NOTES:
• The unit will stop running when outdoor temperature
drops below -22°F (-30°C). The unit will resume operation
automatically when the temperature rises above the low
temperature limit.
• To achieve optimal capacity and efficiency at 5°F (-15°C)
and below it is recommended to operate indoor fan in
Turbo Mode.
• It is recommended to have a secondary heating source(s)
available in case the temperature drops below the
operating range.
The following information lists the operating range specific to each model.

31-5000560 Rev. 5 3
Please note system will NOT run normally unless one of the following procedures is completed.
When the system is first powered up, the indoor and outdoor LED display will display “CC”. Please note that this is NOT
an error code. This is an indicator that the system is ready to run the “Preprogrammed System Test”.
The installer can choose one of the two following options:
• Option 1 (Preprogrammed System Test):
– Set the indoor mode to “Heat” or “Cool” and then set the indoor temperature to 77°F (25°C). The preprogrammed
system test will start within five seconds.
• The indoor display will flash “Fn” and “N1”; the outdoor display will flash “N1”.
• The test will continue to run for 18~25 mins, including heating test (display “N2”) and cooling test (display “N3”)
depending on outdoor conditions. For sequence of operation, refer to Installation Manual Section “Energy Star
Models (Installation Capabilities)”.
• Upon completion and passing of all tests, the indoor and outdoor display will show “PS”.
– User can press any button to exit the test mode. The system can now be used normally.
• Option 2 (bypass “Preprogramed System Test”): set the indoor mode to “Dry” mode first and then set the indoor
temperature to 68°F (20°C).
• The indoor display will flash “BP” for five seconds and shut down automatically.
• The system can now be used normally.
Note: The automatic tests can also be by-passed by setting the indoor mode to dry and then setting the temperature
to 68°F (20°C) while the unit is flashing CC after initial power has been applied to the unit. The indoor display should
read BP for 5 seconds then go into stand-by mode. The unit can then be used normally. If installation test mode has been
started, it will not be able to by-pass the test unless the power has been recycled prior to finishing the installation tests.
Note: If the outdoor temperature is exceeding normal operation range, (eg. below -4°F (-20°C) or above 115°F(46°C)),
running pre-programmable test may result in error code. Manufacturer suggests to by-pass the test during the severe
weather and go back to the jobsite and run the test when outdoor temperature permits.
Note: If there is a need to run the pre-programmed installation tests again after successfully completing them initially, set
the remote controller to cool, high fan speed, 60°F (16°C), and then press the sleep button 4 times continuously. After
hearing 5 beeps on the indoor unit, power cycle.
Note: In order to achieve maximum performance at low ambient conditions it is recommend to set fan speed to turbo.

WARNING For your safety, the information in this manual must be followed to minimize the risk of fire,
electric shock, or personal injury.
• Use this equipment only for its intended purpose as
described in this manual.
• This heat pump must be properly installed in
accordance with these instructions before it is used.
• All wiring should be rated for the amperage value listed
on the rating plate. Use only copper wiring.
• All electrical work must be completed by a qualified
electrician and completed in accordance with local and
national building codes.
• Any servicing must be performed by a qualified
individual.
• All heat pumps contain refrigerants, which under federal
law must be removed prior to product disposal. If you
are getting rid of an old product with refrigerants, check
with the company handling disposal.
• These R-410A heat pumps systems require that
contractors and technicians use tools, equipment and
safety standards approved for use with this refrigerant.
DO NOT use equipment certified for R22 refrigerant
only.
WARNING RISK OF ELECTRIC SHOCK. Could cause injury or death.
• An adequate ground is essential before connecting the
power supply.
• Disconnect all connected electric power supplies before
servicing.
• Repair or replace immediately all electrical wiring that
has become frayed or otherwise damaged. Do not use
wiring that shows cracks or abrasion damage along its
length or at either end.
WARNING
This heat pump system is not intended for use by
persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a
person responsible for their safety. Children should be
supervised to ensure that they do not play with the heat
pump system.
To avoid danger of suffocation, keep the plastic bag or
thin film used as the packaging material away from young
children.
Be sure not to allow foreign materials (oil, water,
etc) entering the refrigerant piping. Seal the ends of
refrigerant piping before storage.
For installation purposes, be sure to use the parts
supplied by the manufacturer or other prescribed parts.
The use of non-prescribed parts can cause serious
accidents such as the unit falling, water leakage, electric
shock, or fire.
The rated power supply of this product is 208/230
VAC/60hz/1PH. Verify the voltage is within 187~253 range
before turning the equipment on.
Supply power to the heat pump should be from a
dedicated circuit that meets branch circuit ampacity
requirements.
Use a special branch circuit breaker and receptacle
matched to the power circuit capacity of the heat pump.
(Install in accordance with local technical standard for
electrical equipment.)
Do not extend the power cord.
Perform wiring work in accordance with standards so that
the heat pump can be operated safely and positively.
Install a leakage special branch circuit breaker in
accordance with the related laws and regulations and
electric company standards.

