INSTALLATION NOTES
1. Do not drop, roll or drag boxes of aluminum framing. Move and stack boxes with proper
support to prevent distortion. If fork lifts are used, be especially careful about striking the
boxes when lifting or moving.
2. Store in a dry, out of the way area. If rain exposure, condensation or any water contact is
likely, then all packaging material should be removed. Wet packaging materials will discolor
and may stain aluminum finishes and paints.
3. All materials should be checked for quantity and quality upon receipt, YKK AP must be
notified immediately of any discrepancies in shipment. Check to make sure that you have the
required shims, sealants, supplies, and tools necessary for the installation.
4. Carefully check the openings and surrounding conditions that will receive your material.
Remember, if the construction is not per the construction documents, it is your responsibility
to notify the general contractor in writing. Any discrepancies must be brought to the general
contractor’s attention before you proceed with the installation.
5. Collect your shop drawings, materials, packing list, and this installation manual.
Carefully review parts location, the sequence of installation, when you glaze it, and how you
seal it. Installation instructions are of a general nature and may not cover every condition you
will encounter. The shop drawings and/or installation manuals were prepared specifically for
the product.
6. Any material substitutions must be of equal or greater quality.
7. Make certain that material samples have been sent for compatibility and adhesion testing for
all manufacturer’s sealants involved. Make certain that sealants have been installed in strict
accordance with the manufacturer’s recommendations and specifications.
8. Consult sealant manufacturer for proper sealant and backer rod selection.
A. Large Missile: Use only Dow Corning 995 Structural Silicone
9. Remember to isolate, in an approved manner, all aluminum from uncured masonry or
other incompatible materials.
10. System-to-structure fasteners are not supplied by YKK AP. Fasteners called out on shop
drawings are to indicate minimum sizes for design loading.
11. If any questions arise concerning YKK AP products or their installation, contact YKK AP
for clarification before proceeding.

YOW 225 TUH Window System
INSTALLATION NOTES
12. YKK AP window installation is typically completed before drywall, flooring and other
products which may still be in process. Take the extra time to wrap and protect the installed
material.
13. Cutting tolerances are plus or minus one thirty second of an inch (1/32”) unless otherwise
specified.
14. YKK AP Model YOW 225 TUH windows are prefinished, prefabricated, and preassembled
products, and must be protected against damage.
15. Concrete, mortar, plaster, muriatic acid and other alkaline and acid based construction
and cleaning materials may be very harmful to window finishes and should be removed with
water and mild soap immediately or permanent damage or staining of the finishes will occur.
A spot test is recommended before any cleaning agent is used, and abrasive type cleaners
must never be used.
16. Windows are never to be used as ladders, step stools, scaffolds or scaffold supports.
17. All work must start from and be referenced to benchmarks, offset lines and/or column
centerlines established by the architectural drawings and the general contractor.
18. All windows must be installed plumb, square, and level, and in accordance with approved
shop drawings and these installation instructions.
19. Glass and glazing building codes governing the design and use of products vary widely.
YKK AP America Inc. does not control the selection of products, product configurations,
operating hardware and function, or glazing materials, and YKK AP assumes no responsibility
for these design considerations. It is the responsibility of the design professional, owner,
architect, specifier, general contractor, and the installer to make these selections in strict
accordance with all applicable codes.
20. For projects that require a Florida product approval compliance letter or installation drawings, refer to the floridabuilding.org website. Contact YKK’s Engineering Center for specific
product approval numbers.
21. Check our website, www.ykkap.com, for the latest installation manual updates prior to
commencing work.
8. Consult sealant manufacturer for proper sealant and backer rod selection.
A. Small Missile: Dry Glaze interior, YKK AP approved structural silicone for exterior cap
bead.
B. Large Missile: Use only YKK AP approved structural silicone.
Page 8, step 9 calls for Tremco Tremsil® 600 sealant or equal.

INSTALLATION
STEP 1
DETERMINE WINDOW REFERENCE POINT
Establish the window reference lines or the exterior/interior plane of the windows to be installed
using either bench marks, offset lines, or column centerlines provided by the general contractor
and referenced on the shop drawings. Use the established reference points to determine the
installation points for each window opening at the head, jambs, and sill.
STEP 2
DETERMINE TYPE OF ANCHOR FASTENER TO BE USED
-Fastener size and location to be determined by engineering calculations.
-For Dade County installations refer to the table below for minimum anchoring requirements.
Steel strap anchors are available and when used, must be installed:
-A minimum of 3” from the corner of all frames.
-At 15” on center.
-A maximum of 3” on each side from the centerline of ventilator locking points.
-A maximum of 3” from the edge of framing joints, or mullions.

operation of locking devices and the compression of the weather seal.
-All hardware must be cleaned and lubricated as necessary to provide smooth operation.

1. Verify that the frame and vent are properly
aligned with a 1/8” margin around the entire
perimeter of the vent.
2. Remove the glazing beads and clean the
exterior glazing leg with an approved cleaning

tape and the edge of the ventilator.
-Make certain that the corners of the tape
do not overlap as this will prevent full
contact around the perimeter of the glass.

pressure so that the silicone sealant completely fills the
cavity.
12. Using a nylon or teflon spatula or other non-scratching
implement, tool the silicone sealant immediately after
running the joint. Exert positive pressure while tooling to
ensure that the silicone sealant makes complete contact
with all surfaces.Be careful not to remove too much silicone.
13. Remove masking tape within ten minutes of tooling.

Install mullion end cap, E1-1536, to each end of the stacking mullion with a PC-1006-SS fastener.
Attach anchor clips to what will be the open side of the stacking mullion:
-Attach anchor clip, E1-1537, to the top and bottom of one side of the stacking mullion such
that each clip extends 1/4” past the end of the mullion.
-Attach anchor clips with two PC-1208-SS fasteners at each end (do not completely tighten yet).
Install the stacking mullion into the opening according to Detail 15:
-Slide each anchor clip tight against the masonry.
-Attach each anchor clip to the masonry with two flat head fasteners.
-Now completely tighten the PC-1208-SS fasteners used to attach the anchor clips to the
mullion.
Carefully slide the second window assembly in and anchor it to the masonry.
To ensure a watertight seal run a bead of sealant up each interior frame jamb at the stacking
mullion. Additionally, run a cap seal along the joint between the exterior frame jambs and the
stacking mullion. If the exterior of the window is inaccessible, run a bead of sealant along the
backside of each stacking mullion leg prior to installing the windows into the stacking mullion.
Attach the pressure plate, AS-4231, to the stacking mullion:
-Install HM-2516-W3 fasteners at 1-1/2” from each end maximum and then 9” on center.
Pressure plates are pre-drilled; drill additional 0.281” diameter (#9/32) holes if necessary.
-Start installing fasteners at the center of the pressure plate and work towards each end.
-Torque each fastener to 50 inch pounds.
Install PC-1008-SS fasteners, one on each side, through the pressure plate into the window frames:
-(2) 6” below the top of the frame.
