Installation and commissioning 6

1Installation and commissioning

1.1 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.

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

For details, see the planning information on the website www.wmf-kaffeemaschinen.de

Installation and commissioning 7

1.2 Hardware connection and preparatory work

1.2.1 General tasks

Place the coffee machine horizontally on the counter (breadth 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!

All drains must be sloped.

Connect to the power supply

Switch on the coffee machine

1.2.2 Recommended water filter

A WMF water filter is recommended for carbonate hardness above 5 °dKH.

For the WMF 5000S, the –bestmax XL– water filter is recommended in the standard price list.

After measuring the carbonate hardness with a test kit - which is within the sell-by date - cut to size according to the capacity table

(see the User manual which comes with the filter).

Installation and commissioning 8

1.3 Initial start-up with the aid of the technical information

1.3.1 Goal of the technician information

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 cups is changed, filling quantities are to

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

1.3.2 Workflow, technician info:

Set and where necessary change the language

Adjust time and date where necessary
