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

WARNINGS

Hatco 3CS2 and FR2 series units are designed
for commercial use only by properly trained
personnel! To avoid any injury or damage
to the unit read and follow the instructions
contained in this manual. Do not operate this
equipment unless you have read and completely
understood the contents of this manual.

To avoid any electrical shock hazard, or physical
burns turn the power 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. Improper electrical
connections may cause a serious electrical
shock injury or may damage the unit.

For proper plumbing installation conforming
to local plumbing codes consult a licensed
plumbing contractor.

Units equipped with a power cord and plug
should be plugged into an electrical outlet
of the correct voltage, size and plug configuration.
If the plug and receptacle do not match, contact
a qualified electrician to determine the proper
voltage and size and install the proper
electrical outlet.

To prevent any injury or damage to the unit do
not pull unit by power cord.

To prevent any injury, discontinue use if power
cord is frayed or worn.

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

Form No. HHM-1103

IMPORTANT! Read the following important safety instructions to avoid personal injury or death,
and to avoid damage to the equipment or property.

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 daily for lime and sediment 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.

CAUTIONS

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 and softened before being supplied
to a Hydro-Heater. To maintain efficiency
and to extend the operating life “regular
deliming and cleaning” must be performed when
water supplied contains over 3.0 GPG (.75 GPL).

To avoid any damage to units with Auto-fill,
do not exceed the following:
Incoming Water Temperature: 140°F (60°C)
Incoming Water Pressure: 80 PSI (550 kPa)
