Equivalent length 13m
Maximum allowable height difference
H1 ≤50m (40m)
(if outdoor is located below indoor units)
Conditional extension up till 90m is possible without
additional option kit:
▪ In case the outdoor location is higher than indoor:
extension is possible up till 90 m and following
2conditions must be fulfilled:
▪ Liquid piping size up (see table "Size up" in "E: Piping
between refrigerant branch kit and indoor unit" on
page13).
▪ Dedicated setting on outdoor unit is required (see [2‑49]
in "7.2.8Mode 2: Field settings"on page35).
▪ In case the outdoor location is lower than indoor:
extension is possible up till 90 m and following
6conditions must be fulfilled:
▪ 40~60m: minimum connection ratio connected: 80%.
▪ 60~65m: minimum connection ratio connected: 90%.
▪ 65~80m: minimum connection ratio connected: 100%.
▪ 80~90m: minimum connection ratio connected: 110%.
▪ Liquid piping size up (see table "Size up" in "E: Piping
between refrigerant branch kit and indoor unit" on
page13).
▪ Dedicated setting on outdoor unit is required (see [2‑35]
in "7.2.8Mode 2: Field settings"on page35).
H2 ≤30m
H3 ≤5m
Maximum allowable length after branch
The pipe length from the first refrigerant branch kit to the indoor unit
≤40 m.
Example 1.1: unit 8: b+c+d+e+f+g+p≤40m
Example 1.2: unit 6: b+h≤40m, unit 8: i+k≤40m
Example 1.3: unit 8: i≤40m
