LEGEND
— Not Required
Pipe A — Suction Riser without Trap
Pipe B — Suction Riser with Trap
Pipe C — Suction Line Condensing Unit
NOTES:
1. Refer to the figure located to the right for suction line piping locations.
2. Pipe sizes are based on an equivalent length equal to the total length of
interconnecting piping, shown for each column, which accounts for 50%
for
fittings.
3. Suction and liquid line sizing is based on pressure drop equivalent to 2 F
(1.1 C) at nominal rating conditions.
4. All pipe sizes are OD inches. Equivalent sizes in millimeters follow:
in.
