Our Company
Islandaire is the fastest growing specialty air conditioning and heat-
ing 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 East Setauket, New York. Each model ts per-
fectly into the existing original wall case assembly, thereby saving both
time and money during installations.
Our Engineering, Production, Sales and Customer Service depart-
ments 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 dierent 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 oers replacement air conditioners and heat pumps that are
interchangeable with units no longer available from the original manu-
facturer. Our units are engineered to t perfectly within the existing
wall case, 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
ADVANTAGES FOR NEW CONSTRUCTION
• Lower Operating Costs and Reliable Comfort
for the Occupant
• Design Flexibility For e Architect/Engineer
• Super-quiet performance, indoors and out
• No bulky duct system needed
• No separate equipment room
• No water towers or additional cooling equip-
ment

exterior appearance
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 ecient mechanical design
and onboard electronic logic. Separate indoor and
outdoor fans provide lower operating costs. Energy
management capability is built into the unit’s stan-
dard digital controls.
ese units may also qualify for electrical power
company rebates. Consult your local utility provider
for rebate opportunities.
Retrofit/
Replacement
Islandaire VTAC units are engineered to t per-
fectly within existing GE wall cases, thereby reduc-
ing installation time and expense. ere is no time
wasted on redesigning an existing wall opening or
removing an old wall case. Just slide the old chassis
out and replace with a new one from Islandaire.
Our EZ Quick slide-out chassis eases installation
into the wall case. Rapid servicing reduces down-
time; the complete chassis can be replaced in min-
utes without disrupting other occupants.
e EZVP and EZVR Series vertical terminal air
conditioning (VTAC) units are designed and manu-
factured for new construction or the replacement of
units in an existing building. Our VTAC units pro-
vide year-round comfort control for hotels, motels,
apartments, dormitories, shops, nursing homes,
assisted living centers, satellite oces, room addi-
tions and other applications that require economical
heating and cooling.
e product is designed for individually-zoned,
comfort-controlled heating and cooling. We oer
our cooling chassis to operate with cooling only or
electric heat. e design standards, heavy duty con-
struction and the focus on indoor noise reduction
has established our product as the premier unit of
the future. Individually controlled VTAC units are
ideal for rooms that are not occupied, such as during
vacancies, holidays, weekends or nights. Individual
units permit tenants to choose their own degree of
comfort and operating economy.
Temperature and fan settings are controlled via wall
thermostat. In addition, all units have the ex-
ibility of working with controls that integrate with
an energy management system. Whether you are
designing a new structure or replacing VTAC units
in an existing building, Islandaire will meet your
needs.
New Construction
e Islandaire VTAC 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 applicable aspects of the construc-
tion project, from preparing a budget to start-up.

Applications (Cont.)
Guaranteed Quality
Each Islandaire unit is designed to operate quietly
and eciently and is backed by the best warranty
program available. Standard warranty is for one
year parts and labor including ve year compressor
part only warranty, or two year parts only including
ve year compressor part only warranty.
Whether it is an exact replacement unit or a new
construction project, Islandaire is the smart choice
for all your air conditioning and heating needs.
Indoor Air Quality -
DR.VTAC
In addition to an already quiet unit, we have
developed an indoor air quality option called the
DR.VTAC.
DR.VTAC is a two-stage system. e primary stage
conditions room air and tempers the air to accept-
able air quality levels. e secondary stage brings in
conditioned outside air at a rate of up to 75 CFM, to
compensate for toilet exhaust and room occupancy,
and continuously pressurizes the room. e sec-
ondary stage is initiated by an outdoor humidistat
that allows the unit to condition the incoming fresh
air to about 55% RH. e system can be calibrated
to run at higher outdoor RH levels, but the recom-
mended maximum set point is 55% outdoor RH.
When outdoor RH levels are above the set point, the
secondary compressor is initiated and conditions
make up air.
e secondary fan continuously runs allowing fresh,
conditioned, make-up air at a rate of up to 75 CFM
(leaving coil CFM) to enter the room. e unit is
manufactured in accordance to AHRI, UL, CSA
standards for the primary side and AHAM and UL
standards for the secondary side.
Application
Considerations
It is important for air conditioning systems to
be properly sized for each application in order to
achieve desired temperature and humidity levels. It
is strongly recommended that a professional engi-
neer match the VTAC units with the building struc-
ture and regional climate.
e following application considerations are all
important in choosing the proper VTAC system for
the building structure.
UNDERSIZING
If a VTAC unit is undersized (cooling capacity is
less than required capacity for the specic applica-
tion), the unit will not be able to cool the space
down to the desired temperature during very hot
days, causing excessive power consumption.
OVERSIZING
If a VTAC unit is oversized (cooling capacity is
greater than required capacity for the specic appli-
cation), the unit will cool the space down to the
desired temperature too quickly, creating a cool yet
excessively humid space.
AIR INFILTRATION
Excessive air inltration can intensify problems
associated with undersizing or oversizing a VTAC
unit. is can be the cause of insucient cooling,
dehumidication, or heating. Sources of air inltra-
tion include vents, gaps around windows and doors,
and improperly sealed oors, ceiling or wall joints.

