If the exhaust duct becomes significantly blocked — or if a fan
Note
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, check electrical, optical and other
components regularly as described below.
SHOCK HAZARD. Turn off the SC-1 and disconnect it from AC
WARNING
before performing any maintenance or cleaning.
Do the following every 60 days or 500 hours of projector use:
• Check the contact surfaces of the 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 the 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.
When to Check the 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. Always wear protective clothing while inspecting or cleaning.
Note that color on the reflector surface may vary; this is normal.
For cleaning off dust and/or grease, you will need:
• Soft camel-hair brush.
• Dust-free blower — filtered dry nitrogen blown through an anti-static nozzle.
• Dust-free lens tissue: Melles Griot® Kodak tissues (18LAB020), Optowipes™
(18LAB022), Kimwipes® or equivalent.
• Lens cleaning solution: Melles Griot Optics Cleaning Fluid 18LAB011 or equivalent (for
lens only).
• Methanol (for reflector only).
• Cotton swabs with wooden stems only
• Lens cleaning cloth/microfiber: Melles Griot 18LAB024 or equivalent.
