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

CAUTIONS
Water in the unit and holding vessel is very
hot. Wear protective gloves and proper attire
when operating to avoid injury.
Do not use extension pipes on the inlet
and outlet connections on heater units.
Poor performance or unsafe conditions
may occur.
CAUTIONS
Do not overtighten unions or nuts.
Overtightening may cause leaks.
Do not turn the electrical current to the unit
on until the holding vessel has been filled
with water or element burnout may occur.
Inspect weekly for lime buildup inside unit.
Excessive amounts can affect unit
performance and reduce the operating life
of the unit.
To avoid any damage to the heater unit
use only delimers that are non-corrosive
to aluminum, brass and stainless steel.
Damage caused by corrosive material
or solutions is not covered under warranty.
Drain holding vessel with power to the unit
off, or element burnout may occur.
Water Quality Requirements - Incoming
water in excess of 3.0 grains of hardness
per gallon (GPG) (.75 grains of hardness
per liter) must be treated or softened before
being supplied to a Hydro-Heater. Water
containing over 3.0 GPG (.75 GPL)
will decrease the efficiency and reduce
the operating life of the unit.
IMPORTANT SAFETY INSTRUCTIONS
1
WARNINGS
Hatco FR2 series units are designed
for commercial use only by properly
trained personnel!
To avoid any injury, turn the power switch
off at the fuse disconnect switch/circuit
breaker or unplug the unit from the power
source and allow to cool completely before
performing any maintenance or cleaning.
For proper electrical installation conforming
to local electrical codes, consult a licensed
electrical contractor.
Units are designed to heat water up to 190ºF
(88ºC). To avoid any injury or damage DO
NOT set temperature controls to a setting
higher than 190ºF (88ºC).
For proper plumbing installation conforming
to local plumbing codes consult a licensed
plumbing contractor.
If service is required on this unit, contact
your Authorized Hatco Service Agent,
or contact the Hatco Service Department
at 800-558-0607 or 414-671-6350; fax
800-690-2966 or international
fax 414-671-3976.
This product has no “user” serviceable
parts. To avoid damage to the unit or injury
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.

or death, and to avoid damage to the equipment or property.
MODEL DESCRIPTIONS
2
ALL MODELS
The Hydro-Heater mounts easily to the underside
of a holding vessel, leaving the entire vessel
area free. Units are shipped ready to install
with all gaskets and fittings. Hydro-Heaters include
a stainless steel front, powder coated body, a lowwater cut-off system and a convenient drain outlet.
FR2 MODELS
The Hatco FR2 model heaters are designed
to be used with a Bain-Marie or Food
Rethermalizer to heat or hold foods
at temperatures between 140ºF (60ºC) and 190ºF
(88ºC). The desired holding temperature
is maintained by a special electronic controller
and “free flow”technology.
UNITS WITH BUILT-IN TEMPERATURE
CONTROL
Units with built-in electronic temperature controller
and display are excellent for installations where
the unit is easily accessible and viewing
is not obstructed.
UNITS WITH REMOTE TEMPERATURE
CONTROL
Units supplied with remote electronic temperature
controller and display allow for easy operator
monitoring and temperature control.

ELECTRICAL RATING CHART – FR2 MODELS
* 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.
