Selection of piping dimensions
Select refrigerant branching dimensions between outdoor units and valve box, between valve box and indoor units
according to the following connection examples 1 and 2 and Tables 1-3.
Connection example 1: Connect an indoor
unit to the downstream of the valve box
Connection example 2: with branching in the
downstream of the valve box
(
) For dimensions of the pipes to the downstream of the valve box, see the table 3. Use the attached pipes for
connection in the way shown in Pipe connection according to the pipes dimensions and diameters for indoor unit
connection selected in Table 2.
