ff Hook the air filter unit frame at the air exhaust port side to the two tabs of the back side of the projector’s air filter unit compartment and perform Step 2) in “Removing the air filter unit” in the reverse order to attach.

ff Confirm that the tabs of the air filter unit compartment of the projector body are hooked to the air filter unit frame.

2)Attach the air filter cover to the projector and use a Phillips screwdriver to tighten the air filter cover screw.

ff Perform Step 2) in “Removing the air filter unit” (x page 143) in the reverse order.

Attention

ff After washing the air filter unit, dry it thoroughly before attaching it back to the projector. Attaching a wet unit will cause an electric shock or malfunction.

ff Do not disassemble the air filter unit.

ff Take care not to touch the radiator fin when removing dirt or dust.

Note

ff Make sure that the air filter unit is properly attached before using the projector. If it is not properly attached, the projector will suck in dirt and dust causing a malfunction.

ff If you use the projector without attaching the air filter unit, the filter indicator <FILTER> blinks in red and the message appears on the projected image for approximately 30 seconds.

ff Replace the air filter unit with the new optional Replacement filter unit (Model No.: ET‑EMF510) if it is damaged or if the dirt does not come off even after washing.

ff Air filter replacement is recommended after cleaning the unit two times. ff The dust-proof properties may be reduced after each cleaning.
