3 Warnings

Maximum machine safety is an integral WMF beverage characteristic to which we pay particular attention.

In spite of all our safety precautions however, every machine is potentially hazardous if not operated properly.

This is why – for your own safety – we have summarised the warnings below and highlighted them in grey throughout the instruction manual.

Please also follow the “Safety instructions” on page 88.

For your own safety, please observe the following instructions

 Connection of the machine to site services and starting up for the

first time must only be carried out by WMF customer service technicians.

at all times:

 All maintenance and repair work must only be carried out by

WMF customer services, using original parts.

 In no circumstances should the safety devices fitted be tam-

pered with. Never remove any machine body parts.

 Caution! Scalding hazard!

In the dispensing area for coffee 7, hot water 11 and steam 8 there is a scalding hazard. Take care when the spout or front door is raised: always make sure a cup is in position before dispensing any beverage.

 Caution! Health hazard!

Follow the instructions on the pack when using the cleaning

beverage. The cleaner is corrosive. Cleaning fluid flows out of the combination spout 7 while cleaning is in progress. Wait until prompted by the display before placing cleaning tablets in the manual input.

4 Safety instructions

General notes

1. At the end of the working day always ensure that the shut-off device on the water pipe supply-

ing the machine is closed and the main power switch to which the machine is connected is switched off and/or the plug is removed from the socket.

2. The component-tested safety devices fitted, prevent inadmissable pressure and temperature

rise in the boiler. If the safety valve is activated, the machine should be switched off immediately at the customer’s main switch. Switch off the machine if a boiler malfunction occurs. Contact the WMF customer service department and do not switch the machine on again until the fault has been remedied.

3. This machine is not for use out of doors. In case of freezing the machine should be drained

beforehand to prevent frost damage.

4. Never spray the machine with a hose or steam jet. Clean the surface by wiping with a damp

cloth, or use beverages from our WMF care range.

5. The unit must stand safe at a ground level, on a horizontal and stable base.

Machine shutdown – holidays

1. If the machine is to be shut down for an extended period, a general cleaning should be carried

out beforehand and the grouts collector must be emptied. If there is any risk of freezing, the machine should be drained beforehand to prevent frost damage. In such cases, call in the WMF customer service personnel in good time.

2. After several weeks of shutdown for holidays, we recommend that the fully automatic cleaning

program be run at least twice before the machine is started up again.

Hot water boiler data - see rating plate

The hot water boiler complies with the Pressure Equipment Directive 97/23/EC – Category 1, Module A.

The hot water boiler is subject to neither notification nor licensing. Each hot water boiler is subjected to hydrostatic tests before delivery to the customer.

The German regulation governing steam boilers and the associated technical rules require the owner / operator of such plants to ensure that the safety facilities are carefully serviced and inspected.

The machine / unit complies with all the relevant regulations.

The owner / operator must ensure that the electrical equipment and systems are in safe working order.

Page 10

This device is subject of the directive on waste electrical and electronic equipment (WEEE/EU directive) and may not be disposed of as domestic waste. Please contact your WMF Customer Service for information on proper disposal of the device.

Preventive measures to avoid consequential machine damage

 Any technical device, particularly large fully automatic machines, are a potential source of

danger when operated without supervision.

 We therefore recommend that the operator takes appropriate action to prevent damage, for

instance installing a suitable water detector in the site water supply line.

 If the local water has a carbonate hardness of more than 5° (German hardness), a WMF water

filter must be installed in the supply line to the machine.

 Maintenance intervals depend on how heavily the machine is used and on local water condi-

tions, and should be fixed by agreement with your service engineer. Even in the case of light use, maintenance should be carried out at least once a year and the water filter, if fitted, should be replaced.

7.1 Starting the machine

Before the machine is started up, the main shutoff valve in the fresh water feed line must be opened and the main electrical switch supplying the machine must be turned on.

Turn the key switch 15 to position “1” (On).

