USER NOTICES (cont.) 00656.0000 This equipment is to be installed to comply with the Basic Plumbing Code of the Building Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation Manual of the Food and Drug Administration (FDA). ELECTRICAL REQUIREMENTS CAUTION - Do not connect the brewer to the power source until specified in Initial Set-Up.
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.
Momentarily pressing this switch initiates a brew cycle when the On/Lower switch is in the upper position. D. Hot Water Dispense Switch (Model SLF only) Placing the switch in the lower position dispenses hot water and at the same time refills the tank. Dispens- ing/refilling occurs for as long as the switch is held.
TROUBLESHOOTING A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encountered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department. • Inspection, testing, and repair of electrical equipment should be performed only by qualified service personnel.
