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
case 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 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 inter-
changeable with units no longer available from the original manufacturer.
Our units are engineered to t perfectly within the existing wall case, thereby
reducing installation time and expense. ey are manufactured at our mod-
ern 75,000 square foot plant on Long Island in New York.
ank you for considering our products,
e Islandaire Team

Applications
e EZ Series 42 and DR units are designed and manu-
factured for new construction or the replacement of
packaged terminal air conditioning (PTAC) units in an
existing building. Our packaged terminal air condition-
ing (PTAC) units provide year-round comfort control for
hotels, motels, apartments, dormitories, shops, nurs-
ing homes, assisted living centers, satellite oces, room
additions and other applications that require economical
heating and cooling.
e product is designed for individually-zoned, comfort-
controlled, heating and cooling. e unit width is an
industry standard 42”. We oer our cooling chassis to
operate with cooling only or electric heat. e design
standards, heavy duty construction and the focus on
indoor noise reduction has created our unit as the pre-
mier unit of the future. Individually 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 oper-
ating economy.
ermostat and fan controls are built into the digital
touch-pad, plus all units have the exibility to convert
to a 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 EZ42 and EZDR Packaged Terminal Air
Conditioning (PTAC) unit is designed to meet the needs
of the architect, engineer, and contractor. For unit instal-
lation, Islandaire’s expert support network will assist in
all applicable aspects of the construction project, from
preparing a budget to start-up.
ADVANTAGES FOR NEW CONSTRUCTION
Design Flexibility For e Architect Engineer
•Super-quiet performance, indoors and out
•No bulky duct system
•No separate equipment room
•No water towers or additional cooling equipment
•Less sensitivity or building orientation
•Optional architectural grille to permit custom
exterior appearance
LOWER OPERATING COSTS & RELIABLE COMFORT FOR THE
OCCUPANT
Islandaire helps lower utility costs with energy ecient
units that exceed industry standards. Energy savings
are achieved in both heating and cooling environments
through ecient mechanical design and onboard elec-
tronic logic. Separate indoor and outdoor fans provide
lower operating costs. Energy management soware 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 slide-out chassis eases installation into the wall
sleeve. Rapid servicing reduces downtime: complete
chassis can be replaced in minutes without disrupting
other occupants.

Applications (cont.)
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
units 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 temperature
during very hot days.
OVERSIZING
If a PTAC unit is oversized (cooling capacity is greater
than required capacity for the specic 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 inltration can intensify problems associ-
ated with undersizing or oversizing a PTAC unit. is
can be the cause of insucient cooling, dehumidica-
tion, or heating. Sources of air inltration include vents,
gaps around windows and doors, and improperly sealed
oors, ceiling or wall joints.
Guaranteed Quality
Each Islandaire unit is designed to operate quietly and
eciently and is backed by the best warranty program
available. Standard warranty is 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 con-
struction project, Islandaire is the smart choice for all
your air conditioning and heating needs.
Indoor Air Quality - DR.
PTAC (EZDR Series Units
Only)
In addition to an already quiet unit, we have
co-developed an indoor air quality option called
Dr.PTAC.
Dr.PTAC is currently designed as a two-stage system.
e primary stage conditions room air and tempers
the air to acceptable air quality levels. e secondary
stage brings in conditioned outside air at a rate of up
to 55 CFM, to compensate for toilet exhaust and room
occupancy, and continuously pressurizes the room. e
secondary stage is initiated by an outdoor humidistat that
allows the unit to condition the incoming fresh air about
50% RH. e system can be calibrated to run at higher
outdoor RH levels, but the recommended maximum set
point 50% outdoor RH. When outdoor RH levels are
above the set point, the secondary compressor is initiated
and conditions make up air below the set point.
e secondary fan continuously runs allowing fresh, con-
ditioned, make-up air at a rate of up to 55 CFM (leaving
coil CFM) to enter the room. e unit is manufactured
in accordance to ARI, UL, CSA standards for the primary
side and AHAM and UL standards for the secondary
side.

