11.3 Maintenance
To ensure a reliable operation of the fan, we recommend periodic maintenance intervals. These maintenance intervals must be speci-
fied by the operator. The frequency of maintenance activities or additional activities must be decided ac cording to the use of the fans. It
is important for traceability to create a maintenance plan, in which the work performed is written down.
The maintenance intervals should be shorter if the following conditions (among others) apply:
· Fan used as kitchen exhaust application
· Ambient temperature > 104°F or < 14°F
The following check list provides points of reference for the tasks to be carried out.
