WARNING  ►Do not replace the filter cover and/or air filter 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 cooled adequately.

When the projector is installed bottom up, please use the accessory filter cover for 
bottom-up use. It is higher than usual filter 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 filter cover and the air filter. Hold the knobs while pulling out it.
