Cleaning and Replacing the Air Filter

Clean the air filter and air intake and exhaust vents on the

bottom and rear of the projector after every 100 hours of use.

If not cleaned periodically, they can become clogged with dust,

preventing proper ventilation. This can cause overheating and

damage the projector. When the filter is clogged, the projector

displays the message

To clean the air filter and air vents, follow these steps:

1. Turn off the projector, allow it to cool down, and unplug the

power cord.

2. Clean the air vent on the back of the projector.

Use a small vacuum cleaner designed for computers and

other office equipment. If you don't have one, use a very soft

brush (such as an artist's brush).

3. Turn the projector upside-down and clean the filter and air

intake vents on the base of the projector.

Air vent

If dirt is difficult to remove or the filter is torn, replace it.

The air filter set (part number V13H134A06) contains two

filters. Contact your dealer or call Epson at (800) 873-7766

to obtain a new set. In Canada, please call (800) 463-7766 to

locate a dealer.

Note:

When you get a replacement lamp for your projector, a new air

filter is included. Replace the filter when you replace the lamp.
