Can I access the lamp and air filter with the ceiling mount installed?

• The projector's lamp cover is located on top of the projector, so you can replace the lamp when the projector is mounted to the ceiling (upside-down). The air filter are located on the side of the projector. You can remove the air filter to clean both sides even if the projector is mounted on the ceiling.
