Installation  
WARNING  
ƽ
ELECTRIC SHOCK HAZARD!  
Installation of this appliance should be performed by qualified service personnel only. Improper  
installation could result in electrocution.  
Set-Up/Position  
1) Remove the brewer from the packing material and attach its legs.  
2) Position the brewer on a strong, stable table or counter. Check the level front to back and side to side. Adjust the  
legs to the correct level.  
IMPORTANT:  
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.  
Water Hook-up  
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) Water line pressure must be from 30 to 80 psi (207-2 KPA).  
4) Hot (up to 160°F/71°C) or cold water may be used. Hot water offers faster recovery between brews.  
5) Install a shut-off valve near the brewer.  
6) 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.

Shuttle Brewers & Airpot/Shuttle Brewers  
Installation (cont.)  
Electric Hook-up  
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 endure 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 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.  
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. A neutral line must be connected to the N terminal.  
Note: PB-xxxE 230V models are 1 phase, 2 wire or 3 phase, 3 wire and do not require a neutral.  
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, ot it’s  
service agent.  
Note: This appliance is IP10 rated, and shall not be cleaned with a water jet.  
WARNING  
ƽ
Never use the ground conductor as a neutral. This could cause electrocution.  
Start-up  
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.  
Attention: A watchdog circuit also monitors the water level in the tank and will disable the machine  
if the water level in the tank is not normal within (6) minutes of fill time. The machine will require  
power to be reset to clear the watchdog timeout and “ER-1” message will appear.  
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 baskets and place a Shuttle or airpot under the baskets. 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.

Operation  
CAUTION  
ƽ
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.  
1) Place an empty, warm Shuttle on the shelf, under the brew head. Turn on the warmer if available.  
2) If the Shuttle is not warm, allow the warmer to heat the Shuttle. Only a short brew of water will speed this.  
A cold Shuttle will significantly lower the temperature of the brewed coffee.  
3) Remove the filter basket and line with a filter paper. Paper size is 13 x 5 for the smaller basket, BB1.5, and  
14 x 6 for the larger, BB2.0.  
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.  
CAUTION  
ƽ
Coffee basket contains very hot water until the drip is completed. Early removal of a dripping  
basket could result in burns.  
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.

Adjustments  
All adjustments to machine are accessible through the front display(s). Refer to specifics below and the  
Programming Routine section. All values are preset at the factory and may vary brewer to brewer.  
Temperature Adjustment  
Tank temperature can be adjusted from 170°F – 205°F (77°C – 96°C) through the front display. See Programming  
Routine section for procedure.  
Brew Volume “br”  
Brew time can be set for each size visually. See Setting Brew Volume Procedure below.  
Brew time can also be adjusted through the display. See Programming Routine section.  
Setting Brew Volume Visually  
1. Remove brew basket and place container under brew head.  
2. Press and hold desired brew button for 5 seconds. Display will read “Pro”.  
3. Within 20 seconds, press and release desired brew button. Water will dispense from spray head and time  
will count-up in display.  
4. When volume is at desired amount, press and release brew button to stop flow. Time will flash in display.  
5. Within 20 seconds, press and release desired brew button. Display will clear and brew time will be stored  
into memory.  
Note: During this routine, no pulsing or bypass will occur.  
Note: If the On/Off button is pressed during procedure, time setting will default to previous time.  
Pulse Brewing “P-b”  
Within the Programming Routine, the number of pulses, pulse-on-time, and pulse-off-time for each size brew cycle  
can be set. During the pulse-off cycle, water shuts off to the coffee grounds. During this period, the grounds in the  
brew basket absorb water causing the coffee bed to rise. With a larger bed of coffee in the brew basket, remaining  
water from spray head has more contact area with grounds causing greater extraction of finished coffee.  
Note: Adjusting pulse values will not affect the finished brew volume. The brew time, however, will be automatically  
extended by the amount of total pulse OFF time.  
See Brew Routine Section for examples.  
Ratio “rto”  
The ratio of the bypass flow rate versus the spray head flow rate is factory set. This number, however, rarely needs  
to be adjusted.  
To find the proper value for the ratio:  
1. Within the Programming Routine, set the bypass % to the maximum number allowable.  
2. Remove the brew basket.  
3. Prepare two containers to measure volume from both the spray head and bypass.  
4. Press “Large” brew button to begin dispensing water.  
5. After a minute or two, cancel the brew cycle by pressing the “Large” brew button or pressing the On/Off button.  
6. Measure the volume of both containers.  
7. Divide the bypass amount by the spray head amount. This number is to be entered as the new ratio (ex. “.45”).  
8. Access the settings routine and adjust to the new ratio number.  
Note: If the ratio number is accurate, changing the bypass percent will not require resetting brew time.  
Note: Approximate ratio numbers:  
.45 for standard spray head models  
.64 for gourmet spray head models  
Shuttle Brewers & Airpot/Shuttle Brewers

Adjustments (cont.)  
Bypass “b-P”  
Brewer contains a bypass valve to control the amount of water to bypass coffee grounds and dilute the  
final brew. Bypass is available on Large and Medium brew cycles.  
Within the Programming Routine, the percent of the total brew volume to be bypassed can be set.  
Note: Adjusting bypass percent will not affect the finished brew volume. The brew cycle time, however, will be  
automatically reduced as bypass percent increases.

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 Grindmaster set up and test the machine.  
Factory/Field Test Menu  
This menu is intended to check product functionality both at the end of the factory line and in the field. The con-  
trol must be completely OFF (both sides) to enter field test. This mode is entered by pressing and holding the UP  
key and the LARGE BREW key on the keypad (use the keypad that controls the RIGHT side for a double unit)  
for 6 seconds. Once the menu is entered, the unit will start with an LED test that lights all LEDs and segments  
on the display.  
Proceeding through the field test is done by pressing the ON/OFF key (RIGHT side if a double unit). Each time  
this button is pressed, the test will advance to the next step. For the output test, use the UP and DOWN keys to  
select the desired output.  
Refer to the table on the following page for operation. Field Test Mode exits after stepping through all modes  
only- there is not a timeout.
