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.
RECOMMENDED DAILY CLEANING (ULTRA-2 shown) NOTE – Turn the power OFF to the dispenser before proceeding. 1. Empty all product from the hopper(s). Disconnect the hopper lid lamp cord(s) and remove the lids. 2. Depress the hopper lock plung- 3. er. Lift the hopper up slightly. Pull forward to remove. 4. Pull the auger from the cooling drum. 5. Remove the cooling drum seal 6. from the rear of the drum. Caution: The faucet valve is 7. under spring tension.
INSTALLATION 1. Install the seal(s) over the 2. flange at the rear of the cooling drum(s) and press the seal(s) firmly into place as shown. Align the auger shaft(s) with the 3. auger(s). Push the auger(s) as far as they will go and rotate so the flat face of the auger shaft is aligned with the flat face of the auger nose. Install auger nose bushing into inside front of hopper. 4. Thoroughly rinse the hopper(s) 5. and install over the auger(s) and cooling drum(s). Slide into place and push down 6.
AUTO-FILL SET UP INSTRUCTIONS (ULTRA-2 Models only) 1. Remove right side panel. 4. Install snap clamps on hoses, just above the bushings to prevent hoses from being pulled loose from the solenoid valves. 2. Remove hole plugs in bottom of machine to route hoses to valves. 3. Connect and properly clamp supply product and water lines from Brix pumps. Ensure that all connections are made to the correct valve for the right or left hopper. All valves are labeled to help with this process. 5.
AUTO-FILL SET UP INSTRUCTIONS (cont.) 8. Apply power to machine and turn water on for Brix Pump operation. Refer to the Programming section of this manual in the Refill Threshold section to check refill for proper operation. 9. At the threshold screen, with no product in the hopper, confirm the number on the left (top) of the screen is around 250. The number on the right of the screen is factory set to 155. The factory set point should not need any adjustment. 10.
Auto-fill Cleaning Instructions (ULTRA-2 Models only) (With Brixing Pump Installed) 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. fitting on the concentrate suction line open. A connector from an empty bag will work. Sanitizing Procedure 1.