Product Overview
Quiet Operation
e cross-ow tangential fan wheel design used in our
EZ42 and EZDR units provide whisper quiet operation
while delivering maximum airow 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.
Durable Construction
•Islandaire PTAC/PTHP units are built with
durable, quality components designed for continu-
ous operation in all environments.
•Our wall sleeves are constructed of thick 18-gauge
steel with a tough baked-on nish for maximum
durability.
•e outdoor fan motor is totally enclosed, prevent-
ing damage from moisture and debris introduced
by extreme weather conditions. Both indoor and
outdoor fan motors are permanently lubricated for
extended life.
•Electrical components are located on the indoor
side of the wall protecting them from driving rain
and humidity.
•e compressor is a reliable, high eciency design
rotary compressor. It is hermetically sealed and
designed for continuous operation.
•Repositionable discharge grille allows angle of air-
ow to be adjusted according to application. Made
from tough plastic material that won’t rust, resists
scratches and is easy to clean.
Seacoast Construction
Application of air conditioning equipment in a corrosive
environment requires special consideration. e cor-
rosive nature of salt water vapor, chlorine and acid vapor,
demands a unit that can withstand these environments.
Any metal portion that is exposed to a corrosive vapor
must be specially treated.
All Islandaire PTAC units have special corrosion protec-
tion that can help dramatically extend the life of the unit.
Listed below are just some of the components that feature
corrosion protections:
•
Wall Sleeve – e entire wall sleeve is con-
structed of 18-gauge steel. Treated inside and
outside with a baked-on based powder coat paint
to protect it from the corrosive eects of salt spray.
•
Base Pan – Base pan has a corrosion resistant
coating to protect it from the elements.
•
Condenser Coil – Protective coating applied to
the coil to prevent corrosion and weathering.
•
Condenser Fan Blade – Constructed of strong
engineering plastic that has excellent ame resis-
tance and dimensional stability over a wide range
of service temperatures.
•
Condenser Fan Motor – Specially coated by the
manufacturer.
•
Compressor – Protective coating applied by the
manufacturer on the exterior to enhance equip-
ment life and performance.
•
Outdoor Louver – Made of aluminum, etched
and anodized for maximum corrosion protection.
Available in stamped or architectural styles. Can
be painted in a wide choice of colors.
Standard on All Models:
Corrosion protection treatment shields the EZGS
unit from corrosive environments and extends
the life of the unit, especially in coastal locations.

Dr.PTAC information
e Dr. PTAC system is an add on system to our standard PTAC unit to provide conditioned makeup air into a space thru
the PTAC unit by providing up to 55 CFM of outdoor air 24/7 by forced fan and cycling dehumidier compressor based on
outdoor relative humidity levels.
Dr. PTAC was created to solve issues with dehumidication in rooms and to introduce fresh air due to deciencies of
oxygen levels. Dr. PTAC is not only a PTAC but a Conditioned Make Up Air unit. New ASHRAE studies show that many
illnesses in hotel rooms can be attributed to oxygen decient atmospheres. Dr. PTAC solves that issue by introducing tem-
pered conditioned make up air that satises both humidity level introduction and supplied oxygen.
Dr. PTAC 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 primarily a dehumidica-
tion unit that provides up to 55 CFM of outside fresh air into the room. e correction of the Sensible Temperature comes
from the main PTAC unit, which provides additional dehumidication with temperature correction. Overall unit e-
ciency over standard PTAC’s is approximately 3% improvement. e compressor/dehumidication process is controlled by
a humidistat (factory set at 50% RH), which is monitoring the outdoor relative humidity level and is adjustable by a quali-
ed servicer. When the outdoor humidity level raises above 50% RH, the compressor and dehumidication process starts.
Below 50% RH, compressor operation and dehumidication is stopped, however, fan operation continues to provide up to
55 CFM of outdoor air into the space.
e dehumidication system has a temperature switch which is monitoring both the refrigeration and the outdoor air
temperatures. If the outdoor air goes 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 climates is required. Condensate from
the dehumidier drains into the PTAC drain pan, where it is also 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 is piped to a drainage system via an optional drain kit.
ADVANTAGES OF THE DR. PTAC SYSTEM:
1. Lower installation/renovation costs than typical DOAS*
2. Decrease inconvenience to customer due to construction/installation of a DOAS* system
3. More humidity control in a room over use of a simple PTAC 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

•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 mea-
sure a minimum of 16 ½” high x 42 ½” wide.
•If opening will start right at the nished oor level,
leave enough clearance for carpeting, etc. If using
a power cord, leave enough space for the cord to
exit from under the front panel.
•When a subbase is used, the opening must start
above the nished oor to match the height of the
subbase selected.
•When construction is complete, check the wall
opening to be sure the wall sleeve will slide into the
opening without obstruction.
•If installed in a concrete or masonry wall, a lintel
must be provided in the wall opening for support.
•Do not use the wall sleeve as a lintel.
•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.
DO NOT SLOPE THE WALL SLEEVE
TOWARD THE ROOM.
•e installer must provide adequate sealing and
insulation around the sleeve aer it is installed.
•If used, a 208/230 volt wall receptacle must be
located within 58 inches of the lower right sleeve
corner. Extension cords must not be used with the
unit.
•For installations in walls deeper than 13-7/8
inches, special care is necessary to prevent prob-
lems with rain water, condensate drainage and
intake/discharge air. Consult with your Sales Rep-
resentative before attempting such installations.

