DANGER
Do not ground units to water pipes, telephone wires or •
lightning rods because incomplete grounding could
cause a severe shock hazard resulting in severe injury or
death, and to gas pipes because a gas leak could result in
an explosion which could lead to severe injury or death.
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 gas is heavier than air and displaces oxygen. •
A massive leak could lead to oxygen depletion, especially in basements, and an asphyxiation hazard could
occur leading to serious injury or death.
If the refrigerant gas leaks during installation, ventilate •
the area immediately.
Refrigerant gas may produce toxic gas if it comes in contact
with fi re such as from a fan, heater, stove or cooking device.
Exposure to this gas could result in severe injury or death.
After completing the installation work, check that the •
refrigerant gas does not leak.
Refrigerant gas may produce toxic gas if it comes in contact
with fi re such as from a fan, heater, stove or cooking device.
