Projector Christie Roadie 25k User Manual

							 INSTALLATION AND SETUP 
 
Roadie 25K User’s Manual 2-15 
For most installations, you will likely have to safely lift or hoist this projector—or a 
stack of 2 projectors—into place. Keep in mind the following critical safety 
guidelines for all handling of the projector. 
 Carrying/Moving the Projection Head 
Four or more people can lift and hand-carry one projection head (with or without a 
FredFrame
) a short distance as required. Never attempt to carry a stack by hand. To 
use equipment to move the projection head, always install a FredFrame
 first. 
 Using a Fork Lift 
 WARNING  
Do not attempt to use a fork lift without first installing the 
fork lift rails on the bottom of the FredFrame
, otherwise 
the base of the projector may crush and damage internal 
components. 
Strong extruded rails that mount to the bottom of the FredFrame accommodate 
forks from a fork lift, and are mandatory for this method of transport. Do not lift the 
projection head with equipment unless the FredFrame
 and forklift rails are 
installed. 
 Using the FredFrame 
To hoist, stack and/or “fly” projectors, you must properly secure each projection head 
within a FredFrame
 and use appropriate rigging and safety cables to raise and/or 
suspend this assembly. If desired, the lamp ballast can also be hoisted and flown from 
its integral rigging bars. Follow the instructions provided with the FredFrame kit. 
 WARNINGS  
Use straps and/or cabling with load capacity adequate 
for the total projection head and frame weight. 
 Remove the lens before hoisting. 
NOTE: Never exceed the Load Rating specified in the FredFrame Stacking & 
Rigging Kit instructions. Critical safety. 
Refer to the complete instructions for using the FredFrame
. These include all 
installation instructions as well as mechanical adjustment procedures for proper 
image alignment. 
 Stacking 
To stack two projection heads together, you must first secure each head within a 
FredFrame
, then secure all corners of the frames together using 4 stacking pins 
(provided). You must also use the Roadie 25K Exhaust Adapter to route exhaust air 
from the bottom projector away from the top projector (not required with a side-by-
side projector row). Do not stack more than 2 projection heads together, and do not 
attempt to move stacked projectors without proper transport equipment.

Roadie 25K User’s Manual 
Before or after you have positioned the projector in its permanent or temporary 
location, install the remaining components: the lens, lamp and external extractor fan. 
 
Primary Lens 
1. Orient your 
primary lens 
with its 
UP 
label at the top 
(see right). 
Fully insert it 
straight into 
the lens mount 
opening all 
the way back 
without 
turning.  
With the lens 
fully back, it 
will seat 
properly 
within the lens 
mount. 
2.  Lock the lens 
assembly in 
place with 
lens clamp 
DOWN. 
3. Secure lens 
safety ring, 
and tether to 
projector (not 
required if 
projector is 
floor-
mounted). 
NOTES: 1) The 
lens seals the 
projection head, 
preventing 
contaminants 
from entering the 
area of main 
electronics. 
Never attempt to 
operate the 
projector without 
a lens installed.

install a lens plug. 2) Always re-install a lens in its previous “UP” orientation, 
otherwise boresight may require re-adjustment. 
Lens Stabilizer 
Install the lens stabilizer at the lens mount as described in 
the Lens Mount Anti-Vibration Upgrade
 instructions 
provided with the projector. This small bracket will help 
stabilize the lens within the mount to minimize vibration in 
projected images. It is packaged with other accessories such 
as the remote keypad, Roadie 25K User’s Manual
, etc. 
Anamorphic Lens Installation 
(OPTIONAL) 
NOTE: The optional anamorphic lens mount is required for use of the 1.25x 
anamorphic lens, producing 2.39:1“scope” images. 
If the anamorphic lens will be used, it is recommended that you add the lens—and its 
mount—before final leveling, boresight adjustment and the like. Install only for those 
installations requiring full-size 2.39:1 “scope” display (mostly side-masking screens) 
obtained by optically stretching a pre-squeezed image. 
1. 
INSTALL THE ANAMORPHIC LENS MOUNT ON THE PROJECTOR: At the front 
of the projector, install the anamorphic lens mount hardware as described in 
the instructions provided with Christie’s Anamorphic Lens Mount Kit. 
2. 
INSTALL THE 1:25x ANAMORPHIC LENS: Clamp the 1.25x anamorphic lens 
mount in place, following the instructions provided with the anamorphic lens 
mount kit. 
 WARNING  
Protective gear required. 
Qualified service technician required. 
Remove the lamp door and open the empty lamp cooling compartment.

