Maintaining Proper Cooling

The CP2000-ZX high-intensity lamp and electronics rely on a variety of cooling components to reduce internal
operating temperatures. Regular checking and maintenance of the entire cooling system is critical to prevent
overheating and sudden projector failure, and helps to ensure reliable operation of all projector components
over time.

3.2.1 Ventilation

Vents and louvers in the projector covers provide ventilation, both for intake and exhaust. Never block or
cover these openings. Do not install the projector near a radiator or heat register, or within an enclosure. To
ensure adequate airflow around the projector, keep a minimum clearance of 19.69" on the left, right and rear
sides of the projector from any walls or other obstruction.

3.2.2 Air Filter

CHECK: Monthly
It is recommended that you replace the air filter (located on the right side of the projector, near the input
connection panel) whenever you replace the lamp, or sooner in dusty or dirty environments. A clogged air
filter reduces air flow, and can lead to overheating and failure of the projector. Check monthly by inspecting its
color through the side vent grille with a flashlight. A grey colored filter should be replaced; a white filter is still
ok. Refer to Section 4.3 Replacing the Lamp
the laminar airflow device (LAD) filter located just beyond the air filter opening using a flashlight. The LAD
filter should be nearly white or light gray in color.

3.2.3 Liquid Cooler

CHECK: Every 6 months
The liquid cooler system circulates liquid to and from the DMD heatsinks in the CP2000-ZX reducing the
DMD operating temperature to an acceptable level. Check the coolant level every 6 months by removing the
air filter door and viewing it through the grille. Shine a flashlight through the grille if necessary. Make sure the
level of coolant remains between the two level indicators (preferably closer to the top indicator). Refer to
Section 4.4 Replacing the Filter
If the liquid cooling system should fail, it will first trigger an over-temperature alarm window, then turn off the
lamp if it remains in an over-temperature state for more than one minute.
Filling the Coolant Reservoir
Top up the coolant level using the Christie approved coolant Jeffcool E105 and refill bottle with nozzle
provided in the Liquid Coolant Fill Service Kit (Christie P/N 003-001837-01). Danger! HAZARDOUS
SUBSTANCE - The coolant used in this product contains ethylene glycol. Use caution when handling. Do not
ingest. Warning! 1) Do not use coolants other than that specified by Christie with your projector. Using
unapproved coolant can result in projector damage and will also void projector warranty. 2) When refilling,
use caution not to spill or let any of the coolant to drip on or near the electronics. Fill the coolant reservoir
only to its maximum fill line (top level indicator). Do not fill it more than this. NOTE: After filling the
reservoir, check the coolant hoses to ensure no kinks have been introduced that may restrict airflow.
