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:

1. Turn projector ON (lamp is not needed).

2. Turn your extractor fan OFF.

3. Confirm that the LCD status display shows that the extractor fan vane switch has

failed. Turn fan back ON to correct.

4. Block air intake at rear corner (input side) of projection head.

5. Confirm that the LCD status display shows that the lamp fan vane switch has

failed. Clear air intake to correct.

6. Repeat all steps every 6 months in permanent installations.

7. Maintain vane switches as described in 6.3, Maintenance and Cleaning.

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.

WARNING

SHOCK HAZARD. Disconnect projection head and ballast

from AC at BOTH

wall breakers.

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

LENS: 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.

LAMP REFLECTOR: Inspect the mirror surface (reflector) for cleanliness only during a

lamp replacement, when the lamp is out. If necessary, clean as described below—
