Using a Phillips screwdriver, secure the lamp door. 
Filter Replacement Procedure 
 Only use Christie approved filters. See Table 5.1.
The filter located at the front side of the projector and should be replaced whenever the lamp is replaced. If you 
are working in an extremely dusty environment you may want to replace the filter sooner. If this filter is not 
replaced, airflow may become restricted and cause the projector to overheat.Use the filter provided in the 
Christie approved Lamp and Filter Kit for your specific projector model. See Table 5.1.
1. TURN OFF THE PROJECTOR, COOL AND UNPLUG
Before removing or installing a filter, turn off the projector and allow it to cool for 5 minutes before 
unplugging.
2. REMOVE FILTER DOOR
Loosen the lock screw at the bottom of the filter door. Lift the door away from the projector. See Figure 5-6.

3. REPLACE FILTER
Remove the old filter and insert the new one. 
NOTE: The direction arrows on the outside edge of the filter. 
Ensure the filter is installed with the arrows pointing into the projector.
4. RE-INSTALL THE FILTER DOOR
Secure the lock screw.
5.2 Replacing the Projection Lens
IMPORTANT! Remove the rear lens cap from the new lens. Keep the front lens cap on the lens to protect it 
during installation.
1. Rotate the lens clamp to the OPEN position, to remove old lens. See Figure 5-7.
FIGURE 5-7 
2. Align the new lens interface plate with the lens mount. Align the lens electrical connector with the mating 
connector on the lens mount. Fully insert the assembly straight into the lens mount opening without 
turning. Press using your hand as shown in Figure 5-8. 
NOTE: Ensure the lens is not inserted at an angle, 
as this can cause damage.

3. While holding the lens flat against the lens mount, rotate the lens clamp clockwise to lock the lens 
assembly in place. See Figure 5-9 .
FIGURE 5-9 
4. Remove the front lens cap.
5. For added stability such as motion applications, fasten the security screws provided with the lens mount. 
See Figure 5-10.
FIGURE 5-10 
6. Use a 5mm hex driver to fasten the red security screws provided with the lens mount (Figure 5-10). 
NOTES: 1) Recommended for heaviest lenses such as 0.73:1 and 1.2:1. 2) The red security screws MUST 
be installed when hoisting the projector overhead, or installing the projector in an overhead position.
 Use of the lens red security screws or the lens retaining screws is required if the 
projector is hoisted or installed in an overhead position.

5.3 Cleaning the Lens
Check periodically. 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 only if absolutely necessary.
Dust:
1. Brush most of the dust from the lens with a camel-hair brush and/or blow dust away with a dust-free 
blower.
2. Fold a microfibre cloth smooth and gently wipe remaining dust particles from the lens. Wipe evenly with 
the smooth portion of the cloth that has no folds or creases. Do not apply pressure with your fingers - use 
the tension in the folded cloth itself to collect dust.
3. If significant dust is still bound to the surface, dampen a clean microfibre cloth with coated optics cleaning 
solution (damp, not dripping). Wipe gently until clean.
Fingerprints, smudges, or oil:
1. Brush most of the dust from the lens with a camel-hair brush and/or blow dust away with a dust-free 
blower.
2. Roll a lens tissue around a swab and soak it in coated optics cleaning solution. Tissue should be damp, but 
not dripping.
3. Gently wipe the surface using a figure-8 motion. Repeat this motion until the blemish is removed.
5.4 Liquid Coolant Maintenance
5.4.1 Liquid Cooler (P/N: 003-100668-XX)
 The coolant used in this product contains ethylene glycol. Use caution when handling. 
DO NOT ingest. DO NOT use coolant other than those specified by Chrisite for your 
projector. Using unapproved coolant can result in projector damage and will void the 
warranty.
Check Liquid Coolant Level
1. Remove the 3 stacking mounts, if installed. Refer to Section 2.2.2 Installation Considerations.
2. Release the 8 quick release screws that secure the top cover.
3. Lift the top cover off and set aside.
4. Locate the Liquid Cooling Module and inspect the liquid level window. 
NOTE: The arrow is next to the 
window which indicates the “MIN FILL LEVEL”. Refer to Figure 5-11.
5. If coolant is below the “MIN FILL LEVEL” add more coolant.

