PLUMBING REQUIREMENTS

This dispenser must be connected to a cold water system with operating pressure between 20 and 100 psi (138 and 690 kPa). This water source must be capable of producing a minimum flow rate of 4.5 fl. oz. (133.1 ml) per second. A shut-off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is .25" (9.52 mm) flare.

NOTE - At least 18 inches (457 mm) of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the dispenser will facilitate movement to clean the countertop. 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.

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 prevention 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.

NOTE - If a backflow prevented is required by code, a shock arrestor should be installed between backflow preventer and dispenser. Installing the shock arrestor as close to the dispenser as possible will provide the best results.

NOTE - Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed and maintained in accordance with federal, state and local codes.

PLUMBING HOOK-UP

INITIAL FILL & HEAT

1. Turn on the water supply and connect the dispenser to the power source.

2. Water will automatically flow into the tank to the proper level and then shut-off. This will take less than ten minutes.

3. A tank full of cold water will take approximately fifty minutes for the water to heat at 120 volts, approximately

15 minutes at 240 volts.

4. Fill the hoppers with the dry product to be dispensed. Hot chocolate in the left hopper, powder milk product in the right hopper.

5. The LED display on the control panel behind the door splash panel will alternately display the tank water temperature and the cold shoe temperature.

LIQUID LEVEL CONTROL

The system automatically maintains the hot water tank’s level by energizing the refill solenoid when the water level drops below the liquid level probe. If the system has not successfully refilled in 15 minutes, a refill error occurs. When a refill error occurs, the refill solenoid is de-energized. Once the cause of the refill error has been investigated and cured, the system can be reset by both disconnecting (for at least 5 seconds) and then reconnecting the power to the machine.

RINSE ALARM FEATURE

Periodic rinsing of the mix chambers and dispense tips is essential for proper maintenance and optimum performance of the dispenser. The dispenser is shipped from the factory with the rinse timer enabled.

The rinse timer automatically keeps track of the time since the dispenser was last run through a rinse sequence.

If the dispenser detects that a rinse sequence has not been run for the desired time, all LEDs’ on the membrane switch on the front door will flash, and "RINSE" will be displayed on the LED display behind the door splash panel.

Rinse Procedure:

1. Open the front door and place the Normal/Program/Rinse switch in the RINSE position.

2. Place a large container under the dispense nozzle. Press any dispense button on the front door. The LED display above the programming buttons will begin counting down from 8. The rinse will terminate when the display reaches “0”.

3. Return the Normal/Program/Rinse switch to the NORMAL position, and close the front door.

EMPTY PRODUCT WARNING

The dispenser will automatically illuminate the LED next to the Decaf or Hot Chocolate button when the Decaf or Regular coffee BIB is empty, respectively. The Refill message is triggered when conductance sensor reading drops below the minimum setting. The factory set minimum is 450 and should be correct for many locations.

However, in some areas the hardness of the local water supply will affect this reading. It is recommended that the Empty Product Threshold be calibrated upon installation for proper operation of the Empty Product Warning.

See "Field Calibrating the Empty Product Warning" in the Calibration section of this manual.

Field Calibration of the Concentrate Pumps, Dispenser Flow Rates, and Hopper Powder Throw

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 or 100 ml graduated cylinder, with 1 ml graduations.

1000 ml graduated container.

NOTE: You can calibrate either the Concentrate Pump, Dispenser Flow Rate and set the Hopper Throw Rate independently. Simply scroll through the menu screen to the desired section and perform only those steps. (Refer to Calibrating the Dispenser)

Calibrating the Concentrate Pumps.

Decaf Coffee - Concentrate Pump Calibration

1. Open the door of the dispenser and select PROGRAM on the Mode Selector Switch.

2. Depress and Hold the MENU switch for approximately 10 sec. The unit will display “C1 run” when it has entered the Calibration Mode.

3. Select PRIME on the Function Selector Switch.

4. Remove the elbow from the Left (Decaf) Coffee Mixing Chamber and place a container under the mixing chamber outlet. Press the SMALL cup button. The dispenser will display a 100 count down and then shut the pump OFF automatically. Release the dispense switch.

5. Stop priming and allow the tip to stop dripping. Discard the concentrate collected.

6. Place a 50 ml graduated cylinder under the Left (Decaf) Coffee Mixing Chamber outlet.

7. Press the SMALL cup button. The dispenser will display a 100 count down and then shut the pump OFF automatically. Release the dispense switch.

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

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

The acceptable range for the volume of concentrate collected is 40 - 48 ml

10. If the amount collected is not within the acceptable range, empty the graduated cylinder and repeat STEPS

6 – 9.

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

Tube Replacement Instructions).

12. When satisfied with the volume of concentrate collected, press the MENU switch. The current Calibration volume “C1 XX” will be displayed.

13. Use the (-) / (+) keys to adjust number displayed to the amount measured in STEP 9.

Regular Coffee - Concentrate Pump Calibration

Depress the MENU button to display the Regular Concentrate Pump calibration menu “C2 run”. Repeat STEPS

3 – 13 above for the right side “Regular” pump, using the LARGE cup button.

