Specification Sheet

GENERAL
Self-contained, wall hung electric refrigerated water cooler.
Chilling capacity of 50°F drinking water, based upon 80°F inlet
water and 90°F ambient.
Models EZO4 and EZO8 sensor-operated coolers have unique
Hands-Free
®
operation and patented* valve with built-in flow reg-
ulator to provide constant stream from 20 to 105 psi.
Non-pressurized stainless steel cooling tank is standard. Non-
pressurized water tank is located after bubbler valve, so that tank
is subject to line pressure only when sensor is activated.
ADA COMPLIANT
These Water Coolers comply with the requirements of A.D.A.
(Americans with Disabilities Act) when properly installed. Also
meets the guidelines for children’s environments providing the
floor to orifice height is 30" or less and proper clear floor space
is provided for parallel approach. (Based on Architectural and
Transportation Barriers Compliance Board final ruling.) Check
Local and State Codes.
NO LEAD DESIGN
These Water Coolers are certified to be lead-free as defined by
the Safe Drinking Water Act. Elkay Water Coolers are manu-
factured with a waterway system utilizing copper components
and completely lead-free materials. These waterways have no
lead because all lead materials, such as leaded brass, have been
removed. All joints are brazed using silver solder only. No lead
solder is permitted. A strainer with an easily cleanable screen is
provided to allow trapping and convenient removal of waterborne
particulate of 140 microns and larger prior to their entry into the
water cooler.
These water coolers are certified to
NSF/ANSI 61.
COOLING SYSTEM
Motor Compressor: Hermetically sealed, reciprocating type,
115V, 60 Hz single phase. Sealed-in lifetime oil supply. Equipped
with electric cord and three prong molded rubber plug (domestic
models).
Condenser: Fan cooled, copper tube with aluminum fins. Fan
motor is permanently lubricated.
Cooling Unit: Combination tube-tank type. Self cleansing. Tube
portion is continuous coil of copper tubing. Tank is stainless
steel. Fully insulated with EPS foam which meets Underwriters
Laboratories Inc. requirements for self-extinguishing material.
Refrigerant Control: Refrigerant HFC-134a is controlled by
accurately calibrated capillary tube for positively trouble-free
operation.
Temperature Control: Enclosed adjustable thermostat is fac-
tory pre-set. Requires no adjustment other than for altitude
requirements. Easily accessible.
CONSTRUCTION
Electronic Sensor Hands-Free
®
Operation: On-off solenoid valve
is actuated by an infrared light beam sensor. When light beam is
interrupted by subject in front of cooler desiring a drink, the sensor
actuates the solenoid valve which then opens to allow water flow.
No physical contact with cooler is required. A built in time delay is
provided to prevent actuation by persons moving past cooler. There
is a maximum running time of 30 seconds to prevent malicious
damage to the cooler or water damage if sensor vision is blocked.
Unit automatically resets when blockage is removed. Sensor range
is adjustable.
Frame: Galvanized structural steel chassis supports refrigeration
system and fastens to wall. Provides increased structural integrity
and rigidity to cooler.
Stainless Steel Basin: One piece polished to a uniform Elkay
bright luster finish. Basin has integral drain grid, embossed
bubbler pad. No exposed fasteners.
Exclusive Flexi-Guard
®
Safety Bubbler*: Innovative design
utilizes an infused anti-microbial pliable polyester elastomer to
prevent accidental mouth injuries. Flexes on impact, then returns
to original position. Strong. Abrasion-resistant. Anti-sweat.
Keyed in location to prevent rotation.
Upper Shroud: Contoured shock-absorbing, provides additional
protection against accidental injury. No exposed fasteners.
Lower Shroud: One piece easy to remove and replace. Allows
access to internal components from three sides.
Cabinet: Cabinet design allows for flush to wall mounting. No
recess space is required.
Color Selection: Unless otherwise specified cabinet is two-tone
gray on upper shroud with textured gray lower shroud. Stainless
Steel lower shroud available at extra cost.
5 YEAR LIMITED WARRANTY on the refrigeration system of the
unit. Electrical components and water system are warranted for
12 months from date of installation. Sample Certificate available
on request.
Elkay Pressure-Type Water Coolers are designed to operate on
20 psi to 105 psi supply line pressure. If inlet pressure is above
105 psi, a pressure regulator must be installed in the supply line.
Any damage caused by reason of connecting this product to sup-
ply line pressures lower than 20 psi or higher than 105 psi is not
covered by the warranty.
