1)
Wash the air filter unit. (Fig. 1)
i) Soak the air filter unit in cold or warm water and then lightly rinse it.
f Do not use cleaning tools such as brushes.
f
When rinsing, hold the frame of the air filter unit without putting strong pressure on the filter unit.
ii) Rinse the air filter unit two to three times using fresh water each time.
f
Insufficient rinsing may result in odors.
2)
Dry the air filter unit. (Fig. 2)
f
Let the air filter unit naturally dry off in a well-ventilated place where there is little dust and is not exposed to
direct sunlight.

1)
Attach the air filter unit to the projector.
f
The air filter unit has no difference between top and bottom, but is two-sided. Match the protrusion position
of the air filter unit with the grooves on the projector body.
f
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.
f
Confirm that the tabs of the air filter unit compartment of the projector body are hooked to the air filter unit
frame.

Attention
f
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.

f
Do not disassemble the air filter unit.
f
Take care not to touch the air intake fan in the air filter unit compartment when removing dirt or dust.
