Operating instructions
To operate the fan, we recommend the production of process instructions. These documents are intended to
simplify repetitive workflows, reduce the risk of incorrect operation and are a valuable aid for training and
when personnel changes occur.
If the fan must be qualified, process instructions are an absolute prerequisite.
You will find important instructions on how to produce process instructions in various chapters of this
operating manual.
To help ensure the safe operation of the fan, COLASIT offers the service of
reviewing process instructions prepared by the operator

Logbook
For your own safety and as an aid to personal responsibility, we recommend the keeping of a logbook for the
entire period during which the fan is in service.
All events should be recorded in the logbook.
In case of damage and also in case of an accident, this document is the first source of information.
For example, enter the date and your signature:
-
Start and end of a work cycle

Special events, even if they do not concern the fan itself (e.g. power failure, alarm)
