SITE PREPARATION

The dispenser is very heavy. Place it on a sturdy counter or shelf capable of supporting at least 180 lbs. It is for indoor use only.

The dispenser must have at least six inches of space behind it. This space is needed for airflow, air filter removal, and cleaning. A clearance of at approximately six inches is recommended between the dispenser sides and the wall or another appliance. The dispenser performs better if not placed near any heating appliance. Leave some space so the dispenser can be moved for cleaning.

ELECTRICAL REQUIREMENTS

CAUTION – Improper electrical installation will damage components. An electrician must provide electrical service as specified below.

Model ULTRA-2, This dispenser has an attached cordset and requires a 2-wire, grounded, individual branch circuit rated 120 volts ac, 15 amp, single phase, 60 Hz. The mating connector must be a NEMA 5-15R.

(Refer to the dataplate for exact electrical requirements.)

Model ULTRA-2A, This dispenser has an attached cordset and requires a 2-wire, grounded, individual branch circuit rated 230 volts ac, 10 amp, single phase, 50 Hz. (Refer to the dataplate for exact electrical requirements.)

USING THE DISPENSER FOR GRANITA-TYPE PRODUCTS

1.

Lift the lid slightly for the selected hopper and slide back to gain access to the hopper.

2.

Place the pre-mixed liquid product in the selected hopper.

3.

a. Press and release the (ON/OFF) switch to power on the dispenser.

b. Press and release the Left and/or Right

AutoFill when applicable.

(ON/OFF) switch to start the Auger Motor and to turn on c. Press and release the (OFF/ICE/CHILL) switch and select ICE to begin the cooling process for the selected hopper.

4.

Wait for the liquid to freeze to the desired consistency.

HINTS – Bunn-O-Matic recommends that the product in the dispenser be thawed each day, usually overnight.

The ice granules get too large and a consistent product is difficult to maintain if left frozen for an extended period of time. Set the NIGHT mode for a few hours each night and return it to the DAY mode when the product has thawed sufficiently. You’ll know it is in the NIGHT mode because the display will indicate NIGHT

MODE.

USING THE DISPENSER FOR COLD LIQUID PRODUCTS

1.

Lift the lid slightly for the selected hopper and slide back to gain access to the hopper.

2.

Place the pre-mixed liquid product in the selected hopper.

3.

a. Press and release the (ON/OFF) switch to power on the dispenser.

b. Press and release the Left and/or Right

AutoFill when applicable.

(ON/OFF) switch to start the Auger Motor and to turn on

(OFF/ICE/CHILL) switch and select CHILL to begin the cooling process for c. Press and release the the selected hopper.

Wait for the liquid to cool.

24 32080.0001 021105

OTHER RECOMMENDATIONS FOR YOUR DISPENSER

• Whether liquid concentrate or granulated powder, all product must be thoroughly mixed BEFORE adding it to the hoppers.

• For best results with granita-type products, use only products with an apparent brix of 12 or higher. Some products may work with an apparent brix as low as 9. Your experimentation with other products will be the best guide in this area.

• Keep the pre-mixed liquid product refrigerated. This reduces cooling/freezing time in the dispenser.

• Keep the hoppers topped-off during peak serving periods. Add pre-mixed liquid product as it is dispensed.

This reduces the cooling/freezing time and assures you of always having product ready to dispense.

• Keep the product level in the hoppers higher than the auger. Air will become entrapped in the mixture resulting in a clouded foamy consistency.

• You may find it beneficial to turn down the ice controls to keep the ice granules from growing too large.

Refer to Programming The Dispenser on page 11 for Setting the Consistency.

• Some products freeze at a lower temperature than others. You may notice frost or ice on the hoppers. This is normal and should not be a concern.

• Humidity in the air may cause sweating on the outside surfaces of the hoppers. This is to be expected and should not be a concern. The drip trays beneath the hoppers will capture this and cause it to flow to the lower drip tray for disposal.

• Some noises are to be expected during normal operation of the dispenser. By becoming familiar with the noises made during normal operation, you will be better able to listen for problems.

25 32080.0001 021105

RECOMMENDED DAILY CLEANING

NOTE – Turn the power OFF to the dispenser before proceeding.

1.

Empty all product from the hoppers. Disconnect the hopper lid lamp cords and remove the lids.

2.

Depress the hopper lock plunger. Lift the hopper up slightly.

3.

Pull forward to remove.

4.

Pull the auger from the cooling drum.

5.

Remove the cooling drum seal from the rear of the drum.

6.

Caution: The faucet valve is under spring tension. Spread one side of the handle first, then the other and disconnect from the hopper.

7.

Carefully slide the faucet valve up to remove the spring and faucet seal. Extra care should be taken when handling the seal to prevent damage. Do not fold the seal as this will cause damage to the Teflon ® sealing surface.

8.

Remove the auger nose bushing from inside the hopper.

9.

Care must be taken to ensure this surface does not get scratched during cleaning. Deep scratches could cause leakage around the seal.

10. Place all parts in a clean sink with mild hot water (120°F) and sanitizer solution. Allow all parts to soak for at least

5 minutes. Carefully wash all components with a clean wash cloth in the hot water and sanitizer solution. Use a clean, soft bristle brush as needed for the smaller components and tight areas. Do not immerse hopper lids. Use a commercial sanitizer that has 100 ppm of available chlorine with a concentration level of at least 3% available chlorine (KAY-5 Sanitizer). Follow the sanitizer’s mixing instructions to ensure 100 ppm of available chlorine.

11. Wash the drums, hopper drip trays, top covers, and outer enclosure using a clean wash cloth that has been dampened in the hot water and sanitizer solution. Pay particular attention to the shaft area and make sure it is thoroughly cleaned and sanitized.

12. Thoroughly rinse all surfaces with a clean wash cloth that has been dampened with hot water. Wipe dry with a clean dry wash cloth before reassembling the dispenser.

NOTE – Although most parts are dishwasher safe, they may be affected by the chemicals in some commercial sanitizing agents. Do not place the hopper nor hopper lids in a dishwasher. Rinse thoroughly before assembly.

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.
