To reduce the number of calculated feet always use smooth 6in. radius bends.
Note - Separation tubes
are installed in a Flat -
Horizontal or Vertical
position only!
For more information
refer to the installation
manual.

An onsite bend of less than 6 in. radius is
calculated at .35 Equivalent Feet.
Halcyon HFI system requires any bends tighter than a
6 in. radius to be counted as extra feet of pipe.
• Count the number of bends that have a less than 6 in.
radius ______(#)
• Multiply the number of bends by 0.35 = (Equivalent
Length)
• Add the Equivalent length to the actual feet of installed
line set = the calculated length.
3.5 feet added to actual length makes the
equivalent pipe length you must calculate
.
Example: (Your pipe sizes are 5/8 and 3/8)
A System with 5 bends each less than 6 in radius
between the outdoor unit and the 1st branch box.
5/8 - Multiply no. of bends 5 X 0.35 = 1.75(ft)
3/8 - Multiply no. of bends 5 X 0.35 = 1.75(ft)
Now add those 2 together to equal=
3.5 (ft)
When brazing:
Refer to the installation manual when using elbows or
hard pipe for pipe length calculation.
