Prior to Operation

Preparing for Operation

1.Contact an installation specialist for

installation.

2.Plug in the power plug properly.

3.Use a dedicated circuit breaker.

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 specified special purpose (e.g. preserving precision devices, food, pets, plants, or art objects). Such use may damage your properties.

Components

Cleaning and Maintenance

1.Do not touch the metal parts of the unit

when removing the filter injury may 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 circuit 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.
