Maintenance and cleaning

The DMX24DIM or DMX24DIM-2U's fan intake on the front panel and the exhaust ports on the left
side of the enclosure should be cleaned periodically (see photos below). The frequency of cleaning
depends upon the working environment and the amount of time the dimmers are running.
Compressed air and a soft cloth should be used to remove excess dirt and lint. Power to the
DMX24DIM or DMX24DIM-2U must be disconnected while cleaning.

Fan operation

The fan in the DMX24DIM or DMX24DIM-2U will run any time any of the levels of any dimmer in the
pack is above 0%. The fan will continue to run for about 30 seconds after all dimmers are at zero.
