Section 5: Replacing Display Components
5.1 1000 Series Specific Procedures
Note on Removing Modules
The 1000 series displays are front access only. Refer to Section 4: for instructions on
removing a module from the front of the display.
Fine Mesh Screen
1. Cut out the existing fine mesh screen with a utility knife.
2. Align the rivet clearance holes on the grill cover (OM-353962) over the existing rivet
heads.
3. Fasten the grill cover into place with #10 TEK screws.
Note: TEK screws go into the small holes. There are two holes on each end of the grill
and two in the middle section.
Metal Frame Filter
Before May 2007, the 1000 series displays used metal frame filters. Release five of the 1000
series introduced the green filter, which is now a standard part on displays after May 2007.
The green filter retrofit kit (0A-1413-3900) was introduced in April 2007 and should be used
during routine filter service on 1000 series displays that still have metal frame filters.
To replace the metal frame filter, follow the steps below.
1. Remove the metal frame filter by lifting up and pulling out from the bottom of the
filter.
2. Put the green filter in the filter holders.
3. Put the end of the filter bracket in the corner of the bottom holder, in between the
filter and the outside flange of the bottom holder.
4. Rotate toward the center of the filter to get under and in front of the top holder.
5. Rotate the filter bracket up into a vertical position. Be sure not to rotate too far, or the
channel will slip out.
Optional Thermostat Addition to Digital Billboard Fan Filter Displays
Daktronics recommends adding the thermostat to all 1000 series fan filter displays. Doing so
may prolong fan life and reduce operation costs.
Use Thermostat Addition Kit 0A-1413-3050.
To install a thermostat, follow the steps below.
