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.
