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) to minimise
vibration & excessive noise.
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.

≥ 24,000 and < 36,000
Be extra careful not to damage, dent, or
deform the pipe while cutting. This will
drastically reduce the heating efficiency of the
unit.
