Precautions For Handling Refrigerant Of The Dvm Chiller; Precautions For Welding The Dvm Chiller Pipe - Samsung AG042KSVANH Service Manual

1-4. Precautions for Handling Refrigerant of the DVM CHILLER

Environmental Cautions: Air pollution due to gas release
Safety Cautions
If liquid gas is released, then body parts that come into contact with it may experience frostbite/blister/numbness.
If a large amount of gas is released, then suffocation may occur due to lack of oxygen. If the released gas is heated, then noxious gas may be
produced by combustion.
Container Handling Cautions
Do not subject container to physical shock or overheating. (Flowage is possible while moving within the regulated pressure.)
1-5. Precautions for Welding work the DVM CHILLER Pipe
Dangerous or flammable objects around the pipe must be removed before the welding.
If the refrigerant is kept inside the product or the pipe, then remove the refrigerant prior to welding.
If the welding is carried out while the refrigerant is kept inside, the welding cannot be properly performed. This will also produce noxious
gas that is a health hazard. This leakage will also explode with the refrigerant and oil due to an increase in the refrigerant pressure, posing a
danger to workers.
Please remove the oxide produced inside the pipe during the welding with nitrogen gas.
Using another gas may cause harm to the product or others.
