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 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 reducing 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