After switching on, the machine heats up to operating temperature (about 12 minutes). During the heating-up phase the display shows the following:

When the machine has warmed up, the display shows the following: If the coffee beans hopper and/or ground coffee hopper are full (see chapter 7.2 on page 91) and the machine is ready for operation, coffee and hot water can be dispensed by pressing one of the beverage keys.

7.2 Filling the coffee beans hopper and/or ground coffee hopper

To fill the coffee beans hopper 1 remove the hopper lid and fill the hopper with coffee beans. Then replace the lid to close the hopper. Each coffee beans hopper has a capacity of approx. 1.05 kg.

Note:

Avoid cramming the coffee beans or ground coffee into the hoppers as this can cause machine to malfunction.

Page 13

To fill the ground coffee hopper 2 remove the hopper lid and fill the hopper with ground coffee. Then replace the lid to close the hopper. The ground coffee hopper 2 has a capacity of approx. 500 g.

It is important to top up the coffee beans hopper and the ground coffee hopper before they are completely empty to ensure correct operation of the coffee machine.

7.3 Preparing to dispense milk

In order to dispense milk from the machine, the milk tank supplied (e. g. in the WMF auxiliary cooler or, as shown here, the Tetra Pak) has to be connected to the combination spout 7 of the machine by the milk intake hose 16.

If this is not the case, proceed as follows.

Slide the complete front door 14 upwards until the clamping valve 13 is easily accessible. Do this by grasping the front door at both sides and sliding the front door upwards with gentle pressure (see also chapter 7.5 on page 95).

The milk intake hose 16 has a plastic connector on one end (bottom left in the picture) and a metal nozzle on the other end (top right in the picture).

Page 14

Insert the connector of milk intake hose 16 into the connection provided on the underside of the combination spout 7. Then push the milk intake hose into the guide on the underside of the combination spout 7 to fasten the milk intake hose 16 to the combination spout 7.

Next, feed the milk intake hose 16 through the clamping valve 13 mounting. To do this, pull both ends of the milk intake hose 16 forward and press down into the mounting.

Then guide the metal nozzle of the milk intake hose 16 through the hole which is on the left next to the clamping valve 13. Finally, insert the metal nozzle of the milk intake hose 16 into the milk tank supplied (e.g. in the WMF auxiliary cooler or Tetra Pak).

Always make sure the milk tanks are topped up or replaced in good time, to ensure correct operation of the coffee machine.

7.4 Beverage key selection and labelling

Depending on the machine version chosen, you have either 5 or 9 beverage keys and one hot water key at your disposal (shown here: control panel 5 with 9 beverage keys

17). You can assign each beverage key 17 individually

with your chosen coffee beverages. Around 40 pre-set standard beverages are provided for you (see chapter 8.2.8, page 121) or alternatively you can choose your own settings.

You can label the individual beverage keys 17 with different beverage symbols which your local WMF customer service engineer can replace according to your requirements.

The 2x key gives you access to a second level of keys.

By selecting this key before pressing one of the beverage keys, you can either prepare an additional beverage alternative or call up the two-cup function automatically.

Example: additional beverage alternative

1 cup Espresso

1313

Page 15

1 cup Ristretto

Your local WMF customer service engineer will set up one of these alternatives for you at the time of installation of the machine.

Example: two-cup function

1 cup Espresso

2 cups Espresso are pre-

pared at the same time

Note:

We recommend to switch off the machine while labelling in order to avoid pressing one of the beverage keys inadvertently.

You can also label the beverage keys 17 as you choose. To do this, press on either the left-hand or right-hand side of the key strip and, while still pressing, slide the key strip out sideways until the key strip comes out of its holder.

Remove the key strip from its holder.

You can now replace the existing labels with the readymade labels supplied with the machine. Alternatively, you can print your own labels on plastic, cut to size and use these instead.

Note:

Ensure the black foil is always replaced correctly.

After changing the plastic labels, replace the key strip. To do this, insert the left-hand (or right-hand) edge of the key strip into the holder and press the opposite side of the key strip into the holder as well until the key strip clicks into place.

Important!

This is a supplement to the WMF combiNation S

operator’s manual. The warnings and safety in-

structions in that manual must be observed. The liability conditions set out in that manual apply.

