 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.
