UNIT FEATURES
2
This premium unit has many exciting features that differ from
those of most 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 premium unit has a computer that
utilizes real-time diagnostics to prolong the life of your unit.
There is a LED indicator on the control board, behind the
front panel, that flashes an error code if the unit detects a
malfunction. In many cases, the unit automatically clears the
malfunction and continues operating without interruption. In
some cases, the malfunction cannot be cleared and the unit
requires service. In those cases, an “Fx” failure mode will
appear on the digital display. For a detailed list of all error
codes and “Fx” conditions, see Table 6 – Status LED
Indicator Definitions.
• Memory – Your premium unit also has memory. If power is
lost, all of the control settings (setpoint temperature, 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 – Not only does the unit have two fan motors and a tangential blower wheel for optimum sound control, the
indoor fan always runs at least 10 seconds before the compressor starts, to help reduce noise from when the compressor starts.
• Random compressor restart – To help prevent power surges after a power outage (from several PTACs starting at the same
time), the compressor is equipped with a 2:45 to 3:15 random restart delay feature. Whenever the unit is plugged in, or the power
has been restarted, a random compressor restart will occur.
• Compressor protection – To prevent the compressor from short cycling and to maximize its life, there is a random start-up
delay of three minutes on the compressor and a minimum compressor run time of three minutes.
•Automatic freeze protection – Automatically keeps the room temperature from getting too cold, when water pipes might
freeze. If the unit is configured for freeze protection ( the default condition), then whenever power is supplied to the unit, if the
unit senses that the temperature is below 40°F, the fan motor and electric heater turn on and warm the room to 50°F. If freeze
protection is not required, change the configuration switch to turn the feature off (see section on unit configuration).
• Automatic defrost protection (for heat-pump models only) – When the outdoor temperature gets too cold (approx. 35°F)
and the unit can no longer effectively heat with the compressor, the unit automatically switches to electric heating. The unit then
heats with electric heat until the outside temperature rises enough (approx. 40°F) for the compressor to be used again.
• Automatic quick warm-up (for heat pump models only) -- If the room temperature falls to 5°F below the set temperature, the
reverse-cycle heat turns off and the electric strip heat turns on for one cycle, until heating is satisfied.
•LED indicators and buttons – The touch pad has buttons for MODE, FANSPEED, ON/OFF,
SETPOINT UP and SETPOINT DOWN. It also has LED lights that correspond to the mode, fan speed and setpoint operation,
to indicate the unitʼs status. The LED lights below MODE, FAN, COOL, and HEAT, indicate the active operating mode. The LED
lights below the Fan button, Low, Med and Hi, indicate the selected fan speed. The LED light located in the lower right corner
shows whether the unit is on or off. If the unit is ON, the LED will be green. If the unit is OFF, the LED will be red.
• Configure fan to optimize selected application – The unit can optimize a selected application by configuring the fan to run
in continuous mode or to cycle on and off with the compressor and electric heater (can be different for both heating and cooling
modes). In cycle mode, the fan continues to run after the compressor or electric heater stops in order blow out any residual heat
or cool left in the coil.

• Unit configuration – There are many different possible configurations, set with both DIP switches and the digital keypad, that
allow you to configure the unit for your exact needs. See the section on unit configuration for more details. The following are the
configuration selections that have not previously been mentioned:
• °F or °C – The unit can display temperatures in either °F or °C.
• Indoor temperature sensor biasing – Optimize the room temperature sensor reading to your exact needs (one for cooling
and another for heating).
• Emergency heat (for heat pump only) – Disable the compressor while the heat mode is running (heat only with electric heat).
• Display setpoint OR room temperature – The unit can be configured to display the room temperature OR the setpoint temperature
only, in the heat and cool modes. See section on unit configuration for more details.
• Limit the setpoint range – The unit can be configured to limit the setpoint range. The display will always show the complete
setpoint range, but the controlled setpoint will be limited to the selected minimum and maximum setpoint. See section on unit
configuration for more details.
• Energy management – Also 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 24 VAC from this input, it automatically turns itself off. If no voltage is detected from the
input, the unit runs normally.
• Wall thermostat control – A wired wall thermostat can be connected to the unit. If this is done, the unit must be configured to
disable the keypad. See section on wired inputs and unit configuration for more details.

WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death and/or property damage.
DO NOT alter cord or plug. DO NOT use an extension cord.
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). A power cord accessory kit must be ordered to connect the
unit to the outlet. If the unit is to be hard wired, a hard wire accessory kit must be ordered.
LEGEND
AWG --- American Wire Gauge
* Single circuit from main box.
† Based on copper wire at 60°C temperature rating.
Table 1—SUGGESTED BRANCH CIRCUITWIRE SIZES*
Wire size
Use the recommended wire size provided in Table 1 and install a single branch circuit. All wiring must comply with local
and national codes. All units are designed to operate from ONE single branch circuit only.
Grounding
For safety and protection, the unit is grounded through the power cord plug or through a separate ground wire provided on
hard-wired units. Be sure that the branch circuit or general purpose outlet is grounded.
Cord-connected units
The 250V field supplied outlet must match the plug for the standard 208/230V units and be within reach of the power cord.
The standard cord-connected 265V units require an electrical subbase accessory. Refer to Table 2 for the required receptacle
and fuse type.
Power cord protection
The power cord for 230/208V units provides power cord fire protection. Unit power automatically turns off when unsafe
conditions are detected. Power to the unit can be restored by pressing the reset button on the plug head.

Upon completing the unit installation of 230/208V models, an operational check should be performed using the TEST/RESET
buttons on the plug head.
NOTE: The 265V models do not include this feature, as they require the electrical subbase accessory.
IMPORTANT: For 265V units, if power cord accessory is selected, the cord is only 18” long and must plug into the
electrical 265V subbase receptacle accessory.
Be sure that your outlet matches the plugʼs prong configuration and that the power cord will reach it.
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.
NOTE: Use copper conductors only.
INSTALLATION
5
Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended that a
GREE or Carrier sleeve be used.
These units can retrofit General Electric, Amana, Trane, and Friedrich sleeves/grills (be sure outdoor grill is installed on the
sleeve). See Table 3 for details.
For any sleeve retrofit applications, be sure that the foam seals (factory-installed on the tube sheets) provide a good seal
between the grill and outdoor coil tube sheets. These foam seals provide a barrier to separate the air exiting from the outdoor
coil and the air coming in (known as air recirculation).
• CHASSIS INSTALLATION
UNIT DAMAGE AND/OR OPERATION HAZARD
Failure to follow this caution may result in equipment
damage or improper operation. For retrofit applications,
foam seals on outdoor coil tube sheets must make a seal
between the coil and the grill or loss of performance and
premature damage to the major components
can result.

ELECTRICAL SHOCK HAZARD
• Failure to follow this warning could result in personal injury or death.
• Disconnect all power to the unit to avoid possible electrical shock during installation.
WARNING
INSTALLATION OF A GREE OR CARRIER WALL SLEEVE USING A NON-GREE GRILL
This application has become more common due to pre-manufactured windows with built-in grills or renovations where a GREE
or Carrier sleeve is used with an existing non-GREE grill.
Use of a GREE or Carrier wall sleeve with a non-GREE grill requires the installation of a baffle accessory kit
(see Fig. 8), which ensures a good seal between the unit and the exterior grill to prevent air recirculation. Air recirculation is a
large contributor to performance loss and premature damage to major components.
NOTES: The GREE stamped grill is interchangeable with CARRIER'S.
NOTE: Contact your unitʼs supplier to get the kit. It
may differ from the one shown above.

