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.
• If refrigerant gas leaks during installation, ventilate the
area immediately. Refrigerant gas may produce toxic gas
if it comes into contact with re. Exposure to this gas could
cause severe injury or death.
• After completing the installation work, check that the
refrigerant gas does not leak throughout the system.
• Do not install unit in an area where ammable materials
are present due to risk of explosions that can cause
serious injury or death.
• Safely dispose all packing and transportation materials
in accordance with federal/state/local laws or ordinances.
Packing materials such as nails and other metal or
wood parts, including plastic packing materials used for
transportation may cause injury or death by suffocation.
• All possible ignition sources, including cigarette smoking,
should be kept sufciently far away from the site of
installation, repairing, removing and disposal.
