7. 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, si-
lencers and electric connection
• Cleaning
– Internal with compressed air or
vacuum cleaning
– External with a wrung cloth. No
water must get in the electric sys-
tems or the acoustic insulation.
Keep a journal of all measured values
and observations for each fan.
8. Sound
The fan sound emission depends on in-
stallation and operating conditions,
hence no general data can be given.
Refer to the product catalogue and the
technical fan specifications.
9. Safety
The jet fans must be installed according
to Novenco’s, the current and the local
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 in-
stallation 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 installa-
tion. For example, by mounting wire
guards on inlet and outlet.
10. Spare parts
