Installation  
(For Qualified Service Technicians Only)  
Keys To A Successful Installation  
If not installed correctly by qualified personnel, the brewer may not operate properly and damage may result.  
Damage 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 electronic controls require at least 105 volts. Less than 105 volts will cause erratic behavior from the  
brewer. On 120/208-240 volt models, the #2 terminal on the terminal block provides power to the controls.  
The circuit breaker is located on the back of the brewer. To reset it, press and release the white button.  
The electrical drawing for the brewer is located on the inside of the lower cover.  
Plumbing:  
This equipment is to be installed in compliance 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-31, and ½ gallon per minute  
for the CBS-32 before connecting it to the brewer.  
General:  
Use 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. “Aap” model brewers are shipped with the legs attached. These legs are factory adjusted to one of two  
settings. One setting is for the 2.2 liter air pot (narrow).* The other setting is for the 3.0 liter air pot (wide).*  
The legs for the “A” model brewers are packed inside the brew basket, and must be attached by the  
installer. 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.  
Warning: Legs are to be adjusted for  
leveling the brewer only. Do not use  
for height adjustment or extend them  
higher than necessary.  
*Adjusting leg settings: Two holes are provided to adjust the width of the leg rails. Remove the ¼-20 allen head bolt with a  
3/16 allen wrench.and move rail to line up with desired hole. Fasten ¼-20 allen bolt. Repeat process on other side.  
Water Connection  
1. Water inlet is a 1/4 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-31, and ½ gallon per minute  
for the CBS-32, and that the water pressure is between 20 and 75 psig.  
6. 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 installation has been  
completed.  
5
Electrical Connection  
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. Only 120vac powered units are shipped from the factory with power cords and plugs attached. For other  
voltages, a terminal block is provided 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.  
Warning: To prevent  
electrical shock, this  
unit must be properly  
grounded.  
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 in accordance with applicable codes.  
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. Turn on the brewer’s main power 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.  
5. The heaters will be disabled by the control board until the tank is full.  
6. The brewer will be ready for operation as soon as the ready light comes on to signify that the water tank is  
up to temperature. The time required to reach brewing temperature will vary according to the electrical  
configuration ordered.  
7. 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.  
8. 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.

Operating Procedures  
1. Turn the power switch (A) to the on position  
The power switch will illuminate to indicate that the brewer has power and is operating.  
When the ready light (B) illuminates, the brewer is fully up to temperature. The amount of time  
required to gain full operating temperature will vary depending on the electrical configuration that was  
ordered, and the temperature of the incoming water.  
2. Prepare the brew baskets (F).  
Place a paper filter in each basket to be used. Pour the appropriate amount of pre-measured, ground  
coffee into the filter. The amount of coffee used will depend on your personal tastes and the  
recommendation of your roaster.  
Slide the brew basket back into the rails on the brewer.  
Select full or half batch mode (C) (optional).  
3. Prepare the dispenser(s).  
Ensure that the dispensers are empty. If you are using  
airpots, open the cover and remove the pump stem  
before brewing.  
Place the dispensers in position under the brew  
baskets.  
4. Press the brew switch (D) to start the brew cycle.  
The brew light (E) will illuminate, verifying that the brew  
cycle has begun.  
It is normal for the ready light to go out after the start of  
the brew cycle. On twin brewers, there is enough hot  
water in the brewer to support a second brew, even if  
the ready light is off. After brewing on both sides, you  
must wait for the ready light to come back on.  
Airpot  
Gravity pot  
The electrical configuration and the electrical power connected to the brewer will determine how long  
before the ready light comes back on for the next brew.  
If it is necessary to interrupt the brew cycle before it is finished, press the stop switch (G).  
5. You now have a dispenser of freshly brewed coffee, ready to serve, that will taste fresh and stay hot.  
ONLY a non-heated dispenser can do that.  
If you are using airpots, insert the pump stem before closing the cover.  
CAUTION:  
Do not remove the brew basket immediately after the brew cycle has finished. Wait until  
dripping from the bottom of the brew basket has stopped. Carefully remove the brew basket  
while inspecting the inside of the basket for hot coffee that has not finished draining.

Service  
Warranty  
All FETCO brewers come with a limited warranty. All warranty service must be pre-authorized by calling the  
FETCO Service Department at (800) 338-2699.  
Principles of Operation  
Fill System  
The fill system consists of a liquid level control board, a water level probe at the top of the tank, and a fill valve. As  
the water rises and touches the probe, continuity is established between the probe tip and the tank body, and the  
fill valve closes.  
