CALCULATE CFM in 8" DUCT:
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.
Never disable a vane switch. Attempting to operate the
projector without monitoring airflow can result in
dangerous overheating of the projector.
Side-Venting Duct (Adapter)
NOTE: Available early 2005.
All stacks require a special side-venting duct adapter between projectors, otherwise
the top projector blocks exhaust from the top of the bottom projector. This Roadie
25K Exhaust Adapter Kit is required on any bottom projector in an upright stack of
two.

Liquid Cooling

During operation, a closed loop of flexible tubing circulates liquid coolant from a
small reservoir to critical electronic components located near the front of the
projection head. The coolant (a 50/50 mix of distilled water and ethylene glycol)
should fill slightly more than half of the reservoir to ensure adequate circulation. The
reservoir, which is located in the igniter compartment, is factory-filled and does not
require draining for transit. Check regularly.
Sources connect to the Input Panel located on side of the projector closest to the lens.

There are also several optional interfaces available for connecting other sources—
these interfaces slide into the remaining unused option slot, and can be removed or
installed while the projector is running.
