Position the projector in a horizontal position; other positions can cause heat
Keep a space of 30 cm or more between the sides of the projector.
Do not use the projector in a smoky environment. Smoke residue may build- up on critical parts and damage the projector or its performance.
Consult with your dealer for special installation such as suspending from a ceiling.
