5.  INSTALLATION 

The fan must be installed according to the air direction label on the fan. Before the start of assembly, 

examine manually whether the fan wheel runs freely. Before installation, check the minimum air gap between 
the blade tip and the housing according to the following table. The fan can be mounted parallel to the wall 
without any accessories. For mounting, it is recommended to use the bolt holes in the housing.During 
assembly, secure the assembly area. Take precautions for any access by unauthorized persons. The fan 
should be installed in a way that makes service and maintenance easy. The ground connection must be 
made correctly. 

The electrical connection will be made by the customer and D type cable gland must be used. Electrical 

cables should be selected according to EN 60079-14: 2014 standards and the contact person must be 
trained in accordance with ATEX regulations and relevant standards. 

 
Note: If there is no cable gland on the motor, ATEX certified type D cable gland should be used when 

making electrical wiring.
