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 0.0013gal 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):
● Basing on the length of standard pipe, add refrigerant according to the requirement as shown in the table. 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
Additional refrigerant charging amount for R22, R407C, R410A and R134a
