4. Piping Installation
4.1 Recommended Piping Diameters
Based on the proposed piping layout and the actual locations of both the In-Row Cooler and the condenser, calculate the total
equivalent piping distance, including bends and traps, to determine the necessary piping diameters.
Note:
For equivalent piping length longer than 100 ft. (30 m), use the long piping kit (SRCOOLLONGPKIT).
Look up the recommended piping diameters for both the discharge and liquid piping using the
Table: Recommended Piping
Diameters
.

Note:
For equivalent distance greater than 32.5 ft., the vertical discharge piping is generally one size smaller than the horizontal to improve
velocity.
