1. Make sure that there is tension to the fan.
2. Cut the tension and verify that the impeller is not
blocked.
3. Check the LED flashing code. (RKB 600x350 EC
up until RKB 1000x500 EC). For more information
see page 29-30.
4. If nothing of this works, contact your fan supplier.
5. If the fan is returned to the supplier, it must be
cleaned, the motor cable undamaged and a detailed
nonconformity report enclosed..

• Before service, maintenance or repair begins, the fan
must be tension free and the impeller must have
stopped.
• Consider the weight of the fan when removing or
operning larger fans to avoid jamming and contu-
sions.
• The fan must be cleaned when needed, at least once
per year to maintain the capacity and to avoid unba-
lance which may cause unnecessary damages on the
bearings.
• The fan bearings are maintenance-free and should
be renewed only when necessary.
• When cleaning the fan, high-pressure cleaning or
strong dissolvent must not be used.
• Cleaning should be done without dislodging or
damaging the impeller
.
• Make sure that there is no noise from the fan.

When starting, make sure that:
• the current does not exceed more than +5% of what
is stated on the label.
• the connecting voltage is in b6% to –10%
of the rated voltage.
• no noise appears when starting the fan.
H O W T O H A N D L E
• The fan must be transported in its packing until in-
stallation. This prevents transport damages, scrat-
ches and the fan from getting dirty.
• Attention, look out for sharp edges and corners.
•
Attention!
Temperatures up to 85 °C can be pre-
sent on the controller housing.
•
Waiting period of at least 3 minutes!
Because of internal capasitors, danger of death exists
even after switching off the device through directly
touching the energized parts or due to parts that
have become energized due to faults. The controller
housing may only be removed or opened when the
power line has been switched off and a period of
three minutes has elapsed since switching it off.
• Avoid extreme heat or cold (temperature range for
storage and transport.
• Avoid prolonged storage; we recommend a maxi-
mum of one year (consult the manufacturer before
starting if stored for longer).
