Caution:
1. The standard Pipe length is 7.5m, 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.
