Placement or Locating the Dispenser/Faucet
Professional Installation is Strongly Recommended
Preferred - Select a standard sink location to mount the faucet.
It is recommended that the faucet be placed in a hole provided on most sinks similar to the ones used for a sprayer, soap dispenser and/or dishwasher
air gap. If the hole or space is unavailable, an alternative location will be required:
MINIMUM HOLE REQUIRED 1/2”, MAXIMUM 1 3/8”
Option A: On the sink. This option is to drill a new hole into the sink rim itself, if space allows.
Option B: On the countertop next to a sink. This option is to position the faucet spout in the correct location to drain into the sink. This
requires a clearance around the faucet both above and below the countertop. Use the supplied dispenser as a template or see the
enclosed dispenser schematic and dispenser dimensions.
Prepare to drill the hole using the dispenser as a template.
• Sinks can be made of, but not limited to, stainless steel, copper, porcelain/steel, enamel/cast iron, man-made surfaces, stone, concrete, and/or materials
known or unknown at this time.
• Countertops can be made of, but not limited to, or be a combination of, natural stone, enamel, porcelain, concrete, wood, metals and/or man-made
materials known or unknown at this time.
CAUTION:
Please consult with the sink or countertop manufacture, supplier, fabricator, or installer for proper drilling techniques and methods.
EXTREME CARE MUST BE TAKEN IN DRILLING THE HOLE FOR ANY SURFACE. THE SURFACE MATERIALS OF SINKS AND COUNTERTOPS CAN CHIP OR CRACK.
THE MANUFACTURER ASSUMES NO RESPONSIBILITY FOR ANY DAMAGE RESULTING FROM THIS INSTALLATION.

WARNING:
USE SAFETY GLASSES OR OTHER EYE PROTECTION WHEN GRINDING OR DRILLING TO PREVENT POSSIBLE EYE INJURY DUE TO FLYING PARTICLES.
Note Dispenser Operation: Spout pulls out from faucet body and has 2 o-rings at base. Insert completely into bottom
of faucet body to prevent leaking. Spount swivels to direct water. Handle and tip can be
removed. Handle can be locked in open position for continuous ow.
Dispenser/Faucet Q & A
Q: I do not want to drill any extra holes or use a separate dispenser/faucet - what can I do?
A: An alternative to installing and using the dispenser/faucet is to consider a direct connection to your existing kitchen (cold side) faucet. Con-
nect the supply from the cold water angle stop to feed/inlet side of the ltration system as directed in this manual. Then connect the ltered/outlet
side to the cold feed side of the kitchen faucet. Special itings, that are readily available to the plumbing professional, will be required to t this application based on line size and materials used.
WARNING:
This is not a preferred method due to a more complicated install, lower ow rates to your kitchen faucet and most importantly, the possibility of water
quality issues as a result of the aerator at the end of the kitchen faucet not intended for ltered water.
Note:
There will be a diminishment in your ow rate to the cold side of the faucet (kitchen faucet has a ow rate of up to 2.3 gallons per minute and the
ltered water is delivered up to 1 gallon per minute). To get ltered water you must be sure you have the faucet to the cold side only. This application or
option may not be applicable for reverse osmosis systems.
Q: I would like to use another dispenser/faucet?
A: Based on many styles and nishes, a consumer may have another dispenser they would like to use. No problem, all these items have univer-
sal or industry standard ttings, or if not, can be easily adapted to t.
Standard Dispenser included: EWS, Inc. includes a standard chrome, long-reach, lead-free faucet with white handle and tip.
Options Available: EWS provides the following options to match other items at an additional charge:
Change your white tip and handle to black. Change your faucet to the following nshes; satin nickel, polished nickel, polished brass, or oil rubbed bronze
(all with black handle and tip). Inquire with your local EWS, Inc. distributor, contact an authorized internet distributor or visit us on the web.
Q: Can we connect the ltered water up to other devices?
A: Yes, simply connect by a “T” connection, the ltered water line to any instant hot, chiller, ice-maker, refrigerator, etc. Regarding ow rate, be
mindful of too many (3 or more) connections and/or any length limitations in excess of 15 feet to any item that may create issues with delivery rates.
