7.1 Preparing refrigerant piping

7.1.1 Refrigerant piping requirements

INFORMATION

Also  read  the  precautions  and  requirements  in  the 

"2  General  safety

precautions"

 [

4

 7].

CAUTION

Piping and joints of a split system shall be made with permanent joints when inside
an occupied space except joints directly connecting the piping to the indoor units.

NOTICE

The piping and other pressure-containing parts shall be suitable for refrigerant. Use
phosphoric acid deoxidised seamless copper for refrigerant.

Foreign  materials  inside  pipes  (including  oils  for  fabrication)  must  be
≤30 mg/10 m.

Refrigerant piping diameter

Use the same diameters as the connections on the outdoor units:

Pipe outer diameter (mm)

Liquid piping

Gas piping

Ø6.4

Ø9.5

Refrigerant piping material

Piping material:

 Phosphoric acid deoxidised seamless copper.

Flare connections:

 Only use annealed material.

Piping temper grade and thickness:

Outer diameter (Ø)

Temper grade

Thickness (t)

(a)

6.4 mm (1/4")

Annealed (O)

≥0.8 mm

t

Ø

9.5 mm (3/8")

Annealed (O)

(a)

Depending on the applicable legislation and the maximum working pressure of the unit
(see "PS High" on the unit name plate), larger piping thickness might be required.
