In addition, leave a space of 30 cm (11.8˝) or more at the sides so that the hot air coming out from the air outlet vents does not get drawn in through the air intake vents. • Set up the projector with a space of 40 cm or more at the front so that the air filter can be replaced. • When the projector is to be placed inside a box and used, ensure the structure has a duct or the like to discharge air from the box, leave the clearances shown in Fig. 2, and ensure the temperature during operation remains within the 0 ˃C to 35 ˃C range. 26 - ENGLISH
