Attention
•
Leave a clearance of at least 50 cm (19.7˝) so that the ventilation opening on the rear panel will not be blocked.
•
Set up the projector so that air can flow freely around the rear of the projector. 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.
