Follow this Technical Manual to convert the old ice bank control, part #S0513-A to the new style ice bank control, part #S0068-U. The old style ice bank control came standard in all Crysalli models made in 2019 and prior. Beginning in 2020, the new style ice bank control, part #S0068-U comes standard when you purchase a new water chiller. If you run across an old style control, follow these steps to successfully convert to the new standard ice bank control. Go to the bottom to download a "printer friendly" version to use

Removal of original mechanical Ice Bank Control (IBC)

  1. Shut off water, power and CO2 to the Crysalli system
  2. Remove lid from chiller
  3. Remove white pipe stem to drain the water bath
  4. Allow the ice bank to defrost completely
    1. Defrosting the ice bank can take ~24 hours. Shut the power off the day before service
    2. Warm water can be poured over ice bank to speed up the melting process or you can use a hairdryer to melt the ice bank.
    3. Do not use screwdriver, pick or sharp object to break ice bank
  5. Remove the screws and move the front/bulkhead panel to access electrical board. Remove the cover plate for the electrical box.
  6. Next, remove the side panel to access existing ice bank control
    1. For the CR-2 & CR-UCM2 series units you will access the electrical board through the rear panel or panel on the opposite side of the bulkhead panel.
  7. Using needle nose pliers, remove terminal plugs from IBC1 (Fig 1.1 item a) & IBC2 (Fig 1.1 item b)(sparkling water systems)
    1. For “still water only chillers” remove terminal plugs from A6 (Fig 1.2 item a) and D5 (Fig 1.2 item b)

 Figure 11Figure 12

  1. Remove the ice bank control from mounting bracket
  2. When the ice is completely melted from the evaporator, remove the ice bank bulb and bracket (Fig 1.3)
  3. Now you can completely remove the ice bank control assembly from the Crysalli system

Installation of new electronic Ice Bank Control (IBC)

  1. The electronic ice bank control is programmed by Crysalli to the settings designed for the Crysalli water chiller systems
    1. Do not substitute for other IBC models
  2. Attach the WHITE thermal control sensor & bracket to the evaporator coil in the water bath
    1. Each Crysalli model has a specific location for mounting the sensor bracket to the evaporator to maintain a uniform ice block formation
    2. See pictures (Fig 3.1-3.5) of the different models and locations and cross reference it to the model you are working on
    3. After identifying the correct location secure the sensor bracket to the evaporator coil using the supplied zip tie
  3. Use the zip ties provided to secure the white thermal control sensor wire to the water coil (Fig 3.1-3.5)
  4. Do not leave slack in the control sensor wire and make sure the wire is secured to water coil away from wher the ice bank will form
    1. *NOTE: If the thermal control sensor wire freezes within the ice bank it will send false readings back to the electronic controller cycling the compressor off prematurely
  5. Route the thermal control sensor wire back to the electronic controller and plug the terminal connector into the thermal control box
  6. Attach the electronic IBC control box to the same mounting bracket where the original ice bank control was located
  7. Zip tie any slack wire keeping it clean and away from any moving parts within the condensing system
  8. Route the brown, black and white wires from the IBC control box to the Crysalli circuit board

Sparkling water system wiring

  1. Connect the BLACK wire to terminal IBC1 (Fig 2.1 item a)
  2. Connect the BROWN wire to terminal IBC2 (Fig 2.1 item b)
  3. Connect the WHITE wire to terminal W4 (Fig 2.1 item c)

Figure 21

Still water system wiring

  1. Connect the BLACK wire to terminal A6 (Fig 2.2 item a)
  2. Connect the BROWN wire to terminal D5 (Fig 2.2 item c)
  3. Connect the WHITE wire to terminal B5 (Fig 2.2 item b)

Figure 22

*NOTE: If the unit has a different circuit board than what is shown, call the Crysalli service manager for wiring details

Start up system

  1. Reinstall the white pipe stem
  2. Reinstall and secure all panels that were removed
  3. Fill the water bath to 1/4” below the top of the white pipe stem
  4. Turn on the water, power and CO2
  5. Listen for the compressor to kick on
  6. Install lid
  7. Allow for 3-4 hours for the ice bank to form
