Dust index to reflect the large dust
pollution levels found in the environment where the system is used (for
guidance, see previous section).
4. Press the Enter key to save the Large Dust index setting.
5. Press the key to proceed to the Chemical index.
6. Press and hold the Enter key until the cursor appears.
7. Press the key to modify the Chemical index to reflect the chemical
pollution levels found in the environment where the system is used (for
guidance, see previous section).
8. Press the Enter key to save the Chemical index setting.
9. Press the key to preceed to the Fine Dust index.
10. Press and hold the Enter key until the cursor appears.
11. Press the key to modify the Fine Dust index to reflect the fine dust
pollution levels found in the environment where the system is used (for
guidance, see previous section).
12. Press the Enter key to save the Fine Dust index setting.

Limitations of Filter Load Indices
The concept of filter load indices allows for a more precise calculation of the remaining filter life than with regular
filter life counters.Yet, the determination of filter load indices underlies in its definition some natural limitations. For
this reason it may become necessary to change filters before the expiry of the indicated filter life, especially if there
is a noticeable decrease in filtration performance. In such a case, it may be necessary to adjust the appropriate filter
load settings to a higher value.
