Hatco FR-3B User Manual

FR Food Rethermalizers /
Bain-Marie Heaters

Models: FR-3, -4, -6, -9,
FR-3B, -4B, -6B, -9B

The Hatco FR is designed to be used with a Bain­Marie or Food Rethermalizer to heat or hold foods
at safe-serving temperatures between 140°F (60°C)
to 190°F (88°C). The FR units mount under a sink
or holding vessel, with water being continually
circulated to avoid any "cool" spots.

Standard features

• Equipped with an Energy Cut-Off (ECO) for built-in
protection against higher-than-normal water temperature

• Desired holding temperature is maintained with an
adjustable water temperature control

• Includes a power On/Off toggle switch and standard 2"
(51 mm) plated brass plumbing ttings for mounting into a
holding tank

• Separate sump and heating compartment drains allow
for easy cleaning and sanitizing

• Shipped with a stainless steel front, powdercoated silver-

gray hammertone body and black base, and includes a
ve-year limited warranty

SIZING INFORMATION

For a Bain-Marie or Steam Table: MINIMUM 750 WATTS PER SQUARE FOOT
(0.8 WATTS PER SQUARE CM) of vessel top.

For a Food Rethermalizer: MINIMUM 2000 WATTS PER SQUARE FOOT (2.2
WATTS PER SQUARE CM) of vessel top.

Use one FR for a Bain-Marie up to 6' (1829 mm) long. Over 6', minimum two
required.

MUST BE INSTALLED WITH A PERFORATED WATER BAFFLE. This baffle is
not supplied with heater. The FR should be positioned with no more than 3’
(914 mm) on either side when mounted in holding vessel. Consult factory or
installation manual for fabricating details.

FOOD RETHERMALIZING REQUIREMENTS

NSF Standard 4 has 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 reaches 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 FR sesries heating unit is specifically made to be used 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 simply 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 FR 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 FR unit is UL Classified on NSF 4 for construction only.
Due to the fact that the FR2is 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.

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 and softened before being supplied to hot water
dispenser(s). Water containing over 3.0 GPG (.75 GPL) will decrease efciency and
reduce the operating life of the unit.

Note: Product failure caused by liming or sediment buildup is not covered

under warranty.
