up as necessary, making sure not to over fill. Coolant does not need to be drained for
transit.
After installation, check/maintain operation of both vane switches—one in the
exhaust duct and one near the lamp fan—as follows:
Turn projector ON (lamp is not needed).
1.
Turn your extractor fan OFF.
2.
Confirm that the LCD status display shows that the extractor fan vane switch has
3.
failed. Turn fan back ON to correct.
Block air intake at rear corner (input side) of projection head.
4.
Confirm that the LCD status display shows that the lamp fan vane switch has
5.
failed. Clear air intake to correct.
Repeat all steps every 6 months in permanent installations.
6.
Maintain vane switches as described in 6.3, Maintenance and Cleaning.
7.
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.
To help ensure optimized performance and reliability, regularly check electrical,
optical and other components as described below.
SHOCK HAZARD. Disconnect projection head and ballast
Do the following every 60 days or 500 hours (always disconnecting from AC first):

Check the contact surfaces of positive (anode) and cathode (negative)
connections for cleanliness. Clean electrical contact surfaces as necessary to
prevent contact resistance from scorching connectors.

Verify that all electrical and lamp connections are tight.
Unnecessary cleaning of optics can be more harmful than helpful, increasing the risk
of degrading delicate coatings and surfaces. In this projector, check only the lens and
lamp reflector—maintenance of other optical components requires a qualified service
technician. Check these components periodically in a clean, dust-free environment
using a high-intensity light source or flashlight. Clean them only when dust, dirt, oil
or other marks are obvious. Never touch an optical surface with your bare hand—
always wear latex lab gloves.
When to Check
A small amount of dust or dirt on the lens has minimal effect on image

quality—to avoid the risk of scratching the lens, clean the lens only if absolutely
required. See below.
Inspect the mirror surface (reflector) for cleanliness only during a
