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.
Be cautious of file names like "Product Manual.pdf" that do not specifically state in the metadata. Many generic manuals for "stone carving" or "cutting machines" (as seen in some PDF search results) will appear when search engines look for "L68" numbers, but they are unrelated to refrigeration.
Technical Overview of the Donper L68WU1 R290 Refrigeration Compressor l68wu1 compressor pdf
1/3 HP (approximately 180W standard power consumption).
The internal system is charged with specialized, hygroscopic polyolester (POE) or synthetic oil approved by Donper. Do not add, drain, or mix standard mineral oils into the system. Doing so degrades the winding insulation and causes mechanical seize-up. Before mounting the new compressor, the existing system
Having an L68WU1 compressor PDF can be beneficial for several reasons:
