Sample:
AMCF-H09/4R1Actual Pipe length is 25 meters, Gas pipe diameter is 9.52
mm. If there’s 5 bends and
2 oil loops during the installation, then the equivalent pipe length should be:
L=25+0.18×5+1.3×2=28.5(m)

Caution:
1. The standard Pipe length is 5m, if the pipe length is less than this then no additional charging is
necessary. If the pipe length is more than this then you should charge more refrigerant into the system
according to the above Charging Data
2. The thickness of the pipe is 0.6-1.0, bearing pressure is 4.2MPa;
3. If the connection pipe is too long, the cooling capacity and stability would be decreased. And the
more bend quantity, the resistance in the piping system would be bigger, then the cooling and heating
capacity would be decreased even lead to compressor broken. We suggest you to use the shortest
connection pipe according to the pipe length parameter in this manual.If the height difference between
outdoor and indoor unit is more than 5m, an oil trap should be installed in the gas pipe for every 10
meters.
