SET-UP AND POSITIONING OF BREWER
• Remove the brewer from packaging material and attach legs.
• Position the brewer on a strong, stable table or counter. Check the level front to back and side to side. Adjust legs as necessary to level
the unit.
WATER AND ELECTRICAL CONNECTIONS
IMPORTANT:THE PERSON INSTALLING THIS APPLIANCE IS RESPONSIBLE FOR ENSURING THAT ELECTRIC AND WATER
CONNECTIONS MEET THE REQUIREMENTS OF THE NATIONAL ELECTRICAL CODE, NATIONAL PLUMBING CODE AND ANY LOCAL
ORDINANCES.
The water and electrical connection locations are behind the front panel on the right side of the brewer. Remove the screws fastening this panel
to the unit to access these connections.
WATER HOOK-UP
• The water line may enter the brewer through holes in the bottom or rear of the brewer.
• Use 3/8” copper tubing or flexible water line to prevent strain. Do not use low temperature plastic tubing. The connection to the fill valve
is 3/8” flare.
• Water line pressure should be between 30 and 70 psi.
• Hot (up to 160°F) or cold water may be supplied to the unit. Hotter water will allow faster recovery between brews.
ELECTRICAL POWER SUPPLY HOOK-UP
• The electric ratings for this brewer are printed on the nameplate attached to the unit. Always see the name plate for rating information for
the particular brewer.
• The brewer should be connected to its own dedicated circuit with a fused disconnect switch or circuit breaker near the brewer.
• Attach the appropriately sized cord to the brewer with a cord grip for the 1-1/8” electric input opening in either the rear or bottom of the
unit. Use an oil resistant cord such as type SO, SOO, SAO, STOO, SEO, SJO, SJOO, SJTO, SJTOO, SJEO, HSO, HSOO, HSJO or
HSJOO. Alternatively, flexible conduit and type THHN wires may be used. Use only copper conductors.
• Standard units are single element units and are wired internally for single phase, 3 wire service. Connect the neutral line to the N terminal
of the terminal block and the 2 conductors to L1 and L2 of the terminal block. 3 element units may be connected to single or 3-phase
service. 3 element, single-phase units should be connected as described above. For 3 element units intended to operate with a 3 phase
power supply, connect the third phase conductor to L3 of the terminal block.
• The body of the brewer must be grounded. Connect the ground conductor to the ground lug located near the terminal block.
WARNING: ELECTRIC SHOCK HAZARD! Never use the ground conductor as a neutral. This could cause
electrocution.
INITIAL START-UP
• Turn on the water supply to the brewer. Check for leaks at the supply line to fill valve connection. Remove the controller cover panel.
• Turn on the electrical power. The brewer will begin to fill. Units that require more than 5 min. to fill will display an error message “ER1” on
the controller after 5 min. of filling. Press the SELECT button on the controller for 10 sec. to reset the unit and continue filling. To reset the
controller, the SELECT button must be pressed while the LED’s indicate ER1. If the SELECT button is momentarily pressed a timer
numerical value will be displayed. If this occurs, wait 10 sec. and the error message will again be displayed; press the SELECT button for
10 sec. to reset controller and resume filling.
• After the tank has filled, replace the controller cover panel.
• Turn on power and the water heating cycle will begin; it will take 15-35 min. to complete the heating cycle. The WATER HOT light on the
front of the unit will turn on when the water has reached temperature.
• The brewer can now be operated to evaluate brew timer settings and then make adjustments as necessary.
The brewer timers settings are preset at the factory to the following values:
Small brew
Medium brew (1.25 gal.)
Large brew (1.75 gal.)
(0.75 gal.)
120 sec.
165 sec.
230 sec.
• Insert the brew baskets and place the appropriate container under the brew basket.
• Portion size is selected with the touchpad located on the front of the brewer. The upper right hand area of the touchpad has 2 LEDs. If
both are lit the unit is set to brew the large volume. If only the upper LED is lit, the brewer will brew the medium volume; if only the lower

