Filter Requirements
The Keurig B150 brewer system, when used with Direct Plumb accessory,
requires the use of a water filtration system to optimize the coffee flavor and
brewer reliability. Two mounting holes with screws have been provided on the
back of the brewer for this purpose.
Keurig requires the use of an external water filter such as the Omnipure
KQ8A to maintain warranty.
A filter kit (part number 5025) is available from Keurig. This kit contains a
Omnipure KQ8A filter, filter head, and mounting bracket.
NOTE: The KQ8A Filter assembly comes with 1/4 FPT ports for both inlet and
outlet and the plumbed water inlet to the brewer is 3/4 Male Garden Hose Thread
1/4 OD LLDPE (Linear Low Density Polyethylene) tubing is recommended (NSF
compliant) between the filter assembly and the brewer. NSF compliant fittings are
recommended such as High Density Polypropylene Type.
NOTE: NO PLUMBING CONNECTORS ARE PROVIDED WITH THIS
KIT.
All KQ8A filter cartridges must have a minimum of four gallons of water
run through it after mounting to the brewer and before they are connected to
the brewer’s Inlet Valve at the install location. This procedure will prevent
fine particles of carbon from entering and clogging the water inlet valve.
Filter Installation
1. Attach a ¾” female garden hose connection to ¼” FPT fitting to the Inlet
Valve
2. Mount the filter assembly to the brewer using the screws provided on the back
of the brewer and connect the filter’s Inlet Port to the water supply.
3. Flush the filter BEFORE connecting to the Inlet Valve.
4. Plug brewer into a dedicated GFCI outlet. If the electric circuit is overloaded
with other appliances, the circuit breaker may trip. If possible, the brewer
should be operating on its own circuit, separate from other appliances. Never
use an extension cord.
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.
IMPORTANT NOTICE
NOTE: FAILURE TO USE A WATER FILTER OR FAILURE TO
USE A WATER FILTER IN THE PRESCRIBED MANNER WILL
INVALIDATE THE BREWER WARRANTY.

Descaling Instructions for B150 Brewer with DPK
Minerals in drinking water build up on hot surfaces and can build to a point where fluid
flow is reduced and other normal brewer functions are hindered. When this occurs, the
brewer must be cleared of these deposits to allow normal brewer function.
Keurig recommends that the brewer be descaled every 6 months or as needed depending
on use and/or local water supply mineral content. Symptoms of scale build up are slow
brewing and/or short cups.
The following procedure outlines the steps required to prepare the brewer for the addition
of the descaling solution.
1. Unplug the brewer from AC Power Supply.
2. Disconnect or interrupt external water supply feeding the brewer.
3. Drain the Hot Water and Cold Water Tanks using the drain tubes, marked H and
C, located at rear of brewer per the draining procedure as shown below.
4. At the rear, left, top of the brewer locate and remove two screws which will allow
removal of the Top Cover and gain access to the internal Water Reservoir.

5. After removal of Top Plate, the Descaling Solution Access Port in the Water
Reservoir will be clearly evident as shown below.

6. Reconnect the brewer to AC Power Supply.
7. Proceed with descaling procedure as defined below:
De-Scaling Procedure
Preparation:
Prepare at least 40 ounces of a commercial citric acid descale solution. You will
also need a large ceramic mug (a paper cup is not suitable for this procedure) and access
to a sink for discarding hot liquid.
FILL AND CLEAN
1. Pour 40 ounces of descale solution into the Cold Water Tank through the Access
Port shown above and turn on the brewer – the brewer will automatically fill and
begin heating.
2. When the brewer display shows “Ready To Brew” place the ceramic mug on the
drip tray, select the largest brew volume, and press the Brew button
NOTE: Do not use a K-Cup portion pack
3. Once the solution begins to exit the brewer, lift the Brew Head Handle just
enough to halt the brew process and let the brewer sit for 40 minutes in this state.

4. At the end of the 40 minutes, lower the handle and the brewer should complete
the brew (do not be concerned if the brewer does not complete the brew). Pour
the dispensed liquid into the sink.
5. Shut down the brewer, disconnect it from AC power, and drain both (Hot and
Cold) water tanks using the drain tubes located in the back panel of the brewer.
CAUTION: Hot water will be exiting from the Hot Water Tank
6. Manually fill the Cold Water and allow to drain tank three times, using 40 ounces
fresh water per fill. Replace Drain Tube Plugs and Access panel.
7. Reconnect or resume city water supply and power up the brewer.
8. Once the brewer is filled and hot, conduct large volume “Water Only” brews,
with no K-cup potion pack in place, until all remnants of the descale solution are
not longer evident discarding all liquids into the sink. We suggest using the
largest brew size to speed the process. Remember to open and close the brew
handle between each cycle so the blue Brew lights will flash.
9. Place the brewer back into service.
You may need to perform additional rinse cycles if you notice any residual taste.

Draining Procedure for Hot Water Tank and DPK CWT
This procedure is to be performed prior to transportation of unit and when converting
brewer between Pour Over usage and Direct Plumb usage.
NOTICE
THIS PROCEDURE MAY RESULT IN THE RELEASE OF
WATER AT TEMPERATURES HOT ENOUGH TO RESULT IN
BURNS. DRAINING PROCEDURE SHOULD ONLY BE
PERFORMED BY TRAINED SERVICE PERSONNEL.
1. Disconnect the brewer from AC power and, if applicable, disconnect the Direct
Plumb Unit from water supply.
2. On rear of brewer locate Access Panel and remove securing screw.
3. Lower the appropriate tube, remove Plug and drain into appropriate sized
container. NOTE: Hot Water Tank contains ~ 31 oz of water, Cold Water Tank
contains ~ 35 oz of water.
4. Replace Plugs and Access Panel.
