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 maximum
length of interconnecting piping, shown for each column, plus 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:
