Keurig K-3500 Use & Care Manual page 2

Before You Brew
CAUTION: This brewer is designed to handle local water pressures from 40 psig up to 125
psig. Consult a licensed plumber for water pressures in your area. Use plumbing fittings and
tubing specified to withstand 125 psig.
WARNING: Keurig® requires the use of an external water filter such as the Omnipure KQ8A
Water Filter, available from Keurig®. Failure to use a filter invalidates the brewer warranty.

Remove all pieces of packing tape from the brewer
and drip tray. Remove the clear plastic film from the
touchscreen.
NOTE: An external filter (KQ8A, #5572) can be mounted on the rear surface of
the brewer using the mounting screws provided.
Attach a threaded straight adapter to each of
the ports on the Omnipure KQ8A water filter and
tighten using an 11/16" (18mm) wrench. Make sure
the connections are secure, but do not over tighten.
Attach the filter mounting bracket to the Omnipure
KQ8A water filter using the four screws provided.
NOTE: The top of the Omnipure KQ8A water filter has two ports labeled in
port and out port. Make sure these ports are aligned with the filter mounting
bracket.
Loosen the two mounting screws located on the
upper-rear of the brewer and hang the filter kit
assembly. Tighten the screws but be careful not to
over tighten.
NOTE: The filter kit assembly comes with ¼" FPT ports for both inlet and outlet
and the plumbed water inlet to the brewer is ¾" female garden hose thread
(Invensys solenoid valve). ¼" OD LLDPE (Linear Low Density Polyethylene)
tubing is recommended (NSF compliant) between the filter kit assembly and
the brewer. NSF compliant fittings such as High Density Polypropylene type are
recommended.
Connect a stem elbow fitting to the import of the
filter kit assembly by pushing the stem elbow fitting
into the previously attached adapter. Push firmly
until the connection is secure. Secure LLDPE tubing
to the stem elbow fitting in the same fashion and
connect it to the local water supply.
