- Remove inlet sleeve, with weatherization plate attached, from the carton and turn over.
- Remove and save the four (4) screws attaching the security plate.
General
The IWS-23 Series wall sleeve is designed for use with the I-TEC Series heat
pump. The wall sleeve assembly consists of a large intake sleeve, smaller
exhaust sleeve and an adapter curb. Both sleeves are telescoping to adjust
for different wall depths. See Figures 1 and 2 on pages 4 and 5.
The adapter curb is 4″ deep and allows the smaller sleeve to be used. When
using this sleeve and adapter, the unit will be 4″ from the indoor wall
surface, and an ILST trim kit will be needed.
These instructions explain the recommended method to install the wall sleeve.
The equipment covered in this manual is to be installed by trained service and
installation technicians.
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 intended as a general recommended guide, these instructions do not
supersede any national and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is made.
Side Angle Relocation for ILA-2 Louver
The IWS-23 wall sleeve is designed for use with both 1″ and 2″ louver depths.
As shipped, the sleeve is ready for 1″ louver installation. Refer to Figure 3
on page 6 for angle installation instructions for 2″ louver depth.
IMPORTANT
IWS-23 wall sleeves are not recommended for use with the I-TEC Series I48 and
I60 heat pump products. Using the IWS-23 wall sleeve with I48 or I60 products
will result in lower condenser airflow.

INSTALLATION
Installation – Wood Framed Walls
See Figure 4 for wood frame construction wall opening dimensions.
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 on page 8).
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 (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 ½” 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 foam 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 10). 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 main installation instructions manual 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 Attachment of Wall Sleeve to I-TEC Unit (see page 10).
Installation – Masonry Construction Walls
See Figure 6 for masonry frame construction wall opening dimensions. These
dimensions are measured from the finished floor height. These will be the
finish dimensions of the opening.
The 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.
FIGURE 6
Masonry Construction Installation
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 ½” 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 foam 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 10).
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 main installation
instructions manual 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 Attachment of Wall Sleeve to I-TEC Unit (see page 10).
FIGURE 7
Typical Installation
Attachment of Wall Sleeve to I-TEC Unit
Move the unit into place ensuring it is aligned side to side. Push it back
until the side panels are flush with the wall, or until the sides contact the
window sill—if that is the case. From the outside of the building, push the
inner sleeve inward until the foam gasket contacts the unit. Attach the sleeve
to the rear of the I-TEC using the twelve (12) ¾” long self-tapping screws
supplied with the sleeve (see Figure 8, REF. B).
Tie the inner and outer sleeves together with the three (3) ¾” long self-
tapping screws on each side (see Figure 8, REF. A). Apply a bead of caulk to
the entire perimeter seam between the inner and outer sleeves (see Figure 8,
REF. A).
The exhaust sleeve has three (3) screw slots in each side flange. Line these
up with the screw engagement holes in the fan panel. Attach using six (6) ¾”
long sheet metal screws supplied with the sleeve (see Figure 8, REF. C).
Extend the sleeve out until it is flush with the louver attachment angles.
Lock the sleeve in place using two (2) ½” long sheet metal screws on each
side by shooting through the slot into a pre-punched hole (Figure 8, REF. D).
Use 1-½” long screws supplied to attach louver to outer sleeve (See Figure 8,
REF. E).