RISK OF FIRE. Could cause injury or death.
• Do not store or use combustible materials, gasoline or other flammable vapors or liquids in the vicinity of this or any
other appliance.
For any service which requires entry into the
refrigerant sealed system, Federal regulations
require that the work is performed by a technician
having a Class II or Universal certification.
Important Safety Information

31-5000560 Rev. 5 5
READ AND SAVE THESE INSTRUCTIONS
For more help, visit GEAppliances.com/ductless or call the consumer help line at 844-487-9443.
It is highly recommended that you do not open or close
the stop valves when the outdoor temperature is below
-5°F (-21°C) as this may cause refrigerant leakage.
Make sure power is turned on for at least 12 hours
after periods of being powered down in an 32 °F (0° C)
environment or lower.
Do not touch the fins of the coil. Touching the coil fins
could result in damage to the fins or personal injury such
as skin rupture.
Ensure the power circuit capacity is adequate for all loads
connected to the electrical service panel. Increase the
conductor and panel capacity if the total electrical loads
exceed the power source capacity.
Contact the power utility if the power provided is below
equipment rating plate requirements.
Be sure to install a breaker of the specified capacity.
Regulation of cables and breaker differs from each
locality, refer in accordance with local rules.
Do not use existing refrigerant lines.
Use refrigerant tubing that is clean and free of any
contamination which may cause damage to the system
including sulfur, copper oxide, dust, metal chips, powder,
oil or water.
Avoid brazing lines together. Use a continuous length of
copper tubing as oxides formed during improper brazing
techniques can damage the equipment.
Do not use copper pipes that have a collapsed, deformed,
or discolored portion (especially on the interior surface).
Otherwise, the expansion valve or capillary tube may
become blocked with contaminants.
Improper line sizing will degrade performance. Peak
pressure of R410A is much higher than R22. Use copper
tubing with adequate wall thickness.
To prevent breaking of the pipe, avoid sharp bends. Bend
the pipe with a radius of curvature of 4 in. (100 mm ) or
more.
If the pipe is bent repeatedly at the same place, it will
break.
CAUTION
• Aluminum electrical wiring may present special
problems - consult a qualified electrician.
• When the unit is in the STOP position, there is still
voltage to the electrical controls.

Step 2 - Installation of the Indoor Unit
A. Select the Indoor location:
• Do not expose the unit to unusual heat sources or steam
outlets.
• Select a location where there are no obstacles in front of
the unit.
• Make sure that condensate drainage can be conveniently
routed away.
• Do not install near a doorway.
• Ensure that the space around the left and right of the unit
is more than 4”. The unit should be installed as high on the
wall as possible but allow a minimum of 4” from the ceiling.
• Use a stud finder to locate and mark stud locations for
mounting and to prevent unnecessary damage to the wall.
• Install in a location that is strong enough to withstand the
full weight and vibration of the unit.
• Leave enough space to allow access for routine
maintenance.
• Select a location that gives easy access to removing and
cleaning air filters.
• Install in a location that is 3 ft. or more away from other
electrical appliances, such as televisions and audio devices.
B. Install the Mounting Plate
• Remove plastic bag, tape, and mounting plate from the
back of the indoor unit.
• Place the mounting plate on the wall in the desired location
taking into account the minimum clearances necessary for
proper operation.
• Using a level, verify that the mounting plate is horizontal
and mark the screw locations.
• Attach the mounting plate to the wall with the supplied
screws.
• Wall anchors are supplied if not able to align all screw holes
with studs.
• Be sure that the mounting plate has been attached firmly
and that applied weight is evenly distributed by each
screw. (At least one screw in wall stud, others can use wall
anchors.)
• The piping for the indoor unit may be routed to and from
the unit in one of several directions: left, left rear, right, right
rear, or right below.
NOTES:
• OD unit cannot hang from a ceiling or be stacked.
• Ensure that accumulated snow, debris, etc… will not block the
air inlet or the coil exchanger if installing the OD unit with a
fence or rail guard around it.
• Ensure ventilation in case of refrigerant leakage. R-410A is a
safe, nontoxic, and nonflammable refrigerant.
• Avoid installing the OD unit where corrosive gases, such as
sulfur oxides, ammonia, and sulfurous gas are produced. If
unavoidable, consult with an installation specialist about using
a corrosion-proof or anti-rust additive to protect the unit coils.
• Do not install the outdoor unit near the edge of a balcony.
Otherwise, children may climb onto the outdoor unit and fall
off of the balcony.
• Do not install the outdoor unit in the following areas: Areas
heavily laden with oil or greasy vapors such as kitchens. Oils
and grease will create sticky layer on the coil and also cause
drainage problems, thus degrade unit performance.
• Corrosive areas that can potentially have combustible
gas leaks, contain suspended fibers or flammable dust, or
flammables such as paint thinner or gasoline can cause fires.
• Areas that contain small animals, rodents, reptiles or insects
that can infiltrate the equipment and cause damage to internal
components.
• Area where animals may urinate on the unit or ammonia may
be generated.
• Install as necessary a protective fence or the like to prevent
their access if the outdoor unit must be installed in an area
within easy reach of the general public.
• Take appropriate measures to protect it from those elements
If the outdoor unit is installed in a cold region that is affected
by snow accumulation, snow fall, or freezing. To ensure a
stable operating, install inlet and outlet ducts.
• Make sure the outdoor unit is installed level and is stable.
Install snow protection hood as necessary.
• Avoid salty places such as the seaside for installation where
air conditioner trouble is liable to occur.
• Install the outdoor unit in a location that is away from exhaust
or the vent ports that discharge vapor, soot, dust, or debris.
• Install the unit where it will not be tilted by more than 3°.
However, do not install the unit with it tilted towards the side
containing the compressor.
• When installing the outdoor unit where it may exposed to
strong wind, fasten it securely.
• It is recommended that unit be installed under a canopy or
elevated on a high stand.
• Protect the drain line from freezing in areas where
temperature drops to 32°F (0°C) or lower.
• Please set up the outdoor unit in a high place and please
do not arrange the frame of installed stand under the drain
port, because the water dropped from the drain port repeats
freezing and accumulating, and may block the drain port.
• Do not use mineral oils on flared parts. Prevent mineral oil
from entering the refrigerant system. Introduction of mineral oil
may reduce the system life.
• Be sure to use an inert gas such as nitrogen while brazing
any refrigerant lines to prevent any oxidation
• Be sure not to exceed refrigerant tubing length limits for
different models to ensure smooth operation of the unit.
Otherwise the equipment life cannot be guaranteed.

