upon 80°F inlet water and 90°F ambient.
Compact, highly efficient water chiller units are designed for use
with any drinking fountain. Also connects to a bubbler, glass
filler or cold water dispenser. Converts a fountain into a water
cooler. Installs directly under fountain or other application, or
may be located in a service area to serve a remote outlet
(within 15 feet recommended). Also recommended for
photo-processing, medical or experimental laboratories and a

DEFINITION IN THE SAFE DRINKING WATER ACT OF 1986
AND LEAD CONTAMINATION CONTROL ACT OF 1988.
This Elkay Water Chiller is manufactured with a waterway system
utilizing stainless steel components and completely lead-free
materials. These waterways have no lead because all leadcontaining materials, such as leaded brass, have been
removed. All joints are brazed using silver solder only. No lead
solder is permitted. Ideal for use with filter treated
domestic water supply or reverse osmosis systems.
This water cooler is certified to NSF/ANSI 61and 372.
