5. If the power cord is damaged and requires replacement, have an Authorized
Servicer install an exact replacement part.
1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
could damage the items.
4. The air conditioner is a consumer comfort appliance, not a precision climate
control system.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can
