Installation
Before installing this fi lter to the projector, be sure
to unplug the projector from the outlet.

Cleaning
Before cleaning, be sure to turn off the main power switch and unplug the projector from the outlet.
• Clean the fi lter frequently (at least once a month). When dust accumulates on the fi lter at the air inlet, the
temperature inside the projector may rise abnormally high, causing damage to the internal parts and reducing
the lifetime of the panel.
• In case of any abnormality including an abnormal rise of the inside temperature, the projector may automatically
turn off and go into the standby mode where the light source lamp is turned off in order to protect its internal
parts.
