    FREIGHT DAMAGE CLAIMS PROCEDURE The deliverer of your equipment (freight company, distributor or dealer) is responsible for loss or damage of your shipment. All claims must be filed with the deliverer of your equipment. Please follow the steps below to deter- mine if your shipment is satisfactory or if a claim must be filed: 1.

  • Page 15: Installation Instructions

    INSTALLATION INSTRUCTIONS Installation and start-up of the equipment should be performed by the distributor or the dealer’s professional staff. LOCATION OF EQUIPMENT For maximum performance the location should be away from heat sources such as ovens, direct sunlight, hot air discharge, etc. To reduce cost of maintenance and loss of efficiency, avoid placing air-cooled equipment in areas where grease, flour and other airborne contaminants are present.

    Bin Drain Tube AIR-COOLED MODELS PLUMBING CONNECTIONS 1. All plumbing lines and connections must conform to local and national plumbing codes. 2. Line shut-off valves must be located in supply water lines for cuber and condenser if product is water- cooled.

  • Page 18: Start-Up And Check Out

    3/8I WATER PAN RIGHT SIDE VIEW 4. If water-cooled, are inlet and drain connections to condenser correct to prevent “water hammer”? 5. Are drain lines separate and vented? 6. Is there 6I clearance on all sides and top for proper air circulation? 7.

  • Page 19: Owner -Operator

    The installation is not complete until you are sure the owner-operator understands the cuber operation and his or her responsibility of preventative maintenance. Does the owner-operator know: 1. Location of electrical disconnect switch and water shut-off valves? 2. How to start and/or shut down the product, clean and sanitize it? 3.

  • Page 20: Sanitizing Procedures

    SANITIZING PROCEDURES NOTE: To be performed only after cleaning the ice machine: 1. Add 1/4 ounce (7.08 g) sodium hypochlorite solution (common liquid laundry bleach) to the water pan and allow the pump to circulate the solution for 5 minutes. You may also use a commercial sanitizer such as Calgon Ice Machine Sanitizer following the directions on the product label.
  • Page 21 4. You have the option of selecting dump cycle intervals of: S every cycle; (Standard setting from factory) S every 3rd cycle; S every 5th cycle; S every 7th cycle. Remember, the higher the mineral content in the water supply the more often it will be required to dump the wa- ter and/or clean the product if proper water treatment is not used.

    Always wait for the second cycle before making any adjustments. TOTAL ICE CAPACITY Ice capacity of any ice maker is affected by many operating conditions, such as water and air temperature and location factors. Please review the capacity tables in this manual for average 24-hour capacity under various conditions.

    LED INDICATORS The LEDs are board circuit indicators. If the LED in the functional board circuit is complete, check component.

  • Page 25: Circuit Board Diagnostic Procedure

    CIRCUIT BOARD DIAGNOSTIC PROCEDURE Turn the power switch to the “ON” position. The D-5 red LED (error indicator) will be illuminated for 2 seconds. After the D-5 red LED goes out, short across the bottom two terminals of the Test Plug with a jumper wire or a pocket screwdriver and then remove the jumper.

  • Page 26: Restoring Ice Thickness Potentiometer To Factory Setting

    RESTORING ICE THICKNESS POTENTIOMETER TO FACTORY SETTING 1. Turn cuber power switch to the OFF (center) position. 2. Unplug the proximity switch(es) and the thermistor(s) from the circuit board. 3. Turn the cuber power switch to the ON position. The red LED D-5 will illuminate for 2 seconds and then go out.

  • Page 27: Component Function (Circuit Board Etc.)

    COMPONENT FUNCTION (CIRCUIT BOARD ETC.) TEST PLUG Board manufactures check point. DO NOT ATTEMPT ANY VOLTAGE CHECKS AT THESE PINS. SENSORS Condenser sensor (WHITE) and suction line sensor (BROWN) are thermistors rated 1k ohm at room tempera- ture. S Condenser sensor signals the circuit board for fan cycling and also serves as the high temperature safety shut down.

