Maintenance
Air filter
WARNING ►Before handling the projector, ensure the power switch is off and the power cable is not plugged in. Then, allow the projector to sufficiently cool. Handling while the projector while hot could cause an electric shock, a burn and/or malfunction to the projector.
►Only use the specified air filter. Do not use the projector with the air filter and the filter cover removed. It could result in a fire and/or malfunction to the projector.
►The air filter should be cleaned periodically. If the air filter becomes clogged by dust or the like, internal temperatures rise and could cause a fire, a burn and/or malfunction to the projector.
NOTE • Please replace the air filter when it is damaged or too soiled, and also when you replace the lamp.
•For a suitable indication about the air filter, please reset the filter time only when you have cleaned or replaced the air filter.
•The projector may display the message such as “CHECK THE AIR FLOW” or turn off the projector, to prevent a internal heat level rising.
If the air filter becomes clogged by dust or the like, internal temperatures rise and could cause a fire, a burn and/or malfunction to the projector. When the indicators or a message prompts you to clean the air filter, clean the air filter as soon as possible.
Please check and clean the air filter periodically, even if there is no message. Please replace the air filter when it is damaged or too soiled. Preparation of a new air filter is recommended.
To obtain a new air filter, please contact ViewSonic for the air filter part number.
When you replace the lamp, please replace the air filter. An air filter of specified type will come together with a replacement lamp for this projector.
1. Turn the projector off, and unplug the power cord. Allow the lamp to cool for at
least 45 minutes.
2. When the projector is suspended from the ceiling, apply the vacuum cleaner to
and around the filter cover first, to prevent penetration of dust or the like.
3. While supporting the projector with one hand, use your other hand to pull the filter
cover forward in the direction of the arrow. Remove the air filter.
