Maintenance 65
Replacing the filter
In order to prolong the lifetime of your projector and ensure smooth air circulation
for efficient light source cooling, it is important to replace the dust filter periodically.
We recommend replacing the filter every 500 hours to keep the best dust-proof
ability.
• Be sure to turn off the projector and unplug it from power source
before replacing the filter.
• If your projector is suspended upside-down or is not easily accessible,
pay special attention to your personal safety when replacing the dust
filter.
1.
Have the following items ready:
•
A suitable cross-head (phillips type)
screwdriver.
•
Spare dust filter (available from your dealer).
2.
Locate the dust filter cover on the side of the
projector and loosen the four screws using
the screwdriver. Keep the screws in a safe
place for later use.
3.
Detach the dust filter cover from the
projector.
4.
Replace the old (used) filter
in the dust
filter cover with the spare (new) filter
.
Dispose of the old filter properly according
to your local regulations.
