Autofill Cleaning Instructions - Bunn ULTRA-1 Installation & Operating Manual

Materials required
1. Non-sudsing liquid detergent (such as common household automatic dishwasher liquid detergent).
2. Household bleach (Sodium chloride solution: 5.25%) or equivalent.
3. Clean five (5) gallon bucket.
4. Measuring Cup.
5. An adaptor is needed to hold the Q.C.D. (Quick Connect/Disconnect) fitting on the concentrate suction line open. A
connector from an empty bag will work.
Sanitizing Procedure
1. Fill bucket with 4 gallons of warm water (120-180 deg. F).
2. Measure 4 ounces (1/2 cup) of the liquid detergent and add to the water.
3. Measure 2 ounces (1/4 cup) of bleach and add to the water, then stir, mixing evenly.
4. Ensure that the refill for the Ultra hopper is turned off.
5. Empty all product from the Ultra hopper.
6. Disconnect the concentrate line from the B-I-B and install adaptor on the quick disconnect so the line is open to the
sanitizing solution. Place concentrate inlet line into the bucket so that the Q.C.D. will stay at the bottom.
7. Press the auger button to turn on the "Auger Refill On" feature.
8. Allow system to run until the hopper is about 1/4 full then turn off refill.
9. Switch three way sanitize valve to the Sanitize postion.
10. Turn refill system back on and let run until the hopper is almost full then turn off refill.
11. Allow sanitizer to sit in system for 10 minutes.
12. Drain sanitizer from hopper and remove the Q.C.D. from the sanitizer bucket.
13. Empty remaining sanitizer and refill bucket with about 2 gallons of warm (120-180 deg. F) rinse water.
14. Turn sanitize valve back to dispense position.
15. Place Q.C.D. into rinse water and turn on refill system.
16. Run until hopper is about 1/4 full.
17. Turn off refill system and drain hoppers.
18. Refer to the Recommended Cleaning instructions and follow these steps to clean the hopper, lid and other dispense
parts.
1. Fill bucket with 4 gallons of 120 Degree F water and sanitizing solution to equal 100 ppm of available chlorine.
Note: some installations may require more sanitizer solution to fill the supply lines completely.
2. Select "auger on" and set the cooling mode to "off" for each hopper being sanitized.
3. Empty product from each hopper being sanitized.
4. Pour one gallon of warm water into each hopper to rinse the remaining product, and then drain hopper(s).
5. Disconnect concentrate line from the B-I-B and set so the sanitizer can flow freely through it. Place the connector in
the bottom of the sanitizer solution bucket.
6. Select "auger refill on" for each hopper being sanitized. Allow hoppers to fill until system reaches the fill probe. If a
refill fault occurs, press the Ultra button to clear and continue filling. Repeat this process until the product line runs
clear.
Note: You may need to drain the hopper again and allow filling until the product line runs clear, indicating sanitizer has
completely filled the lines. If the delay refill system is activated, you may also need to turn the auger off, then back to
"auger refill on" to fill the hopper without the delay.
7. Once full, allow sanitizer to sit in the hopper(s) for 10 minutes.
8. Select "auger off" for each hopper being sanitized. Drain the sanitizer from the hopper(s).
9. Remove the B-I-B connector(s) from the sanitizer bucket and reconnect to the product B-I-B(s).
10. Refer to the Recommended Cleaning instructions of this manual and follow the steps to remove, clean and sanitize the
hopper(s), lid(s) and other dispense parts.
11. Select "auger refill on" for each hopper being sanitized and allow to run until product starts flowing into the hopper(s).
12. Select "auger off" for each hopper being sanitized, then drain hopper(s).
13. The dispenser is now ready to be turned on and filled for use.
