Centrifugal fans – GigaBox GBW EC.. / GBD EC..
– Protection against accidental contact
- Remove assembly residuals and foreign parts from the ventilation room.
- Test unhindered running of the impeller.
- Check if cable gland is tight.
- Do the connection data agree with the data on fan rating plate
– Commissioning:
- Put motor into operation by switching the enable signal.
⇒ The fan must run smoothly at each speed.
- Check even rotation and control behaviour by slowly increasing the setpoint specification

Cleaning and Maintenance

All maintenance and servicing work must only be carried out by qualified personnel and all relevant safety
regulations and guidelines must be observed!
m
Ensure that the unit is isolated from the mains and is secured against restarting with an isolator switch
before maintenance and servicing work!
– Impeller must stand still
– Only clean unit with a damp cloth.
– Excessive deposits of dirt, dust, grease and other materials on the impeller, motor and between casing and impeller
must be avoided and prevented by periodical cleaning.
– For maintenance purposes inspection doors and access openings must be provided in the duct system in a suitable
place.
– The motors have maintenance-free, long lasting, greased ball bearings.
6.0 Information – Fault causes
The triggering of the integrated electronic temperature monitoring system can be caused by:
– fan not running at highest speed
– fan permanently running at highest speed
– the build-up of dirt, stiffness of impeller and/or ball bearing failure
– air flow temperature too high
Abnormal noises can be caused by
– incorrect direction of rotation
– worn out ball bearings
– lack of vibration decoupling to other buildings and ducting systems
Vibrations and oscillation can be caused by
– unbalanced or dirty impellers
– lack of vibration decoupling to other buildings and ducting systems
Extreme reductions in performance can occur
– in case of incorrect direction of rotation
– if resistance to air stream through ducting and accessories (grilles, shutters, filters etc.) is higher than planned.
