♦ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor. ♦ Safety elements may not be dismantled, circumvented or deactivated. ♦ Only use the fan in operational condition, if in doubt contact Systemair. ♦ Provide generally prescribed electrical and mechanical protective devices.
Further prerequisites are a completed maintenance plan with no gaps and a commis- sioning report. Systemair will require these in the case of a warranty claim. The commissioning report is a component of this document. The maintenance plan must be created by the operator, see section 11.2 Maintenance.

| Description Description General • The fan conveys air in an axial direction from the intake side via the electric motor to the outlet side. (except AXCBF). • The electrical connection is made through a terminal box installed on the outside of the housing (except AXCBF). Sensors (optional) Sensors can be connected to the fan to monitor the roller bearings and for vibration monitoring.

♦ Consider below guideline for installation positions. Note: • Order process (Systemair configurator): If the type of installation is e.g. "SO" (vertical installation, >= IEC 160), a suitable motor is automatically used (in this case with different bearings). • Please contact Systemair if a position marked with a “red-cross” is required for an existing fan.
Installation | Distance from the wall/ceiling ♦ Ensure enough distance between the ceiling and the wall. • The duty point may not be reachable. • The fan may make noise. If the minimal distances are not possible for construction min. 1xD reasons, install a deflector in front of the fan in a way that ensures a direct, smooth and constant flow of air.
7.2.5 Air gap Ensure that the air gap between the housing and the impeller is complied with. ♦ Contact Systemair ♦ Do not install the fan if the gap in the table is not complied with. ♦ Check if the air gap complies with the table.5.1.3 Air...

♦ Operation at frequencies below 10Hz and above 60Hz must be avoided. ♦ Smoke extract axial fans should be operated at maximum mains frequency. If the mains frequency is to be exceeded in individual cases, please contact Systemair in advance. ♦ Starting time: min. 60 sec.
The working point of the fan, as well as used external devices and accessories, also influence the running characteristics. Adjusting the blade angle If the working point of the fan has to be changed and it is necessary to adjust the blade angle, please contact Systemair! Operation Safety information Warning: Hazard from electrical voltage or moving components.
Remove the blockage blocked Check the cooling impeller (if used), measure the motor Motor overheated winding (if possible) / contact Systemair Thermal contacts/ Change direction of rotation (swap two phases in case of a 3– Impeller rotates in wrong resistors have phase motor) direction.
Troubleshooting/maintenance/repair | Note: For all other damage/defects, please contact Systemair. Defective safety-relevant fans (for Ex and smoke extraction applications) must be replaced completely. 11.2 Maintenance Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is provided.
5) Extension of maintenance intervals ♦ Systemair axial fans withoutVDD need to be maintained after a 20,000/40,000 hours of operation (depending on the type of motor bearing) or at the latest after 5 years. ♦ The maintenance intervals can be prolonged using VDD, as shown in the table below.
Cleaning | 11.5 Spare parts ♦ Use original spare parts from Systemair only. ♦ When ordering spare parts, please specify the serial number of the fan. This can be found on the name plate. Cleaning Safety information ♦ Cleaning may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 2.
