Section 2: Service Guidelines
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.
2.5.6 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.
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.
