2 2 120 volt / 15 amp dedicated outlet (no extension cord) At least 6” clearance for airflow (back and sides). Recommended for indoor use. If it must be used outdoors, it will take longer to freeze. (Keep out of direct sunlight) Site Requirements

Machine should be level or slightly lower in front Remove shipping eye-bolts from compressor Install rear gaskets on drums (no grease on ULTRA) Install augers (no grease on ULTRA) Install hoppers (no grease on ULTRA) Fill with product & install hopper lids Unit can now be powered up

Confidential material. 4 Cooling Drum Alignment The "A" shaped Cooling Drum Shipping Supports, removed during Initial Setup, should be kept and used as a tool to reset the alignment of the cooling drums should it ever be required. Symptoms: Squeaky Operation, hopper lifts or won't seat properly, hopper is pushed to one side or the other. To check alignment 1. Place the "A" shaped support on the auger shaft with the ledge under the cooling drum. 2. Lift the cooling drum while rotating the support into a vertical position. The boss on the very bottom will drop into the hopper drip tray's drain hole. When in its proper position, the cooling drum will cause a slight pressure on the hopper drip tray drain hole and the two legs will be equidistant from the hopper drip tray. If adjustment is needed, remove the support and gently force the free end of the evaporator in the direction the adjustment is needed. Reinstall the support, check the alignment, and readjust the cooling drums as required.

17 © 2001 Bunn-O-Matic Corporation. All rights reserved. Confidential material. 17 Cooling Drum/Auger Brix level should be at least 9-12, if it’s less, the ice could be too solid to shave off, and possibly break the auger. Too high, and it may not freeze! Auger shaves ice off as it forms on drum

This breaks up chunks of ice that may be floating on top. Torque sensing is ignored during reverse mode. (ULTRA software will start a reverse sequence if the solenoids stay open for an extended time. Auger Drive Control

22 © 2001 Bunn-O-Matic Corporation. All rights reserved. Confidential material. 22 Auger Drive/PM Ceramic coating Keep grease & dirt off pins, or it could prevent freezing! PM every 6 months

23 © 2001 Bunn-O-Matic Corporation. All rights reserved. Confidential material. 23 Auger Drive/PM Front of drum Failure to PM this area could lead to loss of freezing, due to product (sugar) build up on the bushings & seals over-loading the torque sensing systems Seal Bushing

25 © 2001 Bunn-O-Matic Corporation. All rights reserved. Confidential material. 25 Auger Drive/Torque Sensing As the ice thickens, the torsion springs allow a slight twisting motion, allowing the two pins to move farther apart. If user has to keep setting thickness to a higher level, it may be an indication of worn or broken springs Torsion springs transmit driving force from motor drive coupler to shaft drive coupler

26 © 2001 Bunn-O-Matic Corporation. All rights reserved. Confidential material. 26 The torque sensor is a 5vdc board consisting of an infra-red LED & photo-transistor. Output is 5v when blocked by pins or 0v unblocked. To test, turn off Augers, connect meter across pins 1 & 3, using a strip of paper, block & unblock the light beam between the two sensors. Watch the meter for HIGH-low switching. Switching line + 5vdc - Common Phototransistor LED If there’s no reading, check for 5v supply, at pins 2-3 Torque Sensing Direction of light beam

27 © 2001 Bunn-O-Matic Corporation. All rights reserved. Confidential material. 27 Invisible Infra red beam is momentarily blocked by the Motor pin, then the Shaft pin. Torque Sensing As the Auger drive shaft rotates, the two pins block the beam of light. The micro- processor calculates the distance between the pins and determines the refrigerant solenoid shut off point, based on where the thickness adjustment is set.
