(1) Points regarding branch piping construction

● Cut the component with a pipe cutter at the size/position corresponding to size of the on site piping, selected
based upon the total capacity of the indoor units. If the end size is the same as the on site pipe size, then it is
not necessary to cut the component.
Note Cut the component so as not to distort the pipe. (The connecting pipe may not be able to be inserted.) Refer
to the installation construction manual supplied with the outdoor unit for details of selecting the pipe size.
Cutting example
1)Cutting at a non-brazed position
Internal dowel
Note) The method of cutting at a location other
than where it has been brazed is the same
as cutting at a non-brazed position.
● After cutting, remove all burrs, and finish the end face correctly.
(If the pipe is badly bent or dented, use a tool to open the opening.)
● Check that there is no dirt or foreign matter inside the pipe branch.
● The pipe branch can be used horizontally or vertically (either pointing up or pointing down).
Used horizontally
Outdoor unit side
● Branch piping should be insulated with insulating material resistant to temperatures of 120
● For further details, refer to the installation construction manual.
: In this component there are positions where it has been brazed and those where it has been
processed to be continuous. The cutting position varies, so care is needed.
