1. Standard length of connection pipe
● 5m, 7.5m, 8m.
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.

Basing on the length of standard pipe, add refrigerant accordin
g to the
requirement as shown in the table. The additional refrigerant charging amount
per meter is different according to the diameter of liqu
id pipe. See the
following sheet.
