GA
Whether you are designing a new structure or
replacing packaged terminal air conditioning units in
an existing building, Gree GA Series will meet your
needs.
The Gree GA series Packaged Terminal Air
Conditioning (PTAC) unit is designed to meet the
needs of the architect, engineer, and contractor. For
unit installation, Gree’s expert support network will
assist in all applicable aspects of the construction
project, from preparing a budget to start-up.

APPLICATION CONSIDERATIONS
Installation instructions are shipped with all PTAC
units. It is important that air conditioningsystems be
properly sized and installed for each application in
ordertoachievethedesiredtemperatureandhumidity
levels withinthe space to be conditioned. It is
strongly recommended that a professional engineer
matchthePTAC unitswiththebuilding structureand
climate.
The following application considerations are all
important in choosing the proper PTAC system for
the building structure.
Undersizing
If a PTAC unit is undersized (coolingcapacity is less
than required load for an application), the unit
will not be able to cool the space down to the desired
temperatureduring veryhot days. Theresultcouldbe
warm and humid or warm and dry conditionedspace.
Oversizing
If a PTAC unit is oversized (coolingcapacity is
greater than required load for the specific application),
the unit will cool the space down to the desired
desired temperature tooquickly.
Theunit will cycle on and off, however,
dehumidificationonly takes placewhen theunit is
operating.The result of this type of application in a
hot and/or humid climate would beacool, yet
excessively humid, space.
Air Infiltration
Excessive air infiltrationcanintensify problems
associated withundersizing or oversizing a PTAC
unit. This can be the cause of insufficient cooling,
dehumidification, or heating. Sources of air
infiltration include vents, gaps around windows and
doors, and improperly sealed floors, ceilings or wall
joints.
GA
Condensate Removal
Gree’s GA series has a new condensate (water)
disposal system. The outdoor fan prop has a built in
slinger ring which draws condensate water through a
suction port built into the outdoor coil shroud. The
water passes though the suction port and is sprayed
on the warm outdoor coil for evaporation. Thus
providing better disposal of excess condensate and
improving unit operating efficiency.
It is normal and desirable to have some condensate
water in the ebase pan to boost operating efficiency.
NOTE: This unit will not always evaporate 100%
of the unit generated condensate and blown in
rain water. If it is necessary to control 100% of
the condensate, the Drain Kit (Part No.: DRAIN-
KIT-4PK) and a building condensate drain
system is recommended.

NO--RUST WALL SLEEVE
AND FRONT PANEL
The indoor front panel and polymer wall sleeve use
nonmetallic compoundsthat never rust or corrode, do
not support combustion, and do not give off toxic
fumes. The weather-resistant feature exceeds
requirements of Underwriters Laboratories and resists
damage caused by impact and scratching.
Insulated polymer wall sleeves combine all of the
above features with factory-installed insulation.The
insulation helps to reduce heat loss, save energy,
provide better sound absorption, and reduce the risk
of sleeve sweating.
Grees’s metal wall sleeves are available in a variety
of sizes for moststandard and deep wall applications.
All metal wall sleeves come withfactory-installed
insulation, designed to minimize heatloss and reduce
outdoornoise transmissionsintothe room.

The unique vent system is activated by a two-
position control. Fresh outside air is redirected by
the vent door to the indoor room. A molded plastic
filter prevents dirt and debris from entering the
room side of the unit. The vent mechanism is made
from non corrosive material ensuring reliable
operation. Amagnet on the door and high-pressure
airflow create a tight, draft free seal when the vent
door is closed.

a removable terminal connector to make field wiring
easy. See more info on wall thermostat connections
in the Dimensional Drawings and Installation Data
Section.
Notes:
— Thermostat wire is field supplied and
recommended wire size is 18 to 20 gage
solidthermostat wire.
— Wire should never be routed throughthe

