INTRODUCTION Safety first! To avoid electrical shock, unplug dispenser from power source before servicing inside. WARNING: When powered, the condenser cooling fan will turn on every 30 minutes to aid cooling the entire unit, even when not in the ICE or CHILL modes. KEEP HANDS AWAY FROM FAN! Basic Maintenance In order to maintain proper machine operation, the shaft seals and bushings need to be replaced as a Preventative Maintenance measure. A reminder message will appear every 6 months.
TEMP & TORQUE SCREEN Press and hold for five seconds the ULTRA and ICE hidden switches to display the TEMP & TORQUE. The temperature of each cooling drum and the hot gas temperature will toggle back and forth. The auger torque is displayed continuously. Press and release the ULTRA and ICE hidden switches to return to HOME SCREEN. The TEMP & TORQUE mode is typically used for service.
OPERATING CONTROLS ULTRA-1 There are three of these switches that will be used for the operation of the dispenser. 1 2 3 P3932 1. switch (upper left corner of the control pad) This switch is the ON/OFF toggle switch which powers up the dispenser and the LCD display. When ON the Date and Time toggle back and forth continously except during programming. 2. (upper right corner) This is used to turn the auger motor to AUGER ON, AUGER OFF or AUGER REFILL ON. (Refill only applicable when installed) 3.
OPERATING CONTROLS ULTRA-2 There are five of these switches that will be used for the operation of the dispenser. 1 P3677 2 3 4 5 1. switch (upper left corner of the control pad) This switch is the ON/OFF toggle switch which powers up the dispenser and the LCD display.

RECOMMENDED DAILY CLEANING (Continued) 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).
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. (Quick Connect/Disconnect) fitting on the concentrate suction line open. A connector from an empty bag will work. Sanitizing Procedure 1.
PREVENTIVE MAINTENANCE A common problem occurs when the proper preventive maintenance procedures are not followed. Failure to perform these procedures may result in damaged equipment and may not be covered by warranty. Please check the following items before assuming a refrigeration fault. When the product does not freeze, there are several possibilities other than a failure in the refrigeration system.
