Dry Cleaning Process
1. Turn off power to the display.
2. Rub a dry, soft terry cloth horizontally across each row of LEDs.
3. Work from top to bottom. Clean only the area safely reachable from a lift or stage, and
then move on to the next section of modules. Take care not to damage LEDs or the plastic
louvers by catching the cloth on them.
6.5 Annual Inspection
Perform a yearly inspection of the display to maintain safe and dependable operation. Open
the display to inspect the cabinet interior and the components. Refer to Section 6: for
directions to access the interior.
1. Tighten or replace any loose fasteners.
2. Vacuum or carefully wipe away dust and debris around the vents / fans and inside
the cabinet.
3. Check for water intrusion or stains. Replace weather stripping. Tighten module
latches, place silicone sealant around areas where water might enter, and replace
damaged electronic components as necessary.
4. Check the paint for cracking and peeling and touch up with rust resistant enamel as
necessary.
5. Inspect the footings, tie points, and ground rods for corrosion, and make sure the
structural integrity and grounding connections are intact.