Product Information
e Dr. VTAC system is an add on system to our standard VTAC unit to provide conditioned make up air into
a space through the VTAC unit by providing up to 75 CFM of outdoor air 24/7 by forced fan and cycling dehu-
midier compressor based on outdoor relative humidity levels.
Dr. VTAC was created to solve issues with dehumidication in rooms and to introduce fresh air due to de-
ciencies of oxygen levels. Dr. VTAC is not only a VTAC, it is also a Conditioned Make Up Air unit. New
ASHRAE studies show that many illnesses in hotel rooms can be attributed to an oxygen-decient atmosphere.
Dr. VTAC solves this issue by introducing conditioned make up air that satises both humidity level introduc-
tion and supplied oxygen.
Dr. VTAC is a two-stage system. e primary unit is responsible for control of Sensible Heat that is introduced
into the room via make up air temperature and thermal load of the occupants. e secondary unit is primar-
ily a dehumidication unit that provides up to 75 CFM of outside fresh air into the room. e correction of
the Sensible Temperature comes from the main VTAC system, which provides additional dehumidication
with temperature correction. Overall unit eciency, as compared with standard VTAC’s, is approximately 3%
improvement. e compressor/dehumidication process is controlled by a humidistat (factory set at 50% RH)
that monitors the outdoor relative humidity level and is adjustable by a qualied service person. Below 50%
RH, compressor operation and dehumidication is stopped. However, fan operation continues to provide up
to 75 CFM of outdoor air into the room.
e dehumidication system has a temperature switch that monitors both the refrigeration and the outdoor air
temperatures. If the outdoor air falls below 38 °F, the compressor is disabled with fan operation continuing to
provide outdoor air into the space. All dehumidier controls and safeties are automatically reset. An optional
air tempering heater is available for the fresh air system for applications where operation in cold winter cli-
mates is required. Condensate from the dehumidier drains into the VTAC drain pan, where it is slung onto
the condenser coil for re-evaporation outside when the A/C runs. Excess condensate is drained into the wall
case which can then either drain to the outside through the louver OR be piped to a eld-supplied drainage
system.
ADVANTAGES OF THE DR. VTAC SYSTEM:
1. Lower installation/renovation costs than typical DOAS*
2. Decrease inconvenience to customer due to construction/installation of a DOAS* system
3. Precise humidity control in a room as compared to a simple VTAC vent or power vent system
4. Allows fresh make up air to travel entirely across sleeping and living areas of a room, exiting through a duct
or under the door.
*DOAS = Dedicated Outdoor Air System

Reversing Valve:
e reversing valve controls the direction of refrigerant
ow for both heating and cooling functions and remains
energized as long as the controls are in the heat posi-
tion. When the cooling controls are activated, the valve
automatically reverses to the cooling position.
NOTE: Be sure to connect reversing valve wiring to
the B (blue wire) connection of the thermostat for heat
pump applications.
Heat Pump Features
Heat pump models oer substantial savings over models
with conventional electric resistance heaters.
When the outdoor coil temperature is above 27 °F
(approximately 35 °F outdoor-air temperature), the heat
pump draws heat from outdoor air and uses it to heat
indoor air. Since the heat supplied to the room is the
result of reversing the refrigeration cycle, the heat pump
uses less power than a conventional heating system,
therefore reducing energy costs.
Outdoor ermostat:
During the heating cycle, the outdoor thermostat senses
outdoor coil temperature. If the outdoor coil tempera-
ture falls below 20 °F (approximately 35 °F outdoor-air
temperature), the unit automatically switches to a backup
electric heater. e compressor stops and a blower circu-
lates warm air produced by the heater.
e thermostat automatically switches the unit back to
heat pump operation when the outdoor coil tempera-
ture rises above 40 °F, which is enough to provide heat
to meet demand. e entire operation is completely
automatic.

