INTRODUCTION

Hatco FR and 3CS heaters are designed to supply temperature­controlled water to a sink or holding vessel located above the
heater. Water flows by natural convection from the sink or
holding vessel into the heater directly downward into the rear
reservoir. The rear reservoir acts as a soil collection sump.

Debris that could affect the heating element operation settles
out in the sump to be drained away later. The debris free water
flows into the second reservoir in which the heating elements
are mounted. The water is heated and returns upward to the
sink or holding vessel.

All electrical and plumbing connections are factory-assembled
and ready for installation.

Hatco FR and 3CS Water 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 thoroughly inspected and tested
prior to shipment.

This manual provides the installation, safety, and operating
instructions for Hatco Water Heaters. Hatco recommends that
all installation, operating, and safety instructions appearing in
this manual be read prior to installation or operation of a unit.

Safety information that appears in this manual is identified by
the following signal word panels:

WARNING indicates a hazardous situation which, if not
avoided, could result in death or serious injury.

CAUTION indicates a hazardous situation which, if not
avoided, could result in minor or moderate injury.

NOTICE is used to address practices not related to
personal injury.

WARNING

CAUTION

IMPORTANT SAFETY INFORMATION

Read the following important safety information before using this equipment to avoid serious
injury or death and to avoid damage to equipment or property.

ELECTRIC SHOCK HAZARD:

• Units supplied without an electrical cord and plug
require a hardwired connection to on-site electrical
system. Connection must be properly grounded and
of correct voltage, size, and configuration for electrical
specifications of unit. Contact a qualified electrician to
determine and install proper electrical connection.

• Units supplied with an electrical cord, plug, and
receptacle require installation of receptacle to on­site electrical system. Connection must be properly
grounded and of correct voltage, size, and configuration
for electrical specifications of unit. Contact a qualified
electrician to determine and install proper electrical
connection.

• Unit must be installed by qualified, trained installers.
Installation must conform to all local electrical and
plumbing codes. Installation by unqualified personnel
will void the unit warranty and may lead to electric
shock or burn, as well as damage to unit and/or its
surroundings. Check with local plumbing and electrical
inspectors for proper procedures and codes.

• Unit is not weatherproof. Locate the unit indoors where
the ambient air temperature is a minimum of 70°F
(21°C).

• Turn OFF power switch, unplug power cord/turn off
power at circuit breaker, and allow unit to cool before
performing any cleaning, adjustments, or maintenance.

• DO NOT submerge or saturate with water. Unit is not
waterproof. Do not operate if unit has been submerged
or saturated with water.

• Do not clean unit when it is energized or hot.

• This unit is not “jet-proof” construction. Do not use
jet-clean spray to clean this unit.

• Discontinue use if power cord is frayed or worn.

• Do not attempt to repair or replace a damaged power
cord. Cord must be replaced by Hatco, an Authorized
Hatco Service Agent, or a person with similar
qualifications.

• This unit must be serviced by qualified personnel only.
Service by unqualified personnel may lead to electric
shock or burn.

• Use only Genuine Hatco Replacement Parts when
service is required. Failure to use Genuine Hatco
Replacement Parts will void all warranties and may
subject operators of the equipment to hazardous
electrical voltage, resulting in electrical shock or burn.
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.

FIRE HAZARD:

 • Installunitwithaminimumof3-1/2″(89mm)ofspace

from bottom of unit to all combustible surfaces to
prevent combustion.

• Do not use harsh chemicals such as bleach (or cleaners
containing bleach), oven cleaners, or flammable
cleaning solutions to clean this unit.

Make sure all operators have been instructed on the safe
and proper use of the unit.

This unit is not intended for use by children or persons
with reduced physical, sensory, or mental capabilities.
Ensure proper supervision of children and keep them away
from the unit.

Hatco Corporation is not responsible for actual food
product serving temperature. It is the responsibility of the
user to ensure that food product is held and served at a
safe temperature.

This unit has no “user-serviceable” parts. If service
is required on this unit, contact an Authorized Hatco
Service Agent or contact the Hatco Service Department at
800-558-0607 or 414-671-6350.

BURN HAZARD:

• Some exterior surfaces on unit will get hot. Avoid
unnecessary contact with unit.

• Drain water may reach temperatures in excess of 200°F
(93°C). Use appropriate plumbing materials when
installing drain.

• Water in holding vessel may reach temperatures in
excess of 190ºF (88ºC). Use appropriate protection
when operating unit.

• Hot water in unit may cause scalding injury. Allow unit
to cool before draining or cleaning.

• Do NOT set temperature control higher than 190ºF
(88ºC). Units are designed to heat water up to 190ºF
(88ºC). Water over 190°F (88°C) is very active and could
splash onto operator causing serious burns or injury.

