Using a tube cutter cut the joints at the diameter required to match the outside diameter of the tubing you are connecting This is usually done at the installation site The tube diameter depends on the total capacity of the outdoor unit Note that you do not have to cut the joints if it already matches the tubing end size For size selection of the tube diameter refer to the installation instructions provided with the outdoor unit Avoid forceful cutting that may harm the shape of the joints or tubing Inserting the tubing will not be possible if the tube shape is not proper Stopper boss Cutting point e Cut off as far away from stopper as possible e After cutting the joints be sure to remove burrs on the inside of the joints If the joints have been squashed or dented badly reshaped them using a tube spreader Make this as long as Make sure there is no dirt or other foreign substances inside the distribution possible joint Insertion length of the connecting tube 2 47 Design of 3WAY VRF SYSTEM 7 Optional Parts The distribution joint can be either horizontal or vertical In the case of horizontal the L shaped tubing must be slanted slightly upward 15 to 90 Direction of Distribution Joint 15 to 30 upward slant Outdoor unit Outdoor Outdoo
