The Advance Tabco SU-90-120 Autofill Assembly For 120 Volt Electric Hot Food Tables is a specialized component tailored for the SW, HDSW, DISW, and DISLSW series. This factory-installed autofill assembly is integral for maintaining optimal water levels in these electric hot food tables, enhancing efficiency and operational convenience. It operates at 120v/60/1-ph with a minimal power requirement of 10 watts for the sensor and 110v/60/1-ph for the control board. An essential feature is the requirement of a -M manifold drain upgrade, which is available at an additional cost, though not necessary for models DISW-1-120, DISW-1-240, or within the HDSW series. This assembly is not available for individual purchase, ensuring it is seamlessly integrated into the hot food table at the point of manufacture. The SU-90-120 is a pivotal component for commercial kitchens and food service environments that demand consistency and reliability in food warming equipment. By automating the water replenishment process, it minimizes manual intervention, thereby reducing labor and ensuring precise water levels are maintained, contributing to maintaining the quality and safety of food service operations.
