Installation and Maintenance
Service Manual
Appendix:
1.Standard length of connection pipe(More details please refer to the specifications.)
2.Min. length of connection pipe is 3m (10ft).
3.Max. length of connection pipe and max. high difference.(More details please refer to the specifications.)
4.The additional refrigerant oil and refrigerant charging required after prolonging connection pipe
● After the length of connection pipe is prolonged for 10m (33ft) at the basis of standard length, you should add 5ml (.17oz) of refrigerant
oil for each additional 5m (16ft) 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 acc
ording 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
