Description & Features

The CBS-2130 Series coffee brewers feature our universal spray over technology, which works like this:

The following variables are programmed for each batch size:

 Brew volume  Prewet percent (Percentage of the brew volume)

 Brew time  Prewet delay (The time between prewetting and the brew cycle.)

 Adjustable number of pulses  Bypass percent (Percentage of the brew volume)

 Three selectable spray patterns

 Drip delay (The time between the end of the brew cycle to

empty the brewbasket and end of the brewing cycle.)

Using these variables, the software calculates how much water to use for prewetting, bypass (optional), and brewing. The total brew time is divided into several cycles. Within these cycles, the software calculates how long to spray water over the coffee grounds, and how long to pause before the next cycle begins. The optional bypass valve opens at the beginning of the brew cycle and dispenses the correct amount of water all at once. Spray pattern into brew basket may be user set for perfect penetration.

Features

 Touchscreen Operation  Pump circuit calibration on startup  Cascading Spray Dome-no holes to clog in sprayhead  Magnetic flux brew basket sensor  Four fully programmable batch sizes per side  Dispenser locator under brew basket  Batch sizing  Brew at temperature protection  Customizable batch name  Brew mechanism is digitally adjustable  Recipe copy  Adjustable bypass (with bypass option)  Screen logo customizable by user from SD card  Three adjustable spray patterns  SD card firmware program and upgrade installation  Totalizing counters for brewer functions  User programs save to and load from SD cards  Shipped ready to operate out of the box

Installation

(For Qualified Service Technicians Only)

Guide to A Successful Installation

If not installed correctly by qualified personnel, the brewer will not operate properly and damage may result. Damages resulting from improper installation are not covered by the warranty, and will void the warranty. Here are the key points to consider before installation:

Electrical:

 All FETCO brewers require an electrical ground wire. Installation without grounding is dangerous.  Verify voltages, polarity, circuits, and circuit breaker access before attaching equipment.  The electrical diagram is located in the Users Guide and online at www.fetco.com.  The installation must comply with applicable federal, state, and local codes having jurisdiction at your

location. Check with your local inspectors to determine what codes will apply.

Plumbing:

 All installations must comply with applicable federal, state, or local plumbing codes.  An inline water filter is highly recommended. It should be installed after a water shutoff valve and in a

position to facilitate filter replacement.

 The water line and newly installed filter cartage must be flushed thoroughly prior to connecting it to the

brewer to prevent debris from contaminating the machine.

 Verify that the water line will provide a flow rate of at least 1½gpm/ (5.7lpm) per minute and water

pressure is between 20-75 psig (138-517kPa) before making any connections.

 Install a backflow prevention device if required. Many municipalities require a recognized backflow

preventer. Usable on all hot beverage and cold beverage equipment is a WATTS® SD-2 or SD-3. These spring loaded double check valve models are accepted by most zoning authorities. The check valve should be as close to the water supply inlet of the beverage equipment as possible.

General:

 Utilize only qualified beverage equipment service technicians for installation. A Service Company Directory is available at www.fetco.com.

Leveling legs, if installed, are to be adjusted for leveling the brewer only. Do not use for height adjustment, or extend them hi

WARNING

her than necessary.

Installation Instructions

Brewer Setup

1. Review the dimensions for the unit and verify that it will fit properly in the space intended for it. Verify that the counter or table will support the total weight of the brewer and dispensers when filled (specifics-page

3).

2. Place the brewer on the counter or stand.

3. When the brewer is in position, level it front to back as well as side to side by adjusting the legs.

4. For 200-240 volt units: remove the lower utility slide out at the back of the equipment to access the electrical connections. The utility slide must remain close to the unit, Note: it cannot be detached completely.

Connection

Water Connection

1. Water inlet is a ¼ inch male flare fitting.

2. The brewer can be connected to a cold or hot water line. Cold water is preferred for best coffee flavor, but hot water will allow for faster recovery times. High temperature water should not exceed 160°F/71°C.

3. Install a water shut off valve near the brewer to facilitate service. An in-line water filter should be used, it should be installed after the water shut off valve and in a position to facilitate filter replacement.

4. Flush the water supply line and filter before connecting it to the brewer.

5. Verify that the water line will provide at least 1½gpm/(5.7lpm) per minute for the CBS-2131& CBS-2132 and also that the water pressure is between 20-75 psig (138-517kPa).before connecting it to the brewer.

Electrical Connection – US & Canada

1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the brewer’s serial number label. Install an electrical ground wire.

2. The temperature and water tank fill level are pre-set at the factory. There is no need to turn off the heaters during the installation process. The heaters are disabled by the control board until the tank is full of water. The heating process will start automatically when the tank has filled.

