Adjustments

WARNING

Electrical Shock Hazard!

Dangerous electric voltages are present near adjustable components. All adjustments should be performed by qualified service personnel only.

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 time	=	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

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.
