<Note>

• For pipe welding, do not use antioxidant, for its residue may cause tube blocking and component fault.

• For pipe welding, do not use flux. If the flux is chlorine product, it will corrode the tube; if it contains fluorine, it will

even cause detrimental effects to the refrigerant system, such as refrigerant oil deterioration. Please do not use

phosphor copper for welding material (BCup-2).

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 5-7.
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.
