Appendix:
1.Standard length of connection pipe
● 5m, 7.5m, 8m.
2.Min. length of connection pipe is 3m.
3.Max. length of connection pipe and max. high difference.(More details please refer to the specifications)
4.The additional refrigerant oil and refrigerant charging required after prolonging connection pipe
● After the length of connection pipe is prolonged for 10m at the basis of standard length, you should add 5ml of refrigerant oil
for each additional 5m 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
