Water Coolers – Barrier-Free Access (Adult & Child)

S PECI F I C AT I O N S

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 vide constant stream from 20 to 105 psi water pressure.

Non-pressurized stainless steel cooling tank is standard. Nonpressurized water tank is located after bubbler valve, so that tank is subject to line pressure only when sensor is activated.

NO LEAD DESIGN

These Water Coolers are certified to be lead-free as defined by the Safe Drinking Water Act. Elkay Water Coolers are manufactured 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.

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

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 loca tion 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.

Protected by Elkay’s 5 Year Limited Warranty on the refrigeration system of the unit.

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 supply line pressures lower than 20 psi or higher than 105 psi is not covered by the warranty.

Open space rough-in design permits new installation or replacement of existing fountains and coolers with this Elkay cooler when rough-in is within the outline shown. When the cooler is mounted as shown the location available is from 15" to 21-11/16" from floor and 1-1/16" to 7-1/4" from the left of centerline. Space is also available from 21-11/16" to 24-5/8" from floor and 2-3/4" to 7-1/4" from the left of centerline. Additional space is also available from 24-5/8" to 26-11/16" from floor and 3-3/4" to 7-1/4" from the left of centerline. Connections approaching the limits of these areas may be restricted and should only be considered for use until after an examination of the cooler has been made.

his water cooler has been designed and built to provide water to the user which has

ot been altered by materials in the cooler waterways.

he grounding of electrical equipment such as telephone, computers, etc., to water

ines is a common procedure. This grounding may be in the building but may also

ccur away from the building. This grounding can cause electrical feedback into a

ater cooler creating an electrolysis which creates a metallic taste or causes an

ncrease in the metal content of the water. This condition is avoidable by installing the

ooler using the proper materials as shown below.

This water cooler must be connected to the water supply using a dielectric coupling. The cooler is furnished with a non-metallic strainer which meets this requirement.

The drain trap which is provided by the installer should also be plastic to completely

solate the cooler from the building plumbing system.
