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 (19-11/16˝) or more around the projector's exhaust open-
ings. In addition to this space, also ensure that there is a sufficient work space for removing and installing the
lamp, filter and other parts.
3. 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 35°C/95°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.
Direction of Air Intake and Exhaust
200 mm (7-7/8˝) or more 500 mm (7-5/8˝) or more 500 mm (7-5/8˝) or more
Operating the Projector Continuously
1. When the projector is operated continuously 10 hours or more, the lamp replacement cycle decreases.
2. The lamp replacement cycle also decreases when the projector is used for short periods of time (less than one hour)
repeatedly.
Replacing the Filter Unit
The projector is equipped with the Auto Cleaning Filter (ACF) function, which automatically winds the air filter to set a new
filter element in place according to operating conditions. The filter unit replacement cycle is approximately 10,000 hours.
Please purchase the ET-ACF100 filter unit for replacement use.
