2. See Figure 2.22.
ADD EXTRACTOR:
Connect the other end of the duct to
the Christie heat extractor/blower,
twisting to secure "flaps" over pins on
the fan. Make sure that the grille end
of the fan faces down. For longer
exhaust runs at your site, add
extractors/boosters as necessary—the
vane switch at the projector's top exit
port will trigger a projector shutdown
if the airflow is inadequate. To
prevent possible transfer of fan
vibration to the image, do not mount
the extractor directly on the
projector—include at least 6" of duct.
IMPORTANT
Do not exceed 6-ft. duct length
without adding additional extractors.
3. To suspend the projector/fan assembly, always use appropriate rigging hardware
and secure to adequate support structures at your site.
The Christie 6-ft. duct-with-fan weighs approximately 22 lb.
The Christie 6-in. duct-with-fan weighs approximately 15 lb.
Use third-party extractors only if the minimum of 600 CFM airflow can be
maintained.

SECURE SAFETY CABLES:
whenever the fan/duct assembly is suspended. These cables prevent components
from falling if your rigging equipment fails. Figure 2.24 shows the safety cable
required between the cooling assembly and projector in any installation, flown or
not. Attach remaining safety cables between the 1) duct and fan, and 2) fan and
supporting structure.
