1.1 Warnings and Cautions Regarding Safety of Workers
This manual is for the
person in charge of
maintenance and
inspection.
Warning
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.
