Appendix 2: Configuration of Connection Pipe

Standard length of connection pipe(More details please refer to the specifications.)
Min length of connection pipeFor the unit with standard connection pipe of 5m, there is no limitation for themin length of connection pipe. For the unit with standard connection pipe of 7.5m and 8m, the min length of connection pipe is 3m.
Max. length of connection pipe and max. high difference.(More details please refer to the specifications.)
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

Appendix 3: Pipe Expanding Method

_ Note: _Improper pipe expanding is the main cause of refrigerant leakage.Please expand the pipe according to the following steps:

A: Cut the pip
- Confirm the pipe length according to the distance of indoor unit and outdoor unit.
- Cut the required pipe with pipe cutter.
B: Remove the burrs
- Remove the burrs with shaper and prevent the burrs from getting into the pipe.
C: Put on suitable insulating pipe.
D: Put on the union nut
- Remove the union nut on the indoor connection pipe and outdoor valve; install the union nut on the pipe.
E: Expand the port
- Expand the port with expander.

Note: “A” is different according to the diameter, please refer to the sheet below:

Outer diameter(mm)	A(mm)
Max	Min
Ф6 – 6.35 (1/4″)	1.3
Ф9 – Ф9.52 (3/8”)	1.6
Ф12 – 12.70 (1/2”)	1.8
Ф16 – 15.88 (5/8”)	2.4

F: Inspection
- Check the quality of expanding port. If there is any blemish, expand the port again according to the steps above.
