IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
For your safety, the information in this manual must be followed to minimize the risk of fire, electric
shock or personal injury.
SAFETY PRECAUTIONS
Use this appliance only for its intended
purpose as described in this Owner’s
Manual.
This air conditioner must be properly
installed in accordance with the Installation
Instructions before it is used.
Never unplug your air conditioner by pulling
on the power cord. Always grip plug firmly
and pull straight out from the receptacle.
Replace immediately all electric service
cords that have become frayed or otherwise
damaged. A damaged power supply cord
must be replaced with a new power supply
cord obtained from the manufacturer and
not repaired. Do not use a cord that shows
cracks or abrasion damage along its length
or at either the plug or connector end.
Turn the unit OFF and unplug your air
conditioner before cleaning.
GE does not support any servicing of the
air conditioner. We strongly recommend
that you do not attempt to service the air
conditioner yourself.
For your safety…do not store or use
combustible materials, gasoline or other
flammable vapors or liquids in the vicinity
of this or any other appliance.
All air conditioners 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 about
what to do.
If the receptacle does not match the plug,
the receptacle must be changed out by a
qualified electrician.
These R410A air conditioning systems
require contractors and technicians to
use tools, equipment and safety standards
approved for use with this refrigerant.
DO NOT use equipment certified for
R22 refrigerant only.
HOW TO CONNECT ELECTRICITY
Do not, under any circumstances, cut or remove
the third (ground) prong from the power cord.
For personal safety, this appliance must be
properly grounded.
DO NOT use an adapter plug with this appliance.
The power cord of this appliance is equipped
with a 3-prong (grounding) plug which mates
with a standard 3-prong (grounding) wall outlet
to minimize the possibility of electric
shock hazard from this appliance.
Power cord includes a current interrupter device.
A test and reset button is provided on the plug
case. The device should be tested on a periodic
basis by first pressing the TEST button and
then the RESET button while plugged into the
outlet. If the TEST button does not trip or if the
RESET button will not stay engaged, discontinue
use of the air conditioner and contact a qualified
2
service technician.
Have the wall outlet and circuit checked by
a qualified electrician to make sure the outlet
is properly grounded.
Where a 2-prong wall outlet is encountered,
it is your personal responsibility and obligation to
have it replaced with a properly grounded
3-prong wall outlet.
The air conditioner should always be plugged
into its own individual electrical outlet which has
a voltage rating that matches the rating plate.
This provides the best performance and also
prevents overloading house wiring circuits which
could cause a fire hazard from overheated wires.
See the Installation Instructions, Electrical
Requirements section for specific electrical
connection requirements.

Do Not Operate in Freezing Outdoor Conditions
This cool-only air conditioner was not designed for
freezing outdoor conditions. It must not be used in
freezing outdoor conditions.
Remote Control
To ensure proper operation, aim the remote
control at the signal receiver on the air
conditioner.
The remote control signal has a range of
up to 20 feet.
Make sure nothing is between the air conditioner
and the remote control that could block the
signal.
Make sure battery is fresh and installed correctly
as indicated on the remote control.
Cool Mode
Use the Cool mode at Low, Med, High or Auto
Speed for cooling. Use the Temperature Increase ▲
/ Decrease ▼ pads to set the desired temperature
between 61°F and 86°F in 1°F increments.
An electronic thermostat is used to maintain the room
temperature. The compressor will cycle on
and off to keep the room at the set level of comfort.
Set the thermostat at a lower number and the indoor
air will become cooler. Set the thermostat at a higher
number and the indoor air will become warmer.
NOTE: If the air conditioner is off and is then turned on
while set to a Cool setting or if turned from a fan
setting to a Cool setting, it may take approximately
3 minutes for the compressor to start and cooling to
begin.
Cooling Descriptions
For Normal Cooling³Select the Cool mode and
High or Med fan with a middle set temperature.
For Maximum Cooling³Select the Cool mode
and High fan with a lower set temperature.
For Quieter and Nighttime Cooling³Select the
Cool mode and Low fan with a middle set
temperature.
Energy Saver Mode
Controls the fan.
ON³The fan will cycle on and off with the
compressor. This results in wider variations of room
temperature and humidity. Normally used when the
room is unoccupied. NOTE: The fan may continue to
run for a short time after the compressor cycles off.
Fan Only Mode
Use the Fan Only Mode at Low, Med or High fan
speed to provide air circulation and filtering without
cooling. Since fan-only settings do not provide
cooling, a Set temperature cannot be entered. The
room temperature will appear
in the display.
Auto Mode
Set to Auto for the fan speed to automatically set
to the speed needed to provide optimum comfort
settings with the set temperature.
If the room needs more cooling, the fan speed
will automatically increase. If the room needs less
cooling, the fan speed will automatically decrease.
OFF³The fan runs all the time, while the compressor
cycles on and off.

Care and cleaning of the air conditioner.
Grille and Case
Turn the air conditioner off and remove the plug from
the wall outlet before cleaning.
Air Filter
The air filter behind the front grille should be checked
and cleaned at least every 30 days or more often if
necessary.
To clean, use water and a mild detergent. Do not use
bleach or abrasives.
To remove:
Open the inlet grille by pulling downward on the tabs
at the top upper corners of the inlet grille until the
grille is in a 45º position. Remove the filter.
Clean the filter with warm, soapy water. Rinse and let
the filter dry before replacing it. Do not clean the filter
in a dishwasher.
CAUTION: DO NOT operate the air
conditioner without a filter because dirt and lint will
clog it and reduce performance.
Outdoor Coils
The coils on the outdoor side of the air conditioner
should be checked regularly. If they are clogged with
dirt or soot, they may be professionally cleaned.
How to Insert the Battery in the Remote Control
Remove the battery cover by twisting it
1
according to the arrow direction. A coin can be
used to twist the cover.
Insert new battery, making sure that the (+) and
2
(–) of battery are installed correctly.
NOTES:

ELECTRICAL REQUIREMENTS
Some models require a 115/120-volt AC,
60-Hz grounded outlet protected with a
15-amp time-delay fuse or circuit breaker.
The 3-prong grounding plug minimizes the
possibility of electric shock hazard. If the wall outlet
you plan to use is only a 2-prong outlet, it is your
responsibility to have it replaced with a properly
grounded 3-prong wall outlet.
Some models require 230/208-volt AC,
protected with a time-delay fuse or circuit
breaker. These models should be installed on
their own single branch circuit for best
performance and to prevent overloading
house or apartment wiring circuits, which
could cause a possible fire hazard from
overheating wires.
