INTRODUCTION This equipment will brew coffee into an awaiting server or airpot. The brewer may have an auxillary hot water faucet. It is only for indoor use on a sturdy and level counter or shelf. Please install in an area where there are no water jet devices.
USER NOTICES Carefully read and follow all notices in this manual and on the equipment. All labels on the equipment should be kept in good condition. Replace any unreadable or damaged labels. WARNING HAZARDOUS VOLTAGE DISCONNECT FROM POWER SOURCE BEFORE REMOVING! 12559.0003 #00986.0000 #00658.0000...
ELECTRICAL REQUIREMENTS WARNING - If the power cord is ever damaged, it must be replaced by the manufacturer or its service agent with a special cord available from the manufacturer or its service agent in order to avoid a hazard. Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit requirements.
NOTE - Bunn-O-Matic recommends 3⁄8" copper tubing for all installations from the 1⁄2" water supply line. A tight coil of copper tubing in the water line will facilitate moving the brewer to clean the counter top. Bunn-O-Matic does not recommend the use of a saddle valve to install the brewer. The size and shape of the hole made in the supply line by this type of device may restrict water flow.
OPERATING CONTROLS READY TO BREW ENABLE ENABLE ON / OFF ON / OFF WATER TEMP: 200° BREW BREW LARGE LARGE BREW BREW SMALL SMALL A. MAIN ON/OFF SWITCH This switch, located under the brewer in front of the right rear leg, turns power on and off to all components in the brewer.
INITIAL SET-UP Insert an empty funnel into the funnel rails of one of the 205° F (96.1° C) brew stations. Place an empty server under the funnel. Connect the brewer to the power source. Make sure the corresponding ON/OFF switch is ON (LED will be lit). Water will flow into the tank and stop when the tank is filled to its capacity.
1. Begin each brew cycle with a clean empty brew funnel. edge of filter 2. Insert a BUNN filter into the funnel. NOTE: The funnels are equipped with 4 wire loops that can be folded over top edge of filter if desired, to prevent filter from folding in during the brew cycle.
1. The use of a damp cloth rinsed in any mild, nonabrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment. Do NOT clean this equipment with a water jet device. 2. Check and clean each sprayhead. The sprayhead holes must always remain open.
GLOSSARY BREW LOCKOUT: The inability to initiate a brew if the water temperature is less than the ready temperature programmed into the brewer. BREW METER: The setting of a pulse brew routine by entering in the total desired water delivery time. The brewer will then calculate and perform a pulse brew routine using a predetermined formula.
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, pulse brew, etc. This allows for the precise brewing of various flavors of coffee. Programming of the brewer is achieved by entering a certain function.
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 for programming the various functions of the brewer.
