6.2 Indoor Unit Connection



Indoor Unit connecting pipe from branch (a,b,c,d,e,f)

CAUTION

6.3 The amount of Refrigerant

The calculation of the additional charge should take into account the length of pipe and CF(correction Factor) value

of indoor unit.

Note

• * : For CF value (additional refrigerant) table of indoor units, please refer to PDB of indoor unit.

Indoor Unit capacity [kW(Btu/h)]

Liquid pipe [mm(inch)]

Gas pipe [mm(inch)]

5.6(19,100)

Ø6.35(1/4)

Ø12.7(1/2)

< 16.0(54,600)

Ø9.52(3/8)

Ø15.88(5/8)

• Bending radius should be at least twice the diameter of the pipe.
• Bend pipe after 500mm or more from branch(or header).

Do not bend U type.
It may cause Performance unsatisfactory or noise.