Roadie 25K User’s Manual 
 
1. Check lamp cradle (anode end) location for your lamp 
 For 4.5 or 6.0 kW lamps, the 
lamp cradle must be as far 
forward as possible (factory 
default). 
 For 2.0 or 3.0 kW lamps, move 
the cradle to the rear position, i.e., 
approximately 1” closer to the 
reflector. 
2. Install Lamp 
See 6.4, Replacing the Lamp & 
Filter, Steps 7-11. Observe all 
warnings, and wear protective 
clothing and shielding. 
Don’t forget to properly mark the 
“Lamp Installed” label on the lamp 
door to indicate current lamp size. 
 
 
Extractor Fan and Duct 
For any Roadie 25K with any lamp, install the Christie extractor fan and duct to pull 
warm exhaust air from the projector at a minimum rate of 600 CFM. Use either the 6-
in. or the 6-ft. duct in one of the configurations shown below:

							 INSTALLATION AND SETUP 
 
Roadie 25K User’s Manual 2-19 
Direct exhaust as necessary to keep ambient air temperature within operating spec 
(see Section 6, Specifications). If the projector is used for extended periods, 
particularly in a confined space, routing to the outside of the building may be 
required. In all cases, maintain at least 600 CFM at the projector’s top exit port: 
Table 2.3. Airflow Requirements 
Lamp (kW) Minimum Exhaust Airflow Rate 
2.0 600 ft3/min. 
3.0 600 ft3/min. 
4.5 600 ft3/min. 
6.0 600 ft3/min. 
 
INSTALLATION: Follow the installation guidelines provided below, securing all 
components in the order that best suits your site and installation requirements. 
 WARNING  
Do not operate the projector without the Christie 
Extractor components installed. 
1. INSTALL DUCT ON PROJECTOR: See 
Figure 2.23 below. Align either the 6-
inch or 6-foot duct at the projector’s 
top exit port, twisting to secure “flaps” 
over projector pins. Confirm that 1) 
there are no obstructions or “kinks” 
within the ducting, 2) all air intake 
areas of the projector are clear and 
exposed, and 3) the vane switch at the 
exit duct moves freely.

Roadie 25K User’s Manual 
2. ADD EXTRACTOR: See Figure 2.22. 
Connect the other end of the duct to 
the Christie heat extractor/blower, 
twisting to secure “flaps” over pins on 
the fan. Make sure that the grille
 end 
of the fan faces down
. For longer 
exhaust runs at your site, add 
extractors/boosters as necessary—the 
vane switch at the projector’s top exit 
port will trigger a projector shutdown 
if the airflow is inadequate. To 
prevent possible transfer of fan 
vibration to the image, do not mount 
the extractor directly on the 
projector—include at least 6” of duct. 
 IMPORTANT  
Do not exceed 6-ft. duct length 
without adding additional extractors. 
 
 
 
3.  To suspend the projector/fan assembly, always use appropriate rigging hardware 
and secure to adequate support structures at your site. 
The Christie 6-ft. duct-with-fan weighs approximately 22 lb. 
The Christie 6-in. duct-with-fan weighs approximately 15 lb. 
Use third-party extractors only if the minimum of 600 CFM airflow can be 
maintained. 
4. 
SECURE SAFETY CABLES: Three safety cables are provided, and are all mandatory 
whenever the fan/duct assembly is suspended. These cables prevent components 
from falling if your rigging equipment fails. Figure 2.24 shows the safety cable 
required between the cooling assembly and projector in any installation, flown or 
not. Attach remaining safety cables between the 1) duct and fan, and 2) fan and 
supporting structure.

