6KW - 54KW Electric Booster  
Commercial Water Heaters  
10 Gallon Capacity  
6KW thru 54KW  
Rheem-Ruud Electric Booster Water Heaters are specifically designed to fit under  
counters and deliver 180°F sanitizing rinse water for all stationary rack and convey-  
or type commercial dishwashers. They will raise preheated or cold water to 180°F  
rinse temperature for compliance with UL Sanitation (NSF5) and all Federal, State,  
County and 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.

Construction Features:  
System Sentinel –  
Long life heating elements –  
separate screw-in type elements  
feature a Nichrome wire filament,  
embedded in magnesium oxide  
sealed in a copper tube to resist  
water chemical corrosion…for long  
element life and a long life perform-  
ance. Elements are directly immersed  
in the water for maximum recovery  
efficiency (98%) and are easily  
changed by simply screwing new  
ones into the tank.  
Immersion  
Thermostat(s)  
all electric booster models employ an  
element diagnostic panel, utilizing  
light emitting diodes (L.E.D.), corre-  
sponding to the number and location  
of each heating element. L.E.D.’s are  
energized when the electric elements  
are operating. An unlit L.E.D.  
pinpoints the exact location of a  
non-functioning element, making  
element operation diagnosis simple  
and positive.  
®
Long life tank design –  
proprietary steel formulation with a  
unique coat of high temperature  
porcelain enamel to maximize  
corrosion resistance resulting in a  
superior tank design.  
Certifications and Ratings:  
• Efficiency – these models meet or exceed thermal efficiency and standby loss  
requirements of current ASHRAE standards. (Part of the Federally mandated  
Energy Policy Act (EPact)). Also exceeds energy efficiency codes of all states  
including California Energy Commission (CEC).  
• Safety and construction – these products are design certified by Underwriters  
Laboratories (UL) to meet UL standard 1453 as electric booster and commercial  
storage tank water heaters. All models are UL Sanitation (NSF5) and North  
Carolina Code compliant.  
CERTIFIED FOR A 150 PSI MAXIMUM WORKING PRESSURE.

Other Features:  
Integral fusing all models have integral  
120 volt control circuit all units are furnished  
with a fused 120 volt control circuit. All controls  
(thermostats, high temperature limit, etc.) are  
operated off of this basic 120 volt control circuit.  
This circuit is created by an internal multi-tap  
transformer of unique design that has four  
(4) taps for the primary voltages, 208, 240,  
277 and 480.  
fusing for each element.  
Anode rods two (2) magnesium anodes  
are installed in each tank for maximum  
corrosion resistance.  
Temperature and pressure relief valve –  
AGA/ASME rated and factory installed.  
Electrical connections pre-wired, accessible  
control box with multiple knock-outs on side in  
size selections to match the National Electric  
Code. Sizes range from 1/2" to 2". A grounding  
screw is provided for attaching an equipment  
grounding conductor.  
Water connections hot outlet and cold inlet  
are 1-1/4" NPT dielectric nipples which prevent  
excessive turbulence of heated water and  
results in optimum tank draw.  
Heavy insulation an effective blanket of  
insulation completely surrounds tanks to limit  
heat loss and assure high operating efficiency.  
Single panel control box with hinged  
stainless steel door, provides immediate access  
to all electrical components and elements.  
Stainless steel legs 6" stainless steel legs  
are provided with each unit.  
Terminal block all models are equipped
