1. SAFETY CONSIDERATIONS
Read these “SAFETY CONSIDERATIONS for Installation” carefully before installing air conditioning equip-
ment. After completing the installation, make sure that the unit operates properly during the startup operation.
Instruct the customer on how to operate and maintain the unit. Inform customers that they should store this
Installation Manual with the Operation Manual for future reference.
Always use a licensed installer or contractor to install this product. Improper installation can result in water or
refrigerant leakage, electrical shock, fire, or explosion.
Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols:
DANGER ........... Indicates an imminently hazardous situation which, if not avoided, will result in death
or serious injury.
WARNING ......... Indicates a potentially hazardous situation which, if not avoided, could result in death
or serious injury.
CAUTION .......... Indicates a potentially hazardous situation which, if not avoided, may result in minor
or moderate injury. It may also be used to alert against unsafe practices.
NOTE................. Indicates situations that may result in equipment or property-damage accidents only.
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 in contact with fire. 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 flammable materials are present due to risk of explosions that can cause
serious injury or death.
