Cool the Lamp Completely

Lamp may explode causing bodily harm or death. Always wear protective clothing
whenever lamp door is open or while handling lamp. Ensure those within the vicinity of the
projector are also suited with protective clothing. Never attempt to access the lamp while the
lamp is on. Wait at least 10 minutes after the lamp turns OFF before powering down,
disconnecting from AC and opening the lamp door.
The lamp operates at a high pressure that increases with temperature. Failure to allow the lamp to sufficiently
cool prior to handling increases the potential for an explosion causing personal injury and/or property damage.
After turning the lamp OFF, it is crucial that you wait at least 10 minutes before disconnecting AC and
opening the lamp door. This provides enough time for the cooling fans to properly cool the lamp. Ensure the
lamp is completely cooled before handling and always wear protective clothing!

Cooling

The CP4230 high-intensity lamp and electronics rely on a variety of cooling components to reduce internal
operating temperatures. Regular inspection and maintenance of the entire cooling system is critical to prevent
overheating and sudden projector failure and helps to ensure reliable operation of all projector components
over time.

2.7.1 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 ensure
adequate airflow around the projector, keep a minimum clearance of 0.5m (19.69") on the left, right and rear
sides of the projector from any walls or other obstructions.

2.7.2 Light Engine Air Filter

Check: Monthly
It is recommended the air filter (located on the right side of the projector near the input connection panel) is
replaced whenever the lamp is replaced, or sooner in dusty or dirty environments. A clogged air filter reduces
air flow and can lead to overheating and failure of the projector. Check monthly by inspecting its color through
the side vent grille with a flashlight. A grey colored filter should be replaced. Refer to
Filter, on page 5-12

2.7.3 Liquid Cooling (Radiator) Air Filter

Check: Monthly
Located on the left/front side of the projector the air filter for the liquid cooling system, should be inspected
routinely and replaced if it appears greyish in color. Refer to
instructions.
