1PREPARE THE OPENING

2PREPARE THE WINDOW FOR INSTALLATIONA. Remove packing materials from window(s). DO NOT remove shipping spacers. The shipping spacers will help keep the window

square during installation.

C. Verify that the window(s) will fit into the opening.

Two or more people will be required for the following steps.

If transoms are to be attached (mulled) to the top of the units, perform MULLING WINDOWS TOGETHER on the back of this sheet. PERFORM THIS PROCESS BEFORE INSTALLING CLIPS.

For installation using screws through the jamb, go to INSTALLATION INSTRUCTIONS USING FRAME SCREWS on the back of this sheet. For installations using installation clips, use the following steps.

A. Prepare the window opening as required to allow the window to fit into the opening.

B. Verify the opening is plumb, level, and square. Fix any problems with the opening before proceeding.

D. Install and level sill spacers. Place 1" wide by 1/4" thick spacers on the bottom of the window opening 1/4" from each side. Spacers are also required at the interlocker. Add shims as necessary to ensure the spacers are level. Once level, attach spacers and shims to prevent movement.Note: Improper placement of shims or spacers may result in bowing the bottom of the window.

B. Install installation clips. Slide clips into the window frame sill groove, placing one clip 6" from each end of the unit and no more than 16" on center.Note: When applying clips to mulled units, clips should be placed 6" from each end and 6" on each side of the mullion joint. Add clips where the spacing between clips is more than 16".

C. Slide clips into the window frame jamb grooves. Use the same spacing as step 2B.

D. Slide clips into the window frame head grooves. Use the same spacing as step 2B.

Note: If there are any problems with the operation of the window, recheck shim locations and adjust for plumb and square.

E. Check window operation. Open and close the window a few times to check for proper operation. Close and lock the window.

C. Fasten the window to the opening by driving 1-1/4" or longer concrete screws into the pre-punched holes in the clips.

D. Remove the plastic spacers located between the bottom of the vent sash and the frame sill.

3SETTING AND FASTENING THE WINDOWA. Slide the window into the opening, placing the bottom of the window on the spacers at the bottom of the opening. Center the

window between the sides of the opening to allow clearance for shimming, and insert one 1-1/4" or longer concrete screw into one hole in each of the top clips. This will hold the window in place while shimming it plumb and square.

Note: Do not shim above the window or in the space between the spacers at the bottom of the window. DO NOT OVER SHIM.

B. Place shims 1" from the bottom and top of the window between the window and the sides of the opening. Adjust the shims as required to plumb and square the window in the opening. Also shim at the transition bar of multiple sash units. Interior

Note: When applying siding, brick veneer or other exterior finish materials, leave adequate space between the window frame and the material for sealant. Refer to the illustration that corresponds to your finish material. Not allowing adequate space or not using backer rod may cause the sealant to break down prematurely and allow water to infiltrate.

Note: Backer rod adds shape and depth for the sealant line.

A. Insert closed cell foam backer rod into the space around the window. This should provide at least a 1/2" clearance between the backer rod and the exterior face of the window.

Note: This method creates a more flexible sealant line capable of expanding and contracting.

C. Shape, tool and clean excess sealant. When finished, the sealant should be the shape of an hourglass.

B. Apply a bead of high quality exterior grade sealant to the entire perimeter of the window.

5INTERIOR SEALCaution: Ensure use of low expansion polyurethane window and door installation foams and strictly follow the foam manufacturer’s recommendations for application. Use of high expansive foams or improper application of the foam may cause the window to bow and hinder operation.

B. Check window operation by opening and closing the window.Note: If the window does not operate correctly, check to make sure it is still plumb, level and that the sides are not bowed. If the sides are bowed, remove the foam with a serrated knife and repeat the above steps.

Note: DO NOT completely fill the space from the back of the fin to the interior face of the opening. Over filling the space may cause the window frame to bow.

A. Apply insulation foam. 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. This will allow room for expansion of the foam and will minimize squeeze out. Allow the foam to cure completely (usually 8 to 24 hours) before proceeding to the next step. Interior

5A

A. Insert the window from the exterior of the building and center the window between the sides of opening to allow clearance for shimming.

Note: For windows with frame width greater than 48”, install installation clips on the head and sill. Install one clip 6” from each end, then install additional clips not more than 16” on center.

G. Insert jamb hole plugs (provided).

H. Proceed to Step 4.

C. Fasten the window at the top of the opening by driving 2-1/2" long screws (provided) through the top 2 holes in the window sides, and into the wall members.

F. Check the window operation by unlocking, opening and closing the sash. If the window does not operate smoothly, check and adjust the shims.

D. Plumb and square the window. Insert shims, as necessary, between the window and the sides of the rough opening at the anchor hole locations in the window sides. (DO NOT over shim).

E. Fasten the window in the opening by driving the 2-1/2" long screws (provided) through the holes in the window sides, through the shims and into the wall members.

B. Insert shims between the window and the sides of the rough opening at the top 2 anchor hole locations in the window sides. Remove the plastic spacers located between the bottom of the vent sash and the frame sill.Note: Unlock the window and open the vent sash to access the anchor hole on the vent side of the frame.
