4.8 Pipe Flushing
4.8.1 Purpose
To remove dust, other particles and moisture, which could cause compressor malfunction if not flushed out before the
system is run, the refrigerant piping should be flushed using nitrogen. As described in Part 3, 4.1.1 “Installation procedure”,
pipe flushing should be performed once the piping connections have been completed with the exception of the final
connections to the indoor units. That is, flushing should be performed once the outdoor units have been connected but
before the indoor units are connected.