Wall Sleeve Installation Instructions (cont.)
Wall Sleeve Installation
Aer the wall opening is checked for location, size, and
clearances, proceed to wall sleeve installation.
1. Install Condensate Drain Kit (if applicable).
2. Slide the wall sleeve into the wall opening. e unit
chassis must t snugly and uniformly into the wall
sleeve without distortion.
3. Make sure the sleeve is within the range of minimum
projections as outlined on the next page.
4. Level wall sleeve side-to-side. When using an
INTERNAL DRAIN with this unit, it is recom-
mended to install the wall sleeve in a level position
front-to-back within the wall. If the internal drain
was to clog up from lack of maintenance, water will
still overow through the weep slots in the sleeve
near the louver and be directed outdoors. For proper
drainage, the sleeve should be level from side-to-side
and one-quarter bubble in the sight glass sloping to
the outside (if unit is to drain outside).
5. Secure the wall sleeve by anchoring with fasteners
through the sides and top. Drill holes of proper size
and in the proper location so the screws will engage
into strong supporting members of the wall. DO
NOT DRILL THROUGH BOTTOM OF WALL
SLEEVE. THIS CAN CAUSE LEAKAGE OF CON-
DENSATE WATER WITHIN THE WALLS.
6. Check the level of the wall sleeve and adjust if neces-
sar y.
7. Caulk or seal around the outside of the entire
sleeve.
8. Recycle or dispose of packaging materials per local
codes.
Note
e installer must determine and supply the
mounting 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.

Condensate Drain Kit
Condensate Drain Kit
Part Number 4090661
An indoor/outdoor drain kit is available as an accessory
item. When a drain kit is to be installed, do so before
installing the wall sleeve in the wall.
During periods of high humidity and/or during heat
pump operation condensate water will collect in the bot-
tom pan of the chassis. When the chassis bottom pan is
full, the water will overow into the wall sleeve and out
the drainage holes on the back edge of the wall sleeve.
e Condensate Drain kit contains an overow tube to
direct excess condensate water from the bottom of the
sleeve to either an internal or external drainage path.
Because heat pumps generate condensate even during
the heating season, it is recommended to always use a
drain kit with heat pump models. Determine whether
the kit should be installed as an internal or external drain
system.
External Drain
Installation
Part Number 6140165
e drain kit can be installed as an external drain on the
le or right side drain opening on the sleeve. Determine
which drain opening will provide the best drainage for
the installation.
Local codes will determine the proper method for con-
densate disposal. e drain kit must be installed before
installation of the wall sleeve condenser grille.
1.
Remove the cardboard weather board from the
wall sleeve.
2. Install the outdoor drain tting and one of the
outdoor drain tting gaskets over one of the
drain holes on the rear of the wall sleeve. Secure
this assembly to the rear of the sleeve with two
sheet metal screws into the holes provided in the
wall sleeve.
3. Cover and seal the remaining drain hole using
the remaining outdoor drain gasket, cover plate
and remaining sheet metal screws provided.
Periodically inspect drain passages for blockage. Blow
out drain tubing annually to prevent overow from
entering the building.
NOTE
is drain kit serves only as a link between the
unit and eld-supplied condensate drain system.
Installing the kit without connecting it to
a drainage system will result in inadequate
condensate removal, possible leakage and
corrosion.