When water is dispensed, the water level drops below the probe. After a 5 second delay, the fill valve opens until  
the water touches the probe again. The 5 second delay, and the speed that water refills the tank during brewing,  
results in many short bursts of water. The sound made by these repetitive bursts will let you know the fill system is  
functioning normally. (This sound may not be audible in a noisy environment.)  
The fill system is designed to protect the heaters during both the installation and a loss of the water supply. During  
initial installation, or whenever the power switch is turned on, voltage will not be supplied to the thermostat until the  
tank fills and water touches the water level probe. During operation, when water is dispensed and the water level  
drops below the probe, a fill signal is sent to the fill valve. If no water is sensed by the probe after 40 seconds, the  
voltage to the thermostat and the heaters is removed.  
Water enters the tank near the bottom. This introduces cold incoming water directly to the heaters and away from  
the dispense assembly.  
The water tank can be drained through a valve located on the back of the brewer, near the incoming water  
connection.  
Temperature System:  
The temperature system consists of an electronic thermostat, a temperature probe, and heating elements, and is  
enabled by the liquid level control board. (See the previous section - Fill System.)  
When the water level probe is in contact with water, power is delivered to the thermostat through the liquid level  
control board. If the temperature probe senses that the water is not hot enough, the thermostat energizes the  
heating elements through the mercury relay, the water is heated, and the ready light goes off.  
Once the water temperature reaches the set point, the thermostat disengages power to the heaters and the ready  
light illuminates. The thermostat is adjusted to 203° F ± 2° at the factory. (Slightly lower for high altitude  
installations.)  
Timing & Dispense System:  
The timing system consist of the timer, the dispense valve, the brew start switch, and the brew stop switch. When  
the brew start switch is pressed, the timer starts its’ cycle. The timer energizes the dispense valve, which opens  
and allows water to flow into the brew basket. It also lights the brew light. The valve remains energized throughout  
the brew cycle timed sequence.  
When the timer finishes its cycle, it removes voltage from the dispense valve. The valve closes, the flow of water  
stops, and the brew light goes out.  
The brew stop switch is used only when it is necessary to interrupt the brew cycle before the cycle is finished.  
The timer used with the half batch option has a small jumper wire on one end. A switch can replace this jumper to  
open or close this connection. Opening this connection cuts the timed output in half.

Adjustments  
Thermostat Adjustment:  
For equipment manufactured before April 2004  
The brewer’s water tank temperature is factory set at 203°F (slightly lower for high altitudes, to prevent boiling).  
This setting will deliver water at 195°F ± 5° to the coffee grounds.  
Measure the temperature by holding a thermometer in the stream of water flowing out of the hot water faucet. The  
temperature should be 195°F ± 5°.  
If an adjustment is necessary:  
Remove the upper cover of the unit.  
The thermostat is located in the upper section of the brewer. Locate the  
adjustment stem, which may be taped to the thermostat.  
Insert the stem into the adjustment hole.  
Turn the adjustment stem slightly counterclockwise (as viewed from the stem  
insertion point) to increase the temperature, and clockwise to decrease the  
temperature.  
Thermostat  
If you decreased the temperature setting, run 2 or 3 brew cycles to allow  
enough cold water into the brewer to lower the tank temperature.  
Wait for the “ready” light to come on, and measure the temperature again.  
Repeat until the desired temperature is obtained.  
Replace the cover(s).  
Effective April 2004:  
A new digital thermostat and temperature probe were introduced as a direct replacement for the old style  
thermostat and probe.  
During normal operation, the digital readout displays the last two digits of the actual water temperature. When the  
adjustment knob is turned, the readout begins flashing to indicate the set point, not the actual temperature. After  
the knob is released, the readout stops flashing and displays the actual temperature again.  
A red LED lights when the power to the thermostat is on. A yellow LED lights when the thermostat is calling for  
heat.  
To adjust, turn the adjustment knob. The display will flash, indicating that the display is showing the set point, not  
the actual temperature.  
Examples:  
The display shows only the last 2 digits  
of the temperature.

Timer Adjustment:  
For equipment manufactured before April 2004  
The timers control the amount of water that is used for brewing. The dual sided  
brewer, (CBS-32A, & 32Aap) has separate timers to control each side  
independently.  
All timers are factory set to deliver the correct amount of water.  
There are three possible types of timers used:  
Part # 51006 – full batch only (standard)  
# 51006 timer, 120V  
Part # 51005 – full / half batch (optional) The half batch setting provides  
exactly half the amount of water as the full batch setting.  
Part # 51017 – dual portion (optional) The timer has 2 independent settings.  
