Important safety information
2.1
Safety notes
Designers, installers and operators are responsible for the proper mounting and intended use.
•
As the operator, please ensure that the valid directives are complied with.
•
Only use the fan in a proper condition.
•
Provide generally prescribed electrical and mechanical protective devices.
•
During mounting, commissioning, maintenance and control, secure the place of mounting and the premises for possible preparations
against unauthorised access.
•
Observe rules for safe work.
•
Safety components must not be bypassed or put out of function.
•
Keep all the warning signs on the fan complete and readable.
•
Regularly instruct the personnel about safety-conscious behaviour.
NOTE
We have carried out a risk assessment for the fans. However, it can only apply to the fan itself. After in-stallation of
the fan, we recommend to carry out a risk assessment for the whole system. In this way, you have the guarantee
that there is no risk potential from the system.
2.2
Personnel
2.2.1
Mounting personnel
•
Mounting may only be carried out by trained, qualifi ed personnel.
2.2.2 Work on the electrical equipment
•
Work on the electrical equipment of the fan may only be done by a qualifi ed electrician or electrotechnically educated person. This
person must know the relevant safety rules to recognise and avoid potentially risks.
2.2.3 Personnel for operation, use, maintenance and cleaning
•
Operation, use, maintenance and cleaning may only be carried out by trained and authorized personnel. The operating personnel
must have appropriate knowledge about handling with the fan. In the case of a malfunction or an emergency they must react cor-
rectly and adequately.
2.3
Intended use
The fans are intended for installation in ventilation systems. They can be installed either in duct systems or as a free sucking fan over
a nozzle and a sucking side protection grid. A free blow-out and/or suction device via a contact-protection grid is possible following
consideration in the design.
•
The fans are suitable for extraction of clean air, air with a low dust and grease content, media up to max. density of 1,3 kg/m³.
•
The maximum permissible operating data on the name plate apply for an air density ρ = 1,2 kg/m³ (sea level) and a maximum air
moisture of 80 %.
•
The fans are suited for the ambient and conveying agent temperatures stated on the name plate.
2.4
Incorrect use
Above all, the incorrect use means using the fan in a way other than that described. The following points are incorrect and hazardous:
•
Extraction of explosive and combustible media
•
Conveying of liquids
•
Extraction of aggressive, dust or grease containing media
•
Operation in an explosion hazardous atmosphere
•
Operation without duct system or protective guard
•
Operation with the air connections closed
