Refrigerant Piping
New refrigerant (R410A)
When using the conventional piping
•
When using the conventional piping with no indication of applicable refrigerant types, be sure to use it with a wall thickness
of 0.8 mm for Ø6.4 mm and Ø12.7 mm. Do not use the conventional piping kit with a wall thickness less than these
thicknesses due to insufficient pressure capacity.
When using general copper pipes
•
Use general copper pipes with a wall thickness of 0.8 mm for Ø6.4 mm and Ø12.7 mm.
Do not use any copper pipes with a wall thickness less than these thicknesses.
Flare nuts and flare machining
•
The flare nuts and flare machining are different from those for the conventional refrigerant.
Use the flare nuts supplied with the air conditioner or those for R410A.
•
Before performing flare machining, carefully read "REFRIGERANT PIPING".