• INTELLIGENT SELF-CHECKING CONTROL
Your GREE PTAC has a computer that continuously checks key components of the unit to ensure they are operating properly.
Under normal operation, the unit status indicator (STATUS, on main PCB), light is always ON. If there is a major problem, the
unit will shut down and display a diagnostic failure code on the unitʼs display screen. If it is only a minor failure and the unit
corrects the fault by itself, the diagnostic code will flash on the LED status display and can easily be seen when the front panel
is removed (see Fig. 24). Failure STATUS codes are defined in the table below:

TEMP CONTROL FAN, MODE& OPERATION
Fig. 26 – PTAC CONTROLS
• ABOUT THE CONTROLS ON YOUR UNIT
NOTE: In case of a power failure, the unit will remember the last programmed settings and will revert to those settings when
restarted.
1. TEMP CONTROL
Temp Control is used to maintain room temperature. The compressor will cycle on and off to keep the room at the requested
level of comfort.
COOLER – Lowers the temperature. (Minimum temperature setting is 61°F/16°C)
WARMER – Raises the temperature. (Maximum temperature setting is 86°F/30°C)
2. FAN SPEED, MODE & ON/OFF
FAN SPEED – Sets the fan operation to HI, MED, or LO speed.
MODE-COOL – For cooling.
MODE-HEAT – For heating.
NOTE: If the unit is a heat pump, raising the heat setting 5°F will cause unit to use its electric heating elements for one cycle
in order to reach the new requested temperature quickly.
M
ODE-FAN – For fan only.
ON/OFF – Turns the unit on or off.
NOTE: The LED light above the ON/OFF button will be green when unit is ON and red when the unit is OFF.
A
ll other LEDs are off when unit is set to OFF mode.
NOTE: Power remains connected to unit.
CARE AND CLEANING
15
• FRONT PANEL AND CASE
Turn unit off and disconnect power supply.
To clean, use water and a mild detergent. DO NOT use bleach or abrasives. Some commercial cleaners may damage the
plastic parts.
• OUTDOOR COIL
Coil on outdoor side of unit should be checked regularly. Unit will need to be removed to inspect dirt build-up that will occur on
the inside of the coil. If clogged with dirt or soot, coil should be professionally cleaned.
NOTE: Never use a high-pressure spray on coil.
• BASE PAN
In some installations, dirt or other debris may be blown into unit from outside and settle in base pan (bottom of unit).
In some areas of the United States, a gel-like substance may be seen in the base pan. Check base pan periodically and
clean, if necessary.
• AIR FILTERS
UNIT DAMAGE HAZARD
•Failure to follow this caution may result in equipment
damage or improper operation.
•Airflow restriction may cause damage to the unit.
CAUTION
Coils
Grill
Clean inside and outside of outdoor coils regularly.
Fig. 27 – Outdoor coil
IMPORTANT : TURN UNIT OFF BEFORE CLEANING
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not operate unit without filters in place. If a filter becomes torn or damaged, it should be replaced immediately.
Operating without filters in place or with damaged filters will allow dirt and dust to reach indoor coil and reduce cooling,
heating, airflow and efficiency of unit. Airflow restriction may cause damage to unit.
CAUTION
The most important thing you can do to maintain unit efficiency is to clean the filters at least every 30 days (or more often
depending on application). Clogged filters reduce cooling, heating and airflow.
Keeping filters clean will:
• Decrease operating costs
• Save energy
• Prevent clogged indoor coil
• Reduce risk of premature component failure
To clean air filters:
• Vacuum off heavy dirt.
• Run water through filters.
• Dry thoroughly before replacing.

time delay (approx. three minutes) when starting
the compressor after a power outage (or restarting
after it has been turned off), to prevent tripping of
the compressor overload.
DISPLAY HAS STRANGE
NUMBERS/CHARACTERS ON IT
ICE OR FROST FORMS ON INDOOR COIL
• Low outdoor temperature
• Dirty filters
COMPRESSOR PROTECTION
• Power may have cycled, so compressor is in restart
protection.
• Random compressor restart – Whenever the unit is plugged in, or
power has been restarted, a random compressor restart will occur.
After a power outage, the compressor will restart after approximately
t
hree minutes.
• Compressor protection – To prevent the compressor from short
cycling, there is a random startup delay of three minutes and a minimum
compressor run time of three minutes.
• When outdoor temperature is approximately 55°F or below, frost may
form on the indoor coil when unit is in COOL mode. Switch unit to
FAN operation until ice or frost melts.
