IMPORTANT SAFETY INFORMATION
MODEL DESCRIPTION
4
Form No. HHM-0517
All Models
3CS2 and FR2 series Hydro-Heaters mount under a sink or
holding vessel, leaving the interior of the holding vessel free of
obstructions. Hydro-Heaters feature a tubular water chamber
with a spiral heating element wrapped around the outside. They
include a stainless steel front, powdercoated body, a low-water
cut-off system, and a convenient drain.
Each unit comes with a one year parts and labor warranty. Units
are shipped completely assembled and ready to install with all
gaskets and fittings.
Optional features include a stainless steel body and base, an
Auto-Fill system, a remote mounted control, and a security
package. A flush hose kit is available as an accessory. Refer to
the OPTIONS AND ACCESSORIES section for details.
3CS2 Models
The Hatco 3CS Hydro-Heater is designed for use with any
manual dishwashing operation. It maintains a continuous supply
of sanitizing rinse water at 180ºF (82ºC). The heater utilizes
advanced electronic controls and “free flow” technology to
ensure responsive and efficient operation.
FR2 Models
The Hatco FR2 Hydro-Heater is designed to be used with a
Bain-Marie or Food Rethermalizer to heat or hold foods at safe
temperatures between 140ºF and 190ºF (60° and 88ºC). An
electronic controller with digital display maintains an accurate
setpoint temperature, and “free flow” technology ensures
responsive and efficient operation.
FR2-3 and FR2-4 models are available with an optional
48″ (1219 mm) cord and plug.

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.
For units with Auto-Fill, do not exceed an incoming water
temperature of 140°F (60°C) or incoming water pressure of
80 psi (550 kPa).
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.
Standard and approved manufacturing oils may smoke up
to 30 minutes during initial startup. This is a temporary
condition. Operate unit correctly until smoke dissipates.
NOTICE
Do not use excessive force when tightening unions or nuts.
Over-tightening 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.
