Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is

provided.

We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are

specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning,

replacing defective components or other corrective measures. For traceability reasons, a maintenance plan must be

created which documents the work carried out. This must be created by the operator. If the operating conditions are

"extreme", the maintenance intervals must be reduced so that maintenance is carried out more frequently. Examples

of extreme operating conditions:

• Ambient temperature > 40 ºC or < 0 ºC, or temperature fluctuations > 20 K
