Warnings and Cautions Regarding Safety of Workers

Do not store equipment in a room with fire sources (e.g., naked flames, gas
appliances, electric heaters).
Be sure to disconnect the power cable from the socket before disassembling
equipment for repair.
Working on 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 inspect
the circuits, do not touch any electrically charged sections of the equipment.
If refrigerant gas is discharged during repair work, do not touch the
discharged refrigerant gas.
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 refrigerant gas leaks during repair work, ventilate the area.
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.
