CAUTION!
The items to be followed are classified by the symbols:
1) Do not install without an authorized servicer/installer.
2) Install according to this installation instruction. If installation is defective, it can cause water leakage, or
electrical shock/fire.
3) Use the supplied accessories and specified parts for installation.
4) Install the indoor unit on a wall strong enough to hold the unit's weight. Install the outdoor unit on a
raised concrete pad or blocks to provide a solid, level foundation. In a location with high winds, anchor
the unit and provide an air baffle. In snowy areas (for heat pump models), install the outdoor unit on a
raised platform so that it is higher than drifting snow. Provide snow vents.
5) For electrical work, follow local and national electric codes and these installation instructions. An
independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defects
are found in electrical work, it will cause electrical shock or fire.
6) Use the specified cable and connect tightly and clamp the cable so that no external force will stress the
terminal. Loose wiring may cause overheating at the connection points and a possible fire hazard.
7) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board
cover is not fixed perfectly, it will cause overheating at connection point of terminal, fire or electrical shock.
8) When charging the unit, take care not to let air/substances other than the specified refrigerant go into
refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration
cycle, explosion and injury.
9) Do not modify the length of the power supply cord or use an extension cord, and do not share the
single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.
1) This equipment must be grounded and installed with a ground leakage current breaker. It may cause
electrical shock if grounding work doesn't comply with local/national electric codes.
2) Do not install the unit at place where leakage of flammable gas may occur. If gas leaks and
accumulates near the unit, it may cause fire.
3) Carry out drainage piping as mentioned in installation instructions. If not done correctly, water may
