5.1.3 Fan Filters
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.

Disconnect power to the unit before beginning the subsequent steps
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.
