Daktronics Galaxy AF-3500 Series 46 mm - Manual (Page 25)

Maintenance 21
Notes:
 The weather stripping on the back edge of the module must be in good
condition to prevent water from entering the display.
 The module latches must be fully engaged to create a watertight seal around
the edge of the module. The module should be firmly seated against the
display when the latches are fully engaged.
6.3 Ventilation
Frequency of Inspection
Check the fans or filters every time you open the display, or once every three months, at a
minimum. Check more often if the display is located in a dusty or harsh environment, such
as along a gravel road.
The frequency of inspection will vary greatly from display to display, as no two display
setups are the same. Daktronics advises customers and service technicians to use their own
discretion when establishing an inspection schedule.
Filters
For Displays Using Natural Convection
Displays 40 and 48 pixels high use both rear vent panels and front filter trays.

2. Pull the filter upwards and out.
3. Inspect the filter and clean it if
needed.
4. Reinsert the filter in the vent
panel.

A filter tray is located below each intake
fan. Inspect the filters every time you
inspect the ventilation system or fans.
Clean or replace filters when necessary.
