Appendix 2: Configuration of Connection Pipe

1.Standard length of connection pipe
● 16.40ft, 24.61ft, 26.25ft.
2.Min. length of connection pipe is 9.84ft.
3.Max. length of connection pipe and max. high difference.
4.The additional refrigerant oil and refrigerant charging required after
prolonging connection pipe
● After the length of connection pipe is prolonged for 32.81ft at the
basis of standard length, you should add 5ml of refrigerant oil for each
additional 16.40ft of connection pipe.
● The calculation method of additional refrigerant charging amount (on
the basis of liquid pipe):
● When the length of connection pipe is above 16.40ft, add refrigerant according to the prolonged length of liquid pipe. The
additional refrigerant charging amount per meter is different according to the diameter of liquid pipe. See the following sheet.
● Additional refrigerant charging amount = prolonged length of liquid pipe X additional refrigerant charging amount per meter
