Altitude Correction Chart 

Brew At Temperature
Ideal brew water temperature is 200°F/93°C. After brewing, brewers can take time to recover the hot water tank temperature and signal READY to brew. This is called “recovery time”. The lag in recovery time is caused by rapid brewing cycles in a rush, low power heating elements, low incoming electrical voltage, water supply temperature, even the barometric pressure.
Operators will adjust the “Brew At” temperature to allow the brewing at lower temperatures. This will allow a slightly faster recovery time and give a small increase in brew cycles per hour.
Reduced brew temperature will always compromise the quality of the finished brew and lower the temperature of the customers coffee.

← Faster brew cycle with reduced temperature Compromised Extraction	Correct brew water temperature → Proper Extraction

Error Codes		(From SERVICE – Page7)
DO NOT CLEAR ERROR CODES UNTIL ERROR IS IDENTIFIED AND CORRECTED àContact factory or specialized personnel for error codes
Code	Description			Possible Cause	Corrective Action
001	Software error-error on start up or corrupted software			Improper start-up or shutdown	Restart, if still fault: reload software
002	Internal flash corrupted internal data memory malfunction			Error found in cyclic redundancy check CRC	Restart, if still fault: reload software If not corrected: replace board
050	Short-circuit in temperature probe			Probe failure.	Replace probe.
051	Open temperature probe.			Bad probe connection, or probe failure.	Check all connections. Replace probe if necessary.
100	Initial Fill Error. Initial fill time took longer than expected after powering up.			Water supply flow rate is too low, fill valve is stuck, water line kinked or closed.	Reboot machine. If persists-investigate cause of low flow rate. (Clogged water filter, kinked line, stuck fill valve)
101	Error on refill-. Tank did not refill within expected time.			Water supply flow rate to hot water tank is too low, or fill valve stuck or damaged (SEE PAGE 13)	Check water supply line. Flow should be 20-75 psig, (138-517kPa) >1gal/3.8L/min Investigate cause of low flow rate. If the flow rate is in range-replace fill valve
200	Heating flatline-Tank is boiling			Heater is on, temperature is not rising/dropping	High elevation correction. Bad heaters or temperature probe or position
201	If the hot water tank heaters are turned on during a heating cycle and tank temperature is not increasing according to software logic and the tank temperature is below setpoint			1)  Failure of SSR, high limit, temperature probe, or heating element. 2)  Water being removed by hot water faucet during heating (control displays “heating”)	1) Test and check SSRs, high limit devices temperature probe. Check heating elements with current clamp, replace if necessary. 2) Advise staff to refrain from taking large amounts of water from hot water tank, especially during “heating”.
202	Heater Shorted or Stuck SSR			Heater is off and heating SSR is stuck “ON”	Check ohms on heater (15-60Ω). SSR may be stuck in ON mode-replace SSR.
255	Keyboard [HID] error (Human Interface Device)			Usually from longer than 10 seconds’ contact. Or faulty reassembly after service	Restart, if still fault: reload software. If mechanical: replace module
NO BSKT Insert Brew Basket				Brew basket must be in place This is a SAFETY FEATURE	Insert brew basket into brewer rails to enable brewer

How to calibrate the flow rate
Set the flow rates of the brewer valves to adjust for over or under potting.
Built-in algorithms in brewer controller software corrects brew parameter to customer preferences or to trim variations in flow control components The control software uses the new flow rate entered in the CALIBRATION screen to adjust and correct the amount of water delivered by the valve  Increasing the flow rate value DECREASES the volume of water dispensed
Decreasing the flow rate value INCREASES the volume of water dispensed
Flow rate adjustment will control all batches made by the valve. All batches on the side of the valve will be adjusted, (left or right)
-Obtain the VOLUME DISPENSED of water only, by brewing a batch without coffee or filter paper.
-Obtain the PROGAMMED VALUE of the same brew. This is displayed on the home screen in the batch box
-Obtain the CURRENT SETTING for the flow rate from the brewer. Do this by entering PROGRAMMING and Tap to “CALIBRATION” then, tap “Flow Rates” and then “Water Valves”. The valves flow rate is in the top right corner.
Using the values obtained above to obtain the new flow rate setting to correct the volume dispensed: Divide the volume dispensed by the programmed volume and then multiply by the current setting
VOLUME DISPENSED
PROGRAMMED VALUE
×CURRENT SETTING=NEW FLOW RATE SETTING
-Enter programming mode, tap to “CALIBRATION”
-Tap back to “Flow Rates” and then to “Water Valves”
-Enter the new flow rate into the calibration slider for the valve tested
Note: values for brewers set in gallons are in decimal format. Place all quantities in ounces and divide by 128 (One gallon =128 ounces) to obtain decimal format  1 ½ gallon=128oz+64oz=192 oz (in 1 ½ gal.) 192÷128=1.5 gal.

