2.9 Connect External Exhaust Ducting
Connect the existing outside-venting ductwork to the 8 inch
diameter exhaust port on the top of the projector. Confirm that
there are no obstructions or bends in the ducting, all air
intakes are free of obstructions, 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 ambient and less than
3,000 feet, when measured at the projector exhaust opening.
• *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.
• At minimum, a 10” long, strong metal duct must
be installed at the projector to prevent glass
shards from exiting the duct in the event of a lamp
explosion.
2.9.1 Determine the Projector Exhaust CFM Value
Use an airflow meter to measure the ft/min or
ft/sec 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:
Measured linear ft/min x 0.35 = CFM
