2) Tighten the flare nuts with torque wrench until hearing “click” sound.
3) Use sponge to wrap the connecting pipe and joints without thermal insulation and tie it up
with plastic tape.
4) Mounting supporter for the connection pipe is required.
5) The bending degree of connection pipe should not be small too much, otherwise the pipe
might crack. Installation personnel should use tube bender when bending the pipe.
6) Don't pull of draw the pipe joints, otherwise indoor capillary or other pipes might be
damaged and even lead to refrigerant leakage.
4.3.2 Y-type manifold
(1) Y-type manifold
Fig.4.3.2
(2) Y-type manifold has several pipe sections with different pipe size, which is convenient to
match with various copper pipes. Use pipe cutter to cut in the middle of the pipe section with
different pipe size and eliminate the burr as well. Show as Fig.4.3.3.
(3) Y-type manifold should be installed vertically or horizontally.
