INTRODUCTION

Hatco 3CS2 Hydro-Heater Sanitizing Sink Heaters and FR2 Hydro-Heater Food Rethermalizers/Bain-Marie Heaters are designed to supply temperature-controlled water to a sink or holding vessel located above the heater. Water flows by natural convection from the holding vessel directly into a tubular water chamber with heating elements uniquely wrapped around the outside of the flow tube. The heating elements do not come in direct contact with the water, reducing sediment and lime buildup on the element and resulting in longer life. The heated water flows upward and returns to the holding vessel.

A special electronic controller maintains the setpoint temperature ensuring a responsive and efficient operation. The unit's electrical and plumbing connections are factory-assembled and ready for installation.

Hatco Hydro-Heaters are products of extensive research and field testing. The materials used were selected for maximum durability, attractive appearance and optimum performance. Every unit is inspected and tested thoroughly prior to shipment.

This manual provides the installation, safety, and operating instructions for the Hydro-Heater Sanitizing Sink Heaters and Food Rethermalizers/Bain-Marie Heaters. Hatco recommends that all installation, operating, and safety instructions appearing in this manual be read prior to installation or operation of a unit.

NSF Criteria

éSF Standard 4 added performance requirements for food rethermalizing. The requirements mirror the requirements for food rethermalizing in the FDA Food Code. The basic requirement is that food reach a temperature of 165°F (74°C) in a time period of two hours or less. Appliances that are manufactured for the purpose of rethermalizing food will need to meet these performance requirements in order to be listed to éSF Standard 4.

The Hatco FR2 Series Hydro-Heater is specifically made for food rethermalizing, however, the heating unit is designed to be incorporated into a hot water bath rethermalizer. Hatco does not supply the vessel that contains the water, nor the system that determines how food is placed and held in the vessel. The Hatco FR2 unit attaches to the bottom of the vessel and supplies hot water to the vessel.

Hatco does supply sizing recommendations to enable the appliance manufacturer to correctly size the FR2 unit to the vessel. However, there are variables in the way that the vessel is manufactured that affect its ability to pass the éSF performance requirements. The Hatco FR2 unit is listed with éSF for construction only. Due to the fact that the FR2 is only a portion of a larger system, it is impossible to do performance testing until the FR2 unit is incorporated onto the water vessel.

The result is that it is the responsibility of the vessel manufacturer to have the entire rethermalizing appliance tested and listed in accordance with éSF Standard 4. Simply hanging an éSF listed FR2 unit on the appliance does not transfer éSF listing to the entire appliance.

General

Hatco 3CS2 and FR2 Series Hydro-Heaters are shipped fully assembled. Care should be taken when unpacking the shipping carton to avoid damage to unit and components enclosed.
