OPERATION

 

7.1 Initial commissioning  

Before  running  the  unit  for  the  first  time,  be  sure  that  all  guards,  motor  mountings  and 

electrical covers are secure, installation and electrical connection are done properly, internal 

wiring is kept away from the fans and the fans can rotate freely. 

Make sure that all the mechanical connections are done in accordance with the rules. Piping is 

consistent with the guidelines. Before the start-up you may run the fans individually to make 

sure that they are running properly. Turn on the fluid valves and let the fluid flow right before 

running  the  fans.  In  case  you  may  encounter  any  problem  or  disfunction  please  refer  to  the 

manufacturer for the resolution of the problem.   

 

7.2 Regular commissioning 

If the product is stationary for long periods in a humid atmosphere, the fans must be switched 

ON  for 

minimum  of  four  hours  in  every  month

  to  remove  any  moisture  that  may  have 

condensed within the motors. 

While the fans are running, anything that could pass through the finger guards, like a piece of 

cloth or long hair, must be kept away from the fans. 

  Switch on the main power switch 

  Make sure that the fluid is flowing inside the pipes.
