WALL THERMOSTAT INTERFACE
The standard wall thermostat interface provides a
simple to install thermostat connection. The unit has
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
wall sleeve.
— It is recommended to include extra wires
in case a wire breaks or is cut during
installation.
— The thermostat is ordered separately and
a Gree PTAC approved thermostat is
recommended, see the accessory chart in
the back.

APPLICATIONS
•Hotels and motels
•Nursing homes and assisted living care
centers
•Offices
•Apartments
•Single--family dwellings
•Home conversions and residential add--ons
NEW CONSTRUCTION
ADVANTAGES FOR NEW
CONSTRUCTION
Design Flexibility for the Architect/Engineer
•Whisper--quiet performance, indoors and out
•No bulky duct system
•No separate equipment room
•No water towers or additional cooling
equipment
•No complex match--up of different HVAC
components
•Less sensitivitytobuilding orientation (sun,
wind, shade)
•Optional architectural grille to permit custom
exterior appearance
Initial Cost Savings for the Building Owner
•No expensive component HVAC system
purchase
•No equipment room or maintenance
engineering staff
•Two--part delivery to minimize on--site
damage
•Weather--protected wall sleeve that goes in
placeduring construction; chassis that slides
in place after construction
•No seasonal changeover required for cooling
or heating -- units are self--contained comfort
systems
Lower Operating Costs and Reliable Comfort
for The Occupant
•Heatpump models offer substantial savings
over models with conventional electric
resistance heaters
•Individual units allow tenants to choose the
degree of comfort and operatingeconomy.
•Rapid servicing reducesdowntime: complete
chassis can be replaced in minutes without
disrupting other occupants.
•Eachunitoperates independently of other
units in thebuilding. No dependency by
building on central HVAC system.
RETROFIT/REPLACEMENT
If youare replacing a unit in an existing wall sleeve,
youroptionsinclude:
•Replacethe 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:
—
— Friedrich T series and ZoneAire wall
sleeves, with a required wall sleeve
extension (see accessory Friedrich
Retrofit Wall Sleeve Adapter).

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.

The following major competitors’ wall
sleeves/grilles: Carrier, GE, Amana,
Trane, Friedrich and Bryant, and NO
accessory retrofit kit is required.
