UNIT FEATURES
This ETAC II has many exciting features which are different than those found on standard PTAC
models. The owner must be familiar with these features in order to fully understand the operation
and capability of the unit.
• Intelligence – Your ETAC II unit has an on board computer that utilizes real time diagnostics
to prolong the life of your unit. There is an LED indicator on the control board, behind the front
panel, that will flash an error code if the unit has detected some type of fault condition. In
many cases, the unit will automatically clear the fault condition and continue operating with
no interruption. In some cases, the condition cannot be cleared and the unit will require service.
In those cases, an “Fx” failure mode will be displayed on the digital display. For a detailed list
of all error codes and “Fx” conditions, see Intelligent Self Checking and Control section on page
20 for further details.
• Memory – Your ETAC II unit also has memory. If power is lost, all of the control settings (set-
point, mode, fan speed, on/off and configuration) are remembered. So when power is restored,
the unit will start back up in the mode (and configuration) it was in, when power was lost.
• Premium Sound – Your Premium ETAC II is also the quietest Gree PTAC. Not only does it have
2 fan motors and a tangential blower wheel for optimum sound, the indoor fan will always run
a minimum of 10 seconds before the compressor, to help reduce any compressor starting noise.
• Random Compressor Restart – To help prevent power surges after a power outage (from
many of your ETAC IIs starting at the same time), the compressor is equipped with a 165 to
195 second random restart delay feature. Whenever the unit is plugged in, or power has been
restarted, a random compressor restart will occur.
• Dry Mode – will help to manage and reduce the humidity in the room, making it more
comfortable. In DRY mode, the unit will modulate cooling mode at low fan speed until the
room temperature is 4 deg. F below the room temperature setting regardless of fan mode
selection. Dry mode should not be considered a substitute for a stand alone dehumidifier.
• Compressor Protection – To prevent short cycling of the compressor and maximize its life,
there is a 3 minute start-up delay on the compressor after power up and between operating
cycles and a minimum compressor run time of 3 minutes.

UNIT FEATURES
• Unit Configuration – There are many different configuration possibilities, through both dip
switches and the digital keypad, that allow you to configure the unit for your exact application.
See section on unit configuration for more details. The following are the configuration selections
that have not previously been mentioned:
• Fahrenheit °F or Celsius °C – The unit can display in either °F or °C.
• Indoor Temperature Sensor Biasing – Optimize the room temperature sensor reading
to your exact application (one for cooling and another for heating).
• Display Setpoint or Room Temperature – The unit can be configured to display the
room temperature OR setpoint only, during heating and cooling modes. See section on
unit configuration for more details.
•
Emergency eat (for eat Pump Only) – In the event the compressor becomes non-opera-
tional, it can be disabled during heating mode allowing heating with the electric heater only.
• Limit the Setpoint Range – The unit can be configured to limit the controlling setpoint
range. The display will always show the complete setpoint range, but the controlling
setpoint will be limited to the configured minimum and maximum setpoints selected.
See section on unit configuration for more details.
• Energy Management – Sometimes known as Front Desk Control, an input is provided so
that the unit can be manually disabled from a different location. If the unit detects 24vac
on this input, it will automatically turn itself off. If no voltage is detected on the input, the
unit will run normally.
• Wall Thermostat Control – A wired wall thermostat can be connected to the unit. If it is,
the unit must be configured to disable the keypad. See section on wired inputs and unit
configuration for more details.
• Automatic Quick Warm-up (for heat pump models only) – If the room temperature falls to
5°F (2.8°C) below the set point temperature, the reverse cycle heat is shut off and the electric
strip heat is turned on for one cycle, until heating is satisfied. Then it reverts back to heat pump.
• Automatic defrost protection (for heat pump models only) – When the outdoor temperature
gets too cold and the unit can no longer effectively heat with the compressor, the unit will
automatically switch to electric heating. The unit will then heat with electric heat until the out-
side temperature rises enough to defrost the outdoor coil, so the compressor can be used again.
• Automatic room freeze protection – When the room is unoccupied for long periods during the
colder months, the unit will automatically keep the room between 40°F (4.4°C) and 50°F (10°C).
Room freeze protection can be disabled by unit configuration dip switches. See System
Configuration section for more information.

UNIT FEATURES
• LED Indicators and Buttons – The touch pad has buttons for MODE, FAN SPEED, ON/OFF,
SETPOINT UP and SETPOINT DOWN. It also has LEDs that correspond to the mode, fan speed
and setpoint operation, to indicate the unit’s status. The LEDs below the mode button, FAN,
COOL, and EAT, indicate what operating mode is active. The LEDs below the Fan button, Low,
i and Auto, indicate the fan speed that is selected. The LED located in the lower right corner is
the unit On/Off status LED. If the unit is in ON mode, the LED will be green. If the unit is OFF,
the LED will be red.
• Configurable Indoor Fan – The indoor fan can be configured to run in continuous mode or
cycle on and off with the compressor and electric heater (this function can be different for
both heating and cooling modes). In cycle mode, fan will continue to run 60 seconds after
compressor or electric heater stops to remove residual heat and cool off of the coil.

CONDENSATE REMOVAL SYSTEM
ETAC II has a new condensate (water) disposal
system. The outdoor fan prop has a built in slinger
ring which draws condensate water and sprays
it 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 base pan to boost operating efficiency.
All heat pump units contain a condensate drain valve. This temperature activated drain valve opens
when the outdoor temperature drops below 55°F (12.8°C) to prevent water from freezing in the
base pan. The water drains from the unit though the wall sleeve and out the wall sleeve’s rear
condensate drainage holes. If the condensate drain kit accessory is attached to the wall sleeve,
water will drain through the condensate drain tube.
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-1PK) and a building condensate drain system is recommended.

ALL UNITS
WIRE SIZE
Use recommended wire size given in Table 1 and install on a single branch circuit. All wiring must
comply with local and national codes. All units are designed to operate off ONE single
branch circuit only.
ELECTRICAL DATA
ELECTRICAL SHOC HAZARD – Failure to follow this warning could result in personal
injury or death and/or property damage. DO NOT use an extension cord.
POWER CONNECTION OPTIONS
The appropriate power cord accessory kit is determined by the voltage, and amperage of the branch
circuit. The unit does not come with a power cord (or hard wire kit). An accessory power cord kit must
be installed on the unit. If the unit is to be hard wired, an accessory hard wire kit must be ordered.
Be sure that your outlet matches the appropriate blade configuration of the plug and that it is
within reach of the service cord. All wiring, including installation of the receptacle, must be in
accordance with the NEC and local codes, ordinances and regulations. National codes require the
use of an arc fault or leakage current detection device on all 208/230V power cords. Be sure to
select the correct cord for your installation.
IMPORTANT: For 265V units, the power cord is only 18 inches long and must plug
into the accessory electrical 265V subbase.

INSTALLATION
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended
that a standard wall sleeve be used.
These units can retrofit Carrier, General Electric, Amana, Trane, and Friedrich sleeves/grilles (be sure
outdoor grille is installed on the sleeve). See Table 3 for details. Gree engineering must approve any
other retrofit application.
For competitive retrofit applications, be sure that the foam seals (factory-installed on the tube
sheets) provide a good seal between the grille and outdoor coil. These foam seals provide
a barrier to separate outdoor coil discharge air from mixing with the outdoor
incoming air (known as air recirculation). Baffles may be required when using
non-Gree grills.
