    6. ACCESS TO INTERNAL COMPONENTS: To inspect the chiller from the top: 1. Disconnect the machine from the electrical supply. 2. Disconnect all water and CO2 connectors. 3. Purge the CO2 from the machine. 4. Allow to cool sufficiently. 5. Remove the outer lid. To remove outer lid, undo 3 Phillips Screws. 6.
  • Page 21 To access to internal components. 1. Disconnect the machine from the electrical supply. 2. Allow to cool sufficiently. 3. Remove the outer lid. To remove outer lid, undo 3 Phillips Screws. 4. Remove surround, To remove surround, undo 2 Phillips Screws on front and 4 on back. Place the panels to the side of the machine.
  • Page 22 Inlet Pressure Regulator Sporadically, dust or iron particles from the outer tubes during the first installation and during maintenance operations to external filters can clog the regulator. To replace the pressure regulator, disconnect inlet and outlet tubes and undo the 2 screws (a,b) located on the backside of the chiller.
  • Page 23 Carbonation Pump To replace the carbonation pump, disconnect the black wirings from the carbonation control module, loosen the 2 screws (c,d) located on the right side of the pump auxiliary bracket and remove the 2 screws on the left side (a,b); the pump can now be removed for maintenance.
  • Page 24 Carbonation Pump Electronic Control Unit To replace the carbonation pump ECU, disconnect the wirings from the ECU, and undo the screw (a) located on the top side of the bracket; the ECU can be removed for maintenance. During removal, be careful not to damage the electric wiring or the refrigeration group pipes.
  • Page 25 Dispense Solenoid Access: To access the dispense solenoid(s), the solenoid bracket need to be removed. Unscrew the four Phillips screws holding the bracket. If the dispense solenoid(s) need to be replaced unscrew the two Phillips screws holding the solenoid in place and remove tubing from solenoid body. During removal, be careful not to damage the electric wirings, refrigeration group pipes and water circuit pipes.
  • Page 26 Electronic PCB access Remove the lid of the chiller. Remove the PCB enclose lid by undoing two screws (a,b) this will give access to the PCB. Carefully remove the electrical connectors, do not apply too much force to avoid damage. Remove the PCB by undoing the 4 screws (c) located on the PCB itself.
  • Page 27 Compressor PCB, PRV valve access for replacement To access the compressor PCB and/or the PRV the top bracket needs to be removed. To remove the internal top bracket sub-assembly with all components assembled on it (Electronic Control Unit and PRV), remove the 2 screws (a,b) located on the back of the panel and (c,d, e, f) located on the two corners of the top bracket.
  • Page 28 Pressure Relief Valve access and replacement Please ensure the CO2 is disconnected and purged from the machine. To remove the PRV, firstly remove the tubing from hydraulic fitting and afterwards undo the fitting (a) from the PRV.

  • Page 31: Troubleshooting - Diagnostic Guide

    It is normal that the appliance works at a continuously high room temperature Gas leak from the cooling system Contact a specialized technician (refrigerator repairman) or The compressor Marco Beverage Systems works continuously, but the water is not The compressor is faulty Check wirings and voltage on compressor terminals and cold replace the faulty component if needed.
  • Page 32 ISSUE PROBABLE CAUSE SOLUTION pressure too low Restore correct CO pressure (typically about 4 bar / 60 psi) cylinder empty Replace CO cylinder Too low CO volume Water temperature too high because cooling capacity is See refrigeration/equipment specifications vs. volume exceeded by over drawing requirements and reduce amount of glasses taken per given time of install higher volume unit.
