INSTALLATION & SETUP
Figure 2.26. Safety Cable at Projector—Flown or Front Mount
Connect the line cord of the extractor fan to the "Extractor
CONNECT TO POWER:
Fan" outlet on the rear panel of the projector. Use appropriate extension cords if
necessary. The fan will power-up with the projection head, and will run for a 10-
minute cool-down period after the projection head is powered off. This ensures
proper lamp cooling.
Use an air flow meter
CALCULATE CFM in 8" DUCT:
to measure the ft/min or ft/sec where the duct
connects to the projector (measure at this end
only). Then multiply the reading by the cross-
sectional area of the 8" duct (0.34) to calculate the
cubic feet/min airflow. The formula is:

Measured linear ft/min x 0.34 = CFM
NOTE: If the duct becomes significantly blocked – or if a fan fails – the projector
should trigger an error message before becoming overheated or unsafe. Regardless,
check airflow regularly.
