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.
* No additional oil charge is required. Charge with refrigerant per the nameplate label.
** For lengths greater than 32.5 ft. (10 m), additional oil must be added per the formula shown in section 6.2 Oil Charging and
additional refrigerant must be added per the formula.
