Installation (continued)

21. Raise the screen assembly into the wall opening. On the

projector side, one person will remain holding all three ropes

(N) without slack, guiding the screen into place. On the

audience side, two people will lift the screen vertically, one on

the left and one on the right side. These three people (one

rope control and two lifters) will coordinate together to lift the

screen into place. The fourth person should be on a ladder on

the projector side helping the rope control and lifters guide

the screen assembly into place until all three hoisting and

lifting brackets attach to each other at the top of the wall

opening (See Figure 8).

22. Once the screen is hanging on the hoisting and lifting

brackets, carefully remove the seam (J) and corner (K)

brackets along with the 3/8" screws (L) and nuts (M).

NOTE: During this step, be careful not to touch the projection

coating on the audience facing side of the screen assembly

along the screen edges.

NOTE: At the end of this step, the screen assembly's weight

should be supported by the hoisting and lifting brackets and

it should be centered side to side inside of the wall opening.

Gloves can be removed at this time.
