2.4 Installation Safety and Warning Guidelines

WARNING

Figure 2-2 Position the cinema projector

QUALIFIED TECHNICIAN REQUIRED for all installations. This product must be

installed in a restricted access location.

Never operate the cinema projector without all of its covers in place.

The cinema projector uses a high-pressure lamp that may explode if improperly handled. Always wear manufacturer approved protective safety clothing (gloves, jacket, face shield) whenever the lamp door is open or when handling the lamp. Only qualified technicians should install cinema projector lamps.

To prevent the cinema projector from tipping unexpectedly, you must install the safety strap on the rear of the cinema projector.

our or more people are required to safely lift and carry one projection head a short distance. Remove the lamp before transporting the cinema projector.

Keep the cinema projector level when you lift or transport it. Avoid tilting the cinema projector to the right. This can introduce an air bubble into the coolant hoses that can result in an air lock and the overheating of the cinema projector.

Section 2: Installation and Setup

Perform a automatic LampLOC™ adjustment when you move, level, or install a new lamp in the cinema projector.

2.5 Position the Cinema Projector and Lamp Power Supply

1. Position the cinema projector at an appropriate throw distance (cinema projector-to-screen distance) and

vertical position. Ideally, center the cinema projector with the theatre screen. If space is limited, aim the cinema projector slightly off-center. This increases side keystoning, but reduces the horizontal lens offset required.

CP4230 Setup Guide 2-5

020-100669-03 Rev. 1 (05-2014)

Section 2: Installation and Setup

Figure 2-3 Side View of Rack Stand

NOTE: Keep the cinema projector lens as parallel to the scr een as poss ible, even if significantly above the

screen center. When a particularly short throw distance combines with a very wide screen, you may have to forfeit some aim and stay more parallel to the screen. In such cases, some lens offset can reduce the keystone distortion.

2. Locate the lamp power supply so that its cables reach the left side of the cinema projector.

3. If you are using an optional rack stand assemble the rack stand using the instructions provided with the rack stand. NOTES: 1) For better access, wire the LPS before installing it into the rack stand. 2) Use the

hold down clamp (P/N 116-100101-01) when securing the cinema projector to the rack stand.

4. Install and secure the lamp power supply (LPS) in the rack stand: a. Remove the right (the operator's side) panel of the rack stand. b. Remove the cross bar.

WARNING

Figure 2-6 Adjust Feet

2.6 Secure the Cinema Projector

Use of the cinema projector’s rear safety strap is MANDATORY to prevent it from tipping. Secure the strap between the cinema projector and the optional rack stand or any other surface it is mounted to.

2.7 Adjust Tilt and Level the Cinema Projector

The cinema projector’s rear safety strap must be in place before you adjust the cinema projector’s feet.

DO NOT over-extend the feet. Make sure several threads are engaged into

the cinema projector baseplate.

The CP4230 lens should be centered and parallel with the screen. This orientation ensures ideal lens performance with minimal offset. If this position is not possible (such as when the cinema projector is significantly higher than the center of the screen), it is better to rely on offset rather than extra tilt.

Use a protractor to measure the degree of screen tilt and then extend or retract the cinema projector feet to match this angle.

NOTES: The front-to-back tilt of the cinema projector must not exceed 15°. This limit ensures safe lamp operation and the proper positioning of the liquid cooling reservoir.

To adjust the vertical or horizontal position of the cinema projector, extend or retract the adjustable feet on the bottom of the cinema projector by rotating them. Once the required adjustment is made, tighten the lock nut. (Figure 2-6)

If you need to adjust the vertical or horizontal position of the cinema projector beyond what the standard feet allow, you can install two 6 inch extension rods to increase the amount of adjustment. To install the extension rods safely:

1. Prop the rear of the cinema projector up to access and remove the two

rear feet. This can be done by one person holding the back end of the cinema projector up slightly so another person can unthread the feet OR by propping up the back of the cinema projector with a sturdy object.

2. Add the extension rods to the standard feet.

3. Thread the extended feet into the cinema projector’s baseplate. Adjust the feet until the desired tilt is

achieved.

4. Lock the feet in place by turning each lock nut until it fits tight against the cinema projector.

Figure 2-10 Connect Exhaust Ducting

WARNING

Figure 2-11 Exhaust Duct Vane Switch

2.9 Connect External Exhaust Ducting

Connect the existing outside-venting ductwork to the 8 inch diameter exhaust port on the top of the cinema projector. Confirm that there are no obstructions or bends in the ducting, all air intakes are free of obstructions, and the vane switch at the exit duct moves freely.

The pre-installed outside-venting duct should be rigid at the cinema projector and must also include a heat extractor and blower that maintains a minimum of 450 CFM* when the cinema projector is operating at less than or equal to 25°C ambient and less than 3,000 feet, when measured at the cinema projector exhaust opening.

• *600 CFM is required in projection rooms with an ambient temperature above 25°C or located at an elevation greater than 3000 feet above sea level.

• At minimum, a 10” long, strong metal duct must be installed at the cinema projector to prevent glass shards from exiting the duct in the event of a lamp explosion.

2.9.1 Determine the cinema projector Exhaust CFM Value

Use an airflow meter to measure the ft/min or ft/ sec at the rigid end of the open exhaust duct that connects to the cinema projector. Take the measurement at the very end of the duct without the cinema projector connected. Use this formula to determine the CFM value for the cinema projector:

Measured linear ft/min x 0.35 = CFM

regularly verify that the exhaust is functioning correctly.

Never disable the vane switch. Attempting to operate the cinema projector

with inadequate airflow can result in dangerous overheating of the cinema projector.

2.10 Remove the Shroud

T o access the MLM and lens, you need to remove one shroud. You must remove the second shroud when you use a Motorized Auxiliary Lens Mount or Real D Z.

1. Using finger pressure, push down on the locations specified by the red arrows in the diagram.

2. Carefully slide the shroud sideways and forward away from the MLM and lens.

3. Place the shroud cover on a clean surface to prevent scratches.

Section 2: Installation and Setup

2.11 Install the Primary Lens

The lens seals the projection head, preventing contaminants from entering the main electronics area. Do not operate the cinema projector without a lens installed. Install a lens plug when you install or transport the cinema projector.

Never operate a cinema projector without a lens.

To prevent a collision between the projection lens and the Motorized Auxiliary Lens Mount (MALM), move it to the OUT position before you calibrate the lens or perform reset functions. Keep your fingers and other body parts away from the moving parts in the cinema projector. Motors and fans may start without warning. Tie back long hair, remove jewelry and loose clothing before manually adjusting the cinema projector.

NOTE: 1) Make sure the zoom ring is against the front of motor mount for lenses: 1.6-2.4:1, 1.8-3.0:1, 2.15-

3.6:1. 2) Make sure the zoom ring is against the back of motor mount for lenses: 1.45-2.05:1, 1.25-1.83:1. 3) All other lenses: Leave a gap between the rotating zoom section of lens and motor mount.

1. Unpack the zoom motor kit.
