Apply a ¼" continuous bead of pumpable sealant to the back
side of the mounting flange (see figure 3), in line with pre-
punched holes. (Caution: If the window units are pre-sealed prior
to installation, a skin may form on the sealant, causing a potential
for failure. Refer to the sealant manufacturers instructions for
sealant curing time. Be sure to install the window before the
sealant sets up on the mounting flange.)

NSTALLATION
1.
Place the window in the R.O. with the window sill resting on the
R.O. sill. If the R.O. sill is not square to the floor and if you have
elected to shim the window, then place shims beneath the low
corner of the unit until the sill of the unit is square. Shims must
be placed beneath the extreme corners of the window frame;
additional shims must be placed every 12" on center to fully sup-
port the weight of the unit. Shims may be used at the
frame/jambs if these frame/jambs are not straight and plumb; use
enough shims to straighten and plumb the frame/jambs. Shims
should not be used at the frame head of a unit; if R.O. header
deflects, building loads will be transferred to window, causing
improper operation or failure of window.
2.
Center the window from left to right but do not remove the sill
from contact with the R.O. sill and any shims that were required to
square the sill of the unit. When installing windows it is required
to use corrosion resistant fasteners that produce a minimum of 1"
penetration into the framing members.
3.
While holding the window flat against the exterior of the wall, start
a fastener in the approximate center of one of the frame/jamb
mounting flanges. Continue installing fasteners in the following
order; center of opposite frame/jamb, center of head and center of
sill. Note: If scaffolding interferes with the top of the window, it is
acceptable to install this later when it is more accessible.
Warning: Do not over drive fasteners, to do so
will fracture or unduly deform the mounting
flange and compromise the seal. Use caution in cold
weather when installing fasteners through the nailing
fin, the vinyl material becomes more brittle as
temperatures decrease. Do not apply fasteners
or staples through any other surface of the
window other than the Philips specified areas
and/or the mounting flange. Failure to comply
may void any manufacture warranty.

Warning: Fenestration products are not to be used with
corrugated metal siding.
5.
After the fasteners have been installed through the midpoint of
each mounting flange, it is recommended that you re-check the
window to be certain it is centered from side to side in the
opening, and that the window frame members are straight and
that the window frame is square, (measure opposite corners of
the window frame in a manner similar to measuring the diagonals
of the R.O., it should be within 1/8"). Before proceeding, it is
recommended that you check to ensure window operates
properly. If it does not, remove fasteners and reinstall window as
per above instructions. If shipping block(s) is present, remove at
this time.