Please also observe all other sections of the combiNation S manual not specially mentioned in connection with the combiNation S4.

8.6.1 General description

There’s no doubt about it: preparing coffee is a philosophy in its own right. But the art is to optimise the individual coffee sensation by using one’s own blends of freshly ground coffee beans.

The WMF combiNation S4 is equipped with four separately controllable coffee grinders. This machine only operates with coffee beans. A small quantity of ground coffee can also be processed via the manual input, if desired.

The machine user guide is the graphic touch screen display. As well as the blend proportions for the four coffee beverages, the main quality factors, such as water quantity and temperature, milk froth quality and quantity are also set via the display. The proportions by weight of the types of coffee used are shown as bars in the diagram.

The WMF combiNation S4 is the ideal machine for use wherever there’s demand for an infinite variety of coffee.

A professional barista!

8.6.4 Four-grinder operating concept

You can set up your individual coffee blends and try out coffee recipes with the aid of the touch screen display.

The procedure is as follows:

When the four-grinder option is selected in the machine data, the following display appears first of all:

The four bars in the display represent the four coffee grinders. The figures in the lower part of the bars indicate the percentage of coffee to be used from each hopper.

All the bars are at zero to start with.

The next step is for you to select the proportions of coffee to be used, by weight. This is done by pressing the desired bars in the touch screen display.

Press once on the corresponding coffee grinder bar to choose one part or press twice to choose two parts. If the bar is pressed three times, the proportion resets to zero.

 Example 1:

You want to prepare a Cappuccino, using coffee from grinder 1 only. So press bar 1 on the touch screen display. The following display appears:

Use the Plus and Minus keys to increase or decrease the total quantity of ground coffee by 15% (for stronger or weaker coffee).

Then press the desired beverage key and the Cappuccino will be prepared, using coffee beans from hopper 1. The percentage is shown in the lower part of the bar.

All the bars reset to zero afterwards and you can program another coffee combination.

2 3

Page 51

130

 Example 2:

You want to prepare a Latte Macchiato, using one part each from grinder 1 and grinder 4 and two parts from grinder 2. So on the touch screen display, press bar 1 and bar 4 once and press bar 2 twice. The following display appears:

Use the Plus and Minus keys to increase or decrease the total quantity of ground coffee by 15% (for stronger or weaker coffee).

Then press the desired beverage key and the Latte Macchiato will be prepared with the correct proportions of coffee beans from the three hoppers. The percentage for each hopper is shown in the lower part of the bar.

All the bars reset to zero afterwards and you can program another coffee combination.

8.6.5 Beverage settings

You can also refer to the Beverage Settings chapter in your combiNation S operator’s manual, with one small difference:

In the second step of the setting options, you can select the proportions of coffee to be used by weight for the default setting for each beverage. To do this, press the desired bars directly in the touch screen display (see chapter 8.6.4 Fourgrinder operating concept on page 129). The values set are then transferred to the default setting for each beverage.

8.6.6 Special features

- The WMF combiNation S4 has four coffee beans

hoppers with a bayonet fitting and slide.

- The removable beans hoppers are easy to wash out

and clean.

- There are no ground coffee hoppers on the combi-

Nation S4.

12 WMF customer service

WMF’s comprehensive service network allows every area to be reached in a short period of time. Our personnel are experienced experts and carry special tools and the original spare parts required at all times, so that malfunctions can be remedied on the spot.

Please bear in mind that this is a professional commercial coffee machine. A machine of this

type requires regular maintenance by our WMF Customer Service. The maintenance interval depends on how heavily the machine is used, but maintenance should be carried out at least once a year.

13 Liability

WMF shall be liable for legitimate defects as to quality as follows:

Any beverages delivered or any services rendered showing a defect as to quality within the period

of limitation shall be, at WMF’s reasonable discretion, repaired or rendered again, if the cause of the defect as to quality had already been present when the risk was passed.

Claims for defects as to quality are subject to a limitation period of 12 months. This period shall

start with the day when the risk is passed. The above period shall not apply in case there are longer periods required by the German Civil Code (BGB).

