7. Troubleshooting
Locate and identify problems with and
around the fans in as much details as
possible, before f.x. calling for service or
ordering parts. Things to look for
include the following.
Lacking performance
• Inlet or outlet blocked
• Auxiliary fans stopped
• Motor defective
• Motor disconnected
• Electric connection defective
• Wrong direction of rotation
Noise and vibrations
• Motor bearings defective
• Rotor in imbalance
• Rotor worn or damaged
• Loose components
• Rotor blades with different angles
(loose blades).
• Fan operates in the stalling area,
which may result in breakdown.
Correct errors – see “Lacking
performance”.
8. Inspection and test
Extent of inspection
• Measure power consumption at full
and half speeds
• Vibration measuring on fan casing
(outside motor)
• Check of fan suspension
• Visual inspection of rotor, casing,
silencers and electric connection
• Cleaning
- Internal with compressed air or
vacuum cleaning
- External with a wrung cloth. No
water must get in the electric
systems or the acoustic
insulation.
Keep a journal of all measured values
and observations for each fan.
9. Sound
The fan sound emission depends on
installation and operating conditions,
hence no general data can be given.
Refer to the product catalogue and the
technical fan specifications.
10. Safety
The jet fans must be installed according
to Novenco’s and the current safety
regulations. At a minimum these include
EN 13850.
It is recommended to review and revise
safety procedures regularly.
Safety check
• Test if safety procedures and the
installation work correctly.
• Check if safety regulations have
been changed and if the installation
needs revising.
• Consider taking additional
measures to improve the safety of
the installation. For example, by
mounting wire guards on inlet and
outlet.
11. Reference documentation
Please refer to the below documents on
the Novenco website for further

12. Disposal
Dispose of fans suitable for scrapping in
environmentally safe ways and in
accordance to current regulations.
The fans and especially the electric
motors contain a wide range of
materials, which can all be recycled.
Make sure worn-out motors and fan
parts are disassembled and recycled for
the benefit of the environment.
