2.2 Pipe length and drop height
The length of refrigerant piping will affect the performance and energy efficiency of the unit.
Nominal efficiency is tested on units with a pipe length of 5 meters (16.5ft). A minimum pipe run of
3 meters is required to minimize vibration & excessive noise.
Refer to the table below for specifications on the maximum length and drop height of piping.
