Warnings and Cautions Regarding Safety of Workers

Do not store the equipment in a room with successive fire sources (e.g.,
naked flame, gas appliance, electric heater).
Be sure to disconnect the power cable plug from the plug socket before
disassembling the equipment for repair.
Working on the equipment that is connected to the power supply may cause an
electrical shock.
If it is necessary to supply power to the equipment to conduct the repair or
inspecting the circuits, do not touch any electrically charged sections of the
equipment.
If the refrigerant gas is discharged during the repair work, do not touch
the discharged refrigerant gas.
The refrigerant gas may cause frostbite.
When disconnecting the suction or discharge pipe of the compressor at
the welded section, evacuate the refrigerant gas completely at a well-
ventilated place first.
If there is gas remaining inside the compressor, the refrigerant gas or
refrigerating machine oil discharges when the pipe is disconnected, and it may
cause injury.
If the refrigerant gas leaks during the repair work, ventilate the area.
The refrigerant gas may generate toxic gases when it contacts flames.
Be sure to discharge the capacitor completely before conducting repair
work.
The step-up capacitor supplies high-voltage electricity to the electrical
components of the outdoor unit.
A charged capacitor may cause an electrical shock.
