8.1 Cleaning TF-20 tiles
Why clean TF-20 tiles?
Due to outdoor use the TF-20 tile is exposed to all kinds of weather conditions. Sand, dust, smog and other dirt adhere on the TF-20
tile and therefore the visual performance of the TF-20 display is reduced. That’s why cleaning the TF-20 tiles is recommended at
regular intervals.

Cleaning LED’s and shaders.
Always clean all tiles of the LED-wall to avoid brightness differences between cleaned and uncleaned tiles.
Necessary tools
• Vaporizer with a window cleaning product.
• Soft hand brush with long hair (recommended 4 cm pure pork hair).
• Garden hose with a spray nozzle.
• Compressed air.
How to clean TF-20 tiles?
1. Seal up the data and power sockets using a power and data linking cable. Make sure that all plug holder clamps are locked fi rmly.
2. Vaporize through different directions the window cleaning product on the shaders and LED’s.
Caution: Do not use industrial grease removers. Use only materials or chemicals that are inert, nonabrasive, noncorrosive
and non-marking.
3. Brush down all dirt of the LED’s and the shaders using a soft hand brush.
Caution: Do not use a hard bristled brush.
4. Wash away the remaining soap with plenty of fresh water.
Caution: Do not submerge the tile fully or partly in water or other liquids.
5. Repeat from step two until the tile is clean.
6. Blow the surface dry with compressed air.
The TF-20 tiles can also be cleaned while they are mounted. A solid scaffold or Z-lift is required to do so. Start
cleaning from top row to bottom row using the above procedure.