Do not use extension pipes on the inlet and outlet
connections on water heater units. Poor performance or
unsafe conditions may occur.

Do not add cold food for rethermalizing while holding
hot food. The hot food will not maintain proper serving

NOTICE

Units are voltage-specific. Refer to specification label
for electrical requirements before beginning installation.
Connecting unit to incorrect power supply will void
product warranty and may damage unit.

This unit is intended for commercial use only — NOT for
household use.

Do not turn on power to unit until holding vessel has been
filled with water. Dry operation may cause element burnout.

Always drain holding vessel with power to unit off or
element burnout could occur.

Do not use excessive force when tightening unions or
nuts. Over-tighening and excessive force may cause leaks.

Incoming water in excess of 3 grains of hardness per
gallon (GPG) (0.75 grains of hardness per liter [GPL])
must be treated and softened before being supplied to
water heater(s). Water containing over 3 GPG (0.75 GPL)
will decrease efficiency, increase energy use, and reduce
operating life of unit through increased lime build-up.
Product failure caused by liming or sediment buildup is
not covered under warranty.

Use only delimers that are non-corrosive to aluminum,
brass, and stainless steel. Damage to unit caused by
corrosive materials is not covered under warranty.

Inspect unit regularly for lime and sediment buildup.
Excessive buildup may affect performance and reduce
operating life of unit. Unit failure due to lime or mineral
deposits is not covered under warranty.

NSF Criteria

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 FR 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 FR 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 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 listed with
NSF for construction only. Due to the fact that the FR is only a
portion of a larger system, it is impossible to do performance
testing until the FR unit is incorporated onto the water vessel.

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 FR unit
on the appliance does not transfer NSF listing to the entire
appliance.

WARNING

INSTALLATION

General

Hatco Water Heaters are shipped factory assembled. Care
should be taken when unpacking shipping carton to avoid
damage to unit and components enclosed.

ELECTRIC SHOCK HAZARD:

• Units supplied without an electrical cord and plug
require a hardwired connection to on-site electrical
system. Connection must be properly grounded and
of correct voltage, size, and configuration for electrical
specifications of unit. Contact a qualified electrician to
determine and install proper electrical connection.

• Units supplied with an electrical cord, plug, and
receptacle require installation of receptacle to on­site electrical system. Connection must be properly
grounded and of correct voltage, size, and configuration
for electrical specifications of unit. Contact a qualified
electrician to determine and install proper electrical
connection.

• Unit must be installed by qualified, trained installers.
Installation must conform to all local electrical and
plumbing codes. Installation by unqualified personnel
will void the unit warranty and may lead to electric
shock or burn, as well as damage to unit and/or its
surroundings. Check with local plumbing and electrical
inspectors for proper procedures and codes.

• Unit is not weatherproof. Locate the unit indoors where
the ambient air temperature is a minimum of 70°F (21°C).

FIRE HAZARD: Install unit with a minimum of 3-1/2″
(89 mm) of space from bottom of unit to all combustible
surfaces to prevent c ombustion.

1. Remove the unit from the box.

NOTE: To prevent delay in obtaining warranty coverage,

complete online warranty registration. See the
IMPORTANT OWNER INFORMATION section for
details.

2. Remove tape and protective packaging from all surfaces

of unit.

Sizing Information

Hatco recommends the following guidelines be used to ensure
proper operation and sanitation.

Installing 3CS and FR Models

A paper template is shipped with the unit and is used to locate
the sink strainer holes. Use the following procedure to mount
to the sink or holding vessel.

BURN HAZARD: Drain water may reach temperatures
in excess of 200°F (93°C). Use appropriate plumbing
materials when installing drain.

Do not use extension pipes on the inlet and outlet
connections on water heater units. Poor performance or
unsafe conditions may occur.

NOTE: FR Models should be installed with a perforated water

baffle (not supplied with unit) to distribute the heated

water properly. The baffle should be 3/4″ (19 mm) high

with a divider wall between the inlet and outlet. The

baffle should also have 3/4″ (19 mm) holes around the
periphery every 6″ (152 mm).

For 3CS Models in a Sink Heater Application

• Minimum of 2000 watts per square foot (2.2 watts per sq.

cm) of vessel top.

For FR Models in a Bain-Marie or Steam Table
Application

• Minimum 750 watts per square foot (0.8 watts per sq. cm)

of vessel top.

For FR Models in a Food Rethermalizer Application

• Minimum 2000 watts per square foot (2.2 watts per sq. cm)

of vessel top.

NOTE: Use one heater for a Bain-Marie up to 6′ (1829 mm)

long. Units over 6′ (1829 mm) require a minimum of two
heaters.
