Openings in the cabinet are provided for ventilation. 

To ensure reliable operation of the product and to 

protect it from overheating, these openings must not 

be blocked or covered. 

 

Hot air is exhausted from the exhaust vent. When 

using or installing the projector, the following 

precautions should be taken. 

– Do not put any flammable object or spray can near 

the projector, hot air is exhausted from the air 

vents.

– Keep the exhaust vent at least 3’ (1 m) away from 

any objects.

– Do not touch peripheral parts of the exhaust vent, 

especially screws and metallic parts. These areas 

will become hot while the projector is being used.

– Do not put anything on the cabinet. Objects put on 

the cabinet will not only get damaged but also may 

cause fire hazard by heat.

Cooling fans are provided to cool down the projector. 

The fans’ running speed is changed according to the 

temperature inside the projector.

Exhaust Vent
(Hot air exhaust)

Air Intake Vent

Air flow

The projector uses a lamp which generates significant 

heat. The cooling fans and air vents are provided to 

dissipate the heat by drawing air into the housing and 

the filter is located in the intake vents to prevent dust 

from getting inside of the projector.

In order to care for the projector appropriately, regular 

cleaning is required. Remove any dirt or dust that has 

accumulated on the projector and on or in the filter.

If the projector detects that the filter is clogged, a 

“Filter warning” icon (red) will appear on the screen 

and “WARNING FILTER” indicator on the top panel 

will blink (see below). Stop using the projector 

immediately and clean or replace the filter.

Blocking the air vents and leaving the projector 

uncleaned for a long time may not only damage the 

projector and may require costly repairs but may also 

cause accidents or fire.

For maintenance of the filter, refer to “Filter counter” 

on page 57 and “Maintenance and Filter Cleaning” on 

page 58.
