Cleaning and replacement of air filter
If too much dust accumulates on the air filter, [CLEAN THE AIR FILTER]* appears at the lower left of the screen,
and the temperature monitor (TEMP) will blink once. If even more dust is allowed to accumulate, the temperature
inside the main unit will rise, the temperature monitor (TEMP) will blink twice, and the power is turned off.
Clean the air filter section once every 100 hours or so as a guideline depending on the location of projector
operation.
* It appears only for 30 seconds within 3 minutes after the power is turned on. It disappears if any of the buttons on
the rear side of the main unit or on the remote control is pressed.
Procedure of cleaning
Turn off the main power and remove the power plug from the receptacle.
Turn off the main power supply observing the procedure (Powering off the projector) 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.
• Do not to suck in the air filter itself.
• Do not rinse off the air filter with water.  Doing so will impair the filter’s ability to provide
protection from dust.Attention
• Fit the air filters into place with the filter material 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 absolutely sure to use the air filter specifically designed for use with the projector.Note

Replacing the lamp unit
Precautions on lamp unit replacement
Remove the power plug and confirm that the surroundings of the lamp unit have cooled off.
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.
If you continue to use a lamp after the replacement time, the lamp may break.
Phillips screwdriver is necessary when replacing a lamp unit.
Take care not to slip your hand when using a screwdriver.
WARNING!
When replacing the lamp, allow it to cool for at least one hour before handling it.
• The lamp cover gets very hot, and touching it can cause burns.
Make sure that two lamp units are always installed.
• It is not possible to turn on the power unless two lamp units are installed.
• A lamp unit is an optional part. Contact the dealer.
Replacement lamp unit model No.: ET-LAD40 (single bulb), ET-LAD40W (double bulbs)
• Other lamps than specified above cannot be used. Be sure to use the specified lamp.Note
When to replace the Lamp unit
The lamp units are consumable parts. The lamp brightness decreases gradually as the cumulative operating
time increases, so periodic replacement is necessary. The replacement guideline is 3 000 hours, although the
lamp may become dead (will not light) before 3 000 hours is reached depending on the characteristics of
individual lamps and other factors such as the operating conditions and the installation environment. Therefore,
it is recommended for the user to keep a spare lamp unit.
The risk of the lamp bursting increases after 3 000 hours of operation, so the lamp unit turns off automatically.
After 
2 800 hoursThe indication appears for 30
seconds or until any control button
is pressed.On-screen indication
After 
3 000 hoursThe indication will not disappear
unless a control button is pressed.The lamp monitor lights up red
even in standby mode.

Lamp unit replacement steps
Turn the power off by following the steps on page 23, remove the power plug and
confirm that the surroundings of the lamp unit have cooled off.
Check that the fan has stopped running.
Have a Phillips screwdriver ready ahead of time.
Remove the screw securing the lamp unit
cover, and then slide the lamp unit cover
a little toward the left, and remove it.
Remove the two screws securing the
fan unit.
Lamp unit cover
Open the fan unit as shown in the
figure.
Remove the screws securing the lamp
units (two for each unit), take hold of
the handles, and remove the lamp units.
Install the new lamp unit.
Use a Phillips screwdriver to securely
tighten the 2 lamp unit fixing screws
(two for each unit).

Handle
Lamp unit 1 Lamp unit
Fixing screws
Secure the two screws for securing the
fan unit tightly.
Slide the cover a little toward the right,
and secure it using the screw for
securing the lamp unit cover tightly.
• Firmly install the lamp unit and lamp
unit cover. If not installed firmly, a
protection circuit will function and the
power will not be turned on.Attention
• The lamp units are constructed so that
the screws in step  do not fall
through completely.Note
Caution
The lamp unit will be hot after it has
been used.
You might get burned if you touch it while it is
still hot.

Ceiling Mount Bracket Safeguards
The projector and the ceiling mount bracket are designed sufficiently safety though, make sure the safety cable
provided with the projector is installed and attached to the bottom of the projector when mounting in the ceiling for
safety and security.
Installation work of the ceiling mount bracket should only be carried by a qualified technician according to the
following procedure.
• Even if it is guarantee period, the manufacturer is not responsible for any hazard or damage caused by using a
ceiling mount bracket which is not purchased from an authorized distributors, or environmental conditions.
• Make sure to use a torque driver and do not use an electrical screwdriver or an impact screwdriver.
• An unused ceiling mount bracket should be removed promptly by qualified technician. The followings are included with the other accessories.

Install the ceiling mount bracket
according to the Installation
Instructions.
Attach anchor nuts or curl plugs
available in the market (M8 or 5/16) to a
strong ceiling surface in positions (left
figure) so that there is no slack in the
wire cable provided with the projector.
Pass the loop of wire rope through
anchoring area and tighten the hex
head bolts.
Attach the metal fittings at the ends of
the cable to the locking holes in the
projector main unit using the provided
wire fastening M6 screws, and tighten
the screws firmly to secure the
projector.

• Leave a clearance of at least 50 cm (19.7) so that the ventilation opening on the rear panel will
not be blocked.
• Be careful not to retain exhausted air on the back side of the main unit. Also take steps to ensure
that the hot air blown out from the air exhaust outlet will not be sucked into the air intake.
• Install with clearances of at least 30 cm (11.8) provided for the side panels to enable the air filter
to be removed and re-installed.
• When operating the projector in an enclosure, ensure that the temperature of the surrounding air
within the enclosure remains within the range 0 °C to 40 °C while the projector is running. Also
ensure that the air intake and exhaust vents are unobstructed. Even when the surrounding air
temperature is maintained below 40 °C, operation of the protection circuit could cause a shutdown
due to hot exhaust air being trapped inside the projector. When designing the enclosure, please
give due consideration to the thermal environment surrounding the projector (Figure 2).Attention
