7.1 Preparing refrigerant piping

7.1.1 Refrigerant piping requirements

NOTICE

The piping and other pressure-containing parts shall be suitable for refrigerant. Use

phosphoric acid deoxidised seamless copper for refrigerant piping.

INFORMATION

Also read the precautions and requirements in the "2 General safety

precautions"[47].

▪ Foreign materials inside pipes (including oils for fabrication) must be

≤30mg/10m.

When connecting multiple indoor units to the outdoor unit, mind the following:

Refrigerant branch kit One or more refrigerant branch kits are required. See

"5.2.1Possible options for the outdoor unit"[423].

Upward and downward

piping

Perform upward and downward piping only on the

main piping line (L1).

Branch pipes ▪ Install the branch pipes horizontally (with a

maximum inclination of 15°) or vertically.

▪ Make the length of the branch pipes to the indoor

units as short as possible.

▪ Try to keep length of the branch pipes to the indoor

units equal.
