6-5 Air filter
NOTE
• Please replace the air filter when it is damaged or too dirty to be cleaned, and also when the lamp
is replaced.
• Only reset the FILTER TIME item when you have cleaned or replaced the air filter so that the FILTER
TIME remains accurate.
• The projector may display the message “CHECK THE AIR FLOW” or automatically turn the power off in
order to prevent the internal heat level from rising.
WARNING
• Do not take care of the projector during use or immediately after use. Handling while the projector is hot
could cause burn and/or projector malfunction. Before maintaining, make sure that the power switch is off,
that the power cord is unplugged, and that the projector is adequately cool.
• Use only the specified air filter type. Do not use the projector with the air filter or the filter cover removed.
Doing so could cause fire and/or projector malfunction.
• The air filter should be cleaned periodically. If the air filter becomes blocked by dust or other debris, the
internal temperature will rise, which could cause burns, fire and/or projector malfunction, or reduce the
lifetime of the projector.
If the air filter becomes clogged by dust or the like, internal temperatures will rise and could cause fire, burn
and/or projector malfunction. When the indicators or a message prompts you to clean the air filter, make sure
to clean it as soon as possible. Check and clean the air filter periodically, even if no message is displayed.
Please replace the air filter when it is damaged or too dirty to be cleaned. Replace the air filter when the
lamp is replaced. An air filter of the specified type will be included with replacement lamps for this projector.
