Maintenance

This section provides information and procedures for performing projector maintenance. You should

read through this section in its entirety before performing maintenance activities. When you

perform projector maintenance, obey all warnings and precautions.

Inspect Ventilation

Vents and louvers in the projector covers provide ventilation, both for intake and exhaust. Never

block or cover these openings. Do not install the projector near a radiator, heat register, or within

an enclosure. To make sure there is adequate airflow around the projector, keep a minimum

clearance of 50cm (19.69”) on the left and right sides of the projector.

Check the Coolant Level

The liquid cooling system keeps the digital micromirror device (DMD) heat sinks cool. Check the

coolant level every 6 months, by removing the top projector lid. The coolant level should be above

the minimum level indicator. If the liquid cooling system fails, an over-temperature alarm window

appears in the touch panel controller (TPC). The lamp turns off if the projector enters an over-

temperature state for longer than one minute.

When adding coolant, use the refill bottle with the nozzle provided in the Liquid Coolant Fill Service

Kit (P/N: 003-001837-XX). When refilling, use caution not to spill or let any of the coolant drip on

or near the electronics. After filling the reservoir, check the coolant hoses for bends which may

restrict fluid flow.

If coolant drips on 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 removed. Then lightly

moisten a new tissue with deionized water and blot the area again. Use a dry tissue to dry the area.

HAZARDOUS SUBSTANCE! The coolant used in the projector contains ethylene glycol. Use

caution when handling. DO NOT ingest coolant. Failure to comply results in death or serious

injury.

Use JEFFCOOL E105 coolant only. Using unapproved coolant can damage the projector

damage and void the warranty. Failure to comply could result in death or serious injury.
