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.
Set the air filter.
Set the air filter in the reverse order to step  .
Clean the air filter.
Suck off deposited dust with a vacuum cleaner.
• Be careful not to suck in the air filter itself.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.Attention
• 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.

Be careful when handling a light source lamp. The lamp unit has high internal pressure. If improperly handled,
explosion might result.
A used lamp unit may burst if it is handled violently.
For disposition of used lamps, request an industrial waste disposal contractor.
Do not reset the cumulative time, except when the lamp unit has been replaced with a new unit.
If you continue to use a lamp after the replacement time, the lamp may break.
Philips screwdriver is necessary when replacing a lamp unit.
Take care not to slip your hand when using a screwdriver.
• A lamp unit is an optional part. Contact the dealer.
Replacement lamp unit model No.: ET-LAD55 (single bulb), ET-LAD55W (double bulbs)
Rating: 300W
Long life lamp unit model No.: ET-LAD55L (single bulb), ET-LAD55LW (double bulbs)
Rating: 160W

Timing of lamp unit replacement
The lamp used for the light source has its due life. The life of light source lamp used in the main unit is 1 500
hours1(when lamp output is HIGH and lamp selection is DUAL). However, it may happen that the lamp
becomes dead (will not light) by the time of 1 500 hours1depending on the characteristics of individual lamps
and working conditions (lamps may reduce their life affected by the times of lighting and the intervals between
previous lighting and next lighting). Therefore, it is strongly recommended for the user to keep a spare bulb.
If your lamp unit is not replaced after 1 300 hours
2(with the lamp output set at “HIGH”), power supply will be
turned off automatically at the time of 1 500 hours1, entering a standby state. After 1 500 hours1of initial
lighting, power supply is turned off automatically about 10 minutes later, entering a standby state even if it is
turned on again.
Indication after 1 300 hours2(with the lamp output set at “HIGH”)
When lamp unit used hours have reached 1 300 hours2, lamp monitor
(LAMP1 or LAMP2) light up including standby state.
Further, an on-screen indication will appear for about 30 seconds as
shown in the diagram on the left, recommending replacement of lamp unit.
(The indication on the left diagram will disappear after about 30 seconds or
when either control button on the rear of main unit or remote control button
is operated.)
After the time of 1 500 hours
1, the on-screen indication will not disappear
unless the menu (MENU) button is operated.
REPLACE THE LAMP
1 This time period is 4 000 hours when long life lamp units are used.
2 This time period is 3 800 hours when long life lamp units are used.
