†Nominal tons are based upon 95°F HW, 85°F CW, 78°F WB and 3 GPM/ton. The UPDATE web-based selection software provides JT model recommendations based on specific design requirements.

*For static pressure from 1⁄4" to 1⁄2" ESP, use next size larger motor.

**At normal operating water level in cold water basin.

Note: All piping connections are for standard GPM. Consult Recold for other flow rates.
