Installation and Maintenance
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.
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):

● When the length of connection pipe is above 5m, 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
