7 Maintenance
This section provides information and procedures for performing cinema projector maintenance. You should 
read through this section  in its entirety before performing maintenance activities.  When you perform cinema 
projector maintenance, obey all warnings and precautions.
7.1 Inspect Ventilation
Vents and louvers in the cinema projec tor covers provide ventilation, both for intake and exhaust. Never block 
or cover these openings. Do not install the cinema projector near a radiator, heat register, or within an 
enclosure. To ensure adequate airflow around the ci nema projector, keep a minimum clearance of 50cm 
(19.69”) on the left, right, and rear sides of the cinema projector. 
7.2 Fill the Coolant Reservoir
 HAZARDOUS SUBSTANCE! The coolant us ed in the cinema projector contains
ethylene glycol. Use caution when handling. DO NOT ingest. 
 Only use coolant recommended by Christ ie in your cinema projector. Using 
unapproved coolant can result in cinema proj ector damage and voids the cinema projector 
warranty. 
The liquid cooler system sends and r eceives coolant from the digital micr omirror device (DMD) heat sinks. 
Check the coolant level every 6 months, by removing th e top cinema projector lid. The coolant level should 
always be above the minimum level  indicator. If the liquid cooling system  fails, an over-temperature alarm 
window appears in the Touch Pad Contro ller (TPC). The lamp turns off if the cinema projector enters an over-
temperature state for longer than one minute. 
Top up the coolant with the Christie  approved coolant JEFFCOOL E105. Use  the refill bottle (with the nozzle) 
provided in the Liquid Coolant Fill Service Kit (P/N: 003-0018 37-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 
kinks which may restrict fluid flow. 
If coolant drips on electronics or othe r components, blot the affected area using a dust-free optical grade tissue. 
It is recommended you blot a few times, discard the ti ssue 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 de-ionized water and 
blot the area again. Use a dry tissue to dry the area.

Maintenance
7.3 Inspect the Lamp
 Always disconnect the cinema projector  from AC power and wear authorized 
protective safety gear.
• Check the contact surfaces of  the anode (positive) and the cathode (n egative) connections for cleanliness.
• Clean electrical contact surfaces regularly to preven t contact resistance from scorching connectors. Use an 
approved contact cleaner.
• Verify that all electrical and lamp connections are secure.
7.4 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 and lamp reflector. Do not perform 
maintenance on other optic al components. Check these componen ts 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. 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 Koda k tissues (18LAB020), Opto-Wipes (18LAB022), Kim 
Wipes or equivalent.
• For the lens only - lens cleaning solution such as  Melles Griot Optics Cleaning Fluid 18LAB011 or equiva-
lent
• For the reflector only - Methanol.
• Cotton swabs with wooden stems.
• Lens cleaning cloth or microfiber such as  Melles Griot 18LAB024 or equivalent.
7.4.1 Clean the Lens
A small amount of dust or dirt on the lens has minima l 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 microfib er 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.
