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 Sheet 2.
● Additional refrigerant charging amount = prolonged length of liquid pipe X additional refrigerant charging amount per meter
