A few pictures from a 3 pipe VRF system I piped in a couple years ago. 1000’+ of piping and the only fittings used were elbows on my 1 1/8” line as my bender only bends up to 7/8”. Isolation valves were also added as per manufacturers instructions for each branch line to solenoid control box. Everything here was field bent using hard drawn copper. Piping was annealed prior to bending and swaging of pipe to complete this job. This is a Sanyo (now Panasonic) ECO i 3way VRF system.
