DLP™ Projector
PT-LW321
Notes on projector placement and operation
The projector uses a high-wattage lamp that becomes very hot during operation. Please observe the
following precautions.
1. Never place objects on top of the projector while it is operating.
2. Make sure there is the unobstructed space as shown below or more around the projector’s exhaust
openings. In addition to this space, also ensure that there is a sufficient work space for removing
and installing the lamp, air filter and other parts.
3. Make sure that nothing blocks the projector’s air intake and exhaust openings. Also, install the pro-
jector so that cool or hot air from other air conditioning equipment does not flow directly toward the
projector’s air intake or exhaust openings.
4. Do not install the projector in an enclosed space. If it is necessary to install it in an enclosed
space, add a separate ventilation system. If ventilation is insufficient, hot air will accumulate at the
intake opening. This may cause the projector’s protective circuit to interrupt projector operation.

periods (one hour or less).
