Required Tools/Equipment and Precautions for Use
Prepare the tools and equipment listed in the following table before starting installation work.
Newly prepared tools and equipment must be used exclusively.
Legend
: Prepared newly (Use for R410A only. Do not use for refrigerant R22 or R407C etc..)
: Conventional tools/equipment are available
Refrigerant Piping
New refrigerant (R410A)
When using the conventional piping kit
• When using the conventional piping kit that has no indication of applicable refrigerant types, be sure to
use it with a wall thickness of 0.8 mm for Ø6.4 mm, Ø9.5 mm, and Ø12.7 mm, and with a wall thickness
of 1.0 mm for Ø15.9 mm. Never 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, Ø9.5 mm, and Ø12.7 mm, and
with a wall thickness of 1.0 mm for Ø15.9 mm.
Never 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”
