Installation
Masonry Thick Wall
Construction Sleeve Installation
Typical installation for masonry walls is
shown in drawing below.
IMPORTANT: Depending on the size and
style of the louver chosen, you should
determine whether it can be installed before
or after the sleeve installation.
1. Clean the opening of all debris that may
interfere with installation.
2. Be sure the unit’s center of gravity falls
within the load bearing surface of the
wall. If the center of gravity is not within
the load bearing surface, then additional
support such as wood, metal or concrete
must be provided in the field.
3. Place a thin pad of soft mortar on the
bottom of the opening.
IMPORTANT: Make certain the wall
sleeve protrudes into the room a
minimum of 1 1/8” beyond the finished
wall surface to accommodate the heat
section and room cabinet. Be sure
to recess the wall sleeve enough to
accommodate outside louver. This
recess is required for stamped louvers
and for architectural louvers. The louver
should be flush to exterior surface when
completed.
4. If a brickstop is employed, slide the
wall sleeve into the wall until the
brickstop contacts the exterior bricks.
If a brickstop is not used, slide wall
sleeve into the wall so it extends into the
room a minimum of 1 1/8” beyond the
finished interior wall surface. The wall
sleeve should also be recessed enough
to accommodate the outside louver.
5. After mortar has dried, remove the

Panel/Window Wall
Construction Sleeve
Installation
Standard wall sleeves are designed to be
easily installed. For panel wall and thin wall
construction, the (optional) top angle should
be used and the wall sleeve supplied with a
turned down flange.
IMPORTANT: Depending on the size and
style of the louver chosen, you should
determine whether it can be installed before
or after the sleeve installation.
1. Clean the opening of all debris that may
interfere with installation.
2. Recess the wall opening so that the
louver is flush with the exterior of the
building. Locate the center of gravity
(approximately 10 3/4” from rear
face of standard wall sleeve). If wall
sleeve has been installed into a thick
wall, make certain that the wall sleeve
protrudes into the room a minimum of
1 1/8” beyond finished wall surface to
accommodate heat section and room
cabinet. If a subbase is not used, field
support (metal, wood or concrete) must
be provided to balance the center of
gravity.
3. Level wall sleeve in all directions and
anchor with appropriate fasteners. Use
holes provided or drill additional holes
as required to secure firmly. DO NOT
drill holes in base of the wall sleeve.
Use shims between wall and wall sleeve
to prevent wall sleeve distortion during
anchoring.

Sleeve Installation with Field-
Supplied Louvers
Installation of wall sleeves with continuous
louvers is very similar to that of applications
with factory furnished louvers.
IMPORTANT: Louvers supplied by other
manufacturers must have 70% free area or a
pressure drop not exceeding 0.05 in. w.g.
(12.45 Pa) at 300 fpm (1.524 m/sec)
face velocity, and a blade design that will
not cause recirculation of air. Ice Air does
not warrant the rain and water leakage
resistance of its equipment when used with
louvers supplied by others. All louvers by
other manufacturers must be approved by
qualified installer prior to installation.

Due to Ice Air’s ongoing product development programs, the information in this document is subject to change without notice.
9
Installing the Louver
(Optional)
The louver directs condenser airflow and
provides a protective barrier for the
outdoor coil.
IMPORTANT: Depending on the size and
style of the louver chosen, you should
determine whether it can be installed before
or after the sleeve installation.
1. Install four threaded studs into threaded
openings on the inside face of the louver.
2. Install a washer and one hex nut to the
end of each stud.
3. Manipulate the louver out through rear
wall sleeve opening. Keep a firm grip on
louver to prevent causing possible injury
or property damage.
4. Attach the louver to the wall sleeve
by aligning and inserting the hex nut
threaded onto the studs through the
holes in the wall sleeve.
5. Secure the louver to the wall sleeve by
tightening the hex nut and adding and
tightening an additional hex nut.

Left Lateral Duct Kit
Right Lateral Duct Kit
Installing Lateral Duct Kit
(Optional)
The lateral duct kit allows the air from one
PTAC unit to be shared by an adjacent room.
Called Air Span™, the kit mounts to the top
of the unit and can be configured for either
right or left discharge as shown in drawings
at right. The amount of air diverted to the
second room is adjustable.
1. The kit consists of a main duct for the
installed room, an extension duct to
reach the adjoining room, and terminal
duct.
2. Drill mounting holes on both sides of
the wall sleeve. The minimum required
clearance distance between the wall
sleeve and floor wall is 3”. The minimum
clearance between the wall sleeve and
adjacent (perpendicular) walls is 0”.
3. If the distance between wall sleeve
and adjacent wall will be at or near the
minimum clearance distance, mount
these kits on the sleeve before installing
the sleeve in the wall.
Note:
If the thermostat will be mounted in the enclosure tray,
installer must drill a hole through the enclosure frame.
This will allow access for wiring harness to pass through
enclosure frame to mounting tray. Drilled hole should be
located directly below mounting tray where thermostat is
mounted. Be sure drilled holes have no sharp edges as
they could cause damage to wiring harness. Drilled hole
is not required for wall mounted thermostat.

