Care and maintenance

Safety instructions listed in Chapter 1.2 must be observed!

Prior to all work always ensure that the fan unit is isolated from the

power supply and secured against restarting!

In principle the devices are maintenance-free; the unit is not user

serviceable. Nevertheless all necessary maintenance work must be carried

out by qualified electricians!

Excessive deposits of dirt, dust, fats etc. on the impeller, motor, protective

grids and especially between housing and impeller are not allowed; as it can

lead to heavy imbalance in the impeller, overheat the motor or even block

the impeller. In those instances the device has to be cleaned.

In case of no longer use the unit must be serviced before operation.

Should be examined:



Secure mounting of the fan / replace if in doubt



Remove contaminant deposits



Mechanical damage, shut down the device, replace damage parts



Firm seating of bolt connections, loosen screws



Housing quality (cracks, brittleness of the plastic)



Overrunning of the impeller, the impeller doesn`t run freely, note

possible causes of failure in Chapter 8.1



Bearing noise



Vibrations – see Chapter 8.1



Power consumption according to the specifications on the type plate –

see Chapter 8.1

8.1

Decommissioning and disposal

Safety instructions listed in Chapter 1.2 should be observed!

During transportation safety instructions listed in Chapter 1.4 should be

observed.

Parts and components of the fan which have reached the end of their

lifespan, for instance because of the wear and tear, corrosion, mechanical

loading, fatigue and/or other effects that could not be directly discerned,

should be disposed in accordance with local and international laws and

regulations. The same applies to auxiliary materials such as oils, greases or

other substances. The conscious or unconscious re-use of used components

such as impellers, bearings, belts, etc. may endanger persons, the

environment as well as the equipment itself. Relevant local operating

regulations should be observed and applied.
