• When using the conventional flare tool, to connect R410A pipes with flaring, make a margin approx. 0.5 mm
longer than that of an R22 pipe so that the flare size matches the one specified. It is convenient to use a copper

• The flared supplied attachment pipe (Ø19.1) must be used to connect with discharge-side gas pipe (Ø19.1) of
MAP120 and MAP140. Do not use half hard or hard materials instead of the supplied attachment pipe. The half
hard or hard materials may be cracked and may cause leakage of refrigerant when it is flared.
• Use the flare nut provided with the product.
• After flaring the connection, be sure the flared part is not damaged, deformed, uneven, or flattened, and that
there are no cutting chips on it.
