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, ony replace it with 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.Ventilate the room when the air conditioner is used with other heating devices. Otherwise the oxygen supply may be inadequate.

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 power is accidently turned on while the interior of the unit is being cleaned.

The air conditioner is operating normally when:

•You hear a pinging noise. This is caused by water being picked up by the fan on rainy days or in highly humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency.

•You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid conditions or on rainy days. This water overflows and drips from the rear of the unit.

•You hear the fan running while the compressor is silent. This is a normal operational feature.
