Prior to Operation
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.
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.
Cleaning and Maintenance
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.

Introduction
Temporary Use of an Adapter
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.
Temporary method
Adapter Plug
Metal Screw
Receptacle Cover
WARNING: Never use the appliance with a broken adapter.
Temporary Use of an Extension Cord
We strongly discourage the use of an extension cord due to potential safety hazards. For temporary situations, use only CSA certified and UL listed 3-wire grounded extension cords, rated 15 A, 125 V.
