4. Adjust the TPC angle for optimal viewing, then tighten the mounting arm lock securely so that
the TPC is held in place at the required location.
Connect external exhaust ducting
Warning! Failure to comply with the following could result in death or serious injury.
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.
Notice. Failure to comply with the following may result in property damage.
*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.
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:
Lamp Type
2.0 kW
3.0 kW
4.5 kW
6.0 kW
*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).