3. Most CBS-2131 equipment is factory equipped with a 120 V cord and plug. Some CBS-2131 and all CBS2132 have a terminal block for connecting the incoming power wires. Consult local codes to determine if a cord and plug can be installed on factory supplied terminal block equipment, or if the unit must be hard wired.

4. Plug in unit if the equipment has an attached cord & plug, or, wire into circuit for terminal block units. Note that the plug is NEMA 5-15P or NEMA 5-20P (domestic).

5. A fused disconnect switch or circuit breaker on the incoming power line must be conveniently located near the brewer, and its location and markings known to the operators.

6. The body of the brewer must be grounded to a suitable building ground. A ground lug is provided in the brewer next to the power terminal block. Use 10 gauge copper wire for grounding.

7. Electrical connections must be secured in-place within the unit to meet national and local standards.

Warning : To prevent

electrical shock, this unit must be prope rly grounded.

Final Setup

1. Turn on incoming water supply line and carefully inspect both inside and outside of the brewer for leaks in all fittings and tubes

2. Turn on power.

3. Press the brewer’s main power switch (located on the lower right of the back of the equipment)

4. Pre-check will display: "DC voltage calibration for pumps is running…Please wait…Calibration is successfully done”. (15 seconds)

5. The water tank will begin filling. FETCO Home Screen #1 will read “FILLING”.

6. When the water level rises and is sensed by the probe at the top of the tank the heaters will activate

7. Heaters are automatically disabled until the tank is full.

8. While the water is heating Screen #2 “HEATING” will display and the actual water temperature will be displayed.

9. After the water has reached the set temperature Screen #3 will display “READY”

10. Review the Operating Instructions. Brew one full batch (water only) on each side to confirm proper fill levels. The brewer is factory set with water only (no coffee) to dispense the correct amount of water. If the actual volume is slightly different from the programmed volume, fine tuning the brewer may be necessary. See Calibrate Pumps in the OUTPUT section in the PROGRAMMING section.

11. Re-attach the covers after one final inspection for leaks. Look closely in the top of the brewer section at the dispense fittings during this inspection.

Operator Training

Review the operating procedures with whoever will be using the brewer. Pay particular attention to the following areas:

1. Always pre-heat the dispensers before the first use of each day by filling them half way with hot water, and letting them stand for at least 5 minutes.

2. Don't remove the brew basket from a coffee brewer until it has stopped dripping.

3. Make sure the dispenser is empty before brewing into it.

4. Show how to attach covers, close, and or secure the dispensers for transporting.

5. Show the location and operation of the water shut off valve as well as the circuit breaker for the brewer.

6. Steam from the tank will form condensation in the vent tubes. This condensation will drip into and then out of the brew baskets. Up to 1/4 cup/118cc discharging overnight is possible. Place an appropriate container under each brew basket when not in use.

7. We recommend leaving the power to the brewer on overnight. The water tank is well insulated and very little electricity is used to keep the tank hot. Leaving the brewer in the “ON” position will also avoid delays at the beginning of shifts for the brewer to reach operating temperature.

Cleaning & Maintenance After Each Brew:

1. Dispose of grounds and rinse brew basket.

2. Never strike a brewbasket or hit it against a hard surface.

This will damage the brew cone, and may damage the brewbasket support rails

3. Rinse dispensers before reuse.

Every Day:

1. Wash brew basket with hot sudsy water.

2. Pull CSD from the spray head, it is magnetically attached. Use gloves or a heavy towel. Æ Wash off any film and reattach. Use vinegar if limescale filming is present.

3. Clean dispensers with hot suds water and a brush, rinse and air dry.

4. Use only a soft cloth and hot suds on the outside to avoid scratches. Never use abrasives which will scratch surface.

Weekly

1. Use a commercial coffee dispenser cleaner such as URNEX™, TABZ™, DIP-IT™ or Squeak 'n Clean™.

2. Carefully Follow the instructions supplied with the cleaning product

3. Never use spray cleaners, solvent, solvent based cleaner or petroleum based polish anywhere on dispensers

Safety notes

1. Professional installation is required. This appliance is manufactured for commercial use only.

2. Operation requirements and maintenance for commercial cooking appliances differ from household appliances.

3. Operators must be trained for this equipment and must understand the use, maintenance and hazards.

4. Do not attempt to move hot beverage equipment once it is filled. Drain equipment before moving.

5. CBS-2130 series coffee brewers prepare up to 3 liters/1 gallon of coffee or tea in a single batch using very hot water. For safety, the brew basket is locked and may be serviced 5.5 minutes after starting the brew. The factory set brew (default) time is 5.5 minutes with the brew basket locked for safety from start of brew.

! Æ Never attempt to defeat or override a brew basket locking feature.