Dimensional Drawings
Units must be installed in accordance with all applicable codes. Ensure that there is adequate clearance for ser-
vicing and proper operation. A minimum clearance of 18 inches in front of the air return is required. Provide
additional space for the service technician to work on the unit. Ensure that drapes, beds, bedspreads, furniture,
etc., DO NOT block either the return or discharge air openings.
Your airow should be balanced based on many factors, such as available ESP, room CFM, and ductwork.
Consult an HVAC engineer for proper applications. Higher CFMs tend to increase sensible capacity, enhance
room circulation and increase duct noise, while lower CFMs tend to increase latent capacity and reduce noise.

Installation Instructions - Wall Plenum
Wall Plenum
Since the VTAC unit itself does not install in the wall opening, the use of a wall plenum is necessary to contain
and separate the outdoor air paths to prevent the discharge air from being drawn back into the unit. e ple-
num must be able to hold water in the bottom without leaking into the wall cavity. e installation of ashing,
with a 45° drip-lip, is recommended below the plenum.
e plenum is not load bearing, so a proper header needs to be installed above the plenum just as over any
window opening in the wall. If the building construction is brick, concrete block, or other non self-supporting
material, a lintel must be installed over the plenum opening. e plenum is to be installed square and level
in the opening and secured to the wall construction with screws or nails in the sides located a minimum of 2”
from the bottom of the plenum. No nails or screws may be used in the bottom or top of the plenum to ensure
against water entering the wall cavity. e plenum must be caulked (on all four sides) along the outdoor wall
face and along the interior wall to prevent air inltration and water intrusion.
e wall opening location for the plenum must extend 1” below the top of the Installation Platform. Since the
platform must be a minimum of 8” o the oor, the cutout for the plenum must be a minimum of 7” plus the
thickness of the platform base, o the interior nished oor.
Islandaire oers ve plenums; the choice of the correct plenum is determined by the thickness of the building’s
exterior wall (see below). Each plenum is 19 7/8” wide by 32” high and requires a 20 1/8” wide by 32 1/4” high
cutout in the wall.
Prepare the closet ductwork for later connection to the case. Plenum duct should be insulated to prevent con-
densation and to reduce air noise.

3. If installing the grille from inside the room, use a plas-
tic wire zip-tie or tie a short length of string or insu-
lated wire around several louvers as a holding device
in order to keep a rm grasp on the grille. Angle the
grille through the opening at the rear of the plenum,
then pull the grille back to the plenum and align the
screw heads to the hole. Be sure to keep a rm grip
on the grille to prevent it from dropping and/or caus-
ing possible injury and/or property damage.
4. Secure the grille to the plenum by installing screws
into the plastic fasteners. Be careful not to damage
fasteners by overtightening. Remove the holding
device (plastic wire zip-tie, etc.) when installation is
complete.

Installation Instructions - Base Platform
Base Platform Construction
e VTAC unit requires a eld-supplied base platform (having a load-bearing capacity of 230 lbs. mini-
mum). For warranty purposes, the base platform must be constructed to ensure the unit chassis can be
removed through the access panel. Proceed as follows:
1. Construct a 23 1/4” min. x 23 1/4” min. square platform with legs to raise platform a minimum of 8”
(12” recommended), see diagram above.
2. Make the drain hole cutout(s) as follows
• Primary Drain - Centerline of drain is approximately 4.695” from le platform edge and 8.875”
from back platform edge.
• Secondary Drain - Centerline of drain is approximately 6.625” from le platform edge and 5.625”
from back platform edge.
3. Place the platform in the utility closet large enough to provide the following clearances between it and
the interior surface of the walls/door/panel:
NOTE: When determining the closet depth, consideration must be given to the fact that the ple-
num will protrude into the closet because the plenum will be thicker than the exterior wall.
• If VTAC unit is to be installed through the front of case: 4” minimum clearance from the front of
the platform to inside of the closet door, 3” minimum clearance from each side of the case.
• If VTAC unit is to be installed through the side of case: 5” minimum clearance from the front of the
case, 5” minimum clearance from each side.
4. e platform legs must be positioned so access to the unit drain connections are not blocked. Align
the platform with the opening of the wall plenum and secure to the oor using appropriate brackets
and screws.

