4. The additional refrigerant oil and refrigerant charging required after prolonging connection pipe.
• After the length of connection pipe is prolonged for 10 m at the basis of standard length, you should add
5 ml of refrigerant oil for each additional 5 m of connection pipe.
• The calculation method of additional refrigerant charging amount (on the basis of liquid pipe):
Additional refrigerant charging amount = prolonged length of liquid pipe × additional refrigerant charging amount per meter
• 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:
