RAQ™ 21 

Periodically, you may find it necessary to clean fan filters built into the back of the 
C

Y

RAQ’s enclosure. Cleaning frequency is largely based on environmental and other 

conditions immediately surrounding the unit. Since most applications require the C

Y

RAQ 

to be rack or panel-mounted, the engineers at CyberResearch, Inc. designed a filter 
system users can maintain without dismounting the display, disassembling the unit, or 
removing the fan filters from the enclosure.  
 

To clean the fan filters: 

1.  Power off the unit using the On/Off switch. 
2.  Unplug the unit’s AC power. 
3.  Gain access to the rear of the unit. 
4.  Carefully run a vacuum hose (using a crevice attachment is ideal) over the 

protective fan filter screens (Figure 40) to remove dust and debris from the 
protective covers and underlying fan filters themselves. 

5.  When done, restore power to unit.