If putting the machine into operation is delayed for longer than four weeks due to reasons that are beyond the control of WMF, the warranty period shall begin four weeks after the machine being delivered to the customer.

The buyer shall immediately give written notice of defects as to quality to WMF. Replaced parts shall pass into the ownership of WMF.

At first WMF shall always be given the opportunity for a subsequent performance within a reasonable period. The buyer shall make available the rejected object to WMF.

Page 72

151

We are not liable:

- for any components that are subject to a normal wear and tear. This includes but is not limited

to gaskets and washers, ribbons, and proportioning devices;

- for defects caused by atmospheric influences, deposit of boiler scale, chemical, physical,

electro-chemical or electrical influences, unless these defects are attributed to a fault of WMF;

- if a water filter is dispensed with, although the on-site water regime requires the use of a water

filter, and this results in defects. It is pointed out to the customer in the respective acknowledgement of order, whether the use of a water filter is required;

- for defects resulting from the failure to comply with the instructions relating to the handling,

maintenance and attendance of the device (e.g. operating and maintenance instructions of WMF laid down in the operating manual of the respective percolator type);

- for defects resulting from the inappropriate or improper use, from the failure to use WMF

14 HACCP cleaning concept

Our aim in providing this customer information is to assist you in complying with the statutory food hygiene regulations relating to milk beverages as they apply to WMF coffee machines. The German food hygiene ordinance dated 5th August 1997 places a legal obligation on you to ensure that your customers are not exposed to any health hazards due to consuming foods supplied by you.

The HACCP (Hazard Analysis Critical Control Points) concept introduced by these regulations requires you to carry out a hazard analysis of your business. The aim of this analysis is to identify hazard points relating to food hygiene and remedy them. Monitoring and if necessary testing procedures have to be established and implemented to this end.

If properly installed, maintained, cared for and cleaned, WMF coffee machines fulfil the conditions of the above mentioned requirements. If the machine is not properly cared for and

cleaned, dispensing of milk beverages, even from WMF coffee machines, becomes a hazard point from a food hygiene point of view.

Please therefore bear the following points in mind when planning your HACCP concept:  Disinfect your milk system once a day

It is essential to follow the operating instructions with regard to cleaning the milk dispensing system. That ensures your system is as sterile as possible at the start of operation.

 Start up each time with a fresh pack of cooled long-life milk

Long-life milk in its original packaging is free from harmful germs as a rule. Never start working with a milk pack which has already been opened. When opening the fresh milk pack, it is important to ensure absolute cleanliness. Otherwise, dirty hands or scissors or knives can introduce germs as soon as the pack is opened.

 Keep the milk cool

At the start of operation the milk should be at fridge temperature (approximately 6 – 8 °C). The warmer the milk, the faster germs can multiply.

- Cooling is not necessary provided the pre-cooled fresh milk is used up within 3 hours at

most (equivalent to about 20 cappuccinos from 1 litre of milk, depending on the machine setting). The milk does not warm up to a critical level during this time.

- If your milk consumption is less than this, the milk should be cooled while in use. WMF AG

offers various options for this purpose (e.g. the WMF auxiliary cooler or the WMF milk cooler). The same principle applies, however: the milk must be pre-cooled. Cooling warm milk takes some time and should therefore be done before the milk is opened. Always keep a “spare” unopened pack of milk in the WMF cooler or take a fresh pack from the cold storage room or fridge.

- If it is not possible for you to cool the milk during operation and your milk consumption is

very low, intermediate cleaning should be carried out at least every time the milk pack is changed.

HACCP cleaning concept

Use only cooled long-life milk, as otherwise health hazards due to micro-bacteria cannot be ruled out

Cleaning steps: 1. Run the fully automatic coffee machine cleaning program and empty the grouts collector

5. Clean the milk frother (leave in cleaning fluid for 5 hours)

6. Intermediate cleaning or replace the milk frother after every 4 hours’ operation

(essential with low throughput and when using uncooled milk)

7. General cleaning of the machine, i.e. cleaning the panels, drip tray, manual input, etc.
