Lamp replacement
This projector is equipped with a lamp to project images. This lamp is
a consumable. It may burn out or its brightness may decrease during
use. In such cases, replace the lamp with a new one as soon as possi-
ble. Be sure to replace the lamp with a new lamp separately sold that
is exclusive to this projector. Contact your dealer for purchase of the
lamp.
Replace the spare lamp using the lamp attachment unit that is
equipped with the spare lamp (separately sold) designed specifically
for this projector.
Caution:
• Do not remove the lamp immediately after using the projector. You
may get burned because the lamp is very hot after use.
• Before replacing the lamp, press the POWER button to turn off the
lamp and wait for two minutes for lamp to cool down. Unplug the
power cord from wall outlet and wait one hour for the lamp to cool
down completely.
• Do not remove the lamp except for replacement. Careless han-
dling can cause injury or fire.
• Do not touch the lamp directly. It may break and cause injury or
burn.
• Be sure not to drop the lamp lid screw into the projector. Also be
sure not to put metal or any flammable objects inside because it
may cause fire or electric shock. If any objects should fall inside,
unplug and contact your dealer.
• Install the lamp securely to prevent failure and fire.
• If the lamp should break, small glass fragments may fall out
through the grilles and some may remain inside of the projector or
the lamp box. When taking the lamp box out, be sure to turn over
the projector and hold the handle of the lamp box to avoid injury
due to the glass fragments.
• If the lamp should break, never shake the lamp box or hold it in
front of your face after removing it. The lass fragments may fall out
and cause injury to your eyes.
• Be sure to use the lamp dedicated to this projector, VLT-XD221LP
for XD221U/XD221U-G. Use of other lamps may cause a failure of
the projector.
• Do not use any other tools for replacing the spare lamp, and be
sure to use the lamp attachment unit that is equipped with the
spare lamp (separately sold) designed specifically for this projec-
tor. Use of other tools may cause a failure of the projector.
Make sure that the projector is securely held in place.
1. Remove the cover (a) of the screw fixing the lamp cover with a fin-
gernail. If it is difficult to remove it with a fingernail, use a fine-
tipped tool such as flathead screwdriver.
2. Remove the screw (b) and slide the lamp cover (c) for removal.
The lamp unit is fixed in position with two retaining claws (d) inside
so the lamp attachment unit (e) designed specifically for this pro-
jector is required to replace the lamp.
Do not pull out the lamp forcibly. The lamp unit may be irretrievably
damaged.
A new lamp unit can be installed without the lamp attachment unit.
3. Loosen the two screws (g) indicated as arrows (
J
) in figure, and
mount the lamp attachment unit (e).
Slide the lamp attachment unit in the direction indicated by a white
arrow after the installation of it, and hook the claw (f) into the hole
of the device to fix the lamp attachment unit.
If not hooking the claw, the lamp attachment unit will be lifted with-
out being fixed in the precise position.
(Caution)
When replacing the lamp, do not remove the screws other than
those in the above picture. If do, it might cause the failure of prod-
uct.
When the projector is mounted to the ceiling:
Secure the lamp attachment unit and the projector with the screw
(h) that come with the lamp attachment unit. Otherwise, the lamp
unit may fall from the inside and cause injuries.
• Contact your dealer when replacing the lamp unit with the pro-
jector mounted to the ceiling.
4. Pull up the handle (i), and then pull out the lamp unit (j) by the han-
dle.
