(“BUNN”) warrants equipment manufactured by it as follows: 1) Airpots, thermal carafes, decanters, GPR servers, iced tea/coffee dispensers, MCP/MCA pod brewers thermal servers and Thermofresh servers (mechanical and digital)- 1 year parts and 1 year labor. 2) All other equipment - 2 years parts and 1 year labor plus added warranties as specified below: a) Electronic circuit and/or control boards - parts and labor for 3 years.
INTRODUCTION The brewer incorporates a wireless interface system that allows the DBC Grinder to load certain information into the "programming chip" located inside the handle of the funnel. This information includes what flavor of coffee is being ground and what batch size will be brewed (small, medium, or large). Once the correct flavor name and amount of coffee is ground, the funnel is loaded into the brewer. The information from the funnel handle is then transferred into the brewer.
GLOSSARY AD CARD: An assembly consisting of a computer chip (TAG) and an instruction label. Used for loading advertising messages into the brewer. BREW LOCKOUT: The inability to initiate a brew if the water temperature is less than the ready temperature programmed into the brewer. BYPASS: The process of diverting a portion of the brew water to the outside of the paper filter so that it does not pass through the coffee grounds. This process is sometimes used to optimize the flavor of the finished brew.
PROGRAMMING Using the menu-driven display on the front of the brewer, the operator has the ability to alter or modify various brewing parameters such as brew temperatures, brew volumes, bypass percentages, etc. This allows for the precise brewing of various flavors of coffee. Programming of the brewer is achieved by entering a certain function. Then, by the use of hidden programming switches, the operator can customize the brewing process to their specifications.
PROGRAMMING THE BREWER The programming of the brewer is divided into two levels. There is one function in Level 1. All other functions are accessed in Level 2. The following function screens are in order of appearance. Each screen will have instructions on how to access, and the procedures to program the various functions of the brewer.
PROGRAMMING THE BREWER (cont.) RECIPE PROGRAMING METHODS METHOD 2: Using a RECIPE CARD to enter all of the brew settings at one time: If using a coffee name not in the grinder's memory, the customer can obtain a RECIPE CARD from the factory with all the information needed to set up that particular coffee name. This includes the COFFEE NAME, BREW VOLUMES, BYPASS PERCENTAGES, PULSE BREW TIMES, PREINFUSION TIMES, and DRIP-OUT TIMES.
