NOTE:
1. If equivalent piping length falls between two columns above, choose
the longer equivalent length.
2. Dual circuit units should use the same line size on both circuits.
3. If hot gas line
refrigerant flow is upward, use “Vertical Up”.
4. If hot gas line refrigerant flow
is downward, use “Horizontal & Vertical
Down
”.
