12. Cooling Fan 

 

12.1  Fan inspection 

 

Inspect the fan (clean the filter) by following the steps below.

 

1)  Turn OFF the controller and remove the front panel.    Do not disconnect the cables 

from the back side of the front panel. 

2)  Pull out the fan’s filter.    It is attached to the back of the front panel.    Clean it by vac-

uum cleaner or wash and dry. 

Fan safety cover

Filter

 

3)  Turn ON the controller, with the front panel off.    Check that the fan runs properly. 

4) Install fan’s filter to its original position, and install the front panel on the controller.