APPLICATION CONSIDERATIONS
Installation instructions are shipped with all PTAC
units. It is important that air conditioningsystems be
properly sized and installed for each application in
ordertoachievethedesiredtemperatureandhumidity
levels withinthe space to be conditioned. It is
strongly recommended that a professional engineer
matchthePTAC unitswiththebuilding structureand
climate.
The following application considerations are all
important in choosing the proper PTAC system for
the building structure.
Undersizing
If a PTAC unit is undersized (coolingcapacity is less
than required load for an application), the unit
will not be able to cool the space down to the desired
temperatureduring veryhot days. Theresultcouldbe
warm and humid or warm and dry conditionedspace.
Oversizing
If a PTAC unit is oversized (coolingcapacity is
greater than required load for the specific application),
the unit will cool the space down to the desired
desired temperature tooquickly.
Theunit will cycle on and off, however,
dehumidificationonly takes placewhen theunit is
operating.The result of this type of application in a
hot and/or humid climate would beacool, yet
excessively humid, space.
Air Infiltration
Excessive air infiltrationcanintensify problems
associated withundersizing or oversizing a PTAC
unit. This can be the cause of insufficient cooling,
dehumidification, or heating. Sources of air
infiltration include vents, gaps around windows and
doors, and improperly sealed floors, ceilings or wall
joints.

Condensate Removal
Gree’s GA series has a new condensate (water)
disposal system. The outdoor fan prop has a built in
slinger ring which draws condensate water through a
suction port built into the outdoor coil shroud. The
water passes though the suction port and is sprayed
on the warm outdoor coil for evaporation. Thus
providing better disposal of excess condensate and
improving unit operating efficiency.
It is normal and desirable to have some condensate
water in the ebase pan to boost operating efficiency.
NOTE: This unit will not always evaporate 100%
of the unit generated condensate and blown in
rain water. If it is necessary to control 100% of
the condensate, the Drain Kit (Part No.: DRAIN-
KIT-4PK) and a building condensate drain
system is recommended.

HEAT PUMPS PAY THEIR
OWN WAY
Heatpump models are available at a nominal
additional cost. In many locales, the payback is
realized in just a few months. Cost and payback
details are provided on the next page.
SPECIAL FEATURES
Two-Stage Thermostat:
The indoor thermostat senses the indoor temperature
and automatically turns on the electric heat to warm
the roomquickly. After the desired temperature
conditions have been satisfied, the thermostat
automatically switches to heatpump mode. If
compressorfailureoccurs,thethermostatwillprovide
backup electric heat automatically.
Outdoor Thermostat:
During the heating cycle, the outdoorthermostat
senses outdoor coil temperature. It switches the unit
to electric heatmodewhen theoutdoor coil
temperature is 28˚F (--2.2˚C) or below for one
minute. Thethermostatswitchestheunitback to heat
pump modewhen theoutdoor coil temperature rises
above40˚F(4.4˚C)fortenminutes,which is enough
to provide heat to meet demand.The entireoperation
is completely automatic.
Reversing Valve:
The reversing valve provides quiet refrigerant flow
when energized in heating mode. The valve controls
the direction of refrigerant flow for both heating and
cooling functions and remains energized as long as
the controls are in the heatposition. When the
cooling controls are activated, the valve automatically
reverses to the cooling position.

FIELD--INSTALLEDACCESSORIES
WALL SLEEVES
Important Sleeve Installation Considerations:
•All Gree sleeves are self pitching and must
be mounted level in all directions.
•Thesleeve should be caulked on all sides,
includingboth inside and outsidethe
building.
•If more than4in. (101.6 mm) of wall sleeve
projects into the room, an accessory subbase
must be used for support.
•For all applications with an accessory
subbase, wall sleeve must extend 3--1/4 in.
(82.6 mm)minimum into room and must be
3--1/4 in. (82.6 mm)minimum to 5--1/2 in.
(139.7 mm) maximum above floor (including
carpeting) to allow for proper fit of subbase.
•For applications where the wall sleeve is
mounted flush to the exterior of the
building (or recessed in), Gree recommends
a field--supplied drip edge be installed to
prevent water infiltration into the building.
•Insulated wall sleeves should be considered
for superior sound absorption, to reduce heat
loss and to prevent sleeve sweating, a
condition that can occur when the outside
temperature is cold and the indoor conditions
are warm and humid.
Polymer Wall Sleeves
Chooseapolymer wall sleeve for maximum
protection and appearance.
All polymer wall sleeves are made from a molded
polymer that is designed for strength and durability.
This material has excellent corrosion resistance and a
flammability rating of UL94--5V.
The sleeve surface is textured to prevent shine and
hide scratches. The rib configuration on the sleeve
bottom allowseasy chassis removal and aids in
drainage. The locatingholes in theside and top
panels allow for easy fastening of thesleeve to wall
Insulated Polymer Wall Sleeve

