Note on Pipe Length
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 16.5ft. In North America, standard pipe length is 25'.
A minimum pipe run of 10 feet is required to minimize vibration & excessive noise. Refer to the table
below for specifications on the maximum length and drop height of piping
