PLUMBING REQUIREMENTS

The dispenser may be connected to a cold or hot water system (140°F Max.) with operating pressure between 20 and 90 psi (138 and 620 kPa) from a 1/2" or larger supply line. A shut-off valve should be installed in the line before the dispenser. 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 3/8" flare. Dispensers set up to deliver to 1.8 Oz./sec. (53.2 ml/sec) per dispense tip, require a water supply source that can deliver a minimum of 1.7 gpm (6.4 lpm) at the inlet fitting. Dispensers set up to deliver 2.6 Oz./sec. (76.9 lpm) per dispense tip, require a water supply source that can deliver a minimum of 2.4 gpm (9.2 lpm) at the inlet fitting.

NOTE: Bunn-O-Matic recommends 3/8" tubing from the 1/2" water supply line. At least 18 inches of FDA approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the dispenser will facilitate movement to clean the counter top. It can be purchased direct from Bunn-O-Matic (part number 00326.0000). Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser. The size and shape of the hole made in the supply line by this type of device may restrict water flow.

This equipment must 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).

SETTING DISPENSER FLOW RATE

The dispenser comes from the factory with flow restrictors in the mix chambers. With the restrictors in place the dispense rate is about 1.8 oz./sec (53.2 ml/sec) and is used primarily for cup at a time dispensing. The flow restrictors can be removed to increase the dispense rate to about 2.5 oz./sec (74 ml/sec) for larger volume dispensing (airpots, carafes, etc.).

Removing the restrictors:

1.Disconnect the dispenser from the AC power source.

2.Open the Product Cabinet door.

3.Remove the concentrate tube, vent line and grommet from mix chamber ports in side the product cabinet.

4.Remove the two screws that fasten mix chamber to the control panel.

FlavorGard™ Feature

FlavorGard™ is a patented feed back control loop that monitors the mixed product and adjusts the concentrate delivery rate to maintain a consistent mix profile, i.e. Flavor Profile. The system consists of a conductance probe mounted in the final stages of the mixing chamber, a metering pump with RPM sensor and a digital controller. Once you have completed the installation of the dispenser, entered the desired mix ratio for your concentrate, dispensed several cups of the mixed product, and are satisfied with the Flavor and Strength being delivered, simply enable FlavorGard™, (refer to FlavorGard™ in Programming the Dispenser).

The dispenser will automatically calibrate the system to all the factors that make up your particular mix profile, (e.g. water source, filtration system, Brand of concentrate and mix ratio selected, etc.).

NOTE: It is very important that you have dispensed enough product to insure that the dispenser is fully functional and you are satisfied with the Flavor Profile of the mix product before enabling FlavorGard™.

Once FlavorGard™ is enabled, the dispenser will continuously monitor the mix product as it is being dispensed and adjust the metering pump speed to maintain a consistent mixed product, thus eliminating factors such as (settling of the concentrate, tube wear, viscosity changes, liming, etc.).

The system is designed to work with in the range of variations that can be caused by these factors. The factory preset range is (+/- 10 %) and is adjustable to a Max of (+/- 15%). This insures that the FlavorGard™ system is not responding to factors that cannot be corrected by minor adjustments to the speed of the metering pump, (e.g. kinked hoses, low water pressure, severely worn tubes, empty BIB’s, etc).

NOTE: Changes to Concentrate Ratios or Dispenser Flow Rates will automatically disable FlavorGard™. You will need to re-enable FlavorGard™, once you are satisfied with the new Flavor Profile.

CLEANING & PREVENTATIVE MAINTENANCE

General Cleaning and Sanitizing Procedures

Note: The BUNN® Liquid Coffee Dispenser incorporates a “user selectable” rinse reminder feature, which lights the Rinse LED on the front panel and disables dispensing when it is time to rinse. See Programming Functions to activate this feature.

Daily: RINSING

1.Open the dispenser door.

2.Select Rinse on the Function Selector Switch and Run on the Mode Selector Switch.

3.Close the dispenser door.

4.Place a 1/2 gal (2 liter) container under the appropriate dispense nozzle or nozzles.

5.Pull Dispense Handle of the appropriate side or sides for approximately twenty seconds or until the hot water is clear or has no concentrate coloring in it.

6.Open the dispenser door, select Normal on the Function Selector Switch, and then close door.

Note: To clear the “Rinse” alarm, pull each faucet handle until the flow stops automatically (approx. 20 seconds for each tip). The “Rinse” alarm LED will turn off when the Rinse Procedure has been satisfied for both sides.

Daily: PARTS WASHING

1.Remove and wash the drip tray, drip tray cover, and cup tray in a mild detergent solution. Rinse thoroughly.

