Air Filter
Length of time between air filter replacements depends on the
environment in which the VideoWall is operated. Air filter cleanliness
should be periodically checked and the air filter replaced when dirty, at
a minimum of every 3,000 hours of operation. An excessively dirty air
filter can block air flow to the optical assembly and cause excessive
heat buildup inside the VideoWall. The air filter is most easily accessed
from the rear of the VideoWall by first removing the lamp access cover.
CAUTION
Use care when removing the air filter to avoid causing
accumulated dust to fall into the optical assembly.
