Configuration of connection pipe
1. Standard length of connection pipe
• 5 m, 7.5 m, 8 m
2. Min length of connection pipe
For the unit with standard connection pipe of 5 m, there is no limitation for the min length of
connection pipe. For the unit with standard connection pipe of 7.5 m and 8 m, the min length of
connection pipe is 3 m.
3. Max length of connection pipe

The calculation method of additional refrigerant oil and refrigerant charging amount 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):
(1) Additional refrigerant charging amount = prolonged length of liquid pipe × additional
refrigerant charging amount per meter.
(2) 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 Sheet 2.
