Maintaining and Cleaning the Rack

Proper air flow is necessary for your Sensor3 rack to function properly and consistently. Perform the
following procedures regularly to keep dust and foreign debris from impeding the proper function of
your rack.

Cleaning Rack Air Filters

Clean the air filter in the Sensor3 rack door a minimum of every six months, more often if your system
operates in a dusty environment. This will also provide an opportunity to inspect the dimmer module
air vents and clean them if necessary (see
To clean your rack air filter:
1: Open the dimmer rack door. The air filter is mounted on the inside of the door, secured by a
metal lip at the bottom of the door frame.
Note:
2: Slide the filter upwards approximately 0.5 in. (1.25 cm) until the base of the filter clears the top
of the metal lip.
3: Pull the bottom of the air filter out and
away from the door far enough to clear the
retaining lip and slide the filter downwards
and out of the door frame.
4: In an area away from your dimmer rack
and other dust-sensitive equipment,
remove all dust or debris from the filter
using either compressed air or a vacuum.
CAUTION:
5: Slide the top of the filter up into the slot at the top of the door until the base clears the metal
retaining lip at the bottom.
6: Ease the filter back into the door frame and carefully let it drop back into place.

Sensor3 48-module racks have two filters, one stacked on top of the other with a
retention bar in the middle of the rack. Remove the top filter screen before removing
the bottom one.
You may rinse the filter
under cold tap water, but it
must be completely dry
before you reinstall it.
Do not use soap or other
chemical cleaners to clean
the filter. They may damage
the filter screen.
For Sensor3 48-module racks, install the bottom filter first. The top filter rests on the
top edge of the bottom filter.
