Refrigerant Piping Connection

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). A minimum pipe run of 3 metres is
required to minimise vibration & excessive noise.
For special tropical area, the maximum length of refrigerant pipe should not exceed 10 meters(32.8ft)
and no refrigerant can be added(For R290 refrigerant models).
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. For R32/R290 refrigerant
models, the pipe connection points must be
placed outside of room.
1. Measure the distance between the indoor and
outdoor units.

≥ 15,000 and < 24,000
≥ 24,000 and < 36,000
≥ 36,000 and ≤ 60,000
2. Using a pipe cutter, cut the pipe a little longer
3. Make sure that the pipe is cut at a perfect 90°
