Air filter cleaning (continued)
Notes
When the air filter is dusty, the ventilation is
impaired. This causes the temperature inside the
projector to rise, and may damage the unit.
Attach the air filter cover firmly after the cleaning.
If it is not set correctly, the dusts will enter and
they will be projected and overlapped on the
picture.
If you wash the air filter with water, be sure to let it
dry fully before reinstalling it. Using it damp will
result in malfunction.
If the air filter is damaged, contact your store of
purchase and replace it with a new one. Using a
damaged air filter will cause dust or dirt to get
inside the projector and onto the images.
Cleaners nozzle
Clean the air filter.
Use a vacuum cleaner to carefully remove any
dust and dirt from the air filter cover, air filter and
filter frame.
Be careful that the air filter is not sucked into the
vacuum cleaner.