5. CONNECT TO POWER: Connect the line cord of the extractor fan to the “Extractor 
Fan” outlet on the rear panel of the projector. Use appropriate extension cords if 
necessary. The fan will power-up with the projection head, and will run for a 10 
minute cool-down period after the projection head is powered off.

Roadie 25K User’s Manual 
CALCULATE CFM in 8” DUCT: Use an air flow meter to measure the ft/min or ft/sec 
where the duct connects to the projector (measure at 
this end only). Then multiply the reading by the cross-
sectional area of the 8” duct (0.34) to calculate the 
cubic feet/min airflow. The formula is: 
Measured linear ft/min x 0.34 = CFM 
NOTE: If the duct becomes significantly blocked—or if 
a fan fails—the projector should trigger an error 
message before becoming overheated or unsafe. 
Regardless, check airflow regularly
. 
 WARNING  
Never disable a vane switch. Attempting to operate the 
projector without monitoring airflow can result in 
dangerous overheating of the projector. 
Side-Venting Duct (Adapter) 
All stacks require a special side-venting duct adapter between projectors, otherwise 
the top projector blocks exhaust from the top of the bottom projector. This Roadie 
25K Exhaust Adapter Kit is required on any bottom projector in an upright stack of 
two. 
Liquid Cooling 
During operation, a closed loop of flexible tubing circulates liquid coolant from a 
small reservoir to critical electronic components located near the front of the 
projection head. The coolant (a 50/50 mix of distilled water and ethylene glycol) 
should fill slightly more than half of the reservoir to ensure adequate circulation. The 
reservoir, which is located in the igniter compartment, is factory-filled and does not 
require draining for transit. Check regularly. 
 
Sources connect to the Input Panel located on side of the projector closest to the lens. 
See Figure 2.25. 
The upper left corner (
INPUT 1) typically accepts an RGB signal from an external 
analog RGB source, or it can also be used for YPbPr signals. Just beneath these 
BNCs, the DVI-I connector (
INPUT 2) accepts digital or analog display signals from a 
computer. Connect analog composite video at 
INPUT 3 or S-video at INPUT 4 from 
devices such as VCRs, laser disk players or DVD players. At 
INPUT 5, connect serial 
digital YCbCr (4:2:2) or compatible SMPTE signals (note this module can be moved 
to 
INPUT 6  if desired). 
There are also several optional interfaces available for connecting other sources—
these interfaces slide into the remaining unused option slot, and can be removed or 
installed while the projector is running.

INPUT 1 consists of 5 BNCs 
(connectors) for linking to a variety of 
sources. The typical connection would 
be to an RGB source such as a PC, 
Mac, DEC, Sun, SGI and others. This 
projector supports multiple sync types 
with RGB signals: sync-on-green, 
composite sync, and separate H & V 
syncs. 
NOTE: Depending on your source, 
you may need a custom adapter cable 
with BNC connectors at the projector 
end and a different type of connector 
at the other (such as a 15-pin D 
connector for some computer 
sources). Contact your dealer for 
details. 
Connect the 
SYNC BNC input(s). Then 
connect the red, green and blue source 
outputs to the 
RED, GREEN, and BLUE 
BNCs on the 
INPUT 1 panel. If the 
source uses sync-on-green, only the 
red, green, and blue connections are 
required. If the source provides a 
composite sync output, connect it to 
the 
SYNC input labeled HOR/COMP. If 
the source provides separate horizontal 
and vertical sync outputs, connect 
horizontal sync to the 
SYNC input 
labeled 
HOR/COMP and connect 
vertical sync to 
SYNC input labeled VERT. See Figure 2.26.  
NOTES: 1) If for some reason the projector fails to recognize a signal as an RGB 
signal, specify this Color Space option within the Image Settings menu. See 3.7, 
Adjusting the Image. 2) To connect YPbPr signals–such as from DVDs or analog HDTV 
sources–to 
INPUT 1, use the red, green and blue BNCs as described in YPbPr Signals 
(below). 3) This input does not route to the decoder and cannot be used for Composite 
Video or S-Video.
