Maintaining Proper Cooling

The CP2000-SB 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.

6.2.1 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.

6.2.2 Air Filter

It is recommended that you replace the air filter (located near the lens corner of the projection head) whenever
you replace the lamp-or sooner, in dusty or dirty environments. A clogged filter reduces air flow, and can lead
to overheating and failure of the projector. Check monthly. Refer to
for instructions. It is also recommended that you visually check the laminar airflow device (LAD) just beyond
the filter opening. The LAD should be nearly white or light gray in color.

6.2.3 Liquid Cooler

The liquid cooler system circulates liquid to and from the DMDs in the CP2000-SB projection head, reducing
their operating temperature to an acceptable level. Periodically check the coolant level visible through the
gauge/window on the non-operator's side of the pedestal, and make sure that it remains between the two
notches (preferably closer to the top notch).
If the liquid cooling system should fail, it will trigger an over-temperature alarm window.
FILLING THE COOLER:
The cooler should require filling only upon projector installation (refer to
Connection of Components). 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, watching the gauge
closely.
Important! Whenever coolant has been added or replaced, check for a possible airlock upon the next
projector power-up. Refer back to Figure 2-33 Check Hose for Airlock problem, on page 2-21.
