Important Safety Information - SystemAir FSL Betriebsanleitung

2. Important safety information
2.1 Safety notes
Designers, installers and operators are responsible for the proper mounting and intended use.
• 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 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, qualified personnel.
2.2.2 Work on the electrical equipment
• Work on the electrical equipment of the fan may only be done by a qualified electrician or electrotechnically edu‐
cated 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 oper‐
ating personnel must have appropriate knowledge about handling with the fan. In the case of a malfunction or an
emergency they must react correctly and adequately.
2.3 Intended use
DVV 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. With FSL flaps mounted as accessory has the DVV fan the
same rating as the basic unit (F400 or F600). DVV with FSL flaps is suitable for installation on not heated buildings with
snow load requirement SL 1000. In case of fire, smoke extract fans DVV with FSL flaps are used to exhaust hot air and
smoke from buildings. They can be also used for normal daily ventilation under normal operating temperatures (up to
120°C). FSL flaps are not heat insulated and not tight. DVVI fans (with silencer) cannot be serial equipped with acces‐
sory FSL.
We recommend to order fan with factory mounted FSL; however, it is possible to mount it subsequently.
• DVV fans with FSL 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 and permissible moisture of max. 95 %.
• 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 %.
• DVV fans with FSL are suitable for the following media temperature limits at an ambient temperature from ‐20°C
to +40°C:
