Elias sat up, his joints popping. He pointed at the side of the machine, where a yellowed sticker was peeling off the metal casing. The text was faded, barely legible under years of accumulated dust.
Before mounting the new compressor, the existing system must be in perfect condition. This includes flushing the system to remove any debris or old oil, replacing the filter drier, and pressure testing all components for leaks.
All brazing operations must be performed with a continuous flow of an inert gas, like nitrogen, through the system. This prevents the formation of copper oxide (scale) inside the tubing, which can contaminate the oil and cause a compressor burnout. Brazing should be done with a containing a high concentration of silver (e.g., 15% or 45%). The low-carbon steel process tube should be brazed using a flux-coated rod or one with 2% to 5% silver ; do not use copper-phosphorus rods on steel as they will not bond properly. l68wu1 compressor pdf
Ensure evaporating temperatures fall within the -35°C to -10°C (-31°F to 14°F) window.
