DANGER
• Refrigerant gas 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.
• If the refrigerant gas leaks during installation, ventilate the
area immediately.
Refrigerant gas may produce a toxic gas if it comes
in contact with fire such as from a fan heater, stove or
cooking device.
Exposure to this gas could cause severe injury or death.
• After completing the installation work, check that the
refrigerant gas does not leak.
Refrigerant gas may produce a toxic gas if it comes
in contact with fire such as from a fan heater, stove or
cooking device.
Exposure to this gas could cause severe injury or death.
• 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.
