Because of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle. Do not use pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries. Because the surface of the pipe is exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials, to prevent mistaken use. 3. Precautions during refrigerant piping work Take the following precautions on-site when connecting pipes. Please use a high temperature soldering iron. Such problems include insufficient insulation, problem with the power source, malfunction of a compressor and a fan. If this happen, remove the cover of the remote control and push the reset point once to clear the memory data. The non-numbered parts are not kept as standard service parts.