  • Page 28: Voltage Selector Switch

    VOLTAGE SELECTOR SWITCH 1. Selector bar in center position, switch is open. Product is inoperative. 2. Selector bar in down position, selection is for 115 VAC. 3. Selector bar in up position, selection is for 230 VAC. STACKING CABLE When stacking the “I” series cuber the connecting cable (connecting the two (2) circuit boards) will allow: the bottom Unit to shut off on the full bin signal (or any error code), the top Unit will then finish the cycle it is in and shut down.

  • Page 29: Starving Txv - Product Symptoms

    6. Ventilation problems The expansion valves used on Cornelius “I” series ice equipment have special super heat settings and bulb charge designed for the product load and HP 62 refrigerant. Should the need arise to replace this or any refrig- erant components, be certain to use only components recommended by Cornelius for the model of the Cuber being serviced.

  • Page 30: Service Stem Valves

    SERVICE STEM VALVES When closing the service stem valves to remove your gauge and manifold set always close the high side stem valve first. Following this procedure will allow the system to “PULL” the refrigerant vapor from your manifold set to reduce refrigerant loss.

  • Page 31: Compressor & Starting Component Check-Out Procedure

    Check for supply voltage from circuit board, lead connections to contactor coil, and ohms value of coil. * (3) if the product is 3 phase Note: See compressor run-on condition check procedure on page 31. COMPRESSOR & STARTING COMPONENT CHECK-OUT PROCEDURE When compressors fail to start or run properly, it is normally the external electrical supply or the compressor start components that are defective –...

  • Page 32: Leak Detection

    2. To check the compressor motor for accidental ground, perform a continuity check between terminals C, R and S to the compressor shell or a copper line of the refrigeration system (do not use a painted surface). Continuity present, the compressor windings are grounded and the compressor must be replaced. If the compressor starts, but trips repeatedly on the overload protector, remember that the overload is both tem- perature and current activated.
  • Page 33 A good vacuum is not always easy to measure, however the goal is to have less then 1% non-condensible va- pors in the system at the completion of the evacuation. Basic guidelines with a good pump would be to evacu- ate a selfcontained product 30 to 45 minutes and a remote product no less than 60 minutes.

  • Page 34: High Pressure Safety Switch

    Chemical analysis is the key requirement to the definition of “Reclaim”. Regardless of the purity levels reached by a re-processing method, the refrigerant is not “reclaimed” unless it has been chemically analyzed and meets ARI Standard. HIGH PRESSURE SAFETY SWITCH All water-cooled and remote products contain a high pressure safety cut-out switch.

    INSTALLATION INSTRUCTIONS REMOTE CONDENSERS 1. Follow the standard installation instructions supplied with cuber. Do not hook cuber into the power source until the remote condenser and line set installation is complete. 2. Assembly of remote condenser (see drawing): Assemble legs to base panel. Install leg supports on legs. Locate the remote condenser in a well–ventilated area on the roof away from other refrigeration equip- ment’s condenser discharge air flow.
  • Page 75 The condenser fan may cycle off during the harvest cycle – this would be normal. NOTE: Installing an IMI Cornelius remote cuber with other than an IMI Cornelius remote condenser and line set may be reason to void the cuber warranty.

  • Page 76: Remote Condenser Location

    To prevent the combination of rises, drops and horizontal runs exceeding the compressor start-up and pumping design limit, the following calculations should be made: NOTE: Max. line–set for IMI Cornelius cubers is 55 ft. Do not confuse line length with calculated line distance A - (RISE) CONDENSER HIGHER THAN EVAP.
  • Page 77 Insert measured horizontal distance into formula. No calculation is necessary. (6 ft.) [1.828 me- ters]. Add the calculated rise, calculated drop, and horizontal distance together to get the total calcu- lated distance (25.5 + 52.8 + 6) equals 84.3 ft. [25.694 meters]. If 100 ft. [30.48 meters] total cal- culated distance is exceeded, the condenser must be moved to a new location which permits proper equipment operation.
  • Page 78 Check all fittings for leaks. 5. Final Installation: Remove grill from the right-hand side panel of cuber. Turn service port on receiver tank to open position releasing refrigerant to the balance of the system. Leak check line-set connections at cuber and condenser. Replace grill.
