<Piping Materials/Radial Thickness>

Use pipes made of phosphorus deoxidized copper.

Since the operation pressure of the units that use R410A 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.)

*Although it was possible to use type-O for pipes with a size of up to 19.05(3/4") with conventional refrigerants, use type-1/2H pipes for units that use R410A.(Type-O pipes may be used if the pipe size is 19.05 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-O and OL only)>

The flare machining dimensions for units that use R410A is larger than those for units that use R22 in order to increase air tightness.

If a clutch type flare tool is used to machine flares on units that use R410A, 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 s are used to increase the strength. The size of some of the flare nuts have also been changed.
