Read Before Installation Piping Materials Types of Copper Pipes Reference Maximum Operation Pressure Applicable Refrigerants 3 4MPa R22 R407C 4 3 MPa R32 Use pipes that meet the local standards Piping Materials Radial Thickness Use pipes made of phosphorus deoxidized copper Since the operation pressure of the units that use R32 is higher than that of the units for use with R22 use pipes with at least the radial thickness specified in the chart below Pipes with a radial thickness of 0 7mm or less may not be used 06 35 Size mm Size inch 1 4 Radial Thickness mm 0 8t 09 52 3 8 0 8t 012 7 1 2 0 8t 015 88 5 8 1 0t 019 05 3 4 1 0t Type Type 0 pipes Type 1 2H or Hpipes Although it was possible to use type 0 for pipes with a size of up to 0 19 05 3 4 with conventional refrigerants use type1 2H pipes for units that use R32 Type 0 pipes may be used if the pipe size is 019 05 and the radial thickness is 1 2t The table shows the standards in Japan Using this table as a reference choose pipes that meet the local standards Flare Machining type 0 and OL only The flare machining dimensions for units that use R32 is larger than those for units that use R22 in order to increase air tightness Flare Machining Dimension mm Dimension A External dimension of pipes Size 6 35 1 4 9 52 12 7 15 88 19 05 R32 R22 9 1 9 0 3 8 13 2 13 0 1 2 16 6 16 2 5 8 19 7 19 4 3 4 24 0 23 3 S Ij 1 If a clutch type flare tool is used to machine flares on units that use R32 make the protruding part of the pipe between 1 0 and 1 5mm Copper pipe gauge for adjusting the length of pipe protrusion is useful Flare Nut Type 2 flare nuts instead of type 1 nuts are used to increase the strength The size of some of the flare nuts have also been changed Flare nut dimension mm External dimension of pipes Size Dimension B R32 Type2 R22 Type1 6 35 1 4 17 0 17 0 9 52 3 8 1 2 22 0 22 0 12 7 26 0 24 0 15 88 5 8 29 0 27 0 19 05 3 4 36 0 36 0 Dimension B The table shows the standards in Japan Using this table as a reference choose pipes that meet the local standards 18
