Flexible pipework
- Allowable pipework length:
- L1:
- Maximum pipe run:
- Actual length = 120 m (MAX LENGTH)
- Equivalent length = 140 m (MAX LENGTH)
- L2-L3:
- Difference between maximum length and minimum length from the first distribution joint = 40 m (MAX LENGTH)
- L3 L4 Ln:
- Maximum length of each distribution joint= 30 m (Max length)
- L1+L3+L4:
- Maximum total pipe run length = 150 m (Max length)
- Allowable height difference:
- H1:
- When outdoor unit installed higher = 50 m (Max length)
- When outdoor unit installer lower = 40 m (Max length)
- H2:
- Maximum difference between indoor units = 15 m (Max length)