OPERATION
WARNING: WATER USED FOR BREWING COFFEE IS VERY HOT. USE CAUTION WHEN BREWING, POURING OR TRANSPORTING
COFFEE. NEVER ATTEMPT TO MOVE THE BREWER WITHOUT FIRST DRAINING THE WATER TANK. ACCIDENTAL SPILLS MAY RESULT
IN SEVERE BURNS.
ICB brewers will perform the brew function only when a container is properly located under the brew basket; the pushbutton switch must be
engaged to allow brewing. Removal of the container during a brew cycle will suspend the brewing cycle, however brew timing will continue to
elapse and the brew basket will continue to drip.
• Place an empty shuttle, airpot or insulated container on the shelf, counter, or accessory base (depending on model) under the brew basket.
A cold container will significantly lower the temperature of the brewed coffee. Turn on the warmer if a shuttle is used. If the shuttle is not
warm, allow the warmer to heat the shuttle. A short brew of water will quickly warm the container.
• Remove the filter basket and line with a filter paper. Paper size for each basket is shown below:
Basket
BB1.5
BB2.0
Paper Size (inches)
13 x 5
14 x 6
• Place ground coffee in the brew basket. Your coffee supplier can help you select the right amount of coffee and grind. Coffee brewing
experts recommend 6.5-8 oz. of coffee per gallon of water for most applications. A full shuttle contains 1.4 gal., a full airpot contains 0.8 gal.
and a full insulated container contains 1.75 gal.
• Slide the brew basket into the brewer, making sure that the basket spout is properly aligned with the container opening. Rotate the basket
locks into the locked or downward pointing position so that the basket can not be inadvertently removed.
• Select batch size through the touchpads. Check the WATER HOT light. If it is lit, press the START switch on the touchpad. If the WATER
HOT light is not lit, wait and press START when it has become illuminated.
• Brew time is about 4 min. for full shuttles and insulated containers, less for half batches and airpots. After the brew, allow the coffee to drip for
1-2 min.
CAUTION:HOT LIQUID HAZARD!: COFFEE BASKET CONTAINS VERY HOT LIQUID UNTIL THE DRIP-THROUGH IS COMPLETED. EARLY
REMOVAL OF THE BASKET COULD RESULT IN BURNS.
• Remove the brew basket, dump grounds from the basket and rinse for the next brew. Coffee is ready to serve.
• The shuttle may be moved to a remote warming station and the insulated container can be moved to a remote dispensing site.

STANDARD FEATURES
Three options are available on this equipment; these options are available independently of each other. The features are described below:
Pre-infusion: This option enables the brewer to wet the grounds and then have a dwell period before the brew cycle is completed. This option
causes the brew valve to open for a period of time, close for an equal period of time and then open again for completion of the brew. The preset
periods are, respectively, 15, 30 and 45 seconds for the small, medium and large settings. After this no-dispense period, the valve re-opens to
complete the remaining 82% of the cycle.
Low Temp, No Brew: This option inhibits the initiation of a brew cycle in the event that water temperature in the tank is more than 5°F lower than
the setpoint. In the event that the temperature is outside of the acceptable range, the WATER HOT light will be off. A brew cycle can only be
initiated when the light is on if this option is employed; attempts to initiate a brew when the light is off will be ignored by the controller.
Automatic Bypass: This option allows the brewer to provide for bypassing of the grounds only for the large portion size by signaling a solenoid
valve in the bypass circuit to open only when the large portion size is selected. The bypass amount is set by regulating the flow through the
standard manual bypass valve provided on all units (see Bypass Adjustment).
These features can be removed at no charge by ordering the following options:
ICB-400/300
Option 250 eliminates pre-infusion, lo-temp/no brew,
Option 251 eliminates pre-infusion,
Option 252 eliminates lo-temp/no brew,

