INTRODUCTION
Hatco FR2 Hydro-Heater Food Rethermalizers/Hot
Food Table Heaters are designed to supply
temperature-controlled water to a holding vessel
(sink or tank) located above the heater. Water
flows by natural convection from the holding vessel
directly into a tubular water chamber with heating
elements uniquely wrapped on the outside
of the flow tube. The heating elements do
not come in direct contact with the water
eliminating sediment and lime buildup
on the element, resulting in longer life. The heated
water flows upward and returns to the holding
vessel. A special electronic controller maintains
the setpoint temperature assuring a responsive
and efficient operation.
The unit electrical and plumbing connections
are factory-assembled and ready for installation.
This manual provides the installation, safety
and operating instructions for the Hydro-Heater
Food Rethermalizers/Hot Food Table Heaters.
We recommend all installation, operating and safety
instructions appearing in this manual be read prior
to installation or operation of your Hatco Hydro-
Heater. Safety instructions that appear in this
manual after a warning symbol and the words
WARNING or CAUTION printed in bold face
are very important. WARNING means there
is the possibility of serious injury or death
to yourself or others. CAUTION means there
is the possibility of minor or moderate injury.
CAUTION without the symbol signifies
the possibility of equipment or property
damage only.
Hatco Hydro-Heaters are a product of extensive
research and field testing. The materials used
were selected for maximum durability, attractive
appearance and optimum performance. Every
unit is thoroughly inspected and tested prior
to shipment.
