Unpacking Instructions
Carefully unpack the machine and inspect immediately
for shipping damage. The packaging may contain un-
attached parts. Your machine was shipped in a carton
designed to give it maximum protection in normal
handling. It was thoroughly inspected before leaving
the factory. In case of damage, contact the shipper, not
Grindmaster-Cecilware.
NOTICE: The person installing this appliance is
responsible for ensuring that electric and water
connections meet the requirements of the national
electric code, national plumbing code, and any local
ordinances.
The electric and water hook-up locations are behind the
front panel. Remove the four screws fastening this
panel for access to these connections.
Mechanical Installation
NOTICE: This brewer should be installed by a
knowledgeable and experienced commercial
equipment installer.
1. Inspect unit to see if any damage occurred in
shipment.
2. Remove the brewer from the packing material and
attach its legs.
3. Position the brewer on a strong, stable table or
counter.
4. With bubble level, check to see that the brewer is
level on countertop. Check the level front to back
and side to side. Adjust the legs to the correct level.
Water Hook-up
NOTICE: This equipment must be installed in
compliance with applicable Federal, State and/or Local
plumbing codes having jurisdiction. This product
requires an approved backflow prevention water
device, such as a double check valve, to be installed
between the machine and the water supply. Incoming
pressure should be greater than 30 psi and not more
than 80 psi (207-552 KPA).
1. The water line may enter through holes on the rear
or the bottom of the brewer. Use the right hand
opening for water.
2. Use 3/8" copper or flexible water line to prevent
strain. Do not use low temperature plastic tubing.
The connection to the fill valve is 3/8" flare.
3. Prior to installing the brewer, flush out the water
line by running approximately 1 gal. (4L) of water
into a pail. This will ensure no sediment from a new
installation can get in the brewer.
4. Water line pressure must be from 30 to 80 psi (207-
552 KPA).
5. Hot (up to 160°F / 71°C) or cold water may be used.
Hot water offers faster recovery between brews.
6. Make sure brewer is unplugged. Connect the water
line to the brewer with the hose connector.
7. Install a shut-off valve near the brewer.
8. Installing a filtering system can improve the taste of
brewed coffee and extend the life of the brewer. If
your water has high calcium (lime), chlorine, or iron
content, this is especially important. The filter
should be the lime inhibiting type if cold water is
used. Contact your local water treatment
professional regarding the type of filter you should
use based on water quality and volume of water
used.
Electrical Hook-up and Start-up Procedure
NOTICE: This equipment must be installed in
compliance with applicable Federal, State and/or Local
electrical codes having jurisdiction. Do not use
extension cords. Make sure that the outlet the brewer
plugs into is grounded.
The brewer is designed to operate at the specified
voltage on the nameplate with a tolerance of ± 10% for
voltage deviation. It is very important that the power
line to the brewer be checked to make sure that the
voltage is within 10% of the brewer’s rated voltage.
Failure to provide adequate voltage, as defined above,
will cause problems with your brewer. If the power is
too low, the solenoid valves may or may not work or
longer recovery time will be experienced. The brewer
may be permanently damaged if the voltage is too
high.
1. The electric ratings for your brewer are printed on
its nameplate.
2. The brewer should be connected to its own circuit
with a fused disconnect switch or a circuit breaker
near the brewer.
Important: For CE units, means shall be provided to
ensure all pole disconnection from the supply. Such
means shall be one of the following: a supply cord
fitted with plug, or a switch that is directly connected
to the supply terminals and has a contact separation of
at least 1/8” (3mm) in each pole.
3. Attach the appropriately sized cord to the brewer
with a cord grip for the 1 1/2” (3.8 cm) electric input
opening. The cord may enter through the rear or
bottom on the left side of the brewer. 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.
WARNING: ELECTRIC SHOCK HAZARD!
Installation of this appliance should be performed by
qualified service personnel only. Improper installation
could result in electrocution.

