to personnel, use only Authorized Hatco Service  
Agents and Genuine Hatco Parts when service  
is required.  
Genuine Hatco Replacement Parts are specified  
to operate safely in the environments in which  
they are used. Some aftermarket or generic  
replacement parts do not have the characteristics  
that will allow them to operate safely  
in Hatco equipment. It is essential to use  
Hatco Replacement Parts when repairing Hatco  
equipment. Failure to use Hatco Replacement  
Parts may subject operators of the equipment  
to hazardous electrical voltage, resulting  
in electrical shock or burn.

* Based upon NEC 2002 Code  
† Based upon THHN wire rated 90ºC.  
NOTE: NSF Standard 4 has recently 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 NSF Standard 4.  
The Hatco FR2 Series heating unit 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  
which 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 NSF performance  
requirements. The Hatco FR2 unit is listed with NSF 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 NSF Standard 4. Simply hanging an NSF listed FR2 unit on the appliance does not transfer NSF listing  
to the entire appliance.

The amount of lime and mineral content in the water  
and how often the unit is operated will dictate how  
often the unit needs to be delimed.  
7. Thoroughly flush heater through the front and rear  
openings with fresh water for several minutes until  
discharge is clear.  
Units used with water that contains high lime  
and mineral content may require deliming  
on a daily basis.
