For the first case switch off and dry the base of the unit. For the second case turn unit on/off through main switch inside cabinet.
  • Page 25: Structure

    Structure Accessibility BEFORE OPENING THE APPLIANCE, ALWAYS DISCONNECT IT FROM THE POWER SUPPLY. ALSO SWITCH OFF THE MAIN WATER VALVE AT HOME TO AVOID FLOODING. To access the internal parts of the appliance, proceed as described on instructions manual: − Take the drip tray lifting the front side first.
  • Page 26: Access To Components Compartment

    Accessibility to components compartment To access to the component compartment, placed on the rear side of the machine, we need to remove the rear sheet metal panel. Remove 6 screws to take off the rear panel. Three from one side, three from the other side.
  • Page 27 Removal of the rear panel gives access to components: compressor, gas and water valves, motors, main board, pump, etc… 1. Filter and filter head 2. Water pressure reducer 3. CO2 cylinder 4. On/Off water valve 5. Compressor 6. Condenser 7. Water and gas valves 8.
  • Page 28 To remove the main board please do the following steps: Remove the cable that connects the main board case control panel. Afterwards unplug also the connectors from the bottom side. Remove the screw that fixes the main board case to its support At this point, it’s possible to remove also the main board support that is attached to the water tank by two screws.
  • Page 29 To remove water inlet valve, do the following: BE SURE THE WATER MAIN VALVE IS CLOSED, IN ORDER TO AVOID FLOODING Unplug the inlet water tube from the connector. Unplug also the signal and power cables from the water inlet valve pulling gently the connectors.
  • Page 30 To remove the drainage kit, do the following (be sure that the water tank is empty): Remove the drainage tube by turning the connector bolt anticlockwise. Remove the black external plastic bolt in order to unplug the plastic drainage connector from the support. Next step is to disconnect the drainage tube from the water tank.
  • Page 31 The thermostat needs no calibration. In case there's a need to change the thermostat, just unplug the two probe connectors and remove the two screws on the top side of the thermostat support. To change or remove the pump, just remove the 4 screws that tighten the pump to the rear side of the water tank.
  • Page 32 Opposite we find a photo from the first assembly steps, where we could see the adapter support, that supports also an electric water valve. To change this valve, remove two screws on the top side of the support. It's possible to change the pressure switch. Be sure the CO2 bottle valve is closed.
  • Page 33 To replace the water dispense valve, do as follows: Remove all cables pulling firmly the connectors. Then, pull the plastic water tubes from the valve making attention to not flood the appliance (there could be some water inside the water tubes). Pull the valve out from its support.
  • Page 34: Access To The Water Tank Compartment

    Accessibility to water tank compartment To access to the water tank, just remove all six screws from the top of the water tank. We can see the inside the water tank the ice bin evaporator and the water evaporator. There’s also the pump, the ice tray and the auger that pushes the ice into the ice nozzle.
  • Page 35 Remove also the screw on the side panel of the plastic cover. At this point it’s possible to take off the plastic cover. The carbonator could be removed just pulling it upwards. First unplug all signal cables. Opposite, we can see the water level probes (1), the auger and auger support(2), and the thermostat probe(3).
  • Page 36: Access To Command Panel And Light Bar

    Accessibility to command panel and light bar To remove the command panel, first unplug the main board cable. Then, we must free the command panel from its supports. To do it, just remove the screws (2 + 2) from the command panel supports.