2.Wipe splash panel, area around dispense nozzles, door, and cabinet with a clean damp cloth.

Weekly: SANITIZING

1.Open the dispenser door.

2.Select Prime on the Function Selector Switch and Run on the Mode Selector Switch.

3.Remove the bag connector from the product box and disassemble or prop open the internal valve to allow free flow of product through the connector. NOTE: Cutting the mating fittings from an empty bag makes an excellent “free flowing” connector for this purpose.

4.Place the bag connector into a one-gallon (3.8 liter) container of warm soapy tap water 140°F (60°C).

5.Place an empty container under dispense tip and pull the corresponding Dispense Handle until the clean soapy water is dispensed from the dispense tip.

6.Repeat steps 4 and 5 with warm tap water 140°F (60°C) to rinse the soapy water from the pump tubing. Continue pulling the Dispense Handle until the water is clear, and no soapy water is being dispensed.

7.Prepare 2.5 gallons (9.46L) of sanitizing solution by dissolving 1 packet of Kay 5 sanitizer into 2.5 gallons (9.46L) of 120°F (48.9°C) water to ensure 100 ppm of available chlorine.

8.Again, repeat steps 4 and 5 with the sanitizing solution. Once sanitizing solution is being dispensed, stop pulling the handle and allow the solution to sit for 5 minutes.

9.Repeat step 6 to flush out the sanitizing solution from the pump tubing.

10.Remove the mating connector from the bag connector.

11.Reattach the bag connector to product box.

12.Select Normal on the Function Selector Switch and Run on the Mode Selector Switch.

13.Pull Dispense Handle until concentrate/water mixture appears. Then pour one 12 ounce (354.9 ml) glass of concentrate/water mixture and discard.

14.Repeat steps 1 through 13 for other dispense head.

15.Wipe internal and external surfaces with a clean, damp cloth.

19

34766 112502

 

REPLACING THE PUMP TUBING

The pumps and tubing used in the dispenser are designed to give maximum performance and long life. However, the tubes are a wear item and must be replaced periodically. How long the tubes last is dependent on usage and properties of the concentrate. Excessive wear will reduce the output of the pumps resulting in a weak mixed beverage. Bunn-O-Matic recommends replacing the Pump Tubing a minimum of once every 6 months or sooner if warranted.

Refer to the Tube Replacement Instruction on the Cabinet door for details.

1.Rinse the pump tubing with warm tap water (Refer to steps 1 - 5 of the Weekly Sanitizing instructions) prior to removing the tubes to avoid concentrate spills.

2.Loosen the thumbscrew securing the tubing retainer plate to the pump housing. Set it and the retainer plate aside.

3.Depress the tension screw and remove it from the notch in the pump housing, releasing the spring tension on the pump band.

4.Open the compression band and gently pull the pump tube from around the pump’s rotor.

5.Inspect the pump bands for signs of wear. Replace if necessary.

6.Apply lubricant (BUNN-O-MATIC part number M2548.1000) to the new pump tubing’s rotor side.

7.Insert the tube onto the mix chamber port, then wrap the new tubing around the pump rotor, making sure that the elbow and clamps end up on the bottom side of the pump housing.

8.Depress the tension screw and insert it in the notch in the pump body, reapplying spring tension on the pump band.

9.Replace the tubing retainer plate and tighten the thumbscrew.

10.Repeat steps 1 through 9 for the other pump.

CAUTION: The dispenser must be disconnected from the power source throughout these steps.

1.Disconnect the dispenser from the power source.

2.Shut off and disconnect the incoming water supply.

3.Remove the front splash panel.

4.Pull out drain tube to empty into a sink or a container with a minimum of five-gallon capacity.

5.Make sure drain clamp is closed. Then, remove drain plug.

6.Direct tube into sink or container and open drain clamp. Continue draining tank until ALL of the water is out. Be very careful with the draining water because it can be very hot.

7.Close drain clamp, insert drain plug, place drain tube back into machine, and replace splash panel.

Note: The dispenser must be refilled using the Initial Fill & Heat steps before reconnecting the power source.

Field Calibration of the Concentrate Pumps / Dispenser Flow Rates

The factory set Default Values for the Pump & Dispenser Flow Rates are very accurate and typically do not need to be field calibrated. However, if the mix ratio accuracy is ever in question, this procedure can be used to recalibrate the unit in the field.

Equipment Required:

50 to 100 ml graduated cylinder, with 1 ml graduations. 64 Oz (2000 ml) graduated container.

Remove the lower splash guard assembly to access prior to starting this procedure

NOTE: You can calibrate either the Concentrate Pump or the Dispenser Flow Rate independently. Simply scroll through the menu screen to the desired section and perform only those steps.

