PLUMBING REQUIREMENTS This brewer must be connected to a cold water system with operating pressure between 30 (207 kPa) and 90 psi (620 kPa) from a 1⁄2" or larger supply line. A shut-off valve should be installed in the line before the brewer. Install a regulator in the line when pressure is greater than 90 psi(620 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is 1⁄4" flare. NOTE - Bunn-O-Matic recommends 1⁄4" tubing for installations of less than 25 feet and 3⁄8" for more than 25 feet from the 1⁄2" water supply line. A coil of tubing in the water line will facilitate moving the brewer to clean the countertop. 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. As directed in the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate backflow pre vention to comply with federal, state and local codes. For models installed outside the U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area. Plumbing Hook-Up 1. Attach the female fitting from the short piece of tubing on the strainer assembly (supplied) to the water inlet fitting on the rear of the brewer. 2. Flush the water line and securely attach it to the flare fitting on the strainer assembly. 3. Turn on the water supply.

INITIAL SET-UP 1. Remove the top lid from the brewer. 2. Rotate the control thermostat knob fully counterclockwise to the “OFF” position and replace the top lid. 3. Insert an empty funnel into the funnel rails. 4. Place an empty dispenser on the brewer base. Be prepared to empty the dispenser during these initial steps. 5. Plug in the brewer, place the ON/OFF switch in the “ON” position, and momentarily press the START switch. Water will flow into the tank and dispenser for five minutes and forty-five seconds. Empty the dispenser when this first cycle stops and press the START switch again. Empty the dispenser when the second cycle stops and press the START switch once more. During the third cycle, the tank will fill to its capacity and the excess will flow from the funnel into the dispenser. Empty the dispenser when this third cycle stops. 6. Disconnect the brewer from the power source, remove the rear trunk panel, and turn the handle on the needle valve approximately one-quarter turn counterclockwise to enable the flow of dilution water. This valve is fully closed at the factory. NOTE - The next step requires the use of a stopwatch to calculate the amount of dilution water flowing from the nozzle in one minute. You’ll need to capture and measure the timed dilution water in a separate vessel than the one used for the water flowing from the funnel. 7. Place a vessel under the brew funnel to catch the brew water. Use a hose or other means to divert the water from the dilution nozzle to a separate container. 8. Connect the brewer to the power source. Simultaneously press the start switch to begin another brew cycle and start the stop watch. Place the ON/OFF switch in the “OFF” position at exactly sixty-seconds (one-minute). When the flow of water stops, measure the volume of the captured dilution water. It should be approximately twenty-two ounces. 9. If not, disconnect the brewer from the power source, and adjust the handle on the needle valve clockwise to decrease the amount of water or counterclockwise to increase the amount of dilution water as required. 10. Repeat steps 8 & 9 until the recommended dilution water volume (twenty-two ounces) is achieved. 11. Disconnect the brewer from the power source and reinstall the rear trunk panel. 12. Unplug the brewer, remove the top lid, rotate the control thermostat knob fully clockwise to the “ON” position and replace the top lid. 13. Empty the dispenser. 14. Connect the brewer to the power source and wait for the ready light to glow indicating the water in the tank has heated to brewing temperature (approximately 20 minutes). Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter. 15. Begin another brew cycle and measure the total water volume from the dispenser. It should be approximately 3 gallons and 12 ounces. (396 ounces). 16. If not adjust the timer as required. See Adjusting Brew Volumes. 17. Start, and measure another cycle. 18. Repeat steps 16-17 until the recommended total water volume is achieved. 19. The brewer is now ready to brew a batch of freshly brewed room temperature coffee. Page 6 10792 050405 ADJUSTING BREW VOLUMES CAUTION - Disconnect the power source from the brewer prior to the removal of any panel for the replacement or adjustment of any component. NOTE: Prior to setting or modifying batch sizes, check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server are in place. 1. Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the “SET” posi tion on the circuit board. To increase a batch size. Press and hold the START or BREW switch until three clicks are heard. Release the switch (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory) and press it again one or more times. Each time the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in order to verify that the desired volume has been achieved. To decrease a batch size. Press and release the START or BREW switch once for every two-second interval to be removed from the total brew time period; then immediately press and hold down the START or BREW switch until three clicks are heard. Release the switch. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). Allow the brew cycle to finish in order to verify that the desired volume has been achieved. 2. Setting batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the “SET” position on the circuit board. Press and hold the START or BREW switch until three distinct clicks are heard (approxi mately 10 seconds) and then release the switch. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). View the level of the liquid being dispensed. When the desired level is reached, turn the ON/OFF switch to “OFF” (lower). The brewer remembers this volume and will continue to brew batches of this size until the volume setting procedure is repeated. NOTE: When brewing tea, batch volumes will decrease due to absorption by the tea leaves. 3. Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times once programmed, you can set the SET/LOCK switch to the “LOCK” position. This will prevent any program ming to be done until switch is once again placed in the “SET” position. CLEANING CAUTION - Clean and sanitize your iced coffee brewer daily 1. Remove and thoroughly clean the entire brew funnel. The funnel must be free from any coffee particles or residue. 2. Disconnect the brewer from the power source. Remove and thoroughly rinse the sprayhead. Wipe the spray head panel clean with a damp cloth. 3. Insert the deliming spring into the sprayhead fitting until no more than one inch is visible and move it in and out 5 or 6 times. Insert the spring into the airvent hole in the sprayhead panel and move it in and out 5 or 6 times. Reattach the sprayhead. 4. Wash the entire outside surface of the brewer with a clean damp cloth. CAUTION - Do not keep brewed coffee overnight. The dispenser must be cleaned and sanitized daily.
