UNIT FEATURES
Fig. 2 - Model GA
This Premium unit 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 Premium 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 kind 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 Table 6 -
Status LED Indicator Definitions for further details.
. Memory - Your Premium unit also has memory. If
power is lost, all of the control settings (setpoint,
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 unit is also
the quietest PTAC ever. 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 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 power has been restarted, a random compressor
restart will occur.
. Compressor Protection - To prevent short cycling
of the compressor and maximize it's life, there is a
random start-up delay of 3 minutes on the
compressor and a minimum compressor run time of 3
minutes.
. Automatic room freeze protection - automatically
will keep the temperature in the room from getting
too cold, where water pipes might freeze. If the unit
is configured for the freeze protection feature to be
active (which is the default condition), then whenever
power is supplied to the unit, if the unit senses
temperature below 40°F (4.4°C), the fan motor and
electric heater are turned on and will warm the room
to 50 ° F (10°C). 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. 40°F / 4.4°C) 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 outside
temperature rises enough (approx. 40°F / 4.4°C), so
the compressor can be used again.
. 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.
. LED Indicator's 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
HEAT, indicate what operating mode is active. The
LEDs below the Fan button, Low, Med and Hi,
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.
. Configure Fan to Optimize Selected Application -
Unit can be optimized to selected application by
configuring the fan to run in continuous mode or cycle
on and off with the compressor and electric heater (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 in order blow off
any residual heat or coo! left on coi!.
UNIT FEATURES CONTINUED
* Unit Configuration - There are many different
configuration possibilities, through both dipswitches
and the digital keypad, that allow you to configure
the unit for your exact application. See section on
unit configuration for more details. Following are the
configuration selections that have not previously been
mentioned:
* °F or °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)..
* Emergency Heat (for Heat Pump Only) - Disable
the compressor during heating mode operation (heat
only with Electric Heat).
* 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.
* 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 setpoint 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 wa!l
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.

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 or use an extension cord.
POWER CONNECTION OPTIONS
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 ordered to connect the unit to the outlet. If the
unit is to be hard wired, an accessory hard wire kit
must be ordered.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Using a 30 amp cord on -U07 and -U09 models could
result in damage the unit. For these models, use 15 or 20
amp power cords only.
IMPORTANT: For 265V units, if power cord
accessory option is selected, the cord is only 18 inches
long and must plug into the accessory electrical
265V subbase.
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.
ALL UNITS
Wire Size
Use recommended wire size given in Table 1 and
install a single branch circuit. All wiring must

INSTALLATION
Proper installation is the responsibility of the
installer.
Product failure due to improper installation is not
covered under the Warranty.
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications
where unit is a replacement, it is recommended that a
Gree 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
tube sheets. These foam seals provide a barrier to
separate outdoor coil leaving air from mixing with
the outdoor incoming air (known as air recircula-
tion).
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 grille or
loss of performance and premature damage to the maior
components can result.

This application has become more common due to
pre-manufactured windows with built-in grilles or
renovations where a Gree sleeve is used with an
existing non-Gree gri!le.
Use of a Gree wall sleeve with a non-Gree grille
requires insta!lation of an Accessory Baffle Kit (see
Fig. 7), which ensures a good seal between the unit
and exterior grille to prevent air recirculation. Air
recirculation is a large contributor to performance
loss and premature damage to major components.
CONDENSATE REMOVAL SYSTEM
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 coi! 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 be!ow 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.

KIT-4PK) and a building condensate drain
system is recommended.
