pipe
1. Standard length of connection pipe
• 16.4 ft (5 m),24.6 ft (7.5 m),26.2 ft (8 m)
2.Min. length of connection pipe is 9.8 ft (3 m).
3.Max. length of connection pipe and max. high difference.
4. The additional refrigerant oil and refrigerant charging required after prolonging
connection pipe
• After the length of connection pipe is prolonged for 32.8 ft (10m) at the basis of
standard length, you should add 1/3 in 3 (5 ml) of refrigerant oil for each additional
16.4ft (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 x
additional refrigerant charging amount per meter
• When the length of connection pipe is above 16.4 ft (5 m), add refrigerant according
tothe prolonged length of liquid pipe. The additional refrigerant charging amount
per meter is different according to the diameter of liquid pipe. See the
following sheet.