Calibrating the Dispenser Flow Rates

Decaf Coffee - Dispenser Flow Rate Calibration

1. Select RINSE on the Function Selector Switch, and PROGRAM of the Mode Selector Switch. Depress and

Hold the MENU switch for approximately 10 sec. The unit will display “C1 run” when it has entered the Calibration Mode

2. Press the MENU button to display the Decaf Coffee Flow Rate calibration menu “C3 run”

3. Reconnect the elbow to the Left (Decaf) Coffee Mixing Chamber outlet. Place a container under Dispense Tip and depress the SMALL cup button. A steady stream of water comes out the tip (20 seconds).

4. Allow the tip to stop dripping. Discard the water collected

5. Place a 1000 ml graduated container under Dispense Tip.

6. Press the DECAF dispense button. The dispenser will display a 20 second count down timer and then stop dispensing automatically.

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

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

The acceptable range for the volume of water collected is .39 - .43 liters

9. If the amount of water collected is not within the acceptable range, empty the graduated container and repeat

STEPS 5 – 8.

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

11. When satisfied with the volume of water collected, press the MENU switch. The current Water Calibration volume “C3 XX” will be displayed.

12. Use the (-) / (+) keys to adjust number displayed to the amount measured in STEP 8.

Regular Coffee - Dispenser Flow Rate Calibration

Depress the MENU button to display the Regular Coffee Flow Rate calibration menu “C4 run”.

Repeat STEPS 3 – 12 above for the right side Regular dispense valve, using the LARGE cup button.

Field Calibrating the Empty Product Warning

The dispenser will automatically illuminate the LED next to the Decaf or Hot Chocolate button when the Decaf or

Regular coffee BIB is empty. The Refill message is triggered when the conductance sensor reading drops below the minimum setting. The factory set minimum is 450 and should be correct for many locations. However, in some areas the harness of the local water supply will affect this reading. If the Refill message doesn’t come on when the container is empty, or the message comes on too early and there is still concentrate in the container, use the following procedure to find the correct Empty Product Threshold.

Calibrating The Empty Product Threshold

1. Remove the coffee concentrate BIB(s) from the Unit

2. Open the dispenser door to access the digital programming module with LED

3. Place a large container under the dispenser tip.

4. Place the NORMAL/PROGRAM/RINSE switch into the RINSE position

5. Press any dispense button on the door. The unit will automatically rinse for eight seconds. Repeat until the water exiting the coffee nozzle is running clear.

6. Place the NORMAL/PROGRAM/RINSE switch into the RUN position.

7. Press the LARGE and the BLACK COFFEE button. Observe the numbers display on the LED panel, the conductance reading will be displayed. (NOTE: It is typical for this number to fluctuate (+/-25) about the nominal value.) This is the conductance of the water in your area. Record this reading.

8. Repeat steps six and seven, only pressing LARGE, DECAF and BLACK COFFEE button. Record this reading.

22 39328.3 101513

9. Install the coffee BIB’s into the unit, and prime the pumps. Dispense several cups of both regular coffee and

Decaf coffee. If either one or both the DECAF and HOT CHOCOLATE LED illuminates during this process and dispensing is disabled, the EMPTY PRODUCT WARNING can be reset by priming the appropriate pump momentarily.

10. After several cups of both coffees have been dispensing, dispense both a REGULAR coffee and a DECAF coffee. Observe the conductivity reading for each, and record.

11. Take the average of the largest reading from steps seven and eight with the lowest reading from step ten, and enter this new value in the Empty BIB threshold position, “P10 XXX”, see Programming the dispenser.

Example, if the conductance readings with water from steps six and seven are 225 and 250, and the conductance readings with coffee from step ten is 355 and 370, you would average 250 and 355, and enter “302” for the empty BIB threshold in “P10 XXX”.

Field Adjustment of Powder Hoppers

The powder throw for the powder products is pre-set from the factory. It can be checked and adjusted in the field using this calibration procedure.

Adjusting the Hopper Throw Weight

1. Open the dispenser door to access the digital programming module with LED.

2. Remove the mixing chamber below the hopper outlet elbow.

3. Select PROGRAM on the Function Selector Switch, and NORMAL for the Mode Selector Switch.

4. Press the MENU button to display the Left Hopper Motor calibration menu “04 run”

5. Hold a container under the hopper outlet elbows, and press any beverage button on the front door.

6. The left hopper will run automatically for 10 second, and then stop.

7. Weight the contents of the container. Divide by 10 to determine grams or ounce per second of throw.

8. Press the MENU button to increment the display to menu “O4 XXX”. The number displayed is the power level drive of the hopper motor. The power level can be increased or decreased by pressing (-) or (+) button.

Each increment is equal to approximately a 1% increase or decrease in hopper motor speed.

9. Press the MENU button to display the Right Hopper Motor calibration menu “05 run”.

10. Repeat steps 5 – 8 to measure and adjust the right hopper throw weight.

11. Replace the powder-mixing chamber, and return the Function Selector Switch to the RUN position.