J Series 2.0, 2.4, and 3.0kW User Manual5-9020-100707-01  Rev. 1  (10-2011)
Refilling Liquid Coolant Module
1. Using a flat head screwdriver, remove the fill port cap and the air vent cap. See Figure 5-11.
2. Using a funnel and coolant, fill the liquid cooling module until the coolant is within 2mm of the top cover.
3. Using a flat head screwdriver, replace the fill port cap and the air vent cap.
NOTE: If refilling the liquid coolant module outside of the projector, the level of coolant can be seen by looking 
through the liquid level window.
FIGURE 5-11 
Remove the Liquid Coolant Module from the Projector (Optional)
1. Using a 6mm hex driver or Allen key, remove the 2 bolts securing the top frame bracket. Refer to Figure 5-
12 (LEFT).
2. Disconnect the electrical connector by depressing the lock tab and pulling.
3. Disconnect the liquid connectors from the liquid coolant module by pushing and turning counterclockwise. 
NOTE: The connectors are leak free and will not leak when connecting or disconnecting.
4. Using a 3mm hex driver or Allen key, remove the 4 screws securing the liquid coolant module to the 
projector. Refer to Figure 5-12 (RIGHT).
5. Carefully lift the liquid coolant module out of the projector.
6. Check liquid coolant level as above.
7. If necessary, refill the liquid coolant as above.
8. Replace the liquid coolant module by reversing steps 1-5 above.

5.5 Power Cord and Attachments
 Use only the AC power cord supplied. Do not attempt operation if the AC supply and 
cord are not within the specified voltage and power range. Refer to Section 
7 Specifica-
tions
.
• Only use attachments or accessories recommended by Christie, such as the specific power cord supplied. Use 
of other attachments or accessories with this projector may result in the risk of fire, shock or personal injury.
• Do not allow anything to rest on the power cord. Locate the projector where persons walking on it or objects 
rolling over it cannot abuse the cord.
• Operate the projector at the specific voltage only. Do not overload power outlets and extension cords as this 
can result in fire or shock hazards.
• The projector is equipped with a 3-wire plug having a third (grounding) pin. This is a safety feature. If you 
are unable to insert the plug into the outlet, contact and electrician to have the outlet replaced. Do not defeat 
the safety purpose of the grounding type plug.

5.6 Ventilation
Slots and vents in the projector provide ventilation. Never block or cover these openings. This ensures reliable 
operation of the projector and prevents overheating.
• Do not place the projector over a radiator or heat register. The projector should not be placed in an enclosure 
unless proper ventilation is provided.
• Do not insert objects into the ventilation openings of the projector. They may touch dangerous voltages or 
short out components resulting in a fire or shock hazard. Do not spill liquids of any kind into the projector. 
Should an accidental spill occur, immediately unplug the projector and have it serviced by a qualified service 
technician.
5.7 Replacing Keypad Batteries
The IR remote keypad requires 2 AA size, 1.5V batteries (preferably alkaline).
To install new batteries:
1. Open the battery compartment at the backside of the 
remote by placing your thumb/finger in the oval 
depression and sliding the cover out about 1/2 inch. 
Remote the old batteries and properly discard. Wait a 
minute or two.
2. Place the new batteries in the compartment, orienting 
the positive/negative of each battery according to the 
labels in the compartment. 
3. When the batteries are in place, replace the cover by placing the cover 1/2 inch from its closed position and 
slide it into place. 
NOTE: Do not force the cover closed.
5.8 Servicing Requirements
If any of the following conditions exist, immediately unplug the projector from the power outlet and refer 
service to Christie accredited service personnel.
• The power cord has been damaged
• The internal cooling fans do not come on within two minutes after the projector is first turned on
• Liquid has been spilled into the projector
• The projector has been exposed to excessive moisture
• The projector does not operate normally
