The length of refrigerant piping will aect the performance and energy eciency of the unit. Nominal
eciency 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 specications on the maximum length and drop height of piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and are them properly. This will ensure
