Installation Through a Window
Opening
NOTE: Depending on the window sill height as
measured from the inside finished floor, a spacer may
be required under the unit wheels to ensure the proper
relationship from the bottom of the sleeve and the
window sill. To determine the height of this spacer,
measure the window sill height from the finished
floor, add 2.5" and subtract 32.75". Example: With
a sill height of 33", add 2.5" and subtract 32.75".
This equals a spacer height of 2.75". This spacer is
to continue across the front of the unit to seal up the
gap between the floor and the bottom trim piece. When
the unit is placed on these spacers, the locking screws
must be driven back into the wheel to secure the unit's
position. Also, there are two brackets used for securing
the sleeve to the unit. These brackets are shipped with
the unit. Proper attachment at the proper location can
be seen in Figure 5.
The QWVS42, QWVS42-19 and QWVS42-H may be
used when the installation is through an existing
window opening.
A 2.5" spacer is to be placed on the window sill. This
spacer must be weather resistant and attached to the
window sill. See Figure 5 for the location of this spacer.
The QWVS42, QWVS42-19 and QWVS42-H must
extend through the window opening on the inside wall
by 4" to allow clearance between the unit and the wall
for the water pipes.
The window opening can be framed to provide an
opening for the sleeve, 35" wide by 29.5" tall. The
height of the opening is measured from the top surface
of the 2.5" spacer. Once the opening is framed, the
sheeting can be installed. The sheeting material must
not extend into the opening.
The sleeve should be test fit into the opening to
confirm the dimensions are correcct. The sleeve must
be inserted into the opening from the outside of the
building. The bottom of the sleeve must be level from
side-to-side and the sleeve must be square in the
opening. A slope is built into the bottom of the sleeve
from the inside to the outside. This will allow any water
that gets into the sleeve to drain out. Once the test fit
is completed, the sleeve must be removed from the
opening and 1/4" bead of sealant must be applied to
the mounting flanges of the sleeve (see Figure 2).
The sleeve is then re-inserted into the prepared opening
from the outside of the building. All of the mounting
flanges must contact the exterior wall. Check to see that
there is enough sealant to make this joint watertight.
Additional sealant must be applied as necessary. The
sleeve must be centered in the opening and the bottom
of the sleeve must be checked to make certain that it
is level from side-to-side. The bottom flange should be
secured to the wall by using two screws through the
holes in the bottom mounting flange of the sleeve. The
sleeve must be checked to make sure that it is square
in the opening. Once the sleeve is square, the side and
top mounting flanges of the sleeve must be secured to
the wall with screws through the holes in the flanges.*
The gaps between the side, top and bottom flanges
must be filled with additional sealant.
There are two brackets supplied with the unit for
attachment to the sleeve. Position these brackets to
the sleeve and attach with three screws per side. Roll
unit up to sleeve making sure the rear of the cabinet is
tight against the gasket on the sleeve flange to provide
an air tight seal. Drill 1/8" diameter holes through the
brackets in to the cabinet side and attach with screws
provided. See Figure 5 for more detail.
* Model QWVS42-H is not secured to the wall by
the flanges. Instead, it is secured along with the
hurricane grille through the sides of the sleeve per
requirements.
