I.Operation

1.BrewerU Overview

The Keurig B3000 Brewer is a commercial single serve coffee brewer specifically designed to be used with the proprietary Keurig K-Cup® portion pack. Coffee beans or ground coffee cannot be processed in this brewer. It can be configured with a coin vend control unit and a platform cabinet for additional K-Cup disposal capacity. It consists of a dual water tank capacity system which allows for fast sequential brewing. The brewing temperatures, water volumes and brewing times are tightly controlled. The water temperature can be set between 192 to 187 degrees F. The default setting is 192 degrees F.

The Keurig K-Cup portion pack is punctured automatically on the top and bottom when loaded and the brew process is started through the Control Module interface. In the brewing process, pressurized hot water is processed through the K-Cup, brewing the coffee and then dispensing it. The B3000 automatically ejects the used K-Cup into an internal K-Cup bin located behind the cup/drip tray door before each use. This brewing system requires a water supply that is either plumbed or pumped from a bottle in order to operate. There is no pour over filling capability.

For coin vend operation, the optional coin changer accessory kit (Part Number 5557) is available for use in the United States and Canada. This kit accepts the Coinco Quantum XXQ-G700 Series Multi Drop Bus (MDB) unit. The Coinco unit is not provided with the coin changer accessory.

B3000 Brewer Water Flow Mechanisms

A schematic and legend showing the major components of the B3000 are provided (refer to page 8 and 9). The functions of these components are listed below.

1.Water filling – The B3000 is a direct plumbed machine. Municipal water is introduced to the unit through the inlet valve [X]. The supply water is then led to the cold water tank [BB] via the rigid plastic tube connected to the float valve [Y]. The cold water tank is allowed to fill approximately 16 ounces, (480 milliliters) and then the valve [X] is de-energized (closed) by the CWT float magnet proximity switch [Z] which controls the fill level. The proximity switch (located outside the tank) contains magnetically activated reed switch which is controlled by a float magnet (located inside the tank) that monitors the water level.

2.The Cold water Tank – The cold water tank [BB] functions primarily as housing for the secondary overfill protection device which is the float valve [Y] and provides the air gap necessary for back flow protection. If the normally closed inlet valve [X] were to fail open or otherwise be prevented from closing due to debris or CWT float magnet / switch failure, then the float valve [Y] would shut off the water supply once the water level rose to the level to activate the float lever. Back flow is prevented as the float valve inlet is approximately 1 1/4 inches (29 mm) above the over flow port in the cold water tank [BB]. The cold water tank also functions as the water supply reservoir for the brewing system. The water supply in the tank is fed through two check valve [M] and tubing to the two cold water pumps (CWP) [W] that supply water to the hot water tanks via the CWP elbow, CWP connectors, silicone tubing, multi-connector tee, and silicone tube.

3.The Hot Water Tanks – The water flows through the bottom tank and into the top tank via a seal assembly which includes two o-rings, a seal washer (between the o-rings), and the sealing cover. To allow the hot water tanks to fill, the vent valve [J] is energized (opened) to allow air to leave the system as the tanks are filled with water. Water delivered to the hot water tanks [TP] and [TB] is heated by the heating elements located inside the tanks. The only one heater at a time is allowed to energize and the heater in the top tank (brew tank) has priority. The water temperature is controlled by the thermistors [V] located in each tank. To control volume stainless steel conductive probes are used to sense the brew volumes of 4, 6, 8, and 10 ounces (120, 180, 240, and 300 milliliters). In order to brew the system is closed, vent valve [J] de-energized (closed) to allow pressurization.

4.The Puncture Mechanism – the mechanism [DD] consists of the K-cup holding and puncturing apparatus, a hot water delivery and brewed coffee path, and the hot water dispense valve [OO]. To brew coffee one lifts the handle to present the K-cup holder [AA]. A K-cup is placed in the holder and the handle is returned to the closed position. Upon closing the mechanism, the K-cup is punctured on the top first by the entrance needle [N] and then the bottom by the exit needle [P]. The holes created in the K-cup by the two needles are sealed about the needles by gaskets. Once the K-cup is in this ‘ready to brew’ state and a cup is placed on the drip tray, brewing can commence. To brew, the system is closed, vent valve [J] de-energized and the brew pump [G] is energized. The brew pump pressurizes the system to approximately 4 psi (27.6 kPa). The air is delivered to the top of the brew tank via a silicone tube by way of the filter tee [H]. The water in the brew tank is forced out of the tank through the integral brew tube [L] in the upper hot water tank cover. The water flows out of the top cover through a silicone tube to the entrance elbow which contains a check valve [M]. The water flows next trough the entrance needle, contacts the coffee grounds in the K-cup, and brewed coffee is delivered through the exit needle to the cup located on the drip tray.

60-200807-000, REV C

5. Dispensing Hot Water - To deliver hot water only, the system is closed, vent valve [J] is deenergized, and the hot water dispense valve [OO] is opened. Through a combination of the force of gravity and a pressure boost from the brew pump, water now flows from the lower hot water tank cover thru a silicone tube, the hot water dispense valve [OO], a silicone o-ring, seal cover, and the hot water trough. The water does not take the same path as in the coffee brewing process because the boost in pressure form the brew pump [G] is lower than the cracking pressure of the brew path check valve [M].

