Description & Features

The CBS-2030e and CBS-2030s series feature patented intermittent 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.)
	Bypass percent		Drip delay (The time between the end of the brew cycle
	(CBS-2031s & 2032s only)		and the unlocking of the brew basket.)
	(Percentage of the brew volume)

Using these variables, the software calculates how much water to use for prewetting and brewing. The total brew time is divided into several 30 second 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.

Features

All Models:		CBS-2031s & CBS-2032s Only:
Two fully programmable batch sizes per side		Magnetic brew basket sensor
	Adjustable prewetting cycle		Brew basket safety locks
	Electronically controlled hot water service		Adjustable bypass

Installation

(For Qualified Service Technicians Only)

Keys 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.

Here are the key points to consider before installation:

Electrical:

All FETCO brewers require NEUTRAL. Ground is not an acceptable substitute. Installation without neutral may cause damage to the electronic components.

The electrical diagram is located on the inside of the lower cover.

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:

This equipment is to be installed to comply with the applicable federal, state, or local plumbing codes.

The water line 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 at least ¼ gallon per minute for the CBS-2031, and ½ gallons per minute for the CBS-2032 before connecting it to the brewer.

General:

Utilize only qualified beverage equipment service technicians for installation. A Service Company Directory may be found on our web site, http://www.fetco.com.

Installation Instructions

Brewer Setup

1. Review the Dimensions for the unit you are installing. Verify that the brewer will fit in the space intended for it, and that the counter or table will support the total weight of the brewer and dispensers when filled.

2. The brewer’s legs are shipped inside the brew baskets. Remove the brew basket(s) and the coffee dispenser(s). Place the brewer on its back and screw in the legs.

3. Place the brewer on the counter or stand.

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

5.Remove the lower cover to access the water and electrical connections. Knock-outs are provided in the back and base of the brewer body for the connections.

Water Connection

1.Water inlet is a 3/8 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.

3.Install a water shut off valve near the brewer to facilitate service. If an in-line water filter is 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 ¼ gallon per minute for the CBS-2031, and ½ gallon per minute for the CBS-2032, and that the water pressure is between 20 and 75 psig.

5

Warning: To prevent electrical shock, this unit must be properly grounded.

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. Make sure the electrical service includes neutral.

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.The CBS-2031 is factory equipped with a 120 V cord and plug. The CBS-2032 has only a terminal block for connecting the incoming power wires. Consult local codes to determine if a cord and plug can be installed, or if the unit must be hard wired.

4.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.

5. 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 only 10 gauge copper wire for grounding.

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

7. Finally, connect the incoming power wires to the terminal block as shown in accordance with applicable codes.

		1.) This unit must be hard wired for 120/208-240 VAC.
		2.) Once the unit is converted to 120/208-240 VAC
		operation, it cannot be converted back to 120
		VAC operation.

Final Setup

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

2.Turn on the incoming power.

3.Press the brewer’s main power switch, which is hidden behind the front leg of the brewer. The control panel on/off switch will begin flashing. Press this switch.

4.Within 6 seconds, the hot water tank will begin filling until the water is sensed by the probe at the top of the tank. The display will read “FIL”. The heaters will be disabled by the control board until the tank is full.

5.While the water is heating, the display will read “LO” and the actual water temperature will be displayed. After the water has reached the set temperature, the display will be blank. There is no “ready” light.

6.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 #60 – 61 in the Advanced Settings & Diagnostics section.

7.Re-attach the covers after one final inspection for leaks. Look closely in the top of the brewer 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 15 minutes.

2.Don't remove the brew basket 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 thermal 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. 1/4 cup 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 will use very little electricity 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.

6.The STOP button will illuminate, and the selected BREW button will flash, indicating that brewing is in progress. All other BREW buttons will extinguish.

7.When the brew cycle is finished, the STOP button will extinguish and the BREW button will continue flashing, indicating that coffee may still be dripping from the bottom of the brew basket.

8.Before removing the brew basket or dispenser, visually verify that dripping has stopped.

Notes:

Preheat dispenser by filling at least ½ full with water at brewing temperature. Allow it to sit for at least 15 minutes before draining.
