Bunn ULTRA-2 service manual Other Recommendations for Your Dispenser, Preventive Maintenance

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 The Dispenser on page 10 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.