Part No.: SLEEVE–MOLDING
For a superior look and to hide any construction
imperfections, use Gree’s wall sleeve molding kit to
trim the wall sleeve to the wall. The molding kit is a
perfect solution and can be used with any Gree wall
sleeve (matches wall sleeve color).
The Friedrich (and ZoneAire) wall sleeve adapter is
constructed of metal and is designed to increase the
depthofanexistingFriedrichT-seriesorZoneAirewall
sleeve to accommodate all industry standard PTAC
units.

APPLICATION CONSIDERATIONS
Installation instructions are shipped with all PTAC
units. It is important that air conditioningsystems be
properly sized and installed for each application in
ordertoachievethedesiredtemperatureandhumidity
levels withinthe space to be conditioned. It is
strongly recommended that a professional engineer
matchthePTAC unitswiththebuilding structureand
climate.
The following application considerations are all
important in choosing the proper PTAC system for
the building structure.
Undersizing
If a PTAC unit is undersized (coolingcapacity is less
than required load for an application), the unit
will not be able to cool the space down to the desired
temperatureduring veryhot days. Theresultcouldbe
warm and humid or warm and dry conditionedspace.
Oversizing
If a PTAC unit is oversized (coolingcapacity is
greater than required load for the specific application),
the unit will cool the space down to the desired
desired temperature tooquickly.
Theunit will cycle on and off, however,
dehumidificationonly takes placewhen theunit is
operating.The result of this type of application in a
hot and/or humid climate would beacool, yet
excessively humid, space.
Air Infiltration
Excessive air infiltrationcanintensify problems
associated withundersizing or oversizing a PTAC
unit. This can be the cause of insufficient cooling,
dehumidification, or heating. Sources of air
infiltration include vents, gaps around windows and
doors, and improperly sealed floors, ceilings or wall
joints.
GA
Condensate Removal
Gree’s GA series has a new condensate (water)
disposal system. The outdoor fan prop has a built in
slinger ring which draws condensate water through a
suction port built into the outdoor coil shroud. The
water passes though the suction port and is sprayed
on the warm outdoor coil for evaporation. Thus
providing better disposal of excess condensate and
improving unit operating efficiency.
It is normal and desirable to have some condensate
water in the ebase pan to boost operating efficiency.
NOTE: This unit will not always evaporate 100%
of the unit generated condensate and blown in
rain water. If it is necessary to control 100% of
the condensate, the Drain Kit (Part No.: DRAIN-
KIT-4PK) and a building condensate drain
system is recommended.

OUTDOOR GRILLE SELECTION
IMPORTANT: If you wish to use a grille not made
for the Gree GA series contact Gree Application
Engineering.
The followingguidelines must be followed in the
initial selection of any alternate exterior grille or
louver:
1. The louver must haveaminimum of 65% free
area. Free area is the minimum area of the
opening in an air inlet or outlet in which air can
pass. Free Area(%) = X/Y.
2. The louver should be attached to the wall sleeve
in a manner that will prevent recirculation of
condenser discharge air into the inlet. In most
applications, baffles, splitters, and/or gasket
will be required betweenthe chassis tube end
sheets and the louver to prevent air
recirculation.
The above criteria must be followed, since a louver
that is restrictive or allows re--circulation will result
in a reduction of the unit’s capacity and efficiency
and will ultimately shorten the compressorlife.
