4.3.3 Liquid Cooling Air Filter

CHECK: Monthly
Located on the left/front side of the projector there is an air filter related to the liquid cooling system. Inspect
the filter routinely and replace if it appears greyish in color. Refer to
10 for instructions.

4.3.4 Liquid Cooler

CHECK: Every 6 months
The liquid cooler system circulates liquid to and from the DMD heatsinks in the CP2220 reducing the DMD
operating temperature to an acceptable level. Check the coolant level every 6 months, by removing the top
projector lid. Make sure the level of coolant remains above the minimum level indicator. If the liquid cooling
system should fail, an over-temperature alarm window will display. If an over-temperature state remains for
more than one minute, the lamp will turn OFF.

Filling the Coolant Reservoir

DANGER
Use caution when handling. Do not ingest.
WARNING
unapproved coolant can result in projector damage and will also void projector warranty.
Top up the coolant with the Christie approved coolant Jeffcool E105. Use the refill bottle (with the nozzle)
provided in the Liquid Coolant Fill Service Kit (#003-001837-xx).
When refilling, use caution not to spill or let any of the coolant drip on or near the electronics. Do not allow the
level of coolant to fall below the Minimum Fill Line. NOTE: After filling the reservoir, check the coolant hoses
for kinks which may restrict fluid flow.
TIP: In the event coolant drips on any electronics or other nearby components, blot the affected area using a
dust-free optical grade tissue. It is recommended you blot a few times, discard the tissue and use a new tissue
to blot the area again. Keep repeating this cycle until the coolant is cleaned up. Then lightly moisten a new
tissue with de-ionized water and blot the area again. Use a dry tissue to dry the area off. Repeatedly using clean
tissue and blotting the area should successfully remove coolant spills.

4.3.5 Exhaust Duct and Lamp Fan Interlocks

CHECK: Every 6 months
Check and maintain the projector's two vane switches every 6 months. One is located in the exhaust duct and
the other is near the lamp blower. Check operation as follows:
1. Turn power to the projector ON, but do not turn lamp on.
2. Turn OFF extractor fan.
3. Confirm that the extractor vane switch has indicated an extractor status light error on the TPC Status page.
Turn extractor fan back on.
4. Block the air intake at the rear of the projector.
5. Confirm that the lamp blower vane switch has indicated a "blower error". Clear the air intake to correct the
issue.
