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 non­specified special purpose (e.g. preserving
