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 70 psi.
4) Hot (up to 160°F) 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. Contact your local water treatment professional regarding the type of filter you should use
based on water quality and volume of water used.

P400ESHP
Standard 440V, 12.5KW, 16.3A, 3 phase WYE
If the brewer includes the three heater tank option C21A, the ratings will be different. Always
see 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.
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.
5) The body of the brewer must be grounded. A ground lug is provided for this purpose.
Start-up
1) Turn on the water supply to the brewer. 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, it will take 15 to 35 minutes to heat. The water hot light will turn on
when up to temperature.
5) 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 both batch sizes when
provided. The water must be hot to check the levels. If adjustments are needed, see the
adjustments section of this manual.
WARNING
Never use the ground conductor as a neutral. This could cause electrocution.

Shuttle Brewers & Airpot/Shuttle Brewers
Operation
1) RAPS Brewers require the accessory warmer base placed over the pegs on the brew
shelf before brewing into a shuttle. Plug the base into the receptacle on the side of the
brewer. The receptacle is only energized when a shuttle is in place.
2) Place an empty, warm shuttle or airpot on the shelf, counter, or accessory base (depending
on model) under the brew head. Turn on the warmer if a shuttle is used.
3) 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.
4) 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 5 for the larger, BB2.0.
5) 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 1.4 gallons and a full
airpot is 0.80 gallon.
6) Slide the basket into the brewer making sure the spout lines up with the top of the shuttle
or airpot.
7) Check that the correct batch size is selected. Check the WATER HOT light. If lit, press start.
8) Brew time is about 4 minutes for a full shuttle, less for airpots and half batches. After the
brew, allow the coffee to drip for 1 to 2 minutes.
9) Dump the grounds from the basket and rinse for the next brew. Coffee is ready to serve.
10) The shuttle may be placed on remote warming stations. Use caution when moving a
full shuttle.
CAUTION
Coffee basket contains very hot water until the drip is completed. Early removal of a
dripping basket could result in burns.
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.

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. Remove the top cover.
3) Pull forward and lift off the top cover.
Brew Volume, Brew Timer
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.
Note: Always adjust bypass before adjusting timer because bypass affects brew rate.
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 volume.
2) To determine the desired time setting, use the following formula:
desired brew volume
desired brew time = _________________ X current brew time
current brew volume
Adjusting the Timer
Standard single batch timer: RAP and P models without half
batch include this timer, (see Figure 1). 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. Figure 1
Single Batch 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.
WARNING
Electrical Shock Hazard!
Dangerous electric voltages are present near adjustable components. All adjustments
should be performed by qualified service personnel only.

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.

Bypass Adjustment
The bypass valve adjusts the amount of water which
bypasses coffee grounds and dilutes the final brew
(see Figure 4). 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 the desired setting. Use the table below as a guide:
BYPASS SETTING BYPASS: % OF TOTAL BREW
closed 0
1 turn 8
2 turns 12
3 turns 22
4 turns 33
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 main thermostat adjusts the water temperature in the tank. Factory setting is 200°F. This
is the ideal temperature for brewing most coffee. Water should never boil in the tank. If water is
boiling, adjust the thermostat. There are two types of thermostats available. Mechanical is standard
and solid state is optional. See the adjustment instructions for the thermostat in your brewer.
Standard Mechanical Thermostat:
1) Shut off power and open cover.
2) Locate thermostat mounted on tank. See Figure 5.
3) Turn the shaft counter clockwise to decrease temperature,
opposite to increase temperature.
Figure 5
Mechanical Ther mo stat

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 ad just able
range is from 155°F to 205°F.
See Figure 6.
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.
Figure 6
Solid State Thermostat
Optional Brew Thermostat Adjustment: Your brewer may include the optional low temp/no brew
thermostat, (see Figure 7). 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.
