Our Company
Islandaire is the fastest growing specialty air conditioning and heating
manufacturer in the country. Founded in 1992 by Robert Hansen, it has grown
into a multi-million dollar company in just a few short years. Islandaire builds a
full complement of high quality thru-the-wall replacement air conditioners and
heat pumps, water source heat pumps, and gas units in St. James, New York. Each
model ts perfectly into the existing original wall sleeve assembly, thereby saving
both time and money during installations.
Our Engineering, Production, Sales and Customer Service departments have
been fully integrated to provide the maximum degree of user satisfaction. We
at Islandaire feel that this team approach to manufacturing produces a superior
overall product and assures a larger degree of exibility in design and production
scheduling to meet tight prototyping or construction timetables.
The Perfect Fit
ru-wall air conditioners were developed in the late 1950’s. Over the next
forty years many companies engineered, manufactured and installed a variety
of dierent units throughout the United States and Canada. Today, a number
of these companies are no longer in business or have discontinued their line of
thru-wall air conditioners and no longer carry replacement parts.
Islandaire oers replacement air conditioners and heat pumps that are
interchangeable with units no longer available from the original manufacturer.
Our units are engineered to t perfectly within the existing wall sleeve, thereby
reducing installation time and expense. ey are manufactured at our modern
75,000 square foot plant on Long Island in New York.
ank you for considering our products,
e Islandaire Team

Applications
Islandaire EZ Series GS is a replacement for the Subur-
ban Dynaline units. Our commercial duty construction
with heavy gauge galvanized steel and superior compo-
nents create an ecient reliable unit. is design elimi-
nates the need for any interior or exterior renovation.
Use of the existing wall sleeve and louver saves time and
money, two very important factors in today’s competitive
environment! If the need does occur where the duct
kit, sub-base/skirt, wall sleeve and/or louver needs to be
replaced, we manufacture these accessories as well. is
unit is also used extensively for new construction proj-
ects, throughout the US and Canada.
e product is designed for individually-zoned, comfort-
controlled heating and cooling. e unit width is an
industry standard 42”. e design standards, heavy-duty
construction and the focus on indoor noise reduction has
created our unit as the premier unit of the future. Indi-
vidually controlled PTAC units are ideal for rooms that
are not occupied during vacancies, holidays, weekends
or nights. Individual units allow tenants to choose the
degree of comfort and operating economy.
ermostat and fan controls are built into the digital
touch pad, plus all units have the exibility to convert
to wall thermostat control, or interface into energy
management systems. Whether you are designing a new
structure or replacing PTAC units in an existing build-
ing, Islandaire will meet your needs.
New Construction
e Islandaire EZGS Packaged Terminal Air Condition-
ing (PTAC) unit is designed to meet the needs of the
architect, engineer, and contractor. For unit installation,
Islandaire’s expert support network will assist in all appli-
cable aspects of the construction project, from preparing
a budget to start-up.
Design Flexibility for theArchitect / Engineer
• Super-quiet performance, indoors and out
• No bulky duct system
• No separate equipment room
• No water towers or additional cooling equipment
• Less sensitivity to building orientation
• Optional architectural grille to permit custom exte-
rior appearance
• Integral CO detector alarm available
Lower Operating Costs & Reliable Comfort for
the Occupant
Islandaire helps lower utility costs with energy ecient
units that exceed industry standards. Energy savings
are achieved in both heating and cooling environments
through ecient mechanical design and onboard elec-
tronic logic. Separate indoor and outdoor fans provide
lower operating costs. Energy management soware is
built into the unit’s standard digital controls.
ese units may also qualify for electrical power com-
pany rebates. (Consult your local utility provider for
rebate opportunities.)
Retrofit/Replacement
Islandaire PTAC units are engineered to t perfectly
within most existing wall sleeves, thereby reducing
installation time and expense. ere is no time wasted
on redesigning an existing wall opening or removing an
old wall sleeve. Just slide the old chassis out and replace
with a new one from Islandaire.
EZ Quick connections to the control box simplify electri-
cal hook-up, and our slide-out chassis eases installation
into the wall sleeve. Rapid servicing reduces downtime;
the complete chassis can be replaced in minutes without
disrupting other occupants.

Applications (cont.)
Economical Gas Heat
Islandaire EZGS PTAC units provide high-eciency gas
heat. Gas-heated air is much warmer than conventional
heat pump units, allowing the unit to reach set tempera-
ture levels much faster. e compressor operates only
during the cooling cycle, reducing noise and extending
the life of the compressor.
Guaranteed Quality
Each Islandaire unit is designed to operate quietly and
eciently and is backed by the best warranty program
available. Our standard warranty is for one year parts
and labor, including a ve year compressor part only
warranty and a lifetime warranty on the heat exchanger
part only OR a two year parts only warranty, including
a ve year compressor part only warranty and a lifetime
warranty on the heat exchanger part only.
Whether it is an exact replacement unit or a new con-
struction project, Islandaire is the smart choice for all
your air conditioning and heating needs.
Application
Considerations
It is important for air conditioning systems to be prop-
erly sized for each application in order to achieve desired
temperature and humidity levels. It is strongly recom-
mended that a professional engineer match the PTAC
unit with the building structure and climate.
e following application considerations are all impor-
tant in choosing the proper PTAC system for the build-
ing structure.
UNDERSIZING
If a PTAC unit is undersized (cooling capacity is less
than required capacity for an application), the unit will
not be able to cool the space down to the desired tem-
perature during very hot days.
OVERSIZING
If a PTAC unit is oversized (cooling capacity is greater
than required capacity for the specic application), the
unit will cool the space down to the desired temperature
too quickly creating a cool, yet excessively humid space.
AIR INFILTRATION
Excessive air inltration can intensify problems associ-
ated with under-sizing or over-sizing a PTAC unit. is
can be the cause of insucient cooling, dehumidica-
tion, or heating. Sources of air inltration include vents,
gaps around windows and doors, and improperly sealed
oors, ceiling or wall joints.

