Liquid Cooler; Exhaust Duct And Lamp Fan Interlocks - Christie CP2000-XB Setup Manual

3.2.3 Liquid Cooler

The liquid cooler system circulates liquid to and from the DMDs in the CP2000-XB projection head, keeping
their operating temperature at an acceptable level. Periodically check the coolant level visible by removing the
igniter grille (rear side grille adjacent to the side input panel)—check for 1) leaks and 2) proper liquid level.
NOTE: A failure of the liquid cooling system will trigger an over-temperature alarm condition, clearly
indicated with status displays/lights at the rear of the projector.
FILLING THE COOLER: The cooler should require filling only upon projector installation. Fill with
Christie approved coolant Jeffcool E105 provided in the liquid coolant fill service kit (P/N 003-001837-02).
Danger! HAZARDOUS SUBSTANCE - The coolant used in this product contains ethylene glycol. Use caution
when handling. Do not ingest. Top up as necessary, making sure not to over fill. Coolant does not need to be
drained for transit.

3.2.4 Exhaust Duct and Lamp Fan Interlocks

After installation, check/maintain operation of both vane switches—one in the exhaust duct and one near the
lamp fan—as follows:
1. Turn projector ON (lamp is not needed).
2. Turn your extractor fan OFF.
3. Confirm in LCD status display shows that the extractor fan vane switch has failed. Turn fan back ON to
correct.
4. Block air intake at rear corner (input side) of projection head.
5. Confirm in LCD status display shows that the lamp fan vane switch has failed. Clear air intake to correct.
6. Repeat all steps every 6 months in permanent installations.
7. Maintain vane switches as described in
NOTE: If the exhaust duct becomes significantly blocked—or if a fan fails—the projector's airflow sensor
should trigger a shutdown before the projector becomes overheated or unsafe. Regardless, check the airflow
periodically.
