[Branch pipe set : DIS-WA1]
When 40-60 models of indoor units are applied to this combination, the
reducer 3 supplied with the branch piping set should be used in order to
reduce the liquid piping size from ø9.52mm to ø6.35mm at indoor unit side
(flare connection). Accordingly be sure to select the liquid piping size
ø9.52mm from branch to indoor unit.
The reducer 4 is for FDC71 and 100 models only.
