Warnings Christie stacking hardware is required to prevent the top projector from sliding off the stack. Failure to incorporate this hardware may cause injury or death. This procedure must only be performed by a qualified service technician. The frame is designed to support a maximum stacking capacity of three projectors.

Wait for the internal cooling fans to stop before unplugging the unit. people are required to complete this procedure. 1. Turn the projector OFF and disconnect the AC power cord after the cooling fans have stopped. Allow the projector to cool for at least 45 minutes.

1. Place the first projector in the stack on a secure table or cart. For upright stack: Place the projector to be positioned on the bottom of the stack on the table or cart. Ensure the adjustable feet are NOT retracted on the bottom projector.

For inverted position: Remove the pins from the mounts on the top projector. 5. With one person positioned on each side of the projector, lift the top projector onto the bottom projector, aligning all three stacking points between the projectors. The legs should fit inside the stacking mounts.
Do not mix orientations in a stack (i.e. inverted and upright). Use this procedure to hoist one projector or a stack of projectors. To hoist a stack, first mount two or three projectors according to the stacking procedure included in these instructions.

(two opposite sides). Straps must be placed on either side of designated label on the stacking frame handles. 1. If the projector is inverted retract the adjustable feet to prevent the hoisting hardware from becoming snagged. Always use at least two safety cables when hoisting and attach them to the two eyebolts on the stacking frame.

The four top rigging points have a maximum loading capacity of 800 lbs. each. When hoisting from the bottom of the projector use at least four of the eight rigging points (two opposite sets). Use metric hardware only (M12 thread).

Always use at least two safety cables when hoisting. When hoisting a non-inverted projector or stack, add two rigging eyebolts in the front and rear threaded holes on the top of the projector. Ensure the eyebolts are rated adequately for the load. Secure safety cabling to both eyebolts.
3. Minimize each projector’s zoom until the images are focused. 4. Adjust the zoom and lens offset on the top projector to precisely move its test pattern display onto the bottom test pattern. When it is properly aligned all the Red/Green grid lines in the combined image will turn Yellow.

Refer to Figure 9. 6. Adjust the zoom on the top projector to align the edges of its image with the other image and then adjust focus. When aligned, all lines from the combined Red/Green grids will be Yellow.
