For refrigerant charge purposes, consider only the liquid line; ignore the vapor line(s).
DANGER
• Refrigerant gas is heavier than air and replaces oxygen. A large leak, especially in enclosed spaces like basements, will result in oxygen
depletion, and an asphyxiation hazard will result in serious injury or death.
• If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas will result in producing toxic gas if it comes into
contact with fire. Exposure to this gas will result in severe injury or death.
WARNING
• Refrigerant cannot be charged until field wiring has been completed. Improper installation could result in physical injury and / or death.
• Refrigerant must only be charged after performing the leak test and the vacuum. Improper installation could result in physical injury and / or
death.
• When charging a system, take care that its maximum permissible charge is never exceeded. Improper installation could result in physical
injury and / or death.
• Charging with an unsuitable substance can cause explosions and accidents, so always ensure that the appropriate R410A refrigerant is
used. Improper installation could result in physical injury and / or death.
• Refrigerant cylinders must be opened slowly. Improper installation could result in physical injury and / or death.
• Always use protective gloves and eyewear when charging refrigerant. It could result in physical injury and / or death.
• When the refrigerant system is to be opened, refrigerant must be treated according to the applicable local, state, and federal codes. Improp-
er installation could result in physical injury and / or death.
• To avoid compressor breakdown,
do not charge the refrigerant more than the specified amount. Improper installation could result in
physical injury and / or death.
