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 16)

Troubleshooting
Problem Possible causes
Remedy
Fan does not run
smoothly
Impeller imbalance
Rebalancing by a specialist company if possible,
otherwise contact Systemair.
Soiling on the impeller Clean carefully, rebalance
Impeller rotates in wrong
direction.
AC motor
Change direction of rotation (swap two phases in case of
a 3– phase motor).
EC motor
Contact Systemair
Deformation of impeller due to
excessive temperature.
Ensure that the temperature does not exceed the certified
value/Install new impeller.
Vibrations, oscillations
Check the installation of the fan.
Fan operation in resonant
frequency range
Consider chapter 8.3 Variable-speed fans (Frequency
converter / EC motor), page 10
