Installation and commissioning 6

1Installation and commissioning

1.1 Customer’s on-site connection requirements

Any necessary on-site preparatory work for electricity, water, and drainage connections at the customer‘s premises is to be arranged by the machine owner / operator.

The work must be carried out by authorized 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.

WMF Service is neither authorized nor responsible for carrying out any work on-site prior to connection.

For details, see the planning information on the website www.wmf-coffeemachines.com.

Notes

-Electrically conductive counter surfaces must be earthed

-Unplug the mains plug before disconnecting the mains voltage across the cold appliance plug

1.2 Hardware connection and preparatory work

1.2.1 General activities

Place the coffee machine horizontally on the counter (width and depth); adjust feet where adjustable

Connect the water infeed

Water filter needed? If „Yes“–connect (for details, see the following chapter)

Connect the drain –use angle 33 2165 8000 from horizontal to vertical.

Installation and commissioning 7

Example, Dynamic Milk: all drains must be sloped.

Attach the drain tube and rinse hose to the elbow connector using cable ties

Attention:

To prevent back-contamination, the hoses MUST NOT make contact with the wastewater.

Two position arrows are inscribed on the elbow connector for reference.

Connect to the power supply

Switch on the coffee machine

Installation and commissioning 8

1.2.2 Recommended water filter

We generally recommend the use of a water filter.

Using the WMF coffee machine without a suitable water filter can cause damage (e.g. due to lime scale buildup).

Use a test kit that has been properly stored and has not exceeded its expiration date to test the overall and carbonate hardness of the line water (before the

water filter).

Enter the measured values in the WMF Aquatool app and install the water filter recommended for your water consumption and type of coffee machine.

Please note the variance in line water values for the filter capacity shown in the app. (plan for buffer)

1.2.3 Interface plate for electrical connections

The back of the machine has cut-outs for the following electrical connections:

Accounting via serial or MDB interface

Potential equalization

Cooler empty message / temperature

Mobile Station Waste (wastewater)

Mobile Station Fresh (fresh water tank)

Audio In

Audio Out

Detecting the cleaning agent

Network

Installation and commissioning 9

1.3 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" menu or if the position of beverage buttons is changed, cup volumes are to be

changed, this must take place after the intro has concluded.

1.3.2 Workflow, Technician's Intro

Set and where necessary change the language.

Set and adjust the time zone as necessary.
