A. Install 2" x 6" cross braces between rafter tails, directly above

the cable holes in the bay/bow head board.

B. Install the cable clamps directly above the "T" nuts where

adequate support is available. Holding the clamp parallel to the up-running cable, drive the #12 x 3-1/4" square drive screws part way into the mounting surface using a #3 square drive bit.

C. Run the cable up through the bottom of the cable clamp.

Hold the cable up tight above the clamp and drive the two center clamp screws all the way in, locking the cable in place. Drive the remaining #12 x 3-1/4" square screws all the way.

Note: Make sure all four screws are driven in at maximum torque. Additional tensioning may be done with the nuts on the opposite end of the cable at the bottom of the bay/ bow unit.

CROSS BRACING MOUNT - NON ACCESSIBLE CABLE ATTACHMENT

Note: Install the cable clamp and cable prior to installing the bay/bow unit.

A. Install 2 x 6 cross braces between the rafter

tails, directly above the cable holes in the bay/ bow head board.

B. Remove the cable from the bay/bow unit.

Measure the distance from the bottom of the cable clamp to the bottom of the header plus 3/8" head clearance (A dimension). Measure the height of the unit from the top of the head board to the bottom of the seat board (B dimension). Add "A" to "B" plus 1", to get the correct length of cable hanging from the bottom of the cable clamp. Insert the cable end through the round hole of the cable clamp. Ensure the correct length of cable is hanging below the bottom of the cable clamp. Tighten the two cable clamp corner screws. Insert one screw into each of the center holes in the cable clamp, and tighten to fully clamp the cable in position.

A. Tighten the top hex nut on both cable ends. Using a 3/16" wrench or socket, hold the

cable end in position while tightening the top hex nut with a 1/2" wrench or socket. is will keep the cable from twisting as the hex nuts are tightened.

B. Remove the temporary bracing. Check the window for level, plumb, sash reveal and

operation. Readjust, if needed.

Note: Be sure to use the temporary support when readjusting the hex nuts.

C. Remove blocking from under the seat board.

D. Tighten the locking (bottom) nut on both cable ends and

remove the temporary support once the nal position is found. DO NOT cut the threaded end o the cable as this will prevent future adjustment should it be needed.

E. Installation of knee braces is recommended to help support

the weight of the bay/bow unit. Weight calculations must take into account the weight of the items that may be placed on the seat board of the bay/bow unit. If the upper roof/framing members are not capable of supporting 1,300 lbs. or if more than 500 lbs. will be put on the seat board, knee braces must be used in addition to the cables.

INSULATING FOAM APPLICATION

Caution: Ensure use of low pressure polyurethane window and door insulating foams

ALLALLALLALLALLALLALLALLALLALLALLALL

and strictly follow the foam manufacturer’s recommendations for application. Use of high pressure foams or improper application of the foam may cause the window frame to bow and hinder operation.

A. Apply insulating foam sealant. From the interior,

insert the nozzle of the applicator approximately 1" deep into the space between the window and the rough opening and apply a 1" deep bead of foam. is will allow room for expansion of the foam and will minimize squeeze out. If using foam other than Great Stu Sealant by the Dow Chemical Company, allow the foam to cure completely (usually 8 to 24 hours) before proceeding to the next step.

Note: It may be necessary to squeeze the end of the tube with pliers to be able to insert into the space between the jamb boards and the rough opening, and between the head and seat board and the rough opening.
