About the fi lter cover for bottom-up use
WARNING ►Do not replace the fi lter cover and/or air fi lter during use or
immediately after use. Handling while the projector is in a high temperature
could cause a burn and/or malfunction to the projector. Before operating, make
sure that the power switch is off, that the power cord is not plugged in, and that
the projector is cool adequately.
When the projector is installed bottom up, please use the accessory fi lter cover
for bottom-up use. It is higher than usual fi lter cover, to keep the space for intake
ventilation. Please change in the following procedure.
1.
Disconnect all the connectors and adapters that were connected to the
projector’s ports. Then slowly turn the projector so that the lens-side is facing
up. Please be careful for a projector not to fall. While the projector is placed
lens-side up, hold the projector.
2.
Remove the fi lter cover and the air fi lter. Hold the knobs while pulling out it.
