• It is not sanitary and could
cause illness or personal
injury hazard.

BeforeOperation

1. Plug in the power cord properly.

2. Use a dedicated circuit. Overloading the line could create a fire hazard.

3. Do not use an extension cord. See page 11 for more details.

4. Do not start/stop operation by plugging/unplugging the power cord.

5. If the power cord is damaged and requires replacement, have an Authorized
Servicer install an exact replacement part.

1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time.

2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.

3. Do not use this air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
could damage the items.

4. The air conditioner is a consumer comfort appliance, not a precision climate

control system.

1. Do not touch the metal parts of the unit when removing the filter. Injudes can
occur when handling sharp metal edges.

2. Do not use water to clean inside the air conditioner. Exposure to water can
destroy the insulation, leading to possible electric shock.

3. When cleaning the unit, first make sure that the power and breaker are turned
off. The fan rotates at a very high speed during operation. There is a

possibility of injury if the unit's power is accidentally triggered on while
cleaning inner parts of the unit.

For repair and maintenance, contact an Authorized Service Center. See the
warranty page for details or call [phone]. Have your model number and
serial number available. They should be written on page 2 of this manual.

ELECTRICAL SAFETY

IMPORTANT GROUNDING INSTRUCTIONS

Air conditioner has a three-prong grounding plug on its power supply cord, which must be plugged into
properly grounded three-prong wall receptacle for your protection against possible shock hazard.

Owner's Manual 9

ElectricalSafety

WARNING: This appliance must be properly grounded.

The power cord of this appliance is equipped with a three-prong grounding plug.
To minimize the risk of electric shock, use the plug with a standard three=slot
grounding wall power outlet. If the power outlet does not include a grounding slot,
have a qualified electrician replace the outlet before you use the room air

conditioner.

WARNING: Changing the outlet without making the appropriate wiring

changes will create an unsafe condition that could result in fire or
electrical shock. Refer all such work to a licensed and qualified

electrician.

Preferred method

Ensure proper ground

exists before use

WARNING: Do not cut or remove the grounding prong from the power

plug.

WARNING: Attaching the adapter ground terminal to the wall

receptacle cover screw does not ground the appliance unless the
cover screw is metal and not insulated, and the wall receptacle is

grounded through the house wiring.

WARNING: if you have any doubt whether the air conditioner is

&

properly grounded, have the waft receptacle and circuit checked by a

qualified electrician.

10 Room Air Conditioner

ElectricalSafety

We strongly discourage the use of an adapter due to potential safety hazards.

For temporary connections, use only a UL-listed adapter, available from most
local hardware stores. Ensure that the large slot in the adapter is aligned with

the large slot in the receptacle for a proper polarity connection.

To disconnect the power cord from the adapter, use one hand on each to avoid

damaging the ground terminal. Avoid frequently unplugging the power cord as

this can lead to eventual ground terminal damage.
