Page 6: Installation And Commissioning
Installation and commissioning Installation and commissioning Customers on-site connection requirements Necessary preparatory work for electricity, water and drainage connections at the customer‘s premises are to be arranged by the machine owner/operator. The work must be carried out by authorised installation technicians in compliance with general, country-specific and local regulations. The WMF Service engineers may only connect the coffee machine to existing prepared connection points. -
Page 7: Recommended Water Filter
Installation and commissioning Example, Dynamic Milk: all drains must be sloped. Attach the drain tube and rinse hose to the connection angle using cable ties Caution To prevent back-contamination, the hoses MUST NOT make contact with the wastewater. Two position arrows are inscribed on the elbow connector for reference. -
Page 8: Initial Commissioning
Installation and commissioning Initial commissioning 1.3.1 Goal of the Technician's Intro A guided implementation of mandatory basic settings. As simple a start-up of the coffee machine as possible with a high-quality beverage quality. The aim is not to cover all setting options. If for example the settings stored as defaults are changed in the "Operating options"... - Page 9 Installation and commissioning Set and where necessary change the language. Adjust time and date where necessary. The prompt appears asking whether to carry out start-up or not. When Yes: Next step When No: Machine is filled then heat and is then ready for use...
- Page 10 Installation and commissioning Enter the technician PIN. (Since some access to service menus is provided as part of the technician intro; it is used to ensure that only technicians use the start-up intro.) A pure information text page follows. In this way, the setting steps to be performed are explained in detail.
- Page 11 Installation and commissioning Adjust the machine configuration. After processing and confirmation, a restart will be required. The menu items are intended – as they partly build on top of each another- to be processed from top to bottom. (The cooler is only present when it was previously selected in the machine configuration). Menu items which were run through and processed are marked with a check.

Page 22: Power Class
Service Power Class The "Power Class" considers the country-specific heating output versions of the machine, the connection configuration at the grid power terminal, and the current protection on the supply grid side. The Power Class is therefore useful for optimizing utilization and ensuring machine functionality. The Power Class determines the following: Mutual lockout and enabling of components such as the grinder and the heater. -

Page 25: Descaling
Maintenance Descaling Descaling can be performed from the (internal) water tank by the customer or by a technician using the display-guided descaling routine. The mixing ratio is 2 bottles of descaler to 3 bottles of water. Customer descaling: The customer can perform a descaling via the care menu. Technician descaling: The technician can perform a reduced descaling at a higher descaling temperature using Service/service routines. -
Page 26: Antifreeze Protection/Transport Preparation
Antifreeze protection/transport preparation Antifreeze protection/transport preparation This routine is the easiest way to prepare the coffee machine for shipping during winter months. Without needing to open up the coffee machine, the boiler water system and the safety assembly are partially emptied. This prevents any frost damage from a single freezing incident. -
