Rheem-Ruud point-of-use electric commercial water heaters are designed to

provide hot water at the consumption point, eliminating costly temperature

loss in long piping runs.Well suited for a wide variety of applications, point-of-

use heaters are small enough for installation in limited spaces under coun-

ters, mop sinks, cabinets, or any remote area where modest quantities of hot

water are required.They are ideally suited for applications in retail stores,

public restrooms, office washrooms, kitchen and mop or bar sinks.

Construction Features:

•

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. A patented

R-Tech anode rod provides

advanced technology; equalizing

aggressive water action while

prolonging the effective life of

the anode rod and in turn the

life of the tank.

•

Long life heating elements –

Our patented resistor elements

are designed with a specially

treated, double layer of magne-

sium oxide and copper to

resist corrosion.

•

Efficient design –

Rigid polyurethane foam insulation

provides superior insulating

qualities resulting in reduced

operating costs.

•

Optional wall mounting kit –

The wall mounting kit provides an

easy way to mount the unit off the

floor, out of the way for more use-

able floor space in a small area.

Each kit is designed to be used on

walls with 16" stud centers. All

necessary parts are included in

this easy to install kit. (Note:The

2-1/2 gallon model comes stan-

dard with a wall mounting kit.)

•

Automatic temperature

control –

A surface mounted thermostat

automatically cycles on and off to

maintain the water temperature at

a desired preset level.

•

Temperature limiting control –

Automatically and safely cuts off

the power in the unlikely event that

the water temperature exceeds

190°F.

•

Temperature and pressure

relief valve –

AGA/ASME rated and factory

installed.

•

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 174 as electric storage

tank water heaters. All models are North Carolina Code compliant.

CERTIFIED FOR A 150 PSI MAXIMUM WORKING PRESSURE.
