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-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 tasks

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 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.

Connect to the power supply

Switch on the coffee machine

1.2.2 Recommended water filter

When the carbonate hardness is above 5 °dKH, a WMF water filter should be installed.

For the WMF 1500S+, –bestmax M –is recommended in the standard in the retail 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 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 adjust the time zone as necessary.

Set automatic summer/winter time.
