ELECTRIC BOOSTER WATER HEATERS
6 KW THRU 18 KW
RHEEM-RUUD Electric Booster Water Heaters
are specifically designed to fit under counters and
deliver 180°F (82°C) sanitizing rinse water for all
stationary rack and conveyor type commercial
dishwashers. They will raise preheated or cold
water to 180°F (82°C) rinse temperature for
compliance with Local Health Department
Sanitation Codes. In addition, these models can
be used as circulating tank commercial electric
water heaters for gravity or pump circulation to
an auxiliary storage tank.
SYSTEM SENTINEL – An exclusive Element
Diagnostic Panel. Our new line of electric com-
mercial water heaters now includes a compact
instantaneous heater in an expanded range of
KW power inputs. The completely redesigned
single panel control center with hinged stainless
steel door provides ready access to all controls,
available for either single or three phase opera-
tion, these units provide the most versatile and
dependable operation we have ever offered in a
compact commercial water heater.
Engineering Information
Rheemglas®compact commercial electric water
heaters are quality engineered models designed
to provide the maximum amount of hot water from
the energy input of the heating elements. These
models include Rheem-Ruud’s System Sentinel™,
an exclusive Element Diagnositic Panel. A light
emitting diode monitors each element’s on-off
cycle and identifies any nonfunctioning element.
The precision thermostat(s) is easily adjustable
from 100°F to 180°F (38°C to 82°C), with positive
off position at low end temperature range. With
the design capability to be connected to 208, 240
and 600 volt, single or three phase power installa-
tions, they are ideally suited for a wide variety of
water heating systems. Detailed engineering
information is available in Tables A & B.

Construction Features
GLASS LINED STORAGE TANK – Heavy
duty steel tank protects with double coating of
exclusive Rheemglas
®
to resist the corrosive
action of hot water. Designed for 150 PSI working
pressure. Each tank is supplied with cleanout and
two factory installed magnesium anode rods for
maximum cathodic protection.
WATER CONNECTIONS – Hot outlet and
cold inlet are 1-1/4" NPS brass nipples which
prevent excessive turbulence of heated water
and result in optimum tank draw.
HEAVY INSULATION – An effective blanket
of insulation completely surrounds tanks to limit
heat loss and assure high operating efficiency.
STAINLESS STEEL DOOR AND
CONTROL PANEL – Ideal for food service
applications.
HEATING ELEMENTS – Separate elements
are of the screw-in type and are made of top
quality Nichrome
®
embedded in magnesium oxide
sealed in a tinned copper tube to afford corrosion
resistance and long life.
AUTOMATIC TEMPERATURE
CONTROL – Water temperature is maintained
by an external easily adjustable thermostat
starting with an OFF position and ranging from
100°F to 180°F (38°C to 82°C) that insure instant
power shut off at the selected temperature.
Over temperature protection is provided by an
immersion high temperature limit control, factory
set at 200°F (93°C).
MAGNETIC CONTRACTORS – All models
equipped with contractors, factory wired for
simplicity of installation and economical
maintenance throughout life of unit.
240 VOLT CONTROL CIRCUIT – all
units are furnished with a 240 volt control circuit.
All controls (thermostats, high temperature limit,
etc.) are operated off of this basic 240 volt control
circuit.
ELECTRICAL CONNECTIONS – Pre-wired,
accessible control box with knock-outs on the side
in size selections to match the Canadian Electrical
Code. Sizes range from 1/2" to 2". New terminal
block will accept both copper and aluminum wire.
STANDARD EQUIPMENT ASME T&P
RELIEF VALVE – This is a double safety valve
that relieves when temperature or pressure
becomes excessive.
STAINLESS STEEL 6" LEGS
SYSTEM SENTINEL™–An element
diagnostic panel, utilizing light emitting diodes
(LED) corresponding to the number and location
of each heating element are energized when the
electric elements are operating. An unlit LED
pinpoints the exact location of a non-functioning
element, making element operation diagnosis
simple and positive.
Optional Equipment
ELEMENT FUSING – In addition to all the
above construction features, there is internal
fusing available that protects all elements,
magnetic contractors, thermostats and internal
wiring circuits.
For optional fusing, suffix “F” should be added to
the model number. Ex. EG10CF-12KW