Internal Drain
Installation
Part Number 6140165
e drain kit can be installed as an internal drain on the bot-
tom of the wall sleeve to allow condensate to drain into an
internal drain system inside of the building. Locate the drain
so that it will be on the room side of the wall when the cabinet
wall sleeve is installed.
NOTE: e drain kit must be installed prior to the installation
of the wall sleeve.
1.
Locate an area on the wall sleeve that will be inside
the room when the sleeve is installed. If a subbase
is installed, locate the kit a minimum of 5 ½” from
the front ange of the wall sleeve. is clearance will
provide adequate clearance for the subbase.
2. Cutout the template shown to the right. Using this
template, locate and drill the drain kit holes as close
to the outside wall as possible.
3. Using detail gure 13 as a guide, assemble the drain
gasket, drain tting plate, and indoor drain tting
together. Install the assembly into the drilled holes
and secure using the two indoor mounting screws
provided. e screws must be inserted INSIDE the
wall sleeve and TOP driven down into the drain t-
ting plate.
Ensure drain tube is not restricted. Cover the two screw heads
with a good quality outdoor caulking (not supplied) for addi-
tional corrosion protection.
NOTE: If the drain tting is not connected to an indoor
drainage system immediately aer the wall sleeve is installed,
plug the hole with cork (not included) to prevent indoor water
damage in case it rains.
4.
Install a ½” ID tube or hose (not included) on the
drain tting and interconnect it to the drain system
inside of the building. Ensure that there are no kinks
or traps in tube or hose. Kinks or traps can cause
improper drainage.
5. Install the two drain block-o plates and outdoor
drain gaskets on the outdoor portion of the wall
sleeve as shown in gure 15. ese components can
be installed aer the sleeve is secured in the wall
opening just prior to the installation of the condenser

Information for Heat Pump units
Heat pump models oer substantial savings over models
with conventional electric resistance heaters.
Islandaire’s PTAC units provide indoor comfort in the
same manner as conventional air conditioners, removing
heat and humidity from indoor air. e heat and humid-
ity is released to the outdoors. Islandaire’s high eciency
design saves energy and reduces cooling costs.
When the outdoor coil temperature is above 20 °F
(approximately 35 °F outdoor-air temperature), the heat
pump draws heat from outdoor air and uses it to heat
indoor air. Since heat is transferred and not produced,
the heat pump uses less electricity and reduces energy
costs signicantly.
If the outdoor coil temperature falls below 20 °F (approx-
imately 35 °F outdoor-air temperature), the unit auto-
matically switches on a built-in electric heater. e com-
pressor stops and a blower circulates warm air produced
by the heater. When the outdoor coil temperature rises
above 40 °F, heat pump operation resumes automatically.
Heat Pump Features
OUTDOOR THERMOSTAT:
During the heating cycle, the outdoor thermostat senses
outdoor coil temperature. It switches the unit to electric
heat mode when the outdoor coil temperature is 20 °F or
below (approximately 35 °F outdoor-air temperature).
e thermostat switches the unit back to heat pump
mode when the outdoor coil temperature rises above 40
°F, which is enough to provide heat to meet demand. e
entire operation is completely automatic.
REVERSING VALVE:
e reversing valve controls the direction of refrigerant ow
for both heating and cooling functions and remains ener-
gized as long as the controls are in the heat position. 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.

Operating Guidelines
•Do not block airow. Ecient operation of the
unit depends on free circulation of air.
•Paper, leaves, and other debris can reduce e-
ciency and cause serious damage to the compres-
sor.
•Ensure that objects such as drapes, furniture, or
plants are not blocking 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 unit during construction. Con-
struction dust can clog lter and cause permanent
damage to other components.

