General
The IWS-H Series Wall Sleeve is designed for use with I-TEC Series heat
pumps and air conditioners. The wall sleeve assembly consists of a large
intake sleeve and a smaller exhaust sleeve. Both sleeves are telescoping to
adjust for different wall depths (see Figure 1 on page 4 and Figure 2 on page
5). The IWSH Series Wall Sleeves are designed to be used with 4″ or 8″
louvers (see Table 1). A louver is not included with the IWS-**H Wall Sleeve.
The equipment covered in this manual is to be installed by trained service and
installation technicians. These instructions explain the recommended method to
install the wall sleeve. These instructions and any instructions packaged with
any separate equipment required to make the entire air conditioning system
should be carefully read before beginning the installation.
While these instructions are intended as a general recommended guide, they do
not supersede any national and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is made.

INSTALLATION
Installation – Wood Framed Walls
For wood frame construction walls, the minimum dimensions of the opening must
be 48-1/4″ inches tall by 42-3/4″ inches wide. A 2 x 6 header will be required
for the opening. The sides of the opening must have trimmer studs to support
the header and to provide a structural member on which to fasten the sleeve
(see Figure 4). All of the dimensions are referenced from the finished floor
height. If a riser platform accessory is used, adjust dimensions accordingly.
Once the opening is framed, the sheeting can be installed. The sheeting
material must not extend into the opening.
The intake sleeve should be test fit into the opening to make sure of the
dimensions. 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 two 1/4″ beads of sealant must be applied to
the mounting flanges of the sleeve (see Figure 5).
The sleeve is then reinserted 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 (2) field-supplied wood 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 ten (10)
field-supplied wood screws through the holes in the flanges.
The inner portion of the intake sleeve must be inserted from the inside of the
building. While holding the flanged side of the sleeve, slide it into the
outer sleeve and insert far enough so it projects approximately 1/2″ from
either the smooth wall surface or from the sill. Final adjustment must be done
from the outside.
On the inside of the building, the gaps between the sleeve and the rough wall
opening must be filled with insulation.
NOTE: If foamed insulation is used, the final location of the inner
sleeve must be determined since the foam insulation could lock the inner
sleeve into an incorrect location causing either an air leak between sleeve
and back of unit or preventing the unit from going as tight to the wall or
sill as desired. This must be done before the unit is placed and before the
inner portion of the intake sleeve is secured with screws to the outer sleeve.
Insulating this space will prevent infiltration of any unwanted outside air
(see Figure 7 on page 8).
If the I-TEC unit will be drained through the
wall, the drain line must be installed prior to setting the unit.
Information for the drain installation is provided in the installation
instructions supplied with the unit. At this point, the following are options:
-
Install the weatherization plate, if the I-TEC unit is not ready to be installed.
NOTE: The exhaust sleeve attaches to the I-TEC unit. Store it and any remaining mounting hardware in a safe location. -
Proceed to instructions on page 8 for attachment of the wall sleeve to the I-TEC unit.
Installation – Masonry Construction Walls
For masonry construction walls, the minimum dimensions for the opening will be
48-1/4″ tall by 42-3/4″ wide (see Figure 6). These dimensions are measured
from the finished floor height. These will be the finish dimensions of the
opening.
The intake sleeve should be test fit in the opening before final preparations
are made. The sleeve will be installed into the opening from the outside of
the building in. The sleeve must be centered in the opening from side to side.
The mounting flanges of the sleeve must contact the outside wall all around
the opening.
The side and top mounting flanges must have the mounting holes drilled into
the outside wall for the concrete anchors which will hold the sleeve in the
wall.
The holes should be drilled through the holes in the sleeve with the sleeve
level and 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 fitting has been checked out, the
sleeve should be removed from the wall.
With the sleeve removed, two 1/4″ beads of sealant must be applied to the
flanges that contact the outside wall (see Figure 5).
The sleeve must be installed back in the wall making sure that the predrilled
holes in the wall line up with the holes in the mounting flanges of the
sleeve. Check to make sure that there is enough sealant between the wall and
the flanges to make the joint watertight.
Additional sealant must be applied as required. The sleeve must be anchored to
the wall. All four mounting flanges must be fastened to the outside wall using
twelve (12) field-supplied masonry screws.
The inner portion of the intake sleeve must be inserted from the inside of the
building. While holding the flanged side of the sleeve, slide it into the
outer sleeve and insert far enough so it projects approximately 1/2″ from
either the smooth wall surface or from the sill. Final adjustment must be done
from the outside.
On the inside of the building, the gaps between the sleeve and the rough wall
opening must be filled with insulation.
NOTE: If foamed insulation is used, the final location of the inner
sleeve must be determined since the foam insulation could lock the inner
sleeve into an incorrect location causing either an air leak between sleeve
and back of unit or preventing the unit from going as tight to the wall or
sill as desired. This must be done before the unit is placed and before the
inner portion of the intake sleeve is secured with screws to the outer sleeve.
Insulating this space will prevent infiltration of any unwanted outside air
(see Figure 7).
If the I-TEC unit will be drained through the wall, the drain line must be
installed prior to setting the unit. Information for the drain installation is
provided in the installation instructions supplied with the unit. At this
point, the following are options:
-
Install the weatherization plate, if the I-TEC unit is not ready to be installed.
NOTE: The exhaust sleeve attaches to the I-TEC unit. Store it and any remaining mounting hardware in a safe location. -
Proceed to instructions below for attachment of the wall sleeve to the I-TEC unit.
Attachment of Wall Sleeve to I-TEC Unit (3-Piece Severe Duty Louver Shown)
-
Prepare wall opening per wood framed or masonry construction instructions (see pages 6 and 7). Install sleeve in opening; be sure to apply a bead of silicone sealant behind mounting flange (see Figure 5).
-
Extend inner intake sleeve beyond inner wall surface by 1/2″. Attach inner intake sleeve to outer intake sleeve using six (6) 5/16″ x 3/4″ self-tapping screws (supplied), three (3) along each side (see Figure 8).
Use silicone sealant to caulk the seam between the inner intake sleeve and outer intake sleeve. -
Install 3-piece louver (not supplied). Holes will need to be drilled where required to bolt louver to structure per specified building codes.
-
Remove center section of louver.
-
Move the I-TEC unit into place ensuring it is aligned side to side. Push unit back until the side panels are flush with the wall or until the sides contact the window sill (if applicable). Foam gasket on sleeve should be compressed between sleeve and unit. Attach inner intake sleeve to the rear of the unit with twelve (12) 5/16″ x 3/4″ self-tapping screws (supplied), using care to avoid damaging the gasketing material.
-
Install exhaust sleeve to unit fan shroud using six (6) 5/16″ x 3/4″ non-tapping screws (supplied) as shown in Figure 8. Pull inner exhaust sleeve frame out until flush with back of louver. Attach inner exhaust sleeve to outer exhaust sleeve using four (4) 5/16″ x 1/2″ non-tapping screws (supplied).
