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.
See rough-in drawings on previous page for dimensions
and locations of electric and water input.
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 back flow 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. 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) 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
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.
1. The electric ratings for your brewer are printed on
its nameplate. Typical electric ratings are:
Standard 120/208V, 5.0kW, 24A or 120/240V
6.6kW, 28A, 1 phase
Optional 120/208V, 3.8kW, 18A or 120/240V
5.0kW, 21A, 1 phase
If the brewer includes the three heater tank option
C21A, the ratings will be different. Always check the
nameplate for correct ratings.
2. The brewer should be connected to its own circuit
with a fused disconnect switch or a circuit breaker
near the brewer.
3. Attach the appropriately sized cord to the brewer
with a cord grip for the 1 1/2" 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.
WARNING: ELECTROCUTION HAZARD!
Never use the ground conductor as a neutral. Do not
use ground eliminating adaptors. Unit must be
properly grounded.

P300 & 400 Shuttle®Brewers American Metal Ware 5
Installation (continued)
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.
Start-up
1. Connect water line and turn water valve on. Check
for leaks.
2. Turn on the electric supply. The brewer will begin
to fill.
3. Replace the front access panel.
4. Once the brewer is full of water, it will take 15 to
35 minutes to heat. The “READY” LAMP will light
when water has reached the set temperature.
5. After “READY” LAMP is lit, portion volume may
now be checked. Insert the brew baskets and place
a shuttle under the baskets. Brew at least one batch
from each side. Do this for both batch sizes when
provided. The water must be hot to check the levels.
Remember that when brewing coffee, the level will
be lower. The water must be hot to check for proper
levels.
6. If adjustments are needed, see the Adjustments
section of this manual.
Operation
1. Place an empty, warm Shuttle under the brew head.
Turn on the warmer once a Shuttle is in place.
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 brew basket and line it with a paper
filter. Paper size is 13 x 5 for the smaller basket,
BB1.5, and 14 x 5 for the larger, BB2.0.
4. Place ground coffee in the filter basket. Your coffee
supplier can help you select the right amount of
coffee and grind. Coffee brewing experts
recommend between 6.5 and 8 ounces of coffee per
gallon of water for most applications. A full Shuttle
is 1.5 gallons.
5. Slide the basket into the brewer, making sure the
spout lines up with the top of the Shuttle.
6. Check that the correct batch size is selected. Check
the “READY” light. If lit, press START.
7. Brew time is about 4 minutes for a full shuttle, less
for half batches. After the brew, allow the coffee to
drip for 1 to 2 minutes.
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 adjustable components are located under the top
cover. To access these parts:
1. Shut off the electric line to the brewer or unplug
the brewer.
2. Remove the single screw fastening the top cover.
3. Pull forward and lift off the top cover.
Brew Volume Adjustment
The brew volume of the brewer is controlled by its
timer. The batch size is directly proportional to the timer
setting. The timer adjustment is located under the top
cover. On twin brewers, there is one timer for each brew
head.
Depending on the model, American Metal Ware offers
three types of timer adjustments. Look at the
instructions for the type of timer you have. There will
always be a small variation (± 5%) in level from batch
to batch.
Before making the timer adjustment, do the following:
1. Brew a batch of water to determine where the level
falls. Using a stop watch, determine the current
brew time. Measure the volume of water.
2. To determine the desired time setting, use the
following formula:
desired brew time = desired brew volume X current brew time
current brew volume
CAUTION: HOT LIQUID HAZARD
Do not transport brewer without draining water tank
first.
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.
CAUTION: HOT LIQUID HAZARD
Coffee basket contains very hot water until the drip
is completed. Early removal of a dripping basket could
result in burns.
WARNING: ELECTRIC SHOCK HAZARD!
Dangerous electric voltages are present near
adjustable components. All adjustments should be
performed by qualified service personnel only.