1. Remove the front case panel and pull the unit chassis out of the case. Remove
the side panel if a side installation is to be made.
2. Place the empty case onto the base platform in the closet with the outdoor side
facing the wall plenum and slide unit up to plenum.
3. Level the case side-to-side and front-to-back using the four leveling legs.
4. Using the holes in the bottom of the case as guides, drill holes in the mounting
platform. Use four eld-supplied bolts, washers and nuts to secure the case to the platform. Do not
tighten the bolts to the point of distorting the case. Failure to properly secure the case to the platform
may result in excessive unit vibration and increased noise level.
5. Align the case with the plenum opening and attach using six eld-supplied sheet metal screws (stain-
less screws recommended).
6. Slide the unit chassis into the case, either through the front or side panel opening. Push the unit all of
the way into the case until it stops.
NOTE: Either of the case sides may be removed to enable the unit to be slid into the case.

e VTAC unit is equipped with two drain ttings (primary and secondary drains). An external or an
internal drain must be attached to the primary drain connector. e secondary drain is provided for con-
nection when required by state and local codes. Refer to local codes for proper installation of the drains.
External Drain:
Attach a 90° PVC elbow to the unit’s female 3/4” NPT drain connector. Use the other end of the elbow to
run a 3/4” schedule 40 PVC pipe through the knockout hole of the wall plenum to the outside. A notch
must be cut in the rear grille (louver blade) to allow tube to pass through. Seal the gap between the wall
plenum hole and PVC tube.
* Ensure drain lines going out the plenum are sloped downward to allow water to drain out.
e secondary drain hole is shipped open (unplugged) and must either be plugged if not used or con-
nected to an independent drain system. If a secondary drain system is used, attach a 90° schedule 40
PVC elbow to the secondary drain hole directed toward the secondary drain system. If a secondary drain
system is NOT used, install a 3/4” schedule 40 PVC plug to cap the hole. If the secondary drain is not
used, seal its drain port with a 3/4” MNPT plug.

System Controls and Management (Cont.)
Diagnostic Software
e smart logic control performs self-diagnostic tests
that inform service personnel about possible problems.
Error codes are continuously displayed during trouble-
shooting and maintenance until the problem has been
resolved.
Custom Operation
and Continual
Room Temperature
Monitoring
e smart logic control utilizes a built-in sensor for mea-
suring room temperature. When a
pre-determined (user-dened) set point is reached, smart
logic controls automatically adjusts the unit operation to
maintain the room temperature.
Controls Logic
e Islandaire VTAC unit is equipped with an electronic system that runs smart control logic with associated sen-
sors. Built-in safety features protect the unit from the damaging eects of freezing temperatures and power inter-
ruptions. Energy management functionality allows the unit performance to be customized to control its power
consumption. Displaying fault codes help personnel quickly correct any problems if they occur.
Listed below are the built-in automatic features and a brief description of their functions. See Performance Speci-
cations section starting on page 33 for full details of all functions.
Room Freeze
Prevention
e indoor freeze protection monitoring system prevents
unoccupied rooms from reaching freezing levels that can
damage plumbing and xtures. is feature is automatic
regardless of mode and does not require any additional
settings. is feature can be turned on or o by adjusting
DIP switch settings on the main control board.
High Temperature
Compressor
Protection
e life of the compressor is extended through built-in
temperature protection. e system will initiate a com-
pressor lockout if the compressor temperature exceeds
154 °F or if the outdoor air temperature falls below 35 °F.
Low Temperature
Compressor
Protection
An indoor frost sensor will disable the operation of the
compressor if freezing conditions exist. is protects
the compressor from damage due to airow reduction
or low outdoor air temperature. When the coil tempera-
ture rises to a safe temperature the compressor resumes
normal operation.

