The Hatco FR is an electric food rethermalizer/bain marie heater with a stainless steel front, silver gray hammertone body, and black base. It has a power of 4.5 kW (balanced) and is NSF, UL, UL EPH Classified, ANSI/NSF 4, and CSA certified. This product is made in the USA. The FR is designed to be used with a bain marie or food rethermalizer to heat or hold foods at safe-serving temperatures between 140°F (60°C) to 190°F (88°C). It is mounted under a sink or holding vessel, with water being continually circulated to avoid any "cool" spots. The separate sump and heating compartment drains allow for easy cleaning and sanitizing. The desired holding temperature is maintained with an adjustable water temperature control. The FR is equipped with an Energy Cut-Off (ECO) for built-in protection against higher-than-normal water temperature. It includes a power On/Off toggle switch and standard 2" (51 mm) plated brass plumbing fittings for mounting into a holding tank. The product is shipped with a stainless steel front, powder coated silver gray hammertone body and black base, and comes with a five-year limited warranty. Options available at the time of purchase include 480 Volt, all stainless steel body and base, security package (Torx® Screws and Control Cover), CSA wiring (Canada only), and low-water cut-off (prevents element burnout from low-water conditions). Accessories for the FR include a flush kit (flush hose, stopper, and adapter), a 4' (1219 mm) cord with plug (NEMA 6-20P) and receptacle (NEMA 6-20R) for the FR-3 model, and a 4' (1219 mm) cord with plug (NEMA 6-30P) and receptacle (NEMA 6-30R) for the FR-4 model. The Hatco FR series heating unit is specifically made for food rethermalizing and meets the performance requirements of NSF Standard 4. However, it is designed to be incorporated into a hot water bath rethermalizer. Hatco does not supply the vessel or the system for holding the food in the vessel. The FR unit attaches to the bottom of the vessel and supplies hot water. The vessel manufacturer is responsible for testing and listing the entire rethermalizing appliance