Adjustment of the factory settings may be desired to compensate for the amount of  
water absorbed by the coffee grounds. Approximately 2 ounces of water will be  
absorbed for every ounce of coffee.  
To adjust the timer:  
Remove the brewer’s upper cover.  
If your brewer has the half-batch or dual portion option, make sure the  
selector switch is in the full batch position.  
#51005  
timer, full/half, 120V  
Note the current setting of the dial before making any adjustments.  
Turn the knob clockwise to increase and counter-clockwise to decrease the  
timer setting. On the dual portion timer. the knob labeled “T1” controls the  
full batch setting.  
Run a full brew cycle to check the brew level.  
If necessary, repeat the adjustment until the desired volume is obtained.  
For the dual portion timer, set the selector switch on “half” and adjust the  
knob labeled “T2” until the desired volume of water is obtained.  
Replace the cover.  
#51017  
timer, dual portion, 120V  
Effective April 2004:  
A new digital timer was introduced as a direct replacement for the three old style timers. When a batch selector  
switch is not connected, the timer functions as a single portion timer.  
The timer has two independent settings, with three dials for each setting. The first dial in each group sets 100  
second increments, the second dial sets 10 second increments, and the third dial sets 1 second increments.  
A red LED lights when the power to the timer is on. A yellow LED lights when the timer is running.  
A small flat head screwdriver is required to adjust the dials.

Troubleshooting  
Brewing Problem  
Possible Cause  
Solution  
-Make sure power switch is on  
(Brewer lights are not illuminated) -Check power connection. (plug or hard wire  
connection)  
No power to the brewer  
Brew switch will not start brew cycle (no water  
is dispensed)  
and brew light does not come on,  
even when switch is pressed in.  
-Check the wall circuit breaker / reset  
-Reset the circuit breaker, located on the back of the  
brewer. Press and release the white button.  
Bad brew switch  
-Replace switch.  
Bad timer or stop switch. (The  
stop switch provides voltage to  
the timer.)  
-Check for voltage reaching the timer. If voltage is  
present, replace timer. If not, replace stop switch.  
and brew light does not stay on.  
(Light is on only while switch is  
pressed in.)  
No water reaching the brewer.  
Verify by dispensing water from  
hot water faucet for several  
seconds. Water should flow  
freely and steadily.  
-Make sure the shut off valve is open.  
-Check water line for kinks; replace line if necessary  
-Check to see if filter is clogged by changing it.  
Brew switch will not start brew cycle (no water  
is dispensed)  
and brew light does come on.  
Bad dispense valve. (Brewer may -Replace the dispense valve  
buzz when in brew cycle)  
Water filter clogged  
(See details in next section)  
Short brew levels EVERY BREW  
Dispense valve clogged  
Timer/s are set too low  
Incoming Voltage is too low for  
timers to function at proper time  
sequences  
-Clean and/or replace the dispense valve.  
-Advance timers to proper level.  
-Reset wall circuit breaker as one side may drop out &  
not flag the breaker.  
-Call an electrician to find loose connections in the  
building  
(One or both sides are affected and levels are  
consistent)  
Water filter clogged.  
-Replace water filter  
Short brew levels SOME BREWS  
(problem is worse during  
simultaneous brews)  
Weak dispense valve  
(may buzz during cycle)  
-Replace dispense valve.  
(One or Both sides are affected and levels are  
erratic)  
Water pressure or flow rate is too  
low or fluctuates too much to  
support a full brew.  
-Make sure brewer has a dedicated water line  
-Ensure that the shut off valve is open all the way  
(Never use needle saddle valves)  
(problem is worse during  
simultaneous brews)  
-Increase the diameter of the water line to the brewer  
and or find stable source.  
Brewer is not level  
-With an accurate level, level the brewer front to back  
and left to right by adjusting the feet.  
Brew time required to fill dispensers is not  
the same for both sides  
Timer/s are set too high  
Dispenser not empty  
-Adjust timers down to appropriate level  
High brew levels EVERY BREW  
(overfills but eventually does stop)  
SOME BREWS  
-Empty the dispenser and try again  
-Call FETCO Service Dept. to discuss.  
(800) 338-2699  
Brew basket or filter overflows  
Improper dose  
-Measure and confirm correct dose  
-Make sure only one paper is used  
-Adjust thermostat so the water stream measured at  
the bottom of the brew basket, 1/3 of the way  
through the brew cycle, equals 195 degrees + or - 5  
degrees  
Weak Coffee  
Too many filter papers  
Low brew temperature  
(Temperature inside the hot  
water tank should be set to 205°  
F.)  