Product Overview (EZGS)
Quiet Operation
e dual wheeled fan deck assembly used in our EZGS
units provides whisper quiet operation while delivering
maximum airow required for proper air circulation.
Separate indoor and outdoor fan motors further reduce
operating sound levels and costs.
e heavy gauge construction of the chassis and cabinet
minimizes vibration for quieter operation. Vibration iso-
lators on the rotary compressor keep it running smoothly
and quietly. e unit bulkhead is fully insulated to
decrease outdoor sound transmission.
e compressor is isolated to minimize vibration and
sound transmission for quiet operation.
Safety
e EZGS unit employs a solid-state, electronic, hot sur-
face ignition (HSI) with no open ame. is eliminates
the need for pilot lights. HSI increases energy eciency
while ensuring safety.

Installation Instructions
Unit Specifications
is appliance is intended for new construction or retrot
replacement of most 42” x 16” Package Terminal Air Con-
ditioners. Conrm the electrical rating of this appliance
matches the electrical supply available before beginning
installation (refer to table on page 11).
e eciency rating of this appliance is a product of
thermal eciency rating determined under continuous
operating conditions and is determined independently of
any installed system.
Due to high temperatures, the appliance should be located
out of trac and away from furniture and drapes. Chil-
dren and adults should be alerted to the hazards of high
surface temperatures and should stay away to avoid burns
or clothing ignition. Young children should be carefully
supervised when they are in the same room as the appli-
ance. Clothing or other ammable material should not
be placed on or near the appliance. Any safety screen or
guard removed for service must be replaced before operat-
ing the appliance. More frequent cleaning may be required
due to excessive lint from carpeting, bedding material, etc.
It is imperative that control compartments, burners, and
circulating air passageways of the appliance be kept clean.
Installation and repair should be done by a qualied
service person. e appliance should be inspected
before use and at least annually by a qualied service
person.
Safety Information
A. is appliance does not have a pilot. It is equipped
with an ignition device, which automatically lights
the burner. Do not try to light the burner by hand.
B. BEFORE OPERATING smell all around the appli-
ance area for gas. If your unit uses LP (propane),
be sure to smell next to the oor because LP
(propane) gas is heavier than air and will settle on
the oor.
C. Use only your hand to turn the gas valve knob.
Never use tools. If the knob will not turn by
hand, don’t try to repair it. Call a qualied service
technician. Force or attempted repair may result
in re or explosion.

Wall Sleeve Installation Instructions
Framing
Proper building practices must be used when construct-
ing a wall opening to support a PTAC wall sleeve and
chassis. Units must be installed in accordance with all
applicable codes.
For installation of retrot replacement package termi-
nal air conditioners.
is unit will t most existing 42” x 16” type wall
sleeves by removing the existing front cabinet and air
conditioner. If using the existing wall sleeve and outdoor
louver, they must be inspected to ensure satisfactory con-
dition prior to unit installation, and louver design must
be approved by the Islandaire Engineering Department.
For installation of new construction
A wall sleeve must be installed through a 42-½ inch wide
x 16-½ inch high hole in the exterior building wall. See
Figures 6, 7, and 8 for wall sleeve framing dimensions.
Preparing the Wall
Opening
1. Once a satisfactory location is found and height of
unit is determined, create a wall opening to install
the wall sleeve. e rough opening should measure a
minimum of 16 ½” high x 42 ½” wide.
2. When construction is complete, check the wall open-
ing to be sure the wall sleeve will slide into the open-
ing without obstruction.
3. If installed in a concrete or masonry wall, a lintel must
be provided in the wall opening for support.
4. Do not use the wall sleeve as a lintel.
5. When installed in the opening, the wall sleeve must be
horizontally level from side-to-side and pitched (one
quarter bubble in the sight glass) to the outside if unit
is to drain outside.
6. e installer must determine and supply the mount-
ing bolts and/or screws to attach the wall sleeve to the
sides of the wall opening. Make sure the wall opening
is adequate for strong support.

lation around the sleeve aer it is installed.
8. If used, a wall receptacle must be located within 58
inches of the lower right sleeve corner. Extension
cords must not be used with the unit.
9. For installations in walls deeper than 13-7/8 inches,
special care is necessary to prevent problems with
rain water, condensate drainage and intake/discharge
air. Consult with your Sales Representative before
attempting such installations.
NOTE
Units approved for 0” clearance to combustible
constructions top, sides, and bottom. Front and rear
clearance not applicable as there can be no construction
