4.4 Storage
♦ Store the fan in the original packaging in a dry, dust-free location protected against weather.
♦ Avoid the effects of extreme heat or cold.
Important
Hazard due to loss of function of the motor bearing
♦ Avoid storing for too long (recommendation: max. 1 year).
♦ Check that the motor bearing functions properly before installation.

8.1 Safety information
Danger: Electrically charged device
Risk of electric shock
♦ When working on an electrically charged device,
stand on a rubber mat.
Danger: Faulty insulation
Risk of electric shock
♦ Use only cables that meet the specified installation
regulations for voltage, current, insulation material,
capacity, etc.
♦ Route cables so that they cannot be touched by any
rotating parts.
Warning: Danger from electrical voltage!
♦ Observe the 5 rules of electrical safety, see 2.3 5 rules of electrical safety, page 2.

♦ Wear protective equipment during all work in the vicinity of the fan, details see 2.2 Personal protective equipment,
page 2.
♦ The rotor is not protected by insulation nor grounded to earth in accordance with DIN EN 60204-1, and for this rea-
son the system constructor must provide protection in the form of obstacles or a location outside the handling area
in accordance with DIN VDE 0100-410, Attachment B, before the motor is connected to a power source.
♦ Do not use metal compression-gland fittings with plastic terminal boxes. - Danger of an electric shock if connection
is not made correctly!
♦ Wait five minutes after disconnecting the voltage at all poles before opening the device.
Danger: Voltage on the device
Risk of electric shock

♦ Check the protective earth.
Danger: Electrical charge (>50 μC) between phase
conductor and protective earth connection after
switching off supply with multiple devices connected in
parallel.
Risk of electric shock
♦ Ensure sufficient protection against accidental
contact. Before working on the electrical hookup,
short the supply and PE connections.
Warning: Danger due to electrostatic influence on medical implants (e.g. cardiac pacemaker)!
♦ Persons with medical implants (e.g. cardiac pacemaker) should keep enough distance to the fan.
8.2 Preconditions
♦ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor.
♦ Safety elements may not be dismantled, circumvented or deactivated.

a way that allows the cover of the terminal box to be
closed without resistance.
♦ Use all of the locking screws.
♦ Insert the screws by hand to avoid damaging the
thread.
♦ Tighten all glands well in order to guarantee
protection class IP.
♦ Screw the lid of the terminal box/inspection switch
evenly tight.
♦ Connect the cable end in a dry environment.

8.6 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.
8.7 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.
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.
It is recommended to fill out the commissioning report 15 Commissioning Report, page 15.

Note:
For all other damage/defects, please contact Systemair. Defective safety-relevant fans (for Ex and smoke
extraction applications) must be replaced completely.
11.3 Maintenance
Defective motor winding
Improperly aligned drive motor
Control units (if used) such as
frequency converter or
transformer are set incorrectly.
Mechanical blockage Remove the blockage.
Faulty supply voltage Check the supply voltage, re-establish the voltage supply.
Faulty connection
Temperature monitor has
responded.
Insufficient cooling Improve cooling.
Overloaded motor
Ambient temperature too high Check if the correct fan is used for your application.
Contact Systemair
Contact Systemair
Correct the settings of the control units.
Disconnect from the power supply, correct the
connection, see circuit diagram.
Allow the motor to cool down, find and resolve the cause
of the fault.
Check if the correct fan is used for your application.
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
• Stall fans

11.4 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.
12 Cleaning
12.1 Safety information
♦ Cleaning may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 1.
♦ Wear protective equipment during all work in the vicinity of the fan, details see 2.2 Personal protective equipment,
page 2.
♦ Observe the 5 rules of electrical safety, see 2.3 5 rules of electrical safety, page 2.
♦ The impeller must be at a standstill.
12.2 Procedure
Important
Keeping the fan clean extends its service life.
♦ Install a filter monitor.
♦ 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.)
