Rheem 9 Kw Thru 36 Kw User manual

SURFACE MOUNTED ELECTRIC TANK-TYPE
WATER HEATERS 9 KW THRU 36 KW
RHEEM-RUUD line of commercial electric
water heaters come in a broader range of
models. Our completely redesigned single panel
control center with hinged door features ready
access to all controls and elements. With single
or three phase operation, these units provide the
most versatile and dependable operation we’ve
ever offered in a commercial electric water
heater.
Thick, R-Foam
®
insulation completely surrounds
the tank, maximizing heat retention while improv-
ing energy costs.
Features the Lifeguard
®
high-efficiency stainless-
steel clad elements for long element life and
performance.
Seven different inputs from 9 KW to 36 KW to
meet most commercial and industrial needs.
Model Applications
In addition to being suitable for general commer-
cial hot water applications, these units are also
ideal for point-of-use installations, eliminating
costly temperature loss in long piping runs. A
single unit can be used as a booster heater to
satisfy the hot water requirements of commercial
dishwashers. A single temperature storage unit,
when installed with a mixing valve, will supply
two temperatures in food service establishments.
For larger volume hot water requirements, 2, 3 or
4 units can be parallel manifolded, using optional
factory kits.
Energy Information
Rheemglas
®
commercial electric water heaters are quality engineered to provide the maximum amount of hot
water available from storage capacity of the tank and energy input of heating elements. Surface mounted
thermostat models provide water from 120°F to 160°F (50°C to 71°C). Detailed Engineering Information for
208, 240 and 600 volt models with single or three phase operation will be found in Table A, B or C.
These units have been tested according to procedures specified by CSA and meet or exceed the energy
efficiency requirements of ASHRAE Standard 90.1b 1992 requirements for energy conservation.

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 factory
installed anode rods or cathodic protection.
WATER CONNECTIONS – Hot outlet and
cold inlet are 1-1/2" NPS brass nipples which pre-
vent excessive turbulence of heated water and
result in optimum tank draw.
R-FOAM®INSULATION – A rigid
polyurethane foam insulation provides superior
insulating qualities and improves efficiency.
Exceeds R-16 insulation factor. Our patented
process of injecting R-Foam directly into the insu-
lating cavity adds additional durability and tough-
ness to the heater jacket. Fiberglass insulation
guards against heat loss in the heating element
compartment, and provides easy service access.
SINGLE PANEL CONTROL BOX – With
hinged door, provides immediate access to all
electrical components and elements.
HEATING ELEMENTS – Separate screw-in
type LIFEGUARD
®
elements on 50, 85 and 120
gallon models feature a stainless steel outer
sheath of INCO-LOY
®
800, surrounding a
Nichrome wire filament, to resist water chemical
corrosion and burn-out even in air or sediment…
for long element life and long life performance.
Elements are directly immersed in the water for
efficient transfer of heat, and are easily changed
by simply screwing new ones into the tank.
TERMINAL BLOCK – All models are
equipped with CSA listed terminal blocks for
simplicity of installation. This new terminal block
will accept either copper or aluminum field
connect wire.
ELECTRICAL CONNECTIONS – Pre-wired,
accessible control box with multiple knock-outs on
top and side in size selections to match the
Canadian Electrical Code. Sizes range from 1/2"
to 2". A grounding screw is provided for attaching
an equipment grounding conductor.
AUTOMATIC TEMPERATURE
CONTROL – Temperature is maintained by a
surface mounted thermostat adjustable to provide
water 120°F to 160°F (50°C to 71°C) that insure
instant shut off at the selected temperature for
safety and economy of operation. Over tempera-
ture protection is provided by surface mounted
high temperature limit controls, one per heating
element, factory set at 190°F (88°C).
STANDARD EQUIPMENT ASME T&P
RELIEF VALVE – This is a double safety valve
that relieves when temperature or pressure
becomes excessive.

SYSTEM SENTINEL – All models
employ a diagnostic panel utilizing light
emitting diodes (L.E.D.), corresponding
to the number and location of each
heating element. L.E.D.’s are energized
when the electric elements are operat-
ing. An unlit L.E.D. pinpoints the exact
location of a non-functioning element,
making element operation diagnosis
simple and positive.
The minimum distance to provide
adequate clearance for protection of
combustible material is 0 inches from
jacket and 18 inches from access
door. However, additional clearance for
accessibility to permit inspection and
servicing such as removing heating
elements or checking controls must be
provided. All models are approved for
installation on combustible flooring.
