COMMERCIAL BARISTA DEC 2001

INTRODUCTION

The Commercial 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 volumes, 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 Volume The brew time has been converted to display brew volume during setting to allow for easier setting of the desired brew volume. Either of these brew times may be turned off or set for any volume between 30 and 255 ounces for ultimate flexibility. Actual volume delivered may vary slightly from the programmed volume due to actual brewing conditions. However the volume deliv ered will be consistent from brew to brew. Simply adjust volume up or down to compensate as you would do with a standard time setting.

Double Dump Valve Option without a corresponding increase in brew time. This will help to preserve the beverage quality on larger brew volumes.

Visa-Brew Time 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 between 170 and 205 Deg F. The heating circuit also incorporates a pulse heating circuit, which slows the heater as the set point is approached, to avoid temperature overshoot.

Auto Arm 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. When the tank reaches the preset temperature, the brew cycle will resume. Auto arm may be overridden by depressing the appropriate brew button for several seconds until the brew cycle starts.

Pre-infusion mode gasses in the coffee to escape and allows 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 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 ex ceed 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 available. May be turned on or off and set for 1-9 beeps.

Coffee Freshness Monitor set for 10 minutes to 2 hours. The last 10 minutes of the freshness time are counted down on the display and when the preset time is reached a beep is sounded and the coffee monitor light begins to flash.

Filtering Flow Rate The flow rates may be turned off or set for .25, .50, .75 or 1.00 gallon per minute flow rates. Note: A filter with a flow rate of 1 GPM minimum is recommended.

Filter Capacity may be turned off or set for one of the following available values; 0, 500, 1500, 2000 or 2500 gallons.

Number of Brews be reset. Using the brew buttons, first display “Clr” when in the program mode, then depress cancel.

Power Mode shutdown time. Available modes are normal, power save (standby) and power down. The modes are described below.

•= Power Save (Standby) - In this mode the tank temperature will be maintained at approximately 170 degrees when the set time has been reached. Brew 1 light will flash about once every 10 seconds to indicate unit is in power save mode.

•= Power Down - In this mode the tank heater element will be disabled when the set time has been reached. Brew 2 light will flash about once every 10 seconds to indicate unit is in power down mode.

SEQUENCE OF PROGRAMMING STEPS FOR THE BARISTA CONTROLLER
