Refrigerant piping diameter
The refrigerant piping diameters must comply with the following:
Piping Diameter
L1 (pair, twin, triple, double twin) See below.
L2,L3 (twin)
L2~L4 (triple)
L4~L7 (double twin)
Use the same diameters as the
connections (liquid, gas) on the indoor
units.
L2,L3 (double twin) Liquid piping: Ø9.5mm
Gas piping: Ø15.9mm

(a)
When installing new piping, use the same diameters as the connections on the outdoor
units (i.e. standard diameters for liquid and gas piping).
(b)
When reusing existing piping, you may use the size‑up or size‑down diameters, but then
capacity might decrease, and stricter piping length requirements are applicable. Assess
these limitations in relation to the complete installation.
Refrigerant piping length and height difference
The piping lengths and height differences must comply with the following requirements:
