REFRIGERANT PIPING CONNECTION
When connecting refrigerant piping, do not let substances or gases other than the specified 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 (16.5ft)( In North America, the standard pipe
length is 7.5m (25')). A minimum pipe run of 3 metres is required to minimise vibration & excessive noise.
In special tropical area, for the R290 refrigerant models, no refrigerant can be added and the maximum
length of refrigerant pipe should not exceed 10 meters(32.8ft).
Refer to the table below for specifications on the maximum length and drop height of piping.

Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and flare them properly. This will ensure efficient
operation and minimize the need for future maintenance.
1. Measure the distance between the indoor and outdoor units.
2. Using a pipe cutter, cut the pipe a little longer than the
measured distance.
3. Make sure that the pipe is cut at a perfect 90° angle.
