DANGER
• Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen
depletion, especially in basements, and an asphyxiation hazard could occur leading to serious
injury or death.
• Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete
grounding can cause a severe shock hazard resulting in severe injury or death. Additionally,
grounding to gas pipes could cause a gas leak and potential explosion causing severe injury or
death.
