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 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 3. plunger. 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 seals over the flange 2. at the rear of the cooling drums and press the seals firmly into place as shown. Align the auger shafts with the 3. augers. Push the augers as far as they will go and rotate them 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 hoppers 5. and install them over the augers and cooling drums. Slide them into place and push 6.
Auto-fill Cleaning Instructions (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. Fill bucket with 4 gallons of warm water (120-180 deg. F).
REQUIRED REGULAR MAINENANCE: Semi Annual: Bunn #34245.0000 is required to perform the semi annual Preventive maintenance: Note: Service caused by failure to perform required maintenance is not covered by warranty.

REQUIRED REGULAR MAINENANCE (Continued) 6. Pull the auger shaft assembly straight out of cooling drum. Inspect the shaft for abnormal wear. 7. From the front of dispenser, remove the seal and blue bushing from cooling drum and discard them. 8. Clean seal and bushing surfaces of the cooling drum very thoroughly. 9. Refer to FIG 1, and slip new blue bushing into cooling drum. 10. Place seal on insertion tool #28395.0000 as shown in FIG 2. Make sure open face of seal is toward cooling drum. 11.
