5 Description
5.1 Intended use
• Systemair axial fans of the series AR and AW are exclusively designed as a built-in device for conveying air according
to its technical data.
5.2 Incorrect use
Incorrect use refers mainly to using the fan in another way to that described. The following examples are incorrect
and hazardous:
• Conveying of abrasive, explosive, combustible air or
air with solid particles.
• Operation in an explosive atmosphere
• Installation outside without weather protection
• Operation without duct system or protection grille
• Operation with the air connections closed
5.3 Technical data
Max. ambient temperature [°C] see data sheet, available in our online catalogue.
Max. temperature of transported air [°C] see data sheet, available in our online catalogue.
Sound pressure [dB] see data sheet, available in our online catalogue.
Voltage, current, frequency, enclosure class, weight see name plate of the fan
The motor data can be found on the name plate of the motor, or in the technical documents of the motor
manufacturer.
The data on the name plate of the fan apply to "standard air" according to ISO 5801.

8.1 Electrical connection accessories
The following wiring diagrams show the electrical connections between accessories and
fans (with EC motor) or frequency converters (e.g. FRQ, FRQS, FXDM) which can be
controlled with a 0–10V signal. If you are not sure if your fan is equipped with an EC- motor
please see chapter 6 Name plate and type key, page 4.

Wire- colours of motors with carried out cables: +10V = red 0..10V = yellow GND = blue
MTP 10 MTP 20 MTV—1/10 EC-Basic
8.2 Protecting the motor
Note:
In fans equipped with an EC motor, there is no additional motor protection needed. The motor protection is
integrated in the electronics of 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!
Note:
Internally connected thermocontact: no external connection feasible or necessary.
Warning
Risk of injury because of sudden start up of the fan.
Thermost switches switch after triggering by excess temperature and closed independently after cooling
off. The fan can start up during this time.
♦Consider that the impeller can start up suddenly without resetting the fault.
♦Observe the 5 rules of electrical safety, see 2.3 5 rules of electrical safety, page 2.
8.3 Variable-speed fans
Warning
Resonant frequencies may result in increased vibration in certain speed ranges. These vibrations may
destroy components.
♦Only operate the fan outside these speed ranges.
♦Skip over these speed ranges.
♦Pass through these speed ranges so quickly that any vibration cannot exceed the admissible resonant
frequency values.
♦Observe the operating instructions of the frequency converter.
| 004

12 |Commissioning
Caution
Damage as a result of incorrect commissioning of the frequency converter.
♦Install the fan and frequency converter as near as possible to one another.
♦Use shielded cables.
♦All components (fan, frequency converter and motor) must be grounded.
♦We recommend using all-pole sinus filters.
♦Avoid running the fan via the frequency converter below 10 Hz.
♦Heating of the motor due to use of a variable frequency drive must be checked in the application by the
customer.
♦Never exceed the maximum impeller rotation speed indicated on the name plate of the fan.
9 Commissioning
Warranty claims can only be made if commissioning work is carried out correctly and written evidence thereof is
provided.
Safety information
♦Observe 2 Important safety information, page 1
Preconditions
♦Installation and electrical connection have been
correctly performed.
♦Before switching the fan on, check for externally
visible damage and ensure that the protective
equipment functions properly.
♦Inlet and outlet are free.
♦Cable glands are tight.
♦Safety devices have been fitted.
Commissioning of speed-controlled fans
Check the fan for vibrations at all normal operation speeds during commissioning. Determine and evaluate vibrations
on the housing and bearing areas in accordance with DIN ISO 14694 depending on motor power and positioning.
Measurable vibration velocities depend e.g. on following factors:
• positioning • bottom section/foundation state • flow conditions
The working point of the fan, as well as used external devices and accessories, also influence the running
characteristics.
Tests
Do the tests requested in the commissioning report (15 Commissioning Report, page 15)

For all other damage/defects, please contact Systemair.
11.2 Maintenance
Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is
provided.
We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are
specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning,
replacing defective components or other corrective measures. For traceability reasons, a maintenance plan must be
created which documents the work carried out. This must be created by the operator. If the operating conditions are
"extreme", the maintenance intervals must be reduced so that maintenance is carried out more frequently. Examples
of extreme operating conditions:
• Kitchen exhaust fans
• Fans for stables

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.

Safety information
♦Observe 2 Important safety information, page 1
Procedure
Keeping the fan clean extends its service life.
• Install a filter monitor.
• Change the filters of the ventilation system.
• Do not use steel brushes or sharp-edged objects.
• Do not use a high-pressure cleaner (steam jet cleaner) under any circumstances.
• Do not bend the fan blades when cleaning.
• When cleaning the impeller, pay attention to balance weights that have been positioned
• Keep the airways of the fan clear and clean them if necessary with a brush.
13 Deinstallation/dismantling
Deinstall and dismantle the fan in reverse order of installation and electrical connection.
14 Disposal
♦Ensure material is recycled. Observe national regulations.
♦The device and the transport packaging are predominantly made from recyclable raw materials.
♦Disassemble the fan into its components.
♦Separate the parts according to:
• reusable material
• material groups to be disposed of (metal, plastics, electrical parts, etc.)
