Operational Use 

Construction of the device assures reliable function  without continuous routine technical super-
vision.  

Periodically, it is important  to check systematically the mechanical and electrical 

connections

the state of grounding  and also to provide efficient cooling to the motor

 

For incorrect function is considered: 
a

/

 

forwarding the media exceeding the admissible tempe60

b

/

 

conveying aggressive media 

c

/

 

conveying the media of high dustiness or with high pollution particles content, 

d

/

 

use of the fan in areas where the ambient temperature e40

C. 

 
Consequences of incorrect use: 
a

/

 

damage of bearings 

b

/

 

damages caused by corrosion 

c

/

 

loss in balance of the rotating elements 

d

/

 

vibrations 

e

/

 

deformations 

f

/

 

damages caused by friction 

 
Risks which can occur due to improper use

  

–  damages or other defects caused by: 

 

burst of the impeller 

 

break of the shaft 

 

fatigue crack of the material 

 

ignition and explosion caused by sparks 

 
In case when any symptoms of incorrect device function (noise increase, vibrations, reduced  
flow efficiency)  are noticed,  the device should be disconnected from the power system, and 
thoroughly revised  (with reference to the reason of  disturbance during the operation). 

 

 

According to 2014/34/EC Directive, in case of any repair or replacement  

of a spare part 

– put a notice on an additional plate and in the enclosed documentation  

(

a register of repair activities, etc.

). 

 This is the duty of User!
