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.
