Rack Maintenance and Cleaning
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 Vacuuming Dimmer
Modules, page 43 ).
To clean your rack air filter:
Step 1: Open the dimmer rack door. The air filter is mounted on the inside of the door,
held in by a metal lip at the bottom of the door frame.
Step 2: Slide the filter upwards approximately 1/2 inch (1.25cm) until the base of the filter
clears the top of the metal lip.
Step 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.
Step 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.
N o t e : 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.
C A U T I O N : 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.
