Non-Keurig®brand pods may cause
brewer malfunction or injury.

puncture the pod, one above the K-Cup® pod
holder and the other in the bottom of the
K-Cup® pod holder. To avoid risk of injury,
be aware of the needle locations.
5. CAUTION: There is extremely hot water

during the brew process. To avoid risk of
injury do not lift the handle or otherwise
open the handle during the brew process.

Plumbing Instructions
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.
1. Remove all pieces of packing tape from the
brewer and drip tray. Remove the clear plastic
film from the touch screen.
NOTE: An external filter (KQ8A, #5572) can be mounted on the rear
surface of the brewer using the mounting screws provided.
2. 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
overtighten.
3. 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.
4. 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
5. Connect a stem elbow fitting to the port 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.
6. You may wish to install a shut-off valve
between the water source and the Omnipure
KQ8A water filter. To do this, cut some LLDPE
tubing to size and connect it by pushing the
tubing into the shut-off valve until secure.
7. Connect a long length of tubing to the out
port of the filter kit assembly. Do not connect
the brewer yet.
8. The Omnipure KQ8A water filter needs an
initial flush to clear any carbon deposit. Bring the
long length of tubing to a container or sink.

9. Turn on water supply and allow
at least four gallons of water to
flush through the filter. Turn off
water supply.
10. Cut the tubing to the proper
length and connect a stem elbow
fitting to the cut end of tubing.
Thread the ¾” female garden hose
onto the brewer inlet valve located
at the lower rear of the brewer.
Push the stem elbow fitting into it
until secured firmly. Then, turn on
water supply.
NOTE: Water and waste piping and connections shall
comply with the International Plumbing Code 2003,
International Code Council (ICC) or the Uniform
Plumbing Code 2003, International Association of
Plumbing and Mechanical Officials (IAPMO).

Commercial Rating ensures that the K-3500TM
brewer will stand up to the demands of your
coffee station. Enjoy the convenience of a touch
screen, an industrial easy-grip handle, and a
plumbed water tank for back-to-back brewing.
Brewing Iced Beverages: Fill a 16 oz. cup (do not
use glass) to the top with ice and place a K-Cup®
pod into your brewer. Select your brew size-we
recommend selecting 6 oz. or 8 oz. Press Brew!
High Altitude Brewing: When brewing in higher
altitudes (5,000 feet), please enable the High
Altitude Brewing mode on your brewer. To enable
this mode, you will need to access the Technician
Menu.
Travel Mug Friendly: Remove the drip tray to
accommodate a travel mug.
Caring for your Brewer
Regular cleaning keeps your brewer running
smoothly. Always be sure to turn off your brewer
before cleaning. For detailed brewer cleaning
instructions and videos, visit commercial.keurig.com.
For service, please refer to the Warranty section.
K-Cup® Pod Holder Assembly and Needles
The K-Cup® Pod Holder Assembly (PHA) should be
removed from the Puncture Mechanism (PM) for
cleaning. To remove the PHA, remove the half rim,
then squeeze the two snap tips on the rear of its flip
seat to release.
The PHA can be cleaned by submerging it in Keurig®
Descaling solution, or a vinegar solution (1:3), for 12
hours or more. There may be residual coffee grounds
in the groove and the flip seat. If required, take a
cotton swab to clean the area. Thoroughly rinse the
PHA before restoring it into the flip seat, then to the
half rim to lock in place.
There are two sharp needles in the PM that puncture
the K-Cup® pod. The Entrance Needle is located
underneath the lid of the handle, and the Exit Needle
is inside the PHA. These needles may get clogged
over time due to the build up of scale or residual pod
ingredients.
