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.

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.

MOUNTING RAIL

Fig. 5 - Remove Metal Clip on GE Metal Sleeve

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.

ENERGY MANAGEMENT INPUT (FRONT DESK CONTROL)
The controller can handle a switch signal from remote energy management input, called EM signal or front desk

control. Input must be 24VAC. If system receives a 24VAC signal, it will turn unit off; otherwise, the unit runs in
normal control. This function will be disabled under Freeze Guard protection. See Fig. 25 for terminal

connections.
INTELLIGENT SELF-CHECKING CONTROL

Your PTAC has a computer board that continuously checks key components of the unit to ensure they are
operating properly. Under normal operation, unit status indicator (STATUS, on main PCB), light is steadily ON.

If there is a major problem, the unit will shut down and display a diagnostic failure code on the unit's display. If
it is only a minor failure and unit is correcting the fault by itself, the diagnostic code will be flashed on the status

LED that can easily be seen when the front panel is removed (see Fig. 24). Failure STATUS codes are defined
in the table below

• Wall sleeve is not installed level

iCE OR FROST FORMS ON INDOOR COIL

• Low outdoor temperature

• Dirty filters

• Make sure that curtains, blinds or furniture are not restricting or
blocking unit airflow.

• Reset to a lower or higher temperature setting.

• Remove and clean filters.

• Allow sufficient amount of time for unit to heat or cool the room.
Start heating or cooling early before outdoor temperature, cooking

heat or gatherings of people make room uncomfortable.

• Close vent door.

• Check dipswitch settings for desired comfort.

Wait approximately 3 minutes for compressor to start

• The unit may be in a diagnostic condition. Check Intelligent Self-
checking Control section to determine if unit has had a failure.

• The unit may be set for °C (instead of °F), see the keypad
configuration section

• Clicking, gurgling and whooshing noises are normal during
operation of unit.

• If a drain kit has not been installed, condensation runoff during

very hot and humid weather is normal. See Note 2. If a drain kit has
been installed and is connected to a drain system, check gaskets

and fittings around drain for leaks and plugs.

• Wall sleeve must be installed level for proper drainage of

condensation. Check that installation is level and make any

necessary adjustments.

• When outdoor temperature °is approximately 55 F (12.8°C) or
below, frost may form on the indoor coil when unit is in Cooling

mode. Switch unit to FAN operation until ice or frost melts.

• Remove and clean filters.

COMPRESSOR PROTECTION

• Power may have cycled, so compressor is in a
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 3 minutes.

• Compressor Protection - To prevent short cycling of the
compressor, there is a random startup delay of 3 minutes and a

minimum compressor run time of 3 minutes.

NOTES:

1. If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician.
