10.3.1. Counter cross-flow heat exchanger
10.3. Maintenance
Counter cross-flow heat exchangers generally require no maintenance. For hygienic reasons, clea -
ning of the exchanger is occasionally recommended. Damage to the blades should always be avo -
ided. Use warm, flowing water for cleaning.

10.3.2. Air filters
The differential pressure increases as one of the air filters becomes more clogged. When the pres -
sure reaches the value set on the corresponding pressure sensor, this can be seen on the status dis -
play. The filter must be changed when the level of clogging reaches 100%. To reset the filter display
after changing the filter, press buttons A (▲ and ▼) at the same time until the clogging level display
shows 0% again. The filter change counter will then increase by one.
To ensure that the air filter is changed correctly, proceed as follows:
•
The air filter can be removed without the use of tools.
•
The air filter should be replaced if severely clogged.
•
When changing the filter, make sure that the filter frame is sitting correctly on the guide rail in the
device.
•
Finally, the filter display should be reset and the new air filter calibrated (see Section 9.4. „Cali -
brate filter“)
Find filters positions in the device description or safety instructions.
