Operational Use 

The construction do not require any additional maintenance after the start-up.  If the place of 
operational use is changed 

– repeat the steps as mentioned in Section 6

,

  

according to the in-

stalling and adapting the ventilation system to the new conditions. 
In case when any defective function of the unit occurs (e.g. improper noises or the outlook of 
the device)  follow steps as in Section 8.

Maintenance 

In the aspect of operational use, the fan construction guarantees its efficient function without 
continuous routing 

everyday

 technical supervision. Nevertheless, to obtain proper function of  

the device 

and to follow the safety rules

manufacturer suggests execution of technical re- 

visions on regular basis

.  During the inspection check the function 

of the fan 

and the techni- 

cal state of its elements. 

 

 

 All the activity connected with

 power supply ought to be carried out by 

an authorized person with testified electrical qualifications. The appliance ought to be 
disconnected from the power supply system during that time. 

(

the exemption from this are 

activities

 carried out 

on the running fan, under strict

 obser- 

ving the Occupational and Health Safety rules 

– e.g. vibration  measurement

). 

Before the maintenance on the fan, necessarily disconnect it from the power supply system 
and wait until the impeller stops its rotations. 
 

Within the scope of inspection execute following activities

● 

check and tighten the mechanical and electrical connections, 

● 

examine the mountings of the motor and the fan,  important is that the clearance between  
the inlet and the impeller is even within the whole circumference. 

● 

remove the impurities accumulated inside the fan,  eventually clean it from pollutants  
originating from the conveyed medium. 

 
During the maintenance activities follow strictly the rules of Occupational Health and Safety, 
in order not to cause hazard to workers / people in the vicinity.
