IMPORTANT SAFETY INFORMATION
READ ALL SAFETY INFORMATION
BEFORE USING
•This air conditioner must be
properly installed in accordance
with the Installation Instructions
before it is used.
•Repair or replace immediately
all electric service cords that have
become frayed or otherwise
damaged.
•Turn the selector control to
OFF
and unplug your air conditioner
before making any repairs.
NOTE: We strongly recommend
that any servicing be performed by
a qualified individual.
Because most 2-prong outlets are
not grounded, we strongly advise
against using an adapter plug.
However, a temporary connection
may be made where local codes
permit and if the 2-prong wall out-
let is properly grounded.
When you plug the adapter in,
make sure the larger prong goes
into the larger slot to provide the
proper polarity for the power cord.
FOR PROPER GROUNDING:
1 Screw the adapter to the outlet,
using the outlet cover screw.
2 Ground the outlet through the house
wiring.
When disconnecting the power
cord from the adapter, hold the
adapter close to the outlet while
pulling the plug out. If this is not
done, the grounding connector is
likely to break with repeated use.
If the grounding connector breaks,
DO NOT USE the air conditioner
until a proper ground has again
been made.
Adapter Plug 115V
This is a temporary method.
UL-listed adapters are avail-
able at most hardware stores.
The use of an extension cord is not
recommended. However, if an
extension cord is required to reach
the nearest wall receptacle, use only
a UL-listed, 3-wire, grounded, 14
gauge, 15A, 125V appliance exten-
sion cord.
CAUTION:
DO NOT use an extension cord with
any of the 208/230-volt models.
Extension Cord 115V

The temp control is used to maintain the
room temperature. The compressor will cycle
on and off to keep the room at the same level
of comfort. When you turn the knob to
COOLER
(blue) the indoor air will become cooler. Turn
the knob to
WARMER (red) and the indoor air
will become warmer.
HEAT PUMP MODELS
When the outdoor temperature is lower than
25°F., heat is provided by the electric heater in
the air conditioner instead of by the heat pump.
HIGH COOL and LOW COOL provide cooling with
different fan speeds.
HIGH HEAT and LOW HEAT provide heating with
different fan speeds.
LOW FAN or HIGH FAN provides air circulation
and filtering without cooling or heating.
NOTE:
If you move the switch from a cool or heat setting
to OFF or to a fan setting, wait at least 3 minutes
before switching back to a cool or heat setting.
A 3-minute delay is automatically provided on the
Heat/Cool and Heat Pump models.

Operating Instructions
Care & Cleaning
Turn the air conditioner off and
remove the plug from the wall out-
let before cleaning.
To clean, use water and a mild
detergent. Do not use bleach or
abrasives.
Grille and Case
The coils on the outdoor side of
the air conditioner should be
checked regularly. It is necessary to
remove the air conditioner from
the wall case to inspect them. Dirt
build-up occurs on the surface
which is not visible from the out-
side. If they are clogged with dirt or
soot it will reduce the cooling or
heating performance and the unit
will not work properly.
They may be professionally steam
cleaned, a service available
through your GE service outlet.
Outdoor Coils

The front grille can be removed
for more thorough cleaning or
to make the model and serial
numbers accessible.
To remove:
Pull out from the bottom and lift
up from the tabs on the top of the
case.
To replace:
Hook the tabs on the front grille
even with the tabs on the front of
the case and snap into place.

Turn the air conditioner off before
cleaning.
The most important thing you can
do to maintain the air conditioner
is to clean the filter at least every 30
days. Clogged filters reduce cool-
ing, heating and airflow.
Keeping the filter clean will:
•Decrease cost of operation.
•Save energy.
•Prevent clogged heat exchanger
coils.
•Reduce the risk of premature
component failure.
To clean the air filter:
•Vacuum off the heavy soil.
•Run water through the filter
from the back side.
•Dry thoroughly before replacing.
On some models, carefully pull the
tab forward, up and out.
On other models, pull it down.
Replace the clean filter by pushing
it back into place.
CAUTION:
DO NOT operate the air conditioner
without the filter in place. If a filter
becomes torn or damaged it should
be replaced immediately.
Operating without the filter in
place or with a damaged filter will
allow dirt and dust to reach the in-
door coil and reduce the cooling,
heating, airflow and efficiency of
the unit.
Replacement filters are available
from your salesperson, GE dealer,
GE Service and Parts Center
or authorized Customer Care®
servicers.

•The satisfactory operation of this air condition-
er is dependent upon it being installed in a wall
case, and used with an exterior grille, both
specifically designed for use with this unit. Use
with an incorrect wall case or with an incorrect
grille may result in poor performance and
could cause damage to the unit. If you are not
sure if you have the correct wall case and the
rear grille please contact the company where
you purchased the unit.
•For personal safety, this air conditioner must be
properly grounded.
•It is important to have the wall outlet and circuit
checked by a qualified electrician if there is any
doubt as to whether a proper ground exists.
•Follow National Electrical Code (NEC) or local
codes and ordinances.
CAUTION:
• Do not, under any circumstances, cut or remove
the third (ground) prong from the power cord.
• Do not change the plug on the power cord of this
air conditioner.
• Aluminum house wiring may present special
problems—consult a qualified electrician.
We recommend that the 230/208-volt, 60 Hz
models be installed on their own single branch
circuit supplying 230/208-volt a.c., protected
with a time delay fuse or circuit breaker.
PPaarraalllleellPPeerrppeennddiiccuullaarrTTaannddeemm
115V. 230/208V. 230/208V.
15 Amp. 20 Amp. 15Amp.
This is recommended for best performance and
to prevent overloading house or apartment
wiring circuits, which could cause a possible fire
hazard from overheating wires.
The 115-volt models require a 115/120-volt a.c.,
60 Hz grounded outlet protected with a 15-amp
time delay fuse or circuit breaker.
The 3-prong grounding plug minimizes the possi-
bility 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.

Installing a J-Model in an Existing Wall Case
9
J-model air conditioners may fit in existing wall
cases. However, they often need a kit to properly
adapt the case to the GE air conditioner. Answer
these questions and see the chart below for the
proper kit.
1What brand air conditioner will you be replacing?
2 What are the dimensions of the wall case
currently in use?
3 What is the model number of the chassis currently
in use? What is the model (or Type) number of the
wall case currently in use?
Frequently, the J-model adapter kit will apply to
another brand model “series” or specific vin-
tage. In these cases, you need the chassis model
number and/or the wall case or “type” number
to confirm the use of the correct adapter kit.
4What type of outdoor grille is used with the cur-
rent wall case?
There may be an architectural grille attached
to a wall case to enhance the exterior appear-
ance of the building. Custom grilles may be
used with J-model wall cases provided a J-model
adapter kit is also used to ensure proper
airflow.
IMPORTANT!
GE strongly recommends the removal of the
old wall case and the installation of a new
GE Wall Case. If you decide to keep the exist-
ing wall case, you may need a kit to ensure
proper performance. If you DO NOT use a kit,
you run the risk of poor performance or
product failure. This is not covered under
the terms of the GE warranty.
