Cleaning and replacement of air filter

If too much dust is deposited in the air filter, temperature inside the main unit will rise and the temperature monitor (TEMP) lamp blinks, eventually turning off the power supply.

Clean the air filter section once every 100 hours or so as a guideline depending on the location of projector operation.

Procedure of cleaning

Turn off the main power and remove the power plug from the receptacle.

Turn off the power supply observing the procedure (How to turn “OFF” the power supply) on page 40 and then remove the power plug.

Dismantle the air filter.

Put a hand in the bottom of the air filter,

take out the filter from the main unit while pulling toward yourself.

Clean the air filter.

Suck off deposited dust with a vacuum cleaner.

Attention • Be careful not to suck in the air filter itself.

Air filter

Mount the air filter.

Set the air filter and then mount the filter in the reverse order to step .

Attention • The air filter must be fitted in place when using the projector.

Using the projector without the air filter fitted inside, dirt and dust are sucked into the projector, causing failure.

Note • If cleaning cannot remove the dust completely, then it is a sign to replace the air filter. Consult the dealer. In addition, when the lamp unit is replaced, also replace the air filter.
