• Header should be insulated with the insulator in each kit.
• Joints between branch and pipe should be sealed with the tape in-
cluded in each kit.
• Any cap pipe should be insulated using the insulator provided with
each kit and then taped as described above.
as shown in the figure.
[unit:mm]
• When the number of indoor units to be connected to the branch
pipes is less than the number of branch pipes available for connec-
tion then cap pipes should be fitted to the surplus branches.
• Fit branch pipe lie in a horizontal plane.
Ⓐ To Branch Piping or Indoor Unit
Ⓑ To Outdoor Unit
• Ensure that the branch pipes are attached horizontally or vertically
(see the diagram below.)
• There is no limitation on the joint mounting configuration.
• If the diameter of the refrigerant piping selected by the procedures
described is different from the size of the joint, the connecting sec-
tion should be cut with a pipe cutter.
• Branch pipe should be insulated with the insulator in each kit.
Ⓐ To Outdoor Unit
Ⓑ To Indoor Unit
• The indoor unit having larger ca-
pacity must be installed closer
to Ⓐ than smaller one.
• If the diameter of the refrigerant
piping selected by the proce-
dures described is different
from the size of the joint, the
connecting section should be
cut with a pipe cutter.
ⓒ Pipe cutter
• When the number of pipes to be
connected is smaller than the
number of header branches, in-
stall a cap to the unconnected
branches.