Twelve (12) Month Warranty of entire
Packaged Terminal Equipment
Ice-Air, LLC (“Ice Air” or the “Company”) warrants, solely
to the person or entity that directly purchased the packaged
terminal system from the Company (the “Original Owner”), that
the entire packaged terminal system is free from defects in
material and workmanship for a period of twelve (12) months
from the date of delivery (the “Twelve Month Warranty”).
Any part or portion thereof which becomes defective under
normal use during the period of this warranty will be repaired
or replaced, provided Ice Air’s examination shall prove to
its satisfaction that the part was or became defective under
normal use. Ice Air’s obligations under this warranty are
subject to the satisfaction of the conditions set forth in the last
paragraph of this Section and are limited to: (a) repairing the
defective part or (b) furnishing a replacement part provided
the defective part is returned to Ice Air, without shipping
damage, transporting charges prepaid. No reimbursement will
be made for expenses incurred in making field adjustments or
replacements unless specifically authorized in writing by the
Company.
Except as otherwise provided in the last sentence of this
paragraph, the Company is not obligated under this warranty
for field labor such as service for inspection, removing,
packing and/or reinstalling water source unit, nor for the
return transportation charges. In addition, the Company is not
obligated under this warranty to make reimbursement of the
labor or service charges of any other party. Notwithstanding
the foregoing, labor provided by or at the direction of the
Company during the twelve (12) month period from the
date of delivery referred to in the initial paragraph above, in
connection with the Twelve Month Warranty of parts provided
in the initial paragraph above, is included in such warranty,
solely in the case in which a packaged terminal system is sold
by the Company to an Original Owner for use in a new facility
to be constructed and located in the greater New York City
metropolitan area. For the avoidance of doubt, except in the
case described in the preceding sentence, the Company has
no obligation under this warranty to provide for field labor or to
make reimbursement of the labor or services charges of any
other party, provided, however, that the Company, in its sole
and absolute discretion, may elect to do so, so long as (i) such
election is set forth in a writing signed by the Company and (ii)
the facility at which the applicable packaged terminal system
is or will be installed is located in the greater New York City
metropolitan area (the “Metropolitan Area”).
The obligations of the Company set forth in the preceding
paragraphs of this Section are in all cases subject to the
satisfaction of the following conditions: (x) the Company
shall have received proof, satisfactory to the Company, of
the purchase by the Original Owner from the Company of
the packaged terminal system that is the subject of the
Original Owner’s claim, (y) all amounts due and payable to
the Company on or prior to the date of such claim in respect
of such packaged terminal system shall have been paid in full
and (z) nothing shall exist or occur that relieves the Company,
in accordance with the terms of this agreement, from the
performance of its warranty obligations hereunder.

from date of the expiration of the twelve-month Warranty.
Components under this warranty will be supplied at Ice Air’s
expense provided the failed component is returned to Ice Air.
This optional warranty does not include any other parts of the
equipment such as fans, fan motors, controls, cabinet parts,
electrical relays, capacitors, protective devices, or wiring. Ice
Air is not obligated under this warranty for field labor such as
service for inspection, removing, packing, and/or reinstalling
the refrigeration circuit, nor for return transportation charges.
In addition, the Company is not obligated under this warranty
to make reimbursement of the labor or service charges of any
other party. Ice Air reserves the right to make a handling and

lieu of all other warranties. Ice Air is not liable for incidental or
consequential damages, whether the theory is breach of this
or any warranty, negligence, or strict tort. No person (including

The above warranties are void if Ice Air’s equipment has
been damaged, misused, subjected to abnormal use or
service or its serial number has been altered, defaced, or

Important Disclaimers
Ice Air Has No Responsibility For:
(A) Certain Damages
The following are the responsibility of the user. None of the
following constitutes a manufacturing defect, and each is
expressly excluded from the warranty plan:
1) Failure of unit to operate satisfactorily due to improper
amount of air on evaporator coil or air supply to air cooled
condensers.
2) Damage to unit or unsatisfactory operation due to improper
cleaning of evaporator coil or use of unit in corrosive
atmosphere locations such as chemical plants, refineries, or
salt spray areas.
3) Damage to unit from unsatisfactory operation due to blown
fuses, inadequate or interrupted electrical service, use of
improper electrical protective devices or operation of unit
on power supply other than covered by nameplate rating
of unit.
4) Damage due to failure to properly maintain unit.
5) Damage due to transportation or handling prior to and
during installation.
6) Damage due to accident or from alteration, improper
installation or tampering.
7) Failure to clean or replace filter timely.
8) Misapplication of equipment.
9) Damage due to deviation from original design and intended
use of equipment.
10) Damage due to use of additional accessories either
unapproved or approved but modified or manipulated.
(B) Installation
Ice Air is not responsible for the design, execution, and
performance of the installation method or any of the accessory
items used during installation such as seals, caulking,
weatherproofing, supporting structures, attachment means,
louvers and frames supplied by others.
(C) Check, Test and Start
Check, Test and Start of the air conditioners by an experienced
person is the responsibility of the installing contractor. This
consists of physically confronting each conditioner operating
in both heating and cooling modes and correcting any minor
deficiencies noted. After the equipment leaves the factory, it
may become damaged or maladjusted during transportation
or on the job. Sometimes wires are disconnected accidentally,
or fan motors move on their bases due to rough handling,
causing fans to strike; a component(s) may be inoperable.
The correction of such conditions is part of the Check, Test
and Start. Note that unless otherwise specifically agreed to
in writing, Ice Air has no obligation to perform, nor does the
price of its equipment include field labor in connection with
the performance of, these Check, Test, and Start procedures
(or the like).
