2 Water Supply Installation INSTALLATION (continued) INSTALLATION (continued) WARNING: SHOCK HAZARD Brewer must be properly grounded to prevent possible shock hazard. DO NOT assume a plumbing line will provide such a ground. Electrical shock will cause death or serious injury. IMPORTANT: Supply power must match nameplate for voltage and phase. Connecting to the wrong voltage will damage the brewer or result in decreased performance. Such damage is not covered by warranty. IMPORTANT: Do not connect brewer to electrical power until you are ready to fill the tank. See instructions on page 7. IMPORTANT: The ground prong of the plug is part of a system designed to protect you from electrical shock in the event of internal damage. Never cut off the ground prong nor twist a blade to fit an existing receptacle. Contact a licensed electrician to install the proper circuit and receptacle. GROUND PIN NEMA 5-15P NEMA 5-15R PLUG RECEPTACLE Fig. 3 Power Supply Plug ELECTRICIAN’S INSTALLATION INSTRUCTIONS REFER TO ELECTRICAL SPECIFICATIONS -Page 1 Check the nameplate to determine correct electrical service required for the Brewer to be installed. IMPORTANT: Before connecting to electricity, make sure brewer is connected to the water supply. All models are equipped with a cord and plug. They require a 115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire plus ground, with NEMA 5-15R or 5-20R Receptacle). See Figure 3 at right. 6 OPERATION OPERATION Fig. 4 Water Flow Diagram A. START-UP For initial start-up, or if the brewer has not been used for an extended period of time: ¦ Be sure spray disk and brew gasket are properly installed in the brew head. ¦ Be sure the water supply is properly connected and the water supply valve is turned ON and that TANK HEATER SWITCH is OFF before connecting brewer to electric power. ¦ Be sure the WATER TANK IS FILLED. IMPORTANT: Fill the water tank before energizing this brewer. 1. Connect brewer to electric power. Brewer will begin filling. When solenoid closes, tank is full. 2. Place an empty container in the hot water well. Press the HOT WATER DISPENSER BUTTON and dispense one cup of water. Tank should refill. Discard water. 3. Press TANK HEATER SWITCH to ON. 4. When READY light glows, brewer is ready to use. IMPORTANT: TANK MUST BE FULL OF WATER BEFORE CONNECTING BREWER TO ELECTRIC POWER. Heating elements will be damaged if allowed to operate without being fully submerged in water. Damage caused by operating the brewer without water in the tank is NOT COVERED BY WARRANTY. See page 8 for setting delivered water volumes for VOLUME SELECTION KEYS. 7 Fig. 5 Program Volumes OPERATION (continued) 8 B. PROGRAM BREW VOLUMES ¦ Each BREW VOLUME SELECT KEY is individually programmable. ¦ Keys may be programmed for pulse brewing to optimize contact times and extraction rates, or to minimize overflowing the brew chamber when using large amounts of grounds. ¦ Up to 10 pulses may be programmed. Each pulse delay is fixed at 15 seconds. 1. Place an empty airpot under the brew head. Install the brew chamber (without filter) under the brew head 2. Press and hold BREW key until beep sounds and the indicator lights flash. 3. Press and release the VOLUME SELECT KEY to be programmed. Water will begin to flow into the airpot. When the desired water level is reached, press the key again to stop the water flow. For pulse brew: a. Press the key to start the water flow. b. Press the key again to stop the flow after the time desired for the first pulse. c. Press the key again to resume water flow. d. Repeat until desired total delivered volume is reached. NOTE: Water flow can be stopped and restarted up to 10 times per brew. The delay between pulses is fixed at 15 seconds. 4. Press the BREW KEY to enter these settings into memory and resume normal operation. 5. Run a normal brew with filter and grounds to verify settings. Repeat steps 1 through 4 to program the other VOLUME SELECT KEY, or to revise existing settings. OPERATION (continued) 8 B.