4. Standard connection is 1 phase 3 wire. Connect the
two lines to L1 and L2 on the terminal block. If the
brewer is wired for three phase, a lug, L3, is
provided on the terminal block. Neutral line should
be connected to the N terminal. Alternately, if no
neutral is available, the brewer can be wired
accordingly by connecting L1 to position marked
“L1” and L2 to position marked “L2”. This will
require the installer to change the connection to
the transformer primary from the white wire (120V)
to the blue (208V) or orange (230, 240V)
connection. See below. NOTE: This “no neutral”
conversion is only applicable to units marked as
208V, 230V, or 240V. It is NOT applicable to units
marked 120/208V or 120/240V.
Note: The brewer utilizes a multiple tap primary
transformer to convert line voltage to 24 volts for use
by the controller and some operating controls. The
transformer has taps for 120V (white wire), 208V (blue
wire), and 240V (orange wire) line voltage. Be sure to
connect the white wire from the terminal block to the
proper tap for the supplied voltage.
See diagram below.
5. The body of the brewer must be grounded. A
ground lug is provided for this purpose.
Note: If supply cord is damaged, it must be replaced by
a special cord or assembly from the manufacturer, or its
service agent.
Note: This appliance is IP10 rated, and shall not be
cleaned with pressurized water.

1. Flip power supply to machine “ON” at the branch
supply disconnect and allow the water tank to fill.
The machine will make a subtle hissing sound while
filling.
Note: A watchdog circuit monitors the fill valve “ON”
time. If the “ON” time exceeds 6 minutes continuously,
the brewer will display message “ER1” and cease
operation. Normal initial fill time on some models
exceeds 6 minutes. Turn off power to brewer and turn
back on; this will reset the controller and allow brewer
to complete filling.
2. Once the brewer is full, it will take 15 to 35 minutes
to heat. The ready lights will turn on when up to
temperature.
3. Insert the brew basket(s) and place a Shuttle or
airpot under the basket(s). Brew at least one batch
from each side. Check the level in the container to
be sure the brew volume is correct. Remember that
when using coffee, the level will be lower. Do this
for all batch sizes. The water must be hot to check
the levels. If adjustments are needed, see the
Adjustments section of this manual.

basket, ABB1.5, and 14 x 6” (36 x 15cm) for the
larger, ABB2.0.
4. Place ground coffee in the filter basket. Follow
corporate recommendations for amount of coffee
and grind. A full Shuttle is 1.5 gallons (5.7L). A full
vacuum Shuttle is 1.6 (6.0L) gallons.
5. Slide the basket into the brewer making sure the
spout lines up with the top of the Shuttle.
6. If ready lights are lit, press correct batch size button.
7. Brew spray time is about 4 minutes for a full
Shuttle. After the brew, allow the coffee to drip for
1 to 2 minutes. Ready light will flash during the
entire brew spray and drip cycle. Brew basket will
be locked in place until drip cycle is finished.
8. Dump the grounds from the basket and rinse for
the next brew. Coffee is ready to serve.
9. The Shuttle may be placed on remote warming
stations. Use caution when moving a full Shuttle.
CAUTION: HOT LIQUID HAZARD
Water used for brewing coffee is very hot. Use
caution when brewing, pouring, or transporting
coffee. Accidental spills may result in severe burns.

Control Features
Pre-infusion: Controls the initial coffee grounds wetting and the first dwell time after the initial wetting. Pulse
brews are the series of pulses after the Pre-infusion process. All pulse ON and OFF times are the same.
Brew Countdown Timer: After the start of a brew the LED display will countdown the remaining time left in
the brew process. The countdown will include all OFF periods programmed in the Pre-infusion and the pulses. At
the end of the brew time, the display will scroll driP, while the brew basket drains itself. At the end of the drip
cycle, the display will scroll donE for 30 seconds then turn off.
Energy Savings Mode: If enabled, when the brewer is idle for three (3) hours this feature will allow the water
tank to lower its holding temperature to 120°F. The display will scroll SLEEPIng while in this mode. To exit energy
savings mode press any button and the unit will start reheating to brewing temperature.
Copy-to-Left: On twin brewers, this feature allows you to copy the brew parameters programmed on a particular
brew portion on the Right side to the Left side.

