HYDRO-HEATER SANITIZING SINK HEATERS

Models 3CS2-3, -4, -6 3CS2-3B, -4B, -6B, -9B

The Hatco Hydro-Heater is a state-of-the­art, high efficiency circulation water heater,
using a combination of “free-flow”
technology and advanced electronic
controls for circulating hot water by
natural convection in a sanitizing sink.

This heater features a tubular water
chamber with heating elements uniquely
wrapped outside the flow tube so
elements do not come in direct contact
with the water. The design reduces
sediment and lime buildup on the
element, resulting in longer life. A special
electronic controller maintains the
setpoint temperature assuring a
responsive and efficient operation.

FLEXIBILITY

Designed to fit under the center of
the sink, the 3CS2 is perfect for 3- or
4-compartment sinks, pot and pan sinks,
and bar sinks with 180°F to 190°F
(82°-88°C) controls.

QUALITY

The following features assure the finest
performance for years to come:

• Utilizes “free-flow” technology and
advanced electronic controls to assure
a responsive and efficient operation.

• All models include a stainless steel
front, powdercoated body, convenient
drain outlet, and clean-out caps.

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 water heater(s). Water containing over 3.0 GPG
(.75 GPL) will decrease the efficiency and reduce the operating life
of the unit.

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

covered under warranty.
