Stop! Does your faucet have a pullout sprayer?
Unfortunately, Aquasana drinking water filters do not fit
on these faucets. In order to have filtered water in your
home, please consider our Under Counter filter with a
faucet that matches your decor!

The AQ-4000 is available in three finishes with two diverter valve styles

“Pure Satisfaction”
All Aquasana products oer a 90-day 100% satisfaction guarantee. (A 1-year warranty is included, which
covers defects in materials and workmanship.) If for any reason you are not satisfied with your purchase,
simply call us, or the dealer you purchased from, for a Return Authorization Code and a full refund will be

Important:
For the first 72 hours, the faucet diverter valve will drip intermittently, until the filters become fully
saturated. Once they are saturated you should anticipate a residual flow of water each time you use the
filter, as the system is vented and designed to clear the line.
Precautions:
Aquasana is not liable for consequential or incidental damages due to improper installation.
• Filter is only to be used with cold water.
• Never use this system on constant-pressure applications such as ice makers or drinking fountains.
• If the faucet diverter valve does not t, you will need to install one of the brass faucet adapters before
attaching it. The brass faucet adapters can be tightened using the install tool. (if the supplied brass
faucet adapters do not fit you can obtain the right size from your local hardware store. Be sure to bring
your aerator and diverter valve to find the perfect match.)
• Make sure the rubber washer is in place inside the chrome swivel collar on the diverter valve.
• If you experience a leak at the hose connection, disconnect and re-seat the hose.
* Supplied brass faucet adapters and seals are not included in or covered by the system certification.
