Installation (continued)

23. At the top section, align the T-track and the frame. Insert eight

tensioning assemblies (O) (four per frame section for larger

screens). Align the tensioning assemblies (O) so that they are

evenly spaced across the length of T-track and frame (See

Figure 9)

24. Tighten a minimum of two tensioning assemblies (O) per

frame section between the T-track and frame using a 1/2"

wrench. After two or three turns on one tensioning assembly,

move to another in order to prevent the bolts and nuts from

binding. Keep using this alternating method until at least two

(or more) tensioning assemblies, per frame section, have

secured the frame to the T-track on the top section of the

screen assembly. As the tensioning assemblies are tightened

the screen frame will pull gradually closer to the T-track. Do

not tighten fully at this time.

CAUTION: Do not proceed to next steps until a minimum

of two tensioning assemblies (O) per frame section are

attached fully and are holding the screen weight on the

top side.

25. Remove the three lifting brackets (D) from the wall opening

behind the T-track by loosening and removing the 1/4" x 1" lag

screws. The three ropes (N) should also be removed at this

time.

NOTE: Once the lifting brackets have been removed, the

screen assembly will be held in place by the previously

attached tensioning assemblies.

26. Tighten all tensioning assemblies (O) on the top section of

the screen assembly until all eight (four per frame section)

are evenly spaced and secure on the top side.

NOTE: Use the alternating method of two to three turns on

one assembly then moving to another assembly to prevent

the bolts and nuts from binding.

27. At the bottom section, align the T-track and the frame. Insert

eight tensioning assemblies (O) (four per frame section for

larger screens). Align the tensioning assemblies (O) so that

they are evenly spaced across the length of T-track and

frame.

28. Begin tightening the tensioning (O) assemblies between the

T-track and frame using a 1/2" wrench. After two or three turns

on one tensioning assembly, move to another in order to

prevent the bolts and nuts from binding. Keep using this

alternating method until the tensioning assemblies have

secured the frame to the T-track.

NOTE: These tensioning assemblies (O) do not need to be

tightened down completely (no threads showing) because

the top frame is already anchoring the screen in place. The

bottom needs to be secure enough to the installer's

discretion.

29. Repeat Steps 27 and 28 for the left and right sides of the

frame, using four tensioning assemblies (O) per frame

section.
