8.2 

Maintenance and Service Intervals

 

 
Preventative maintenance of the pre- and post-filter element, and desiccant material is required.   
 
The controller monitors the dryers operating hours and will activate the maintenance alarms after the following intervals: 

 

360 Days: Amber Service Light  

 

400 Days: Red Service Light 
 

The dryer system should be check for items that require standard replacement and maintenance such as: the filter 
elements, exhaust silencers, and desiccant material. 

 
NOTE: The maintenance alarms (reminders) do not change the operation of the controller in any way. 
 
8.3 

Fuses

 

 
One safety fuse is fitted on the electronic board, in positions F1. The fuse protects all circuits the electronic board of the 
BEKOMINI controller.  The replacement fuse type is: 
 

 

T1A type Radial lead fuse, PCB style 

 

 

  The fuses can break if there are any problems with the dryer.  In which case, only a certified technician 

can replace the fuse, but only after solving the problem that caused the malfunction first.  Refer to 
Section 9, ‘TROUBLESHOOTING GUIDE’.
