DL.2 Digital Light User Manual

Like all high quality video projection units, the DL.2 fixture must be kept protected from 
excessive amounts of glycol fog, mineral oil, and smoke. DL.2 fixtures incorporate multiple air 
filters to reduce these risks to a minimum; however, the user must follow these guidelines to 
ensure continued operation of the fixture:

• Air filters (both fixture and projector) should be checked and cleaned on a regular basis. 

When used in a closed or fixed environment where fog or haze is used, we recommend at 
least a weekly check.

• Do not situate DL.2 in areas of high fog density such as directly in front of a fog machine or 

mineral oil hazer.

• Minimize the exposure of DL.2 to both glycol fog and mineral oil.

The DL.2 menu system displays a series of filter status and warnings to alert you when a filter 
needs to be cleaned or replaced. These appear in a large format that can be viewed from a 
distance. The Info_Status menu screen will include a detailed message concerning the large 
format Error/Warning filter message. The following messages will give you information 
regarding the status of the DL.2 filter system:

• Filter Missing Error: A filter not present or is not installed properly. Check and insert 

missing filter.

• Filter Service Warning: The filter system is not operating optimally and needs to be 

serviced soon.

• Filter Service Error: The filter system needs immediate servicing. Replace Filter.

For these and other Error/Warning messages, see Status Message Menu Display on page 219.

The DL.2 system utilizes multiple filters to protect the internal media server and projector.

• A filter is located on the side of the fixture base housing attached with velcro for easy 

removal and cleaning. Check this filter often for dust or debris that can be caused when 
using the DL.2 in environments with confetti or pyrotechnics. This filter is washable, but 
must be completely dry before re-installing.

• The Fixture head contains both a hepa filter and a prefilter

• The internal projector has two filters

Check the following warnings and cautions before servicing the filters:
