Risk of damage!
The displays and PCBs are sensible to electrostatic discharge.
• The service technician must be earthed using a grounding strap, ESD
gloves or similar safety measures.
Danger of burns!
Hot parts and water pressure inside the coffee machine (particularly in the
thermoblock and boiler).
• Let the coffee machine cool down before cleaning or disassembly.
• Do not touch any hot parts while checking for leakages.
Danger of steam release!
Several components and pipes of the milk module (particularly in the
hydraulic unit) are under pressure.
• Let the milk module cool down before cleaning or disassembly.
• Do not touch or disconnect any hot parts.
Risk of fire / flammable materials!
The fridge unit contains a highly flammable refrigerant fluid (R600a).
In case of (audible) leakage:
• Keep away any open flames or sources of ignition.
• Don't smoke.
• Let the leaking gas dissipate before any further actions.
• Replace the complete fridge unit.
Possible eye hazard!
The capsule recognition module emits an invisible laser beam.
• Do not stare into the laser beam accidentally or direct it towards other
people around you.
• Do not put reflective objects in the path of the laser beam.
• Do not remove the PCB from the capsule recognition module and look
on the powered laser diode with optical equipment such as a magnify-
ing glass or a microscope.
Danger of flooding in regard to the direct water connection!
• During repair of the coffee machine on-site, turn off and lock stop valve
of the direct water connection.
