DANGER
Do not install unit in an area where fl ammable materials are •
present due to risk of explosion resulting in serious injury or
death.
Refrigerant is heavier than air and replaces oxygen. A •
massive leak could lead to oxygen depletion , especially in
basements, and an asphyxiation hazard could occur leading
to serious injury or death.