Brewer Setup
NOTE-Assemble legs immediately after unpacking the brewer and before connection to utilities
1) Attach legs

4” legs – 
Part number 1073.00007.00 
3 required for CBS-2252 
4 required for CBS-2251
Legs are sent from factory inside brew basket. Attach legs before installing
2) Attach water inlet adapter
Place rubber washer with screen in adapter. Hand tighten only-and 1/4 turn with wrench

Install the adapter on inlet valve first before attaching water line. Adapter is shipped in the brew basket The valve threads are 3/4″ BSP MALE THREAD and are not 3/4 garden hose fittings.
Use of any other connector to valve will damage the valve DO NOT use US dishwasher water adapter or US washing machine adapter for this connection.
The threads on the USA adapters are unusable for the valve TO PREVENT DAMAGE AND INSURE PROPER EQUIPMENT OPERATION
The inlet valve thread is 3/4 INCH BSP (British Standard Pipe).
This valve is not a standard USA washing machine or dishwasher thread (¾” GHT)
-Use only the plumbing adaptor kit included with this equipment. Use the gasket included in adaptor kit -Plumber’s tape is not recommended for the adapter to valve connection -Hand tighten adapter on valve with gasket, then very lightly wrench 1/4 turn to set
-DO NOT SUBSTITUTE FITTINGS FOR CONNECTING TO WATER SUPPLY
Damage to inlet valve from improper installation will void the warranty
NOTE: DO NOT TANK PLUMB DRAIN. DRAIN IS FOR SERVICE AND MAINTENANCE.
Installation Guide
(For Qualified Service Technicians Only)
General:

1. If not installed correctly by qualified personnel, the brewer will not operate properly and damage may result.
2. Utilize only qualified beverage equipment service technicians for service and installation.
3. Always have an empty dispenser under spray head of all coffee brewing equipment-including when at idle
4. Damages resulting from improper installation are not covered by the warranty, and will void the warranty.

Electrical:

1. All FETCO brewers require an electrical ground wire. Installation without grounding is dangerous.
2. Note Equipotentiality Terminal, if present, (To identify the terminals which, when connected together, bring the various parts of equipment or of a system to the same potential, not necessarily being the earth (ground) potential, e.g. for local bonding.)
3. Verify voltages, polarity, circuits, and circuit breaker access before attaching equipment.
4. Brewers in this series wire differently in regards to a neutral wire. Review the wire diagrams.
5. The electrical diagram is located in the User’s Guide and online at www.fetco.com.
6. Make sure of the tight grounding of the equipment and use the external ground bolt.
7. 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.

See wiring diagrams for connections
Plumbing:

1. North America: All installations must comply with applicable federal, state, or local plumbing codes.
2. All Others: The water and waste piping and connections shall comply with the International Plumbing Code 2003,
   International Code Council (ICC), or to the Uniform Plumbing Code 2003 (IAPMO).
3. Use an inline water filter for all beverage equipment.
4. Install the filter unit after a water shutoff valve and in a position to facilitate filter replacement.
5. 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.
6. Verify that the water line will provide a flow rate of at least 1½gpm/(5.7lpm) per minute and the water pressure is between 20-75 psig (138-517kPa) before making any connections.
7. Use a wrench on the factory fitting when connecting the incoming water line. This will reduce stress on the internal connections and reduce the possibility of leaks developing after the install has been completed
8. Install a backflow prevention device. Most municipalities require a recognized backflow preventer.
   Usable on all hot beverage and cold beverage equipment is a WATTS® SD-2 or SD-3.
   WATTS 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.

Tank Drain
The water tank must be drained before maintenance procedures, and when the unit is to be relocated or shipped

1.  Disconnect power and water to unit. DANGER: Insure that all utility connections to the brewer are broken.
2. Move the unit near a sink or obtain a container large enough to hold four gallons of water.
   Note: the hot water tank may hold more than four gallons.
3. Remove the front panel and tank cover and allow the tank to cool to a safe temperature
4. The tank drain line and clamp are located inside-under the hot water tank. Pinch the drain line clamp to close
5. Locate the fill valve against the back wall, using pliers, loosen the hose clamp and move it back over the tube.
   Note Do not loosen the hose clamp to the bottom of the hot water tank
6. Crimp the tube an inch or two away from the drain plug to prevent water from flowing and pull it off the valve.
7. Pull the tube end out of the brewer and position over sink or bucket.
8. Release the crimped tube and hose clamp and allow the water to flow into the sink or container.
9. Multiple buckets may be needed during the draining, see tank volumes below.

Brewer	Hot Water Tank Capacity	OPEN Leave open for use PINCH SHUT To drain tank & service brewer
CBS-2251 Single	6.3 gal 24 liter
CBS-2252 Twin	11.5 gal 44 liter

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. Do not 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/60 cc 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 brew basket or hit it against a hard surface.
   This will damage the brew cone, and may damage the brew basket 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. 
   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 that 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

Warning

1. Turn off power before any cleaning procedure, including wiping the exterior for appearance reasons.
2. Dry the exterior, especially the face panel, before turning on power.
3. Do not apply any type of spray cleaner on the face panel of this equipment.