PB330 & PB430 Shuttle®Brewers American Metal Ware 7
On twin brewers, the right side, Large portion button (top green button) gives the user access to the global
programming parameters of the brewer, such as; Tank Temperature, Energy Savings Mode, Enable/Disable Low
Temp No Brew, ON/OFF, Drip Time and Bypass Ratio. After the global parameters are set, the individual portion
brew parameters can be set. All other portion sizes (left and right) only access individual brew parameters to that
particular portion. Also, on twin brewers, the last program step in programming individual brew parameters
allows the operator to copy those brew parameters to the left side if “YES” is selected. If “YES” is selected, the
brew parameters that were set for the right side for that particular portion are copied to the left side. If “NO” is
selected, then the left side must be programmed separately.
To enter program mode:
Press the UP and DOWN arrows simultaneously for 5 seconds. Once in program mode, the green LED for each
portion’s size will flash.
To program the following items, press the Large, Right side portion button. (refer to Table 1)
1) Temperature Scale: Choose °F or °C
2) Set Water Tank Temperature: Choose between 170°F - 205°F
3) EnErGy mOdE: Choose YES or no
4) Ltn (Low Temp No Brew): Choose YES or no
• If YES, the brewer will only allow a brew to begin if the water tank
temperature is within 5°F of set point.
• If NO, the brewer will brew at any temperature.
5) DriP time: Choose from 40% to 80% of brew time.
This is the amount of time the brewer takes to completely drain the
brew basket after the brew valve closes. The factory default is 50%, so
if the brewer is set for a 1.5 gallon brew, without pre-infusion and
pulses, the brew basket will remain locked for 2 minutes after the brew
valve closes.
If, with coffee, the brew basket drips for longer than 2 minutes,
increase the setting to 60%, which will be 2:24 of drip time. The setting
increases by 5% increments; 12 seconds each.
6) rto (Set Bypass Ratio): Choose Std or Grm
• Choose Std if you are using the standard sprayhead.
• Choose Grm if you are using the gourmet sprayhead.
Bypass ratio is the last global program parameter to be set. The following are the individual brew portion
parameters.
Each portion button can have individual brew sequences.
7) Br time (Brew time): Choose between 0:01 to 6:00 minutes.
This time setting controls the brew volume. The brewer brews at a rate
of 1.5 gallons in four minutes (48 ounces per minute / 0.8 ounces per
second). The Large portion button is factory set to brew 1.5 gallons or
4 minutes of brew time. Adjust the brew volume to desired level. One
second of brew time will change brew volume by 0.8 ounces.
8) PrE inFuSion: Choose OFF to 2:00 minutes.
This is the amount of pre-infusion desired with the batch of coffee. If
no pre-infusion is desired then set to OFF.

User Lockout
User Lockout is achieved via the position of the LOCK
jumper on the board header. Locate the header on the
board (shown next column) and place the jumper in the
desired position. In the Locked position all menus in this
document are locked out, and the unit will only allow
brewing functions. There are two versions of the
header, 10 pin and 2 pin. Both configurations are shown
next column.
System Restore Function
This function will restore a Precision Brew®unit to its
original factory settings. To activate system restore,
power on the unit while holding in the DOWN button
on the keypad (use the keypad that controls the RIGHT
side for a double unit).
Continue holding the DOWN button and the display
will scroll “rEStorE” to indicate that a system restore is
about to happen. If the DOWN button is released at this
point, the restore is cancelled. If the button hold is
continued, the display will scroll “donE” to show
completion of a system restore.
Upon a successful restore, the original factory settings
will override all changes. The brew counters are not
affected.
Factory Specific Features
The following sections describe features that are not
intended to be used by the end user. These features,
instead, are intended to help American Metal Ware set
