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.)

NOTE – Bunn-O-Matic does not recommend the use of any extension cord with these dispensers.

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 (ON/OFF) switch to start the Auger Motor.

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 (ON/OFF) switch to start the Auger Motor.

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

the selected hopper.

4.Wait for the liquid to cool.

18	32080 021202

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.

19	32080 021202

RECOMMENDED DAILY CLEANING

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

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.
