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):

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.