OPERATING GUIDELINES
• Do not block airow. Ecient operation of the
unit depends on free circulation of air. Paper,
leaves, and other debris can reduce eciency and
cause serious damage to the compressor.
• Ensure that objects such as drapes, furniture, or
plants are not blocking the supply and return
airow.
• Do NOT operate unit with front panel removed or
without lter, as this will void any warranties.
• Keep doors and windows closed. Leaving them
open will increase the workload on the unit and
will result in higher operating cost and excessive
condensate.
Do NOT operate the unit while the building is still
under construction or restoration. Construction dust
can clog the lter and cause permanent damage to other
components.
Freeze Protection Feature
If the temperature in a vacant room falls
below 50°F the freeze prevention thermo-
stat automatically starts the heating cycle to
prevent freezing conditions. All other opera-
tions will be disabled until the temperature
rises above 58°F. When the temperature of the
freeze prevention thermostat rises above 58°F,
the system will resume normal operation.
Heater Safety Feature
When the heater is powered o, fan will
automatically stay on and run for 60 seconds
to ensure the removal of residual heat.
System Controls and Management (Cont.)
Auto Restart Feature
To prevent multiple units from powering up
simultaneously after a power outage, there will
be a random 5 to 15 second delay before the
unit turns on after power has been restored.
Memory Recall Feature
e smart logic control utilizes “non-volatile”
memory; computer memory that can retain
stored information when not powered. is
allows all control settings to be saved and
recalled after a power failure or if power is
disconnected while servicing the unit.
Compressor Short Cycle Protection
Built-in 3 minute timing delay: If cycle is
interrupted, the compressor will not restart for
3 minutes. On all initial power ups there is a
one-time, 3-minute time delay before the unit
will function.

Performance Specifications (Cont.)
4.01 HEAT PUMP OPERATION
Heat pump units shall have the selected room tem-
perature maintained by cycling either in the heat
pump mode or electric heat. A heat pump unit with
electric heat is switched from the heat pump mode
to electric heat when the unit is on and the outdoor
coil temperature reaches 27 °F, or when the outdoor
air temperature is 35 °F and an initial call for heat is
triggered. At this time, back-up electric heat is the
only source of heat, and will only attempt to go back
to normal compressor operation aer it has been
satised.
A temperature-sensing device shall be used to
monitor the outdoor coil temperature to limit frost
buildup. Defrosting of the outdoor coil will be acti-
vated when outdoor coil temperature drops below
27 °F or outdoor air temperature drops to 35 °F or
less.
For heat pump operation, a room thermostat with
a B (heating changeover) terminal is required. is
will mean that some “auto changeover” thermostats
cannot be used, as many of them either do not have
a B terminal, or energize the B terminal continu-
ously when in the “auto” position.
Condensation accumulated during reverse cycle
heating will NOT be evaporated against the indoor
coil so as to prevent contamination of the indoor
air with pollutants and odors. Condensation must
be disposed of using an external or internal drain
system as shown on plans.
The indoor (EVAP.) fan will stop if the indoor coil
temperature falls below 78 °F. It will restart at its
set speed when indoor coil temperature rises back to
80 °F.
3.01 CONTROLS
All standard models shall be equipped with electro-
mechanical controls to simplify the serviceability of
the unit.
A. Standard Control
e chassis shall have a remote thermostat ter-
minal block to enable interface with a modern
remote wall thermostat.
B. Temperature Limiting
All standard models shall have Temperature Lim-
iting functionality built into the system controls.
e temperature limiting function allows a room
temperature setpoint range to be established, to
avoid extreme temperature settings, to maximize
energy savings.
C. Emergency Heat
Emergency Heat Switch (Heat Pump models
only), upon failure of the compressor, shall
automatically disable the compressor in heating
mode and allow the use of electric heat during
heating cycles. e Emergency Heat Switch is
active at all outdoor ambient temperatures.
D. ermostat
e chassis shall come from the factory ready for
wall thermostat installation.
E. Protection Circuits
Compressor shall have automatic reset, over
temperature and over current protection. e
fan motor shall have an inherent, automatic reset
over temperature protection. e electric heater
