Check Lead Dressing And Hoses; Exhaust Ducting - Christie CP2000 Setup Manual

CHECK LEAD DRESSING AND HOSES

At this point, integral pedestal-to-head cabling and hose connection should be complete. Check all lead
dressing and secure as neatly as possible to prevent extra cable lengths from dangling or touching other
components. Provide proper strain relief, as necessary. Ensure hoses are free of kinks and sharp turns.

2.1.3 EXHAUST DUCTING

Warm exhaust air from the CP2000 must vent to outside of the building.
Connect pre-installed outside-venting ductwork via 8" inside diameter
fireproof ducting material attached to projector's top exit port. Confirm
that 1) there are no obstructions or "kinks" within the ducting, 2) all air
intake areas of the CP2000 are clear and exposed, and 3) the vane switch
at the exit duct is moving freely. The pre-installed outside-venting duct
should be rigid at the projector, and must also include a heat extractor/
blower that maintains at least 600 CFM when measured at the projector
exhaust opening (Table 2.1).

CP2000-i/h/S
CP2000-h/S
CALCULATE CFM in 8" DUCT:
ft/min or ft/sec at the rigid end of the duct that connects to the projector
(measure right at the end). Multiply the reading by the cross-sectional
area of the 8" duct to calculate the cubic feet/min airflow.
The formula is: Measured linear ft/min x 0.34 = CFM
Depending on the lamp, calculations should show 600 CFM (see Table
2.1) airflow in the 8" exhaust duct. Add extractors/boosters as needed
for your site, as the vane switch (Figure 2-18 Vane Switch) will
prevent the projector from operating if the airflow is inadequate. Do
not mount an extractor onto the projector.
NOTE: If the duct becomes significantly blocked or if a fan fails the
projector should trigger an alarm before becoming overheated or unsafe. Check airflow regularly, as
described in
4.2 Maintaining Proper
Never disable a vane switch. Attempting to operate the projector with inadequate
airflow can result in dangerous overheating.