Half batch used incorrectly  
-Use smaller brew basket  
Grounds not saturated  
-Discourage half batch use  
Water Softener in use  
Degassing - extremely fresh  
coffee  
-Move brewer water feed to a non-softened source.  
-Call FETCO Service Dept. to discuss.  
(800) 338-2699  
Dispense valve not sealing  
properly.  
-Clean, rebuild, or replace dispense valve.  
Spray head / brew basket drips - MAJOR or  
MINOR  
one side only  
Fill valve not sealing  
(Will drip even with power off.)  
-See next section - “Brewer won’t stop brewing”, “Bad  
or stuck fill valve”.  
Spray head / brew basket drips - MAJOR or  
MINOR  
double brewers - right side only  
14  
Brewing Problem  
Possible Cause  
Solution  
Water pressure over 75psi  
-Place a water pressure regulator on the line and reduce to  
20-75 psi  
Brewer won’t stop brewing  
(not the same as high brew levels)  
Water level probe bad or  
encrusted with lime.  
(causes brewer to continue filling  
hot water tank which will overflow  
into the brew baskets)  
-Clean lime build up on the probe tip  
and/or tank wall. (Holding the probe wire (green) from the  
probe end to the body of the brewer should stop the fill if  
the probe is bad but the liquid level board is good)  
Bad liquid level control board  
-Replace the LLC board if grounding the probe end of the  
(green) probe wire to the body of brewer does not remove  
the voltage at the fill terminal on the LLC board.  
-Rebuild or replace the fill valve if no voltage is on the coil  
(it is not magnetic) and it still passes water to the tank.  
(Disconnect the outlet side to see if it leaks water to the  
tank)  
Bad or stuck fill valve  
Reverse osmosis water system.  
(Mineral content is too low for  
liquid level control board to  
operate properly.)  
-Call FETCO Service Department to discuss.  
(800) 338-2699.  
Incorrect dosage  
-Measure and confirm the correct amount of coffee  
required  
Coffee tastes too strong  
Short brew levels  
-See “Short brew levels”, above.  
Temperature Problem (brewer only)  
See also dispenser problems  
Possible Cause  
Solution  
No power to brewer.  
-Make sure power switch is on  
-Check power connection. (plug or hard wire connection)  
-Check the wall circuit breaker / reset  
-Reset the circuit breaker, located on the back of the  
brewer. Press and release the white button.  
Brew water is cold / not hot enough,  
ready light is OFF.  
(Before proceeding, make sure water  
tank refills when water is dispensed.  
The brewer will not heat unless the  
tank is full.)  
Defective liquid level control  
board.  
(No power to thermostat).  
-With power on, and water tank full, check LLC board for  
120 volts on brown wire and neutral. Replace LLC board  
if there is no voltage.  
Bad connections on mercury relay. -Check relay for burned or loose connections. Replace  
(No power to heaters).  
Defective mercury relay.  
(No power to heaters).  
with high temperature connectors if necessary.  
-Check input and output voltages on relay. 120 volts on  
blue wire (input) but no voltage out to heaters indicates a  
bad relay.  
Bad heating element/s.  
-Check amperage draw on heater wires. 0 amps = bad  
heater.  
Bad Thermostat  
(the thermostat believes that it is  
at set temperature)  
-Replace the thermostat and or thermal probe. It’s not  
possible to trouble shoot the probe.  
Brew water is cold / not hot enough,  
ready light is ON.  
Low brew temperature setting on  
thermostat  
-See “Low brew temperature” under “Weak Coffee”  
section.  
Brewers with more than one  
heater can have just one fail.  
(CBS-32 - 120/220 volts only)  
Hot water tank limed up  
-Check amperage draw on heater wires. 0 amps = bad  
heater.  
Slow to recover temperature  
(Ready light takes a long time to come  
back on after brewing.)  
-Remove access cover to the hot water tank and inspect  
for lime. Remove the brewer for shop de-liming if build up  
is thick.  
Thermostat set too high for altitude -Reduce temperature setting to 3 degrees below boiling at  
Boiling and Steams  
(Denver etc.)  
your altitude  
Defective thermostat  
-Replace the thermostat and or thermal probe. It’s not  
possible to trouble shoot the probe.  
Dispenser Problem  
Possible Cause  
Solution  
Attempting to hold coffee  
too long.  
-Review discard times  
Coffee not hot enough  
Using 1/2 batch on regular  
basis  
-Encourage full batch use except at end of day or shift. Explore the  
need for smaller dispensers  
-Contact dispenser manufacturer:
