Clean the face panels as needed, using one of the following methods.
Wet Outdoor Cleaning Method
Cleaning supplies:
• Water
• 5-gal bucket
• Automotive detergent
• 4' to 8' telescoping, soft automotive brush with bristles that are light to medium in
rigidity
• Several soft terry cloth towels
Cleaning process:
1�
Mix the automotive detergent and cold water in the 5-gal bucket at 1 oz detergent
to 1 gal of cold water. Distilled water is preferred, but not required.
2�
Dip the brush in the bucket of soapy water.
3�
Using brush strokes, wash the display from top to bottom.
Note:
Using a soap-dispensing brush with a low soap-to-water ratio eliminates
excess soap residue.
4�
Thoroughly rinse the display face with cold water under low pressure.
5�
Use a soft, dry terry cloth to dry and remove any excess water.
Pressure Wash Cleaning Method
Cleaning supplies:
• Pressure washer rated for 1,500 psi or less
• 45° (or more) spray nozzle
Cleaning process:
1�
Turn off power to the DMS.
2�
Spray face and sides of the DMS. Keep the nozzle of the pressure washer at least 2'
away from the display.
Note:
Use caution along areas of the display that contain seams, weather stripping,
or silicone. Ensure the pressure washer does not peel or rip any sealing
material.
