When moving the equipment by hand, wear protective gloves to prevent
injuries.
Move or lift the equipment by holding its handles or lower edges. Do not hold
the handles of modules (such as power supply units, fans, and boards) that
are installed in the equipment because they cannot support the weight of the
equipment.
Avoid scratching the cabinet surface or damaging cabinet components and
cables during equipment transportation.
When transporting the equipment using a forklift truck, ensure that the forks
are properly positioned so that the equipment does not topple. Before moving
the equipment, secure it to the forklift truck using ropes. When moving the
equipment, assign dedicated personnel to take care of it.
Choose a road with good conditions or sea for transportation to ensure
equipment safety. Avoid tilt or jolt during transportation.
Move the cabinet with caution. Any bumping or falling may damage the
equipment.
At least two persons are required on a welding site.
A welder must have a work permit.
A welding site must be free from inflammables.
Ensure that a fire extinguisher, wet wiper, and water container are available.
A burning welding torch must not be placed on a component or on the floor,
and must not be placed in a metal container with acetylene and oxygen.
Otherwise, the gas may leak and cause a fire.
High-temperature pipes after welding must be promptly cooled.
Do not weld or cut on pressurized containers or pipes. Electric devices must be
powered off before welding.
When maintaining or replacing components, pay attention to high-
temperature components (such as the compressor, refrigerant pipe, and
electric heater) to prevent scalds.
When maintaining or replacing components, pay attention to high-pressure
components (such as the compressor and refrigerant pipe) to prevent the
refrigerant system from being cracked or exploded due to misoperations.
