DANGER
• Refrigerant gas is heavier than air and displaces oxygen. A massive leak can lead to oxygen depletion, especially in base-
ments, and an asphyxiation hazard could can occur leading to serious injury or death.
• If the refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce toxic gas if it
comes in contact with fire such as from a fan, heater, stove or cooking device. Exposure to this gas could result in severe
injury or death.
• After completing the installation work, check that the refrigerant gas does not leak. Refrigerant gas may produce toxic gas if
it comes in contact with fire such as from a fan, heater, stove, or cooking device, or other heat source. Exposure to this gas
can cause severe injury or death.
• Do not ground units to water pipes, telephone wires, or lightning rods because incomplete grounding can cause a severe
shock hazard resulting in severe injury or death. Do not ground units to gas pipes because a gas leak can result in an explo-
sion that can lead to severe injury or death.
• Safely dispose of the packing materials. Packing materials such as nails and other metal or wooden parts, may cause stabs
or other injuries. Tear apart and throw away plastic packaging bags so that children do not play with them. Children playing
with plastic bags face the danger of death by suffocation.
• Do not install unit in an area where flammable materials are present due to risk of explosions that can result in serious injury
WARNING
or death.
• Ask your dealer or qualified personnel to carry out installation work. Do not try to install the machine by yourself.
• Improper installation may result in water leakage, electric shocks, or fire.
• Perform installation work in accordance with this installation manual. Improper installation may result in water leakage, elec-
tric shocks, or fire.
• Be sure to use only the specified accessories and parts for installation work. Failure to use the specified parts may result in
water leakage, electric shocks, fire, or the unit falling.
• Install the electronic expansion valve unit on a foundation strong enough to withstand the weight of the unit. A foundation of
insufficient strength may result in the unit falling and causing injuries.
• Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by qualified
personnel according to local laws and regulations, and this installation manual. An insufficient power supply capacity or
improper electrical construction may lead to electric shocks or fire.
• Make sure that all wiring is secured, the specified wires are used, and that no external forces act on the terminal connections
CAUTION
or wires. Improper connections or installation may result in fire.
• When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the wires so that
the electric parts box lid can be securely fastened. Improper positioning of the electric parts box lid may result in electric
shocks, fire, or the terminals overheating.
• Before touching electrical parts, turn off the unit.
