Prior to Operation

Prior to Operation

PreparingforOperation

1.Contact an installation specialist for installation.

2.Plug in the power plug properly.

3.Use a dedicated circuit.

4.Do not use an extension cord.

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

6.If the cord/plug is damaged, replace it with only an authorized replacement part.

Usage

1.Being exposed to direct airflow for a long time may be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for a long time.

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

3.Do not use this air conditioner for non-specifiedspecial purpose (e.g. preserving precision devices, food, pets, plants, or art objects). Such use may damage your properties.

CleaningandMaintenance

1.Do not touch the metal parts of the unit when removing the filter. Injury can occur.

2.Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to 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 triggered while cleaning inner parts of the unit.

Service

For repair and maintenance, contact your authorized service dealer.

• This appliance must be properly grounded.

ENGLISH

 

To minimize the risk of electric shock, you must alway plug into a grounded oulet.

 

 

 

• Do not cut or remove the grounding prong from the power plug.

 

 

• 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.

 

 

• If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle and

 

 

circuit checked by a qualified electrician.

We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections,

 

use only a UL-listedadapter, 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.
