*Model 320 can accept temporary excursions above 185°F (85°C) and maintain control without sustaining
internal damage. (ASSE 1017 certification requires exposure to 200°F (93°C) for a period of 30 minutes).
Prolonged operation of the Mixing Valve at such elevated temperatures is not recommended.
** Normal operating conditions are considered as a differential of approximately 122°F (50°C) between
the hot and cold inlet temperatures, and with differentials of 59°F (15°C) - 95°C (35°C) between the
blend setting and either supply. 59°F (15°C) is the optimum published minimum differential required to
achieve full thermal performance.