Timer Adjustment
Standard single batch timer: P models without half
batch include this timer, (see Figure A). This timer is
adjustable from 1 to 8 minutes. After removing the
cover, do the following:
1. Use the timer label to make an approximate
adjustment of the timer.
2. After adjusting the timer, brew a batch of water to
check the volume. Repeat adjustment, tweaking the
timer knob until the volume is correct.
Two Batch Timer with Knob Adjustment, See
Figure B:
1. This timer is adjustable from 15 seconds to 5
minutes. Locate the adjustment knobs under the
top cover.
2. Set this timer by adjusting the knob. The batch
selector switch picks the adjustment potentiometer
which the timer will see.
Two Batch Timer with Counter Adjustment, See
Figure C:
The two batch size timer may also be used with optional
counter potentiometer to ease adjustments. Each batch
size is adjustable from 00 to 99. The timer settings for
this timer are tabulated on the table below. This chart
is for making an approximate setting. You may need to
click up or down to make fine adjustments to volume.
Each number is about 3 seconds.

Adjustments (continued)
Bypass Adjustment
The bypass valve adjusts the amount of water which
bypasses coffee grounds and dilutes the final brew (see
Figure D). The factory setting is no bypass.
Bitter coffee results when the amount of ground coffee
is too small. Therefore, if your coffee is brewing too
strong, it is better to adjust the bypass valve instead of
reducing the amount of coffee.
To Adjust the Bypass:
1. Shut off and open brewer as described at the
beginning of the adjustments section.
2. Locate the bypass valve for the brew head you wish
to adjust. Valve is on the right and front of the
BREW valve.
3. Open the valve (counter clockwise) to increase
bypass percentage.
4. Measure the bypass setting:
a) Remove the brew basket.
b) Place an empty shuttle without its lid under the
spray head.
c) Place a measuring cup under the bypass nozzle.
d) Press START and brew water for about thirty
seconds or until measuring cup is almost full. Press
STOP.
e) Record the amount of water in the bypass
measuring cup.
f) Add this to the water in the shuttle and record,
measure the total amount of water.
g) The bypass percent is calculated as:
Bypass % = (Bypass Volume/Total Volume) X 100
5. Tweak the valve adjustment until the bypass is set
as desired.
Note: The bypass is accurate to ± 4%.
Thermostat Adjustment
The thermostat controls the water temperature in the
tank. Factory setting is 200°F. Water should never boil
in the tank. If water is boiling in the tank, adjust the
temperature appropriately.
Standard Mechanical Thermostat:
1. Shut off power and open brewer.
2. Locate thermostat mounted on tank. (Refer to
Figure E).
3. Turn the shaft counter clockwise to decrease
temperature, clockwise to increase temperature.
4. If the maximum temperature adjustment needs to
be increased, insert a small flat screwdriver into the
shaft. Turn the calibration screw counter clockwise
to increase the maximum temperature.
Optional Solid State Thermostat: This control
maintains temperature within 3°F. The adjustable range
is from 155°F to 205°F.
See Figure F.

Optional Solid State Thermostat Adjustment:
1. Shut off power and open top cover.
2. Locate thermostat on bracket mounted to front
panel.
3. Adjust the knob to the temperature desired. This
control cannot be set above 205°F.
Optional Brew Thermostat Adjustment: Your
brewer may include the optional low temp/no brew
thermostat, (see Figure G). This will not allow a brew
unless the water is up to temperature. The factory
setting is 192°F. If you wish to adjust this, do the
following:
1. Shut off power and remove top cover.
2. Locate the thermostat mounted on the water tank.
3. To increase the set point, turn the shaft clockwise.
We do not recommend adjusting this above 192°F
which may cause excessive delays between batches.
4. For accurate setting of the thermostat, remove the
bulb from the brewer and immerse in water known
to be 190°F. Adjust the knob so the thermostat
closes at this point.

After Each Brew:
1. Dispose of grounds and rinse brew basket.
2. Rinse Shuttles before reuse.
Every Day:
1. Wash brew basket with warm soapy water. The wire
basket is removable to aid cleaning.
2. Remove spray head(s) located above brew basket(s),
using gloves or a heavy towel. Wash off coffee oils
and clean any plugged holes.
3. Clean Shuttles with warm soapy water and a brush
or towel.
4. Wipe exterior of brewer with a damp cloth. Do not
use abrasives which will scratch surface.
5. If the Shuttle is to be left on the warmer all night,
fill it with water to avoid coffee oil burn-in.
Weekly or Bi-Weekly, Depending on Use:
1. Fill Shuttles with one gallon, 2/3 full, of hot water.
2. Pour the recommended concentration of urn
cleaner into the Shuttle liners (Excessive amounts of
cleaner will attack the stainless steel).
