SPECFILE DLP™Projector 12/12 PT-LW271 As of August 2013 SFD13M011-1 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 enc\ losed 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. Direction of air intake and exhaust 500 mm (19-11/16) or more 500 mm (19-11/16) or more 1000 mm (39-3/8) or more Intake Exhaust Operating the projector continuously 1. If the projector is to be operated continuously 22 hours or more, lamp replacement cycle duration becomes shorter. 2. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short periods (one hour or less). Weights and dimensions shown are approximate.
