NOTES:
1.
The tables above indicate the approximate indoor and outdoor sound levels of an ETAC unit.
Tests were conducted in the Gree Sound Testing Laboratory according to AHRI (Air Conditioning, Heating and Refrigeration Institute) Noise Rating Standard 300 for non-ducted indoor air conditioning equipment.

APPLICATION CONSIDERATIONS
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.
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
temperatu
re during very hot days. The result could be
warm and humid or warm and dry conditioned space.
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 beacool, 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 insufficie
nt 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.
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 sensitivity to building orientation (sun,
wind, shade)
• Optional architectural grille to permit custom
exterior appearance
I nitial Cost Savings for the Buildin
g Owner
• No expensive component HV
AC system
purchase
• No equipment room or maintenance
engineering staff
• Two--part delivery to minimize on--site
damage
• Weather--protected wall sleeve that goes in
place during 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
• Heat pump models offer substantial savings
over models with conventional electric
resistance heaters
• Individual units allow tenants to choose the
degree of comfort and operating economy.
• Rapid servicing reduces downtime
: complete
chassis can be replaced in minutes without
disrupting other occupants.
• Each unit operates independently of other
units in the building. No dependency by
building on central HVAC system.
RETROFIT/REPLACEMENT
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 E-TAC will fit into:
—
— Friedrich T series and ZoneAire wall
sleeves, with a required wall sleeve
extension (see accessory Frie
drich
Retrofit Wall Sleeve Adapter).
E-TAC
Whether you are designing a new structure or
replacing packaged terminal air conditioning units in
an existing building, Gree E-TAC will meet your
needs.
The Gree E-TAC Packaged Terminal Air Conditioning
(E-TAC) 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.
