Note:
For all other damage/defects, please contact Systemair. Defective safety-relevant fans (for Ex and smoke
extraction applications) must be replaced completely.
Maintenance
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:
• Fan unit in rare use (less than once a month)
• Fan used for emergency operation
• Durable ambient temperature > 40 ºC or < -10 ºC
