PrecautionsSamsung Electronics 51-4 Precautions for handling a system containing refrigerantsAll system containing refrigerants shall be removed under regional regulations prior to the disposal toprevent the potential health and environmental consequences. Harmful for human body– When emitted liquid refrigerant contacts human body, contacted area may get frostbite, blister or become numb.If refrigerant leaks in airtight area, lack of oxygen may cause suffocation. When refrigerant is heated, it may generate harmful gas. Precautions for handling container– Do not apply shock or heat to the refrigerant container.1-5 Precautions for the brazing Clear any dangerous or inflammable materials in surrounding environment. Make sure to empty the remaining refrigerant in the product or pipe before brazing.– Brazing with the refrigerant still remaining in the product or pipe may cause poor result and generate harmful gas. Furthermore,pressure of the refrigerant may increase and cause damage to the leaking part. This may lead harmful refrigerant and oil to spurtout which can be dangerous for service personnel. Use nitrogen gas to get rid of the oxide forming during brazing.– Using other type of gas may cause damage to the product or the exterior.1-6 Precautions for charging refrigerants Add quantity of the refrigerant using a scale and perform a test operation with S-net.– Product performance may decrease if you add excessive amount of refrigerant. Do not charge refrigerants while heating the container up.– The container may get damaged by the heat and result in explosions. Do not operate the product without pressure switch(for product protection) and sensor.– If there are any internal blockage, high refrigerant pressure increase may damage the product or exterior.