ADJUSTMENTS
WARNING: ELECTRICAL SHOCK HAZARD! DANGEROUS ELECTRIC VOLTAGES ARE PRESENT NEAR ADJUSTABLE COMPONENTS.
ONLY QUALIFIED SERVICE PERSONNEL SHOULD MAKE ADJUSTMENTS.
Components for adjustment of brew volume/brew timing and of temperature are located behind the small access panel located in the right-side
brewing alcove on ICB units and on the front panel on Columbia units. Adjustment for bypass is under the top panel. To access these
components:
• Turn off electric power to unit at the main breaker assigned to the unit (or disconnect the cord where applicable) when removing the
top panel.
• Remove the screws fastening the appropriate panel to the body.
• Remove the panel.
TEMPERATURE ADJUSTMENT
Brew water temperature can be adjusted by turning the knob on the main controller located behind the controller access panel. Temperature
adjustment range is from 175°F to 202°F. Adjustment for temperature should be made after measuring the temperature of the water dispensed
from the brew head by the following procedure.
1) Remove sprayhead from brewer and set aside.
2) Place a container under the outlet.
3) Press START and, using a thermometer, measure the temperature of the water being dispensed.
4) If a higher temperature is desired, rotate the TEMPERATURE ADJUSTMENT knob clockwise. If a lower temperature is desired, rotate the
temperature adjustment knob counterclockwise.
5) If water temperature setting has been increased, wait until heater has cycled and then follow steps 3 and 4 again. If water temperature
setting has been decreased, brew a large portion of water and repeat steps 3 and 4.
6) Continue this procedure until desired brew temperature is achieved.
7) Replace sprayhead.
BREW TIMING/BREW VOLUME ADJUSTMENT
Brew volume is adjusted by adjusting the timer values of the controller (refer to Temperature and Brew Timing Controls). The brewer timers
settings are preset at the factory to the following values:
Small brew
Medium brew
Large brew
(0.75 gal.)
(1.25 gal.)
(1.75 gal.)
120 sec.
165 sec.
230 sec.
Before adjusting brew timing, brew a batch of water and measure the brew volume. Record this value.
To adjust brew timing:
• Remove controller access panel.
• If making timer adjustments on a twin brewer, slide the brewer selector switch to the appropriate position. On single brewers, the switch
should always be in the left position.
• Press the SELECT button momentarily; a LED will light up to indicate which timing selection is being displayed on the alphanumeric
display. The top LED corresponds to the small portion size, the middle LED corresponds to the medium size, and the lower LED
corresponds to the large setting. Note the timer value displayed. The new timing should be calculated by the following:
Desired Brew Time = Desired Brew Volume
X Current Brew Time
Current Brew Volume
• After selecting the appropriate side and portion timer, adjust the timer value to the desired value by pressing the UP or DOWN buttons on
the controller. Hold the button down until the desired value is displayed; then press the SELECT button on the controller.
• Brew a batch of water and measure volume dispensed. Repeat procedure as necessary until desired volume is dispensed.
• Replace access panel.

BYPASS ADJUSTMENT (Refer to Figure D)
The bypass valve adjusts the amount of water that bypasses coffee grounds and dilutes the
final brew. The factory setting is no bypass.
Bitter coffee results when the amount of ground coffee is too small. Therefore, if coffee is too
strong, it is better to adjust the bypass rate instead of reducing the amount of coffee.
NOTE: Always adjust bypass before adjusting brew time because bypass affects
brew rate.
• Turn off electrical power to brewer and remove top cover.
• Locate the bypass valve to be adjusted. The bypass valve is located to the right and in
front of the brew tee.
• Open the valve by turning the valve handle counterclockwise to the desired setting.

• Measure the bypass setting:
a) Remove the brew basket.
b) Place an empty shuttle (with lid removed) under the sprayhead.
c) Place a measuring cup under the bypass outlet.
d) Press START and brew water for about 30 sec. or until measuring cup is almost full.
e) Record the amount of water in the bypass measuring cup.
f) Add the water from the measuring cup to the shuttle; measure total volume and record.
Bypass % = (Bypass Volume/Total Volume) X 100
• Adjust the bypass valve setting and repeat measuring process until valve is set as desired.
