General information | 1 General information 1.1 Warning symbols Danger Caution Direct hazard Failure to comply with this warning will lead directly to death or to serious injury. Hazard with a low risk Failure to comply with this warning may lead to moderate injuries. Warning Important Potential hazard Failure to comply with this warning may lead to death or serious injury. Hazard with risk of damage to objects Failure to comply with this warning will lead to damage to objects.
2 | Important safety information Warning Regarding the choice of material, the EX fans fulfil the requirements of Standard DIN 14986 (Construction of fans for use in potentially explosive atmospheres) as a result of specific protection measures in areas of potential contact between rotating and stationary components (rotor/intake nozzle). A safety clearance to the intake nozzle is guaranteed for the rotating part.
Warranty | 3.1 Personnel The fan may only be used by qualified, instructed and trained personnel. The persons must know the relevant safety directives in order to recognise and to avoid risks. The individual activities and qualifications can be found in Table 1 Qualifications, page 3.
4 | Delivery, transport, storage 5 Delivery, transport, storage Safety information Warning: Risk from rotating fan blades ♦ Prevent access by unauthorised persons by safety personnel or access protection. Warning: Suspended loads ♦ Do not walk under suspended loads. ♦ Make sure that there is nobody under a suspended load. Delivery Each fan leaves our plant in an electrically and mechanically proper condition. We recommend transporting the fan to the installation site in the original packaging.
Description | 6 Description 6.1 Intended use Indended use PRF and PRF EX • The fans are intended for installation in ventilation systems. • The fans are exclusively intended for extract air applications. • The fans have been developed and built to convey air with the simultaneous presence of corrosive gases/vapours. Indended use PRF EX • The EX fans are not ready-for-use products, but have been designed as components for ventilation equipment, machines and systems.
6 | Description 6.4 Chemical components The standard plastic types used are polyethylene (PE) and polypropylene (PP). As a matter of principle, the rotor material is the indicator for the selection. Note: The list “COMPATIBILITY WITH CHEMICAL AGENTS” is available in our online catalogue. This list has been produced to the best of our knowledge, but we cannot guarantee the correctness of all statements. Examination of the media to be transported is a matter for the plant operator.

Installation | 10 Installation Safety information Warning: Danger from falling fan or fan parts. ♦ Check the surface before installation for load bearing capacity. ♦ Consider all static and dynamic loads when selecting hoisting equipment and fastening components. General safety information ♦ Fans installed in areas where personnel access regularly must be equipped with a splinter guard, please contact Systemair.
12 | Electrical connection 10.1 Installation positions The installation is possible in any mounting position. 10.2 Lightning protection device ♦ If the risk assessment shows that there is the risk of an atmospheric discharge, lightning protection measures must be taken. For reasons of operational safety, provide for a suitable lightning protection system according to country specific directives (e.g. DIN VDE 0185).
Electrical connection | 11.1 Protecting the motor Important Damage to motor due to overcurrent, overload or short circiut. ♦ Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault occurs, the motor cannot switch on again automatically after it has cooled down. ♦ Motor lines and temperature monitor lines should be laid separately on principle. ♦ Without thermal protection: Use a motor protection switch! 11.
14 | Commissioning 12 Commissioning The system operator is responsible for the correct operation of the fan and/or the system! Warranty claims can only be made if commissioning work is carried out correctly and written evidence thereof is provided. It is recommended to fill out the commissioning report 18 Commissioning Report, page 20. 12.1 Safety information ♦ Commissioning may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 3.
Operation | 13 Operation 13.1 Safety information Danger Risk of ignition of a potentially explosive gas/air atmosphere! When commissioning the EX fan, the fundamental information from DGVU 113-001 (explosion protection rules (EX-RL)) and TRGS 727 (avoidance of risk of ignition as a result of electrostatic charges) must be known. ♦ Do not open or tip the fan if an explosive atmosphere exists. Warning: Hazard from electrical voltage or moving components.
16 | Troubleshooting/maintenance/repair 14 Troubleshooting/maintenance/repair Safety information ♦ Observe 3 Important safety information, page 2 ♦ Pay attention to the safety data sheet of the chemical substances transported with the fan.
Troubleshooting/maintenance/repair | Troubleshooting cont'd Thermal contacts/ resistors have triggered Fan does not reach nominal speed Motor does not rotate Electronics/motor overheated Impeller rotates in wrong direction. Change direction of rotation (swap two phases in case of a 3– phase motor). Contact Systemair Missing phase In case of a 3 phase standard motor (not EC), check if all 3 phase are present.
18 | Troubleshooting/maintenance/repair Activities cont'd Check the screwed connections for damages/defects and check that they are firmly seated. X Check the fan intake is free from contamination. X Check that the fan and its components are being used correctly. See normal operating conditions X See normal operating conditions X Check the current consumption and compare this with the rated data.
Cleaning | 15 Cleaning 15.1 Safety information ♦ Cleaning may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 3. ♦ Observe the 5 rules of electrical safety, see 3.3 5 rules of electrical safety, page 3. ♦ The impeller must be at a standstill. ♦ Pay attention to the safety data sheet of the chemical substances transported with the fan. Warning Risk of ignition as a result of electrostatic charges.
