E. Air Flow System:
For superior sound and comfort, the airflow
system shall consist of two, direct--drive
permanently lubricated fan motors. The outdoor
fan motor will be single speed, with a dynamically
balanced, corrosion resistant, multi-blade axial
flow design, with integrated slinger ring. The indoor
fan motor will be three speeds, with a dynamically
balanced aluminum, tangential blower wheel, to
assure uniform air distribution and optimal sound.
Both Fan Motors shall be of an enclosed design to
reduce the effects of moisture and corrosion.
F. Compressor & Refrigerant:
The rotary--type Compressor shall be fully
hermetic with internal and external vibration
isolation. The refrigeration system will be sealed
and contain a full refrigerant charge (R410A).
G. Coils:
Condenser and evaporator coils to be constructed
of high-efficiency copper and aluminum, necessary
to achieve EER and COP rating, as specified on
the chassis name plate.
H. Factory --Installed Electr
ic Heater:
The factory--installed, open coil type, electric
heater is standard in heat/cool and heat pump
chassis. The electric heater shall contain both an
automatic reset and a one--shot over temperature
protection device. The heating capacity of the
electric heater shall be as identified on the
Contract drawing schedule and in the
specifications.
I. Controls:
All standard models shall be equipped with
electronics, for added features and improved
reliability of the unit.
The chassis shall have an easy to operate, user
friendly, electronic display with simple to push,
large digital buttons. All controls will be easily
accessible and covered by a hinged door.
The mode selection control shall consist of OFF,
FAN ONLY, HEAT, COOL and DRY operations.
There will be 3 optional Fan Speed Options, LOW,
MED or HIGH. The temperature selection will be
controlled by color coded, simple to operate
warmer and cooler buttons. The upper and lower
setpoint temperature limits, can be easily
configured.
All models shall have a configuration dipswitch,
easily accessible for optimal comfort settings,
CONTINUOUS or CYCLE fan mode in HEATING,
CONTINUOUS or CYCLE fan mode in COOLING,
FREEZE GUARD enabled or disabled, WALL
THERMOSTAT enabled or disabled,
EMERGENCY HEAT (for heatpumps), and 4
optional SETPOINT LIMIT selections.
Fan cycle configuration switches, will allow
continuous fan operation for maximum comfort or
cycle operation for maximum energy savings.
Settings can be differe
nt for both heating and
cooling operations, for maximum comfort and
efficiency.
All standard models shall have Temperature
Limiting control, with four easy to configure
settings. Temperature limiting allows a room
temperature range to be set to avoid extreme
temperature settings and to maximize savings.
Emergency Heat Switch (Heat Pump Models
Only) shall disable the compressor in heating
mode and only allow the use of electric heat
during heating cycles. The Emergency Heat switch
is active at all outdoor ambient temperatures.
All units shall be capable of interfacing to a wall
thermostat; haveablank
out label to cover the
control panel for wall thermostat applications;
and have a removable wall thermostat terminal
block, to simplify field wiring. No additional
field--installed kits shall be required.
Wall thermostat interface shall provide two fan
speed selections to maximize comfort.
Compatible with2wire central desk control
systems.
Freeze Guard to automatically activate the electric
heater and indoor fan to warm the room, to
prevent damage from freezing temperatures.
Freeze guard will be active as long as there is
power supplied to the unit. Unit shall have the
ability to disable Freeze guard, if needed.
Un
it shall have the option to display temperature
in
˚
F or
˚
C.
Unit will have memory; in case power is lost, unit
will return to all previous settings.
Unit will havearandom compressor restart after a
power outage, to prevent power surges due to
many units turning on at the same time.
Room temperature sensing shall useaSolid state
thermostat control.

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 c
omponent 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
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 reduce
s 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 F
riedrich
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.
