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.
●
If the reducer packaged with the unit is used, it should be brazed on site.
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.
●
The cut should be made as far away from the internal dowel as possible.
●
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).
