Ventilation System
Galaxy
®
Large Matrix GS6 series displays are equipped with a ventilation system that
helps keep internal components at operable temperatures. Galaxy
®
Large Matrix GS6
series displays are rear ventilated, so the display support structure must allow adequate
space or air movement for proper ventilation. Refer to the display
Shop Drawing
for
ventilation requirements.
Fans help bring fresh air into the display while exhausting hot air through the upper vents.
Fans are controlled via a thermostat in the display cabinet. The thermostat is equipped
with a bypass button for testing fan operation. Replace fans that are not working
properly.
Display Face Cleaning
Wet Cleaning Process
1�
Turn off power to the display.
2�
Mix a mild, non-abrasive, non-petroleum-based detergent and cold water. Use one
ounce of detergent to one gallon of cold water.
3�
Saturate a light/medium duty cleaning brush with the soapy water.
4�
Use horizontal brush strokes to loosen and remove dirt and grime, washing the display
from top to bottom. Use light pressure so as not to damage the LEDs. Clean only an
area that is safely within reach from a lift or stage, and then move on to the next
section of modules.
5�
Rinse the display face with generous amounts of cold water under low pressure. A
spot-free rinse agent can be used to reduce water spots.
6�
Use soft, dry terry cloth to dry and remove any excess water. Take care not to
damage LEDs by catching the cloth on them.
Dry Cleaning Process
1�
Turn off power to the display.
2�
Rub a dry, soft terry cloth towel horizontally across each row of LEDs. Make four
passes per row of LEDs before moving to the next row of LEDs. Work from top to
bottom safely within reach from a lift or a stage. Take care not to damage LEDs or
the plastic louvers by catching the cloth on them.