Installation Instructions
D. Electrical Connections for the Indoor Unit
NOTE: Be certain all wiring complies with local building
codes and NEC and that the supply voltage for this system is
correct.
• Place the indoor unit on a solid work surface before making
electrical connections.
• To make the electrical connections for the indoor unit, both
the outer plastic and inner galvanized steel cover plate must
be removed.
• Raise the front cover to access the screws for removing
these covers.
• Route the 14/4 AWG stranded wiring through the slot in the
back of the unit and into the front access panel.
• Using a wire stripper, remove the insulation and separate
the 4 wires.
• Make wiring connections at each terminal according to
wiring diagram. (Take note of the color of the wire at each
terminal and ensure the wires are connected to the outdoor
unit accordingly.)
• Ensure each wire is under the screw terminal plate and the
plate is tightened.
• Ensure the 14/4 cable is secured under the strain relief
bracket.
• Replace both cover plates and lower the front casing after
the terminal block wiring is completed.
E. Mount Indoor Unit to Mounting Plate
• Bundle the refrigerant piping, drain piping, and wiring
with tape and carefully route the bundle through the
piping hole.
• With the top of the indoor unit closer to the wall, hang
the indoor unit on the upper hooks of the mounting
plate. Slide the unit slightly side to side to verify
proper placement.
• Rotate the lower portion of the indoor unit to the
mounting plate, pushing the unit up slightly, rotate the
lower part of the unit fully against the wall, then pull
down do the lower hooks engage the brackets. (see
illustration)
• Verify the unit is secured and flush to the wall.
• Indoor Unit installation is finished at this time.
F. Condensate Drainage Pipe
• Verify the condensate drain line has a constant pitch
downward for proper water flow. There should be no
kinks or rises in the tubing which may cause a trapping
effect of the water (see illustration).
Optional: Can use PVC pipe by connecting a 1” ID PVC
pipe to the drain line coming out of the wall and running to
desired location.

G. To Remove the Indoor Unit
• Slightly raise the entire unit.
• Pull the lower portion of the unit off the lower hooks and pull
slightly away from the wall.
• Lift the upper portion of the unit off the upper hooks.
C. Install the Tubing
• Always use new clean copper tubing. Never reuse tubing if
replacing an existing system.
• Measure and mark the location where the piping hole is to
be drilled.
• Follow these steps to move the drain pipe if pipe location
will be on the left side of the unit.
1. Remove the stopper in the left drain hole and knockout the
molded plug inside the port.
2. Transfer the corrugate drain hose from the right side to the
left side.
3. Insert stopper into right side drain port. Using soap as
a lubricant and a small screwdriver will allow for easier
seating of the stopper.
• Drill the lineset hole using a 2 1/4” hole saw. Angle the drill
with a downward pitch to the outside wall so that the outside
wall hole will be at least a ¼” lower than the inside hole.
This allows for proper drainage of condensate.
• Install the lineset hole flange at the hole opening on the
inside wall.
NOTE: The flange is prescored. It may be necessary to
modify the flange to fit properly behind the wall unit housing.

A cardboard template for the mounting plate is included with many of the indoor units. It serves as an easier way of
determining where to mount the wall bracket and where to cut the hole for piping.
NOTE: Some models may not have a cardboard template, in this case, a manual measurement is needed to
determine the piping hole location.
When mounting the unit, use a stud finder to secure the upper-most holes to the structure of the building. Use load
rated anchors to attach other portions of the bracket to the wall.
