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 end of the duct without the projector
connected.
Use this formula to determine the CFM value for the projector:
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.
Remove the projector shroud
The lens side shroud must be removed to gain access to the lens. The other shroud must be
removed when connecting the AC power cord into the front face of the projector.
1. Use finger pressure to push down on the shroud clips located at the top and bottom of the
shroud as shown by the arrows.
2. Carefully slide the shroud sideways and forward away from the lens mount and lens.

Notice.
Failure to comply with the following may result in property damage.
Never disable the vane switch. Attempting to operate the projector with inadequate airflow
can result in dangerous overheating of the projector.
i
To prevent the projector from overheating or becoming unsafe, an alarm sounds if the duct
is obstructed or a fan fails. Christie recommends regularly verifying that the exhaust is
unobstructed and functioning correctly.
Warning!
Failure to comply with the following could result in death or serious injury.
• Never install the shroud for overhead installations.
