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.

7. Push the clips on the top of the service panel down and out to remove the service panel.
8. Loosen the thumbscrew securing the radiator filter door.
9. Pull the filter up and out and then wash the radiator filter with water and a mild detergent or 
clean it with compressed air.
10. When the filter is completely dry, reinstall it and then install the service panel and top lid.
Inspect the Lamp
• Check the contact surfaces of the anode (positive) and the cathode (negative) connections for 
cleanliness.
• Clean electrical contact surfaces every 5000 hours or after two lamp changes to prevent contact 
resistance from scorching connectors. Use an approved contact cleaner.
• Verify that all electrical and lamp connections are secure.
Inspect and Clean Optics
Unnecessary cleaning of optics can increase the risk of degrading delicate coatings and surfaces. If 
you are not a qualified service technician, you can only inspect and clean the lens. Do not perform 
maintenance on other optical components. 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, 
fingerprints or other marks are obvious on the projected image. Never touch an optical surface with 
your bare hands. Always wear latex lab gloves.
These are the recommend tools for removing dust or grease:
• Soft camel-hair brush
• Dust-free blower - filtered dry nitrogen blown through an anti-static nozzle.
• Dust-free lens tissue, such as Melles Griot Kodak tissues (18LAB020), Opto-Wipes (18LAB022), 
Kim Wipes or equivalent.
Always disconnect the projector from AC power and wear authorized protective safety gear. 
Failure to comply results in death or serious injury.

Maintenance
• For the lens only - lens cleaning solution such as Melles Griot Optics Cleaning Fluid 18LAB011 or 
equivalent
• Cotton swabs with wooden stems.
• Lens cleaning cloth or microfiber such as Melles Griot 18LAB024 or equivalent.
Clean 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. 
Remove Dust
1. Brush most of the dust off with a camelhair brush or use a dust-free blower.
2. Fold a microfiber cloth and wipe the remaining dust particles off the lens with the smooth portion 
of the cloth that has no folds or creases. Do not apply pressure with your fingers. Instead, use 
the tension in the folded cloth to remove the dust.
3. If significant dust remains on the lens surface, dampen a clean microfiber cloth with lens cleaning 
solution and wipe gently until clean.
Remove Fingerprints, Smudges, or Oil
1. Brush most of the dust off with a camelhair brush or use a dust-free blower.
2. Wrap a lens tissue around a swab and soak it in lens cleaning solution. The tissue should be 
damp but not dripping.
3. Gently wipe the surface using a figure eight motion. Repeat until the blemish is removed.
Replace the Lamp
• Lamp replacement must be performed by a qualified service technician. Failure to comply 
results in death or serious injury.
• EXPLOSION HAZARD. Wear authorized protective clothing whenever the lamp door is 
open and when handling the lamp. Never twist or bend the quartz lamp body. Use the 
correct wattage lamp supplied by Christie. Failure to comply results in death or serious 
injury.
• Make sure those within the vicinity of the projector are also wearing protective safety 
clothing. Failure to comply results in death or serious injury.
• Never attempt to remove the lamp when it is hot. The lamp is under pressure when hot 
and may explode, causing personal injury, death, or property damage. Allow the lamp to 
cool completely before replacing it. Failure to comply results in death or serious injury.
Improper installation of the lamp can damage the projector. Failure to comply could result in 
death or serious injury.

Maintenance
Inspect the Card Cage Filter
Use only high efficiency Christie approved filters. Never operate the projector without the filter 
installed.
You should check the condition of the card cage air 
filter monthly. Clean or replace the card cage air filter 
sooner if you are operating the projector in a dusty or 
dirty environment. The filter is located on the left 
side of the projector behind the air filter cover. 
1. Loosen the 2 captive screws on the bottom of 
the filter cover.
2. Pull the cover out and down.
3. Slide the air filter out and inspect it. 
4. If the filter appears dirty and you cannot see 
through it, replace it with a new paper filter, or 
clean it if it is a washable filter. See Cleaning a 
Washable Filter on page 82.
If the filter appears clean, continue to step 4.
5. Replace the air filter with the airflow indicator facing toward the projector. 
6. Install the air filter cover by inserting the 2 bottom tabs and then pushing the cover closed. 
7. Tighten the 2 captive screws.
Cleaning a Washable Filter
If the amount of dirt on the filter is minimal, use a vacuum or compressed air to remove it. If you use 
compressed air, the air must move through the filter in the opposite direction of the air flow indicator 
on the side of the filter.
1. Hold the filter on an angle under warm running water so the water flows through the filter in the 
opposite direction of the air flow indicator on the side of the filter.
2. Rinse the filter thoroughly.
3. Submerge the filter for a minimum of 30 minutes in a container of warm water and two 
tablespoons of mild detergent or liquid dish soap.
If the filter is extremely dirty, move the filter from side to side occasionally, or remove the excess 
dirt by brushing both sides of the filter with a soft brush.
4. Rinse the filter thoroughly by holding it on an angle under cool running water. The air flow arrow 
on the side of the filter should face down.
The installation of a filter that has not been allowed to dry completely can cause an electrical 
short and damage the projector.
