Gree’s GA aeries PTACs are not individually equipped with a power cord, so one must be ordered separately based on the voltage and amperage of your electrical circuit.
If the unit is to be plugged into a receptacle, then a line cord connection kit needs to be selected. If it will be permanently connected, a hardwire connection must be used.

NEW CONSTRUCTION
RETROFIT/REPLACEMENT
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.
If you are replacing a unit in an existing wall sleeve,
your options include:
• Replace the existing wall sleeve with the
the polymer wall sleeve. See accessory sleeve
section for selecting the correct sleeve for
your application.
NOTE: in most cases, when replacing the
wall sleeve, the exterior grille must also be
replaced.
• Use an existing sleeve and exterior grille. The
Gree GA series PTAC will fit into:
— The following major competitors’ wall
sleeves/grilles: Carrier, GE, Amana,
Trane, Friedrich and Bryant, and NO
accessory retrofit kit is required.
— Friedrich T series and ZoneAire wall
sleeves, with a required wall sleeve
extension (see accessory Friedrich
Retrofit Wall Sleeve Adapter).

Installation instructions are shipped with all PTAC
units. It is important that air conditioning systems be
properly sized and installed for each application in
order to achieve the desired temperature and humidity
levels within the space to be conditioned. It is
strongly recommended that a professional engineer
match the PTAC units with the building structure and
climate.
The following application considerations are all
important in choosing the proper PTAC system for
the building structure.
Condensate Removal
Undersizing
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.: DRAINKIT-4PK) and a building condensate drain
system is recommended.
If a PTAC unit is undersized (cooling capacity is less
than required load for an application), the unit
will not be able to cool the space down to the desired
temperature during very hot days. The result could be
warm and humid or warm and dry conditioned space.
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.
Oversizing
If a PTAC unit is oversized (cooling capacity is
greater than required load for the specific application),
the unit will cool the space down to the desired
desired temperature too quickly.
The unit will cycle on and off, however,
dehumidification only takes place when the unit is
operating. The result of this type of application in a
hot and/or humid climate would be a cool, yet
excessively humid, space.
Air Infiltration
Excessive air infiltration can intensify problems
associated with undersizing 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.

Undersizing
If a PTAC unit is undersized (cooling capacity is less

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

Air Infiltration
Excessive air infiltration can intensify problems
associated with undersizing or oversizing a PTAC

infiltration include vents, gaps around windows and
doors, and improperly sealed floors, ceilings or wall
joints.

Undersizing
If a PTAC unit is undersized (cooling capacity is less
than required load for an application), the unit
will not be able to cool the space down to the desired
temperature during very hot days. The result could be
warm and humid or warm and dry conditioned space.

Air Infiltration
Excessive air infiltration can intensify problems
associated with undersizing 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)

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

If you are replacing a unit in an existing wall sleeve,
your options include:
• Replace the existing wall sleeve with the
the polymer wall sleeve. See accessory sleeve
section for selecting the correct sleeve for
your application.
NOTE: in most cases, when replacing the
wall sleeve, the exterior grille must also be
replaced.
• Use an existing sleeve and exterior grille. The
Gree GA series PTAC will fit into:
— The following major competitors’ wall
sleeves/grilles: Carrier, GE, Amana,
Trane, Friedrich and Bryant, and NO
accessory retrofit kit is required.
— Friedrich T series and ZoneAire wall
sleeves, with a required wall sleeve
extension (see accessory Friedrich

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

greater than required load for the specific application),
the unit will cool the space down to the desired

properly sized and installed for each application in
order to achieve the desired temperature and humidity
levels within the space to be conditioned. It is

B. Operating
Characteristics:
Chassis shall be capable of starting and running at
115˚ F (46.1˚ C) ambient outdoor temperature per
maximum load criteria of ARI Standard 310/380.
C. Electrical:
The accessory power cord or hardwire kit for the
unit will be ordered separately. The power cord
accessory will be 58“ (1473 mm) for 208/230v
models or 15“ (381 mm) for 265v models. The
Hardwire kit accessory will provide 36” (914 mm)
of flexible conduit. The chassis current draw shall
be specified on the chassis nameplate and match
electrical requirements specified on the Contract
drawing schedule and specifications.
The power cord plug configuration shall conform
to NEMA standards and the rating shall support
the current draw of the electric resistance heater.
For 265v installations, UL codes require the use of
an electrical equipped subbase for power cord
usage or hardwire conduit for non--corded
installations.
D. Safeties:
Compressor shall have automatic reset, over
temperature and over current protection. The fan
motors shall have an inherent, automatic reset
over temperature protection. The electric heater
shall have two over temperature protectors.
