GEdoes 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. Ifyou 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 TESTbutton and
then the RESETbutton while plugged into the
outlet. If the TESTbutton does not trip or if the
RESETbutton 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.
