Frequently Asked Questions - ULTRA-2A R452 Bunn

How do I install my Bunn ULTRA-2A R452 water dispenser?

Installation requires a 1/4-inch water line and a standard electrical outlet. The unit can be placed on a countertop or mounted to the wall using the supplied bracket. For detailed steps, refer to the installation manual included with the product.

What are the temperature settings for hot and cold water?

The hot water is typically maintained at 200°F (93°C) and the cold water at 50°F (10°C). These temperatures are factory set and not adjustable by the user.

How often should I descale the dispenser?

Descaling is recommended every 6 months using a commercial descaling solution or a mixture of white vinegar and water. This prevents mineral buildup and ensures optimal performance.

Can I use a water filter with this dispenser?

Yes, the ULTRA-2A R452 is designed to work with an optional inline water filter (not included). Installing a filter improves water taste and reduces scale. Replace the filter annually or as per local water conditions.

What should I do if the water flow is slow?

Slow flow may indicate a clogged inlet screen or air in the line. Check the water supply valve and ensure it is fully open. If using a filter, try replacing it. Also, clean the internal reservoirs with a descaling solution.

How do I clean the exterior of the dispenser?

Wipe the stainless steel exterior with a soft cloth dampened with mild soap and water. Avoid abrasive cleaners. For the stainless steel finish, use a stainless steel cleaner to maintain shine.

Is the dispenser safe for use in a commercial setting?

Yes, this model is UL listed and meets NSF/ANSI 372 for lead-free materials. It is suitable for both commercial and residential use, provided it is installed correctly by a qualified technician.

Why is my hot water not getting hot?

Check the power supply and ensure the unit is plugged in. If the circuit breaker tripped, reset it. The heater may need to be reset by pressing the over-temperature reset button located on the back of the unit.

Can I dispense room temperature water?

The ULTRA-2A R452 provides only hot and cold water. If you need room temperature water, allow the water to sit at room temperature after dispensing cold water, or use a separate faucet.

Where can I purchase replacement parts?

Replacement parts are available through Bunn authorized dealers and online retailers. Common parts include reservoirs, heating elements, and faucets. Contact Bunn customer service for assistance.

NOTE: Several other menu functions are included in this dispenser. Please refer the PROGRAMMING MANUAL available on the BUNN website at www.bunn.com.

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. Using products with a brix lower than 12 may cause physical damage to the equipment drive system.

- 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. If the auger is exposed, air will become entrapped in the mixture resulting in a clouded foamy consistency. This condition could also cause physical damage to the equipment drive system.

- You may find it beneficial to turn down the ice controls to keep the ice granules from growing too large. Refer to Programming on page 12 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.

- Any signage attached to the equipment must not be made with PVC, also known as Vinyl or Polyvinyl Chloride.

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

2. 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.

3. 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.

4. 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.

AUTO-FILL SANITIZING INSTRUCTIONS

(WITH INTERNAL BRIXING SYSTEM INSTALLED)

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.

1. Select "auger on" and set the cooling mode to "off" for each hopper being sanitized.

2. Empty product from each hopper being sanitized.

3. Pour one gallon of warm water into each hopper to rinse the remaining product, and then drain hopper(s).

4. 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.

5. 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.

1. Once full, allow sanitizer to sit in the hopper(s) for 10 minutes.

2. Select "auger off" for each hopper being sanitized. Drain the sanitizer from the hopper(s).

3. Remove the B-I-B connector(s) from the sanitizer bucket and reconnect to the product B-I-B(s).