Calibrating the Left Side Dispenser

Concentrate Pump Calibration

1.Select PRIME on the Function Selector Switch. (refer to Priming the Concentrate Lines).

2.Place a container under the Left Dispense Tip and prime the concentrate lines until a steady stream of concentrate comes out the tip (approximately 10 seconds).

3.Stop the Priming and allow the tip to stop dripping. Discard the concentrate collected.

4.Select NORMAL on the Function Selector Switch.

5.Locate the programming module and use the Arrow Down key to scroll through LCD screens until CAL LEFT SIDE appears and press the YES button.

6.The CAL LEFT PUMP menu screen will be displayed. Place a 50 ml graduated cylinder under Left Dispense Tip and pull Left Dispense Handle momentarily. The dispenser will run the Left Concentrate Pump for 20 seconds and then shut OFF automatically.

7.Keep the graduated cylinder under dispense tip until all the concentrate has dripped out.

8.Measure the volume of concentrate collected in the graduated cylinder.

Acceptable ranges for the volume collected

Tubing Size

Volume Collected

3/16" tubing

40

- 47 ml.

1/8" tubing

17

- 22 ml

9.If the amount collected is not within the acceptable range, empty the graduated cylinder and repeat STEPS 6 – 8.

10.If the amount collected is still not within range, replace the pump tubing with a new Tube Kit, (refer to the

Tube Replacement Instructions).

11.When satisfied with the volume of concentrate collected, press the Down Arrow Key

12.The CAL LF PUMP VOL menu screen will be displayed. Use the (-) / (+) keys to adjust number displayed to the amount measured in STEP 8.

Field Calibration of the Concentrate Pumps / Dispenser Flow Rates

(Continued)

Dispenser Flow Rate Calibration

13.Press Down Arrow Key to display the CAL LF WTR FLO menu screen.

14.Place a 64 Oz (2000 ml) graduated container under Left Dispense Tip and Pull the Left Dispense Handle momentarily. The dispenser will dispense water for 20 seconds and then shut OFF automatically.

15.Keep the graduated container under dispense tip until all the water stops dripping.

16.Measure the volume of water collected in the graduated container.

Acceptable ranges for the volume collected

_____Dispenser Flow Rate___________

____Volume Collected____

1.8 Oz/sec (53 ml/sec) w/ flow restrictor

32

- 38

Oz, (946 - 1124 ml)

2.5 Oz/sec (74 ml/sec) w/o flow restrictor

46

- 52

Oz ,(1360 - 1538 ml)

17.If the amount collected is not within the acceptable range, empty the graduated container and repeat STEPS 14 – 16

18.If the amount collected is still not within range, inspect the dispense valves, tubing and mix chamber for lime, kinks or other obstructions.

19.When satisfied with the volume of concentrate collected, press the Down Arrow Key.

20.The CAL LF WTR VOL screen will be displayed. Use the (-) / (+) keys to adjust number displayed to the amount measured in STEP 16.

21.Press Down Arrow Key again to exit the CAL LEFT SIDE functions.

Calibrating the Right Side Dispenser

Repeat STEPS 1-21 above for the “CAL RIGHT SIDE” menus.

Field Calibrating the Empty BIB Warning

The dispenser will automatically turn on the Left or Right “REFILL LED”, see Operating Controls and Interface, when the corresponding BIB is Empty. The Refill message is triggered when the FlavorGardTM sensor reading drops below the minimum setting. The factory set minimum is 500 and should be correct for most locations. However, in some areas the hardness of the local water supply may effect this reading. If the Refill message doesn’t come on when the BIB is empty or the message comes on too early and there is still concentrate left in the BIB, use the following procedure to find the correct Empty BIB threshold.

Calibrating The Empty BIB Threshold

1.Remove the lower splash guard assembly to access the digital programming module with LCD display.

2.Open the cabinet door and set the Function Switch to the “Rinse” position. Close the door.

3.Place a large container under the Left dispenser tip, then pull and hold the left dispenser handle.

4.Hold the dispense handle long enough to rinse all the concentrate out of the mix chamber and for the Conductance reading to stabilize and stop dropping.

5.Record the nominal Conductance value displayed. (NOTE: It is typical for this value fluctuate (+/- 25) points about the nominal value}. This is the conductance reading of the water in your area.

6.Repeat steps 3, 4 & 5 for the Right dispenser.

7.Add 100 points to the larger of the Left or Right side Conductance value. This is the new Empty BIB threshold value for your dispenser.

8.Enter this new value into the Empty BIB Alarm threshold, see Programming the Dispenser.
