Liquid Cooler; Exhaust Duct & Lamp Fan Interlocks - Christie CP2000-SB Setup Manual

2.2.3 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 3-33 Check Hose for Airlock Problem, on page 3-20. NOTE:
Refer to the CP2000-SB User Manual (020-100162-xx) for all cooler operating details.
2.2.4 Exhaust Duct & Lamp Fan Interlocks
Check/maintain both vane switches-one in the exhaust duct and one near the lamp fan-at least every 6 months.
Check operation as follows:
1. Turn projector ON (lamp is not needed).
2. Turn extractor fan OFF.
3. Confirm that the TPC displays an alarm window indicating that the extractor fan vane switch has failed.
Turn fan back on to correct.
4. Block air intake at rear corner of projector head on the operator's side.
5. Confirm that the TPC displays an alarm window indicating that the lamp fan vane switch has failed. Clear
air intake to correct.
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.
