Connect External Exhaust Ducting - Christie D4K2560 User Manual

Connect External Exhaust Ducting

At minimum, a 10-inch (25.4 cm) long, strong metal duct must be installed at the projector
and installed to an outside venting duct system to prevent glass shards from exiting the duct
in the event of a lamp explosion. Failure to comply could result in death or serious injury.
*600 CFM is required in projection rooms with an ambient temperature above 25°C or
located at an elevation greater than 3000 feet above sea level. Failure to comply may result
in equipment damage.
Connect the existing outside-venting duct to the 8-inch
diameter exhaust port on the top of the projector. Make sure
there are no obstructions or bends in the ducting or air intakes
and the vane switch at the exit duct moves freely.
The pre-installed outside-venting duct should be rigid at the
projector and must also include a heat extractor and blower
that maintains a minimum of 450 CFM* when the projector is
operating at less than or equal to 25°C (77°F) ambient and less
than 3,000 feet (914.4 m), when measured at the projector
exhaust opening.
To determine the projector exhaust CFM value, use an airflow
meter to measure the ft/min at the rigid end of the open
exhaust duct that connects to the projector. Take the
measurement at the very end of the duct without the projector connected.
Use this formula to determine the CFM value for the projector:
*600 CFM is required in projection rooms with ambient temperature above 25°C
(77°F) or elevation (above sea level) greater than 3000 feet (914.4 m).
Add an extractor or a booster if there is insufficient airflow. Do not mount the extractor on the
projector as this may introduce some vibration into the image.
Never disable the vane switch. Attempting to operate the projector with inadequate airflow
can result in dangerous overheating of the projector. Failure to comply may result in
equipment damage.
To prevent the projector from overheating or becoming unsafe, an alarm condition will be
triggered on the TPC if the duct is obstructed or a fan fails. It is recommended to regularly
verify that the exhaust is unobstructed and functioning correctly.
