3. Long piping length
Cooling capacity (KBtu/h)
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.
