Please refer to the attached “Installation data” for graphs and numerical values in other cases.
پ
For units to which the Shut-off Valve unit (24 HP type) is connected and the system refrigerant amount exceeds
30 kg, the following restrictions shall be set on the main pipe length on the outdoor unit side of the Shut-off
Valve unit.
(Main piping length on the outdoor unit side of the Shut-off Valve unit)
≥
(total system refrigerant amount - 30 kg) × 3 m
If the main pipe length exceeds 40 m, it will not be restricted beyond that.
