Refrigerant Piping Connection
When connecting refrigerant piping, do not let substances or gases other than the speci ed
refrigerant enter the unit. The presence of other gases or substances will lower the unit' s capacity,
and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and
injury.
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 5 meters.
A minimum pipe run of 3 metres is required to minimise vibration & excessive noise.
Refer to the table below for specifications on the maximum length and drop height of piping.