3.The Keurig K-Cup® Portion Pack

The Keurig B3000 Brewer may only be utilized in conjunction with the single serve portion pack called the Keurig K-Cup. The K-Cup is fitted with a paper filter that is heat sealed to the inside upper edge of the plastic cup.

Depending on the individual blend, up to approximately 9 to 14 grams of premium freshly ground coffee is added. The K-Cup is nitrogen purged to remove oxygen and heat sealed with a three ply foil lid to lock in freshness for at least 6 months.

During the brewing process water is introduced into the K-Cup under pressure via the entrance needle, located in the Puncture Mechanism Module. The hot water extracts the coffee and passes it through the filter paper. The exit needle, located on the outer edge of the K-Cup holder, allows the brewed coffee to be dispensed into a cup or mug.

Filter Requirements

The Keurig B3000 brewer system 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 recommends the Omnipure KQ8A filter. A filter kit (part number 5025) is available from Keurig. This kit contains a KQ8A filter, filter head, and mounting bracket.

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.

Getting Started

You will need several tools for the installation or servicing the B3000 brewing system. They are as follows:

Two Number 2 Phillips screw drivers (8” and 12”)

Pliers (Regular Adjustable and Needle Nose)

Wire Cutters

6 mm Nut Driver

Next:

a)Attach a ¾” female garden hose connection that will reduce to either a ⅜” or ¼” connection to the Inlet Valve.

b)Mount the filter assembly to the brewer using the screws provided on the back of the brewer.

c)Flush the filter BEFORE connecting to the Inlet Valve.

d)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.

De-Scaling Your Brewer

Mineral content in water varies from place to place. Depending on the mineral content of the water in your area, calcium deposits or scale may build up in your brewer. Scale is nontoxic, but left unattended, it can hinder brewer performance. De-scaling your brewer helps maintain the heating element and other internal parts of the brewer that come in contact with water.

The brewer should be de-scaled every 6 months to ensure optimal performance. It is possible for calcium deposits to build up faster, making it necessary to de-scale more often.

This brewer is equipped with sensors to detect when scale buildup is interfering with the performance of the brewer. When this is detected, the brewer will alert you to perform a de-scaling procedure by generating one of the following messages.

De-scale soon

De-scale now

NOTE: SAFETY GLASSES AND RUBBER GLOVES SHOULD BE WORN BEFORE PROCEEDING WITH THE DE-SCALING PROCEDURE.

5.De-Scaling Procedures:

a)PREPARE

1.Make sure you have at least (80 ounces) of full strength citric acid such as CDCC Citric Acid Powder or similar product on hand. You will also need an empty sink and a ceramic cup (do not use a paper cup.) and a Flojet pump or similar.

2.Disconnect the brewer from the water supply and power it off. Drain both the hot and cold tanks.

b)FILL AND CLEAN

1.Enter the PRIME mode (enter Menu mode and answer YES to HAS BREWER BEEN DRAINED) and use a Flojet pump system to add de-scaling solution to the brewer.

NOTE: The water temperature for dissolving the powder can not be greater then 110° F. Damage to the Flojet pump can occur.

Complete the PRIMING process.

2.After it has primed and heated, place a ceramic cup in the Drip Tray and run a brew cycle. DO NOT USE A K-CUPP® Pportion pack, just press the Brew Button. Pour the contents of the cup into the sink.

VII BIT Testing

Manufacturing Built In Test (BIT)

The B3000 brewer has the ability of performing diagnostic tests to verify if most of the critical system elements are functioning properly. For brewers from 1 – 7505 see page 85. For brewers 7506 and above see page 89.

To initiate the B3000 BIT, follow the procedure below:

Start with an empty, cold brewer

While powered off; Press and hold the Menu Button

Turn power on (Hard Power)

Release the Menu Button

Press the Center Left Button 4 times within 2 seconds of applying power

Notes:

The top line of the display shows: o The test number

o The tested component / instructions

The second line of the display shows: o The most likely module bad, if fail.

For example

01: LEFT SW & LED MODULE: CTRL-PCB

If any test fails the criteria, BIT will halt at that failed test number

Ensure that the Entrance Needle is blocked before the start of the test with a pressure gauge. If not, BIT cannot advance beyond Test No. 22.

These test fixtures are required:

Plug in coin IF loop back plug. (Figure 1) (Use P/N 03-200922-000 for ordering) Ampere meter for power. (optional, can ignore current draw check)

Entrance needle blocker with pressure gauge. (optional, can use a piece of plugged tubing) Coin interface loop-back plug (short transmit to receive) (optional, can stop at this test) Vent clamp (optional, can use finger to block tube opening)

Inlet valve plug (optional, can use normal water hook-up)

Note that after a few passes of the BIT, the brewer will be too warm to pass the temperature sanity check.

BIT loops on the last test forever. Power down to continue.
