When installing or relocating the unit, check that

equipment damage.
• If the wrong twinning pipe or wrong size connecting pipe is used,
air conditioning performance will suffer.
• If leaked refrigerant comes in contact with a heat source, such
as a fan heater, stove, or electric grill, toxic gases will be
generated.
• Improper installation may result in water leakage, electric shock,
or fire.
• Any presence of foreign substance or air can cause abnormal
pressure rise or explosion.
• During or immediately after operation, certain parts of the unit
such as pipes and compressor may be either very cold or hot,
depending on the state of the refrigerant in the unit at the time.
To reduce the risk of frostbites and burns, do not touch these
parts with bare hands.
• If refrigerant leaks and comes in contact with an open flame,
toxic gases will be generated.
Properly dispose of packing materials.
• Plastic bags can pose suffocation and choking hazards: keep
them out of the reach of children. Tear the plastics bags before
disposing of them.
