FEATURE DESCRIPTION
This section describes the various features of the Café 98 Barista series coffee brewers. If you are
already familiar with these features, and would like to begin programming the brewer, skip ahead to the
PROGRAMMING INSTRUCTIONS section.
The Barista series by Café 98 incorporates the latest features in brewer control technology along with the
proven brewing system you have come to rely on. Although providing for enhanced functionality brewer
controls remain intuitive and setup of key operating parameters couldn’t be easier. Multiple brew times,
visa-brew delay, tank temperature set point, brew mode, filter parameters and more are all set from the
front control panel using a digital display for precise control. The following pages will explain the control
features and then step through the process required to program your unit.
Brew Time – The Barista series has two independently programmable brew times denoted Brew 1 and
Brew 2. Either of these brew times may be turned off or set for any amount of time between 30 seconds
and 6 minutes for ultimate flexibility.
Visa-Brew Time – Provides for additional time to flash brewing light after the water delivery portion of brew
cycle to allow for the coffee to finish draining from the brew basket. The flashing indicator light, and the
delay in the audible coffee ready signal, aid in preventing premature removal of either the brew basket or
the dispenser.
Water Temperature Set Point – Allows for digitally setting the temperature of the water in the brewers tank
system to any value between 170 and 205 Deg F.
Auto Arm – When enabled this feature ensures that the brewer is up to temperature prior to brewing to
ensure proper extraction is obtained. If the water temperature in the tank is below the water temperature
set point when the brew cycle is initiated the water delivery portion of the brew cycle is delayed. The
heating light will begin to flash indicating that the unit is in the brew mode but is not up to temperature. At
the same time the tank heater will begin heating and when the tank reaches the preset temperature the
brew cycle will resume. Auto arm may be overridden by pressing and holding the appropriate brew button
for several seconds until the brew cycle starts.
Pre-infusion mode – This mode delivers a small amount of hot water over the coffee grounds and then
pauses to allow the gasses in the coffee to escape and to allow the grounds to absorb the water before
continuing. After this pause the brew cycle resumes normally. Pre-infusion can yield better extraction
rates than normal brewing modes. The pause time is added to the brew and visa brew time. The pre-
infusion times are preset at the factory. Pre-infusion for Brew 1 and 2 may be turned on and off
independently.
Pulse Brew Mode – This mode cycles the valve on and off during the brew cycle. This slows the entry of
cold water into the tank and minimizes the mixing action caused by introducing a large volume of cold
water into the tank at one time resulting in an increase in brew temperature. The additional turbulence
and mixing created along with the increased temperature can result in higher extraction rates for the
coffee. The time set for pulse brewing should exceed the time set for brew time. The time difference
between the pulse brew time and the brew time is the amount of time available as off time. The difference
is divided equally and distributed throughout the brew cycle to provide a pulse after every 20 seconds of
brewing. Pulse brew mode for Brew 1 and 2 may be turned on and off independently.
Audible Alert Mode – Provides an audible signal when coffee has finished brewing notifying everybody
that fresh coffee is available. May be turned on or off and set for 1-9 beeps.
