SANITIZING SINK HEATERS

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

The Hatco 3CS Sanitizing Sink Heater
makes manual warewashing faster and
more convenient. It maintains a continuous
supply of sanitizing rinse water without
taking up valuable sink space.

FLEXIBILITY

Designed to fit under the center of
the sink, the 3CS is perfect for 3- or
4-compartment sinks, pot and pan sinks,
and bar sinks.

The 3CS features a unique dual reservoir
system. One reservoir contains the
heating element and should always be
filled with water. The other reservoir
traps and collects soil carried from other
sink compartments. This reservoir is
easily emptied after each use by a
convenient drain.

QUALITY

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

• All models include stainless steel front,
powdercoated silver-gray hammertone
body, and convenient side drain.

• Every Hatco 3CS is equipped with an
ECO (Energy Cut-Off) wired into the
electrical circuit. This built-in protection
“breaks” the power to the elements if
the temperature of the water goes
above the normal thermostat setting.

• An on-off toggle switch activates the
heater and a yellow light indicates
when power is on. A red light is an
overtemp indicator pointing out the
need to refill the unit with water and
reset the unit.

• Each 3CS model features a stainless
steel tank with a five-year warranty.

• Available with an optional temperature
monitor or temperature light that
indicates when water reaches the
sanitizing temperature.

• The 3CS is shipped ready to install
with all gaskets and fittings.

• Meets NSF Standard of 180°F (82°C)
for dish sanitizing.

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.

3CS Sink Heaters are sized based on 140°F (60°C) supply
water with a 30-minute preheat period to reach the sanitizing
temperature. Sink Heaters are mounted in the center of the
third compartment sink with standard plumbing fittings
provided. Two 2" (51 mm) diameter holes are required for these
fittings and a full-size template is provided to locate holes in
the sink. The 3CS Sink Heater is easily attached to the
plumbing fittings with self-contained unions.
