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 an unobstructed space of 500 mm or more around the projector’s exhaust
openings.
3. Do not stack projector units directly on top of one another. If two units must be stacked for back-
up use in ordinary projection, use a method as shown below and provide ample space between the
units to ensure that exhaust heat does not accumulate near the intake opening or around the units.
Dual stacked projection of the PT-DW5100/DW5100L is not recommended.
4. If the projector is placed in a box or enclosure, ensure the temperature of the air surrounding the
projector is between 0°C/32°F and 40°C/104°F*. Also make sure the projector’s intake and exhaust
openings are not blocked. Take particular care to ensure that hot air from the exhaust openings is
not sucked into the intake openings.
* Even when the ambient temperature near the intake opening is 40°C/104°F or lower, an accumulation of hot air inside the cabinet may
cause the protective circuit to activate and shut down the projector. Please give ample consideration to the design with regard to
ambient temperature conditions.
Operating the Projector Continuously
1. If the projector is to be operated continuously 24 hours a day, use the dual-lamp optical system’s alter-
nating lamp operation (lamp changer) function. The projector cannot be operated continuously 24 hours
a day in dual-lamp mode.
Allow a minimum of two hours per day of non-operation time.
2. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short
periods.