Remote Thermostats
Remote Thermostat
Control
e PTAC unit can be controlled by any remote elec-
tronic thermostat that can interface with RCBWYG ter-
minals. A wiring harness is provided with conductors for
all applications (Heat Cool, Heat Pump, Multispeed Fan,
etc.). See details on the next page. e Control Selection
jumper must be in T’STAT position. During a call, the
remote thermostat will pass R back to the controller on
a respective terminal. e push buttons on the touchpad
become inactive in the remote thermostat mode.
Note: In terms of outputs, there are two types of thermo-
stats: Relay Contacts and Solid State.
Manufacturers of solid state output thermostats include
loading resistors in their installation kits. ese 560
Ohm, 3W resistors are designed to load thermostat solid
state outputs in order for the output voltage to be either
0 or 24 Vac (i.e., no oating voltage). ese resistors are
connected from W, Y, G to common (C), respectively.
You can wire any type of 24 Vac thermostat straight into
the Remote ermostat Interface on the PTAC control
board (see page 40).
Wireless Wall
Thermostat
Wireless wall thermostats are designed to provide precise
temperature control without the installation labor and
expense of wiring.
•Powered by AA batteries
•Mounts in any suitable location that will provide
an accurate room temperature reading.
•Large LCD display provides the user with current
room temperature, set point temperature, time,
program interval, and other system status informa-
tion.
REMOTE CONTROL NODE
Used with a wireless wall thermostat, the RCN commu-
nicates with the thermostat using unlicensed 900 MHz,
radio frequency energy.
Energy Saving Options
Automatic Change-Over Remote Mounted ermostats
can be obtained to switch from heating to cooling and
from cooling to heating automatically. With automatic
change over, the operation of the heating cycle or the
cooling cycle is determined by the temperature require-
ment of the space.
Most thermostats with this feature are set to change over
when the room temperature varies 3-½ °F from the set-
point. e unit is placed in cooling mode when the set-
point is over 3-½ °F; 3-½ °F under the set point places
the unit in the heating mode. is
3-½ °F variation is usually adjustable from a ½ °F dead
band to a 5 °F dead band. Each cycle is run until the
set point temperature is reached, then that cycle is de-
energized. On some thermostats, the automatic change
over function can be overridden manually by moving the
thermostat selector switch to “heat” or to “cool.”
Fan operation with an automatic change over thermostat
is controlled by the fan selector switch. When placed in
the “fan” mode, the fan runs continuously. When placed
in the “auto” mode, the fan will only energize when the
thermostat calls for heating or cooling.

G. Protection Circuits:
Compressor shall have automatic reset, over tempera-
ture and over current protection. e fan motor shall
have an inherent, automatic reset over temperature
protection. e electric heater shall have two over
temperature protectors.
4.0.1 HEAT PUMP OPERATION
Heat pump units shall have the selected room tempera-
ture maintained by cycling either in the heat pump mode
or electric strip heat. A heat pump unit with electric heat
is switched from the heat pump mode to electric strip
heat when the outdoor coil temperature is 20 °F or when
the heat pump cannot keep up with the heating load and
a two-stage thermostat is used.
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** termi-
nal, or else energize the B** terminal continuously when
in the “auto” position.
4.0.2 ELECTRIC HEAT OVERRIDE
For heat pump applications, electric heat comes on only
when the outdoor coil temperature is below
28 °F, maximizing the amount of time the unit operates
in the more ecient heat pump mode. e minimum
COP for heat pumps, at 47 °F DB outdoor, must be 2.9
for all sizes.
(Heat pump models shall also include reversing valve).
4.0.3 REVERSE CYCLE
A Heat Pump WITH back-up electric heat –
e reversing valve, the compressor, the outdoor con-
denser fan motor and the indoor fan motor shall be
energized. Reverse cycle heating shall occur when the
outdoor coil temperature is
28 °F and above. If outdoor coil temperature drops
below 28 °F or the Outdoor air temperature drops to
35 °F or less, electric heat is the only source of heat.
When the outdoor coil temperature rises back to 40 °F
or above, the Compressor or electric heater is used.
A temperature-sensing device shall be used to moni-
tor the outdoor coil temperature to limit frost buildup.
Defrosting of the outdoor coil will be activated when
outdoor coil temperature drops below 28 °F or out-
door air temperature drops to 35 °F or less. Defrost-
ing is terminated when outdoor coil temperature rises
back to
40 °F. During defrosting, both compressor and the
outdoor fan are turned o. e indoor fan will run at
its set speed.
Condensation accumulated during reverse cycle heat-
ing must 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 a (external/internal) drain system as shown
on plans.

B. Heat Pump WITHOUT back-up electric heat
e reversing valve, the compressor, the outdoor con-
denser fan motor and the indoor fan motor shall be
energized. Reverse cycle heating shall occur when the
outdoor temperatures are 35 °F and above.
If outdoor coil temperature drops below 28 °F or
the outdoor air temperature drops to 35 °F or less,
the compressor stops and there is no source of heat.
When the outdoor coil temperature rises back to
40 °F or above, the compressor reverse cycle is the
heat source.
A temperature-sensing device shall be used to moni-
tor the outdoor coil temperature to limit frost buildup.
Defrosting of the outdoor coil will be activated when
outdoor coil temperature drops below 28 °F of out-
door air temperature drops to 35 °F or less. Defrost-
ing is terminated when outdoor coil temperature rises
back to 40 °F. During defrosting, both compressor
and the outdoor fan are turned o.
e indoor fan will stop if indoor coil temperature
falls below 78 °F. It will restart at its set speed when
indoor coil temperature rises back to 80 °F.
