3.1

 

MOUNTING/FASTENING 

 
The pump should be mounted and fastened on a solid base plate or wall mounted frame so 
distortion is avoided. 
          
When installing the pump check that it is earthed to avoid an electrical potential in the pump. 
 
The max. permissible loads on the flanges stated in paragraph 2.2 are to be observed. 

 
   At installations pumping hot or very cold liquids, the operator must be aware 

that it is dangerous to touch the pump surface and, consequently, he must take 
the necessary safety measures. 

 

3.2

Wiring to be carried out by authorised skilled workmen according to the rules and 
regulations in force.
