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) 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 23 and then remove the power plug.
Dismantle the air filter.
There are two air filters, one at the left and one at the right.
Use your finger to pull the air filter tab toward you, and remove it from the main unit.
Clean the air filter.
Suck off deposited dust with a vacuum cleaner.
Air filter
Attention • Be careful not to suck in the air filter itself.
Set the air filter.
Set the air filter in the reverse order to step 
.
Attention • Fit the air filters into place with the filter material (which looks like a sponge) facing the back. (The left and right filters have the same shape.)
•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.
