3 Warnings

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

In spite of all our safety precautions, 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. This is why it is important to follow the “Safety instructions” given on page 81.

Important instructions which must be observed for your own safety

Connection and commissioning of the coffee machine may only be undertaken by the WMF customer service team.

Maintenance and repair work on the machine may only be undertaken by the WMF customer service team using original spare parts.

Installed safety devices must not be altered for any reason. No parts of the outside of the machine should be removed.

Caution! Risk of being burned and scalded At the spout where hot water 11 and coffee 6 comes out there is a risk of being burned and scalded. Always ensure that there is container placed under the drinks spout! Ensure that the container is stable and do not leave it unattended. After switching on it is possible that hot water comes out of the hot water- 11 and coffee spout 6 during the warm brewing phase. Never reach under the spouts while cleaning is in progress.

Caution! Health hazard! Follow the precautions on the packaging when using the cleaning product. The cleaning granulate is an irritant. Cleaning fluid flows out of the coffee spout 6 while cleaning is in progress. The protective panel provided should be fitted (see picture on page 136). Do not leave jugs or cups underneath the coffee spout 6 while cleaning is taking place. Wait until prompted by the display before placing cleaner granulate in the brewer.

Caution! Danger of crushing! Never put your hand into the ground coffee hopper 1 or the granulate cleaner reservoir 3 when the machine is in use and the power is switched on!

Caution! Electric shock hazard! Moisture can cause short circuits. It is therefore essential not to allow fluids to enter the inside of the machine housing . Under no circumstances should the machine be opened up. Never put your hand inside the machine interior or reach inside with a tool.

81

4 Safety instructions 1 Always ensure that the main water tap in the supply line is closed when the machine is

switched off and that the main power switch outside the machine is off or the mains plug is disconnected from the socket as there is a risk of water escaping from the machine.

2 The installed component approved safety equipment prevents an impermissibly high pressure

or temperature increase in the hot water boiler. If the safety valve is actuated one-time then the machine must be switched off at the local main switch and the main stop cock on the drinking water supply line closed. Switch off the machine if any faults arise on the hot water boiler. Inform the WMF customer service team and do not switch on the machine again before the fault has been removed.

3 Do not use the machine in the open air. The water system must be emptied if there is frost. 4 The device must not be sprayed with a water hose. Use of steam cleaning, steam jet devices

and similar equipment for cleaning purposes is not permitted. Clean the surface of the coffee machine using a soft cloth or by using products from our WMF care range.

5 The device must be set on a flat, level and secure surface. 6 Do not let children near the machine! 7 Do not use the machine if it does not work properly or if has been damaged Shutting down the machine – company holidays 1 If the machine is to be shut down for an extended period, a general cleaning should be carried

out first and the grouts collector should be emptied. Drain the machine first to prevent frost damage if there is any risk of freezing. A WMF Customer Service Technician must be called promptly in such cases.

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

program be run at least twice before the machine is started up again. Regulations Refer to rating plate for boiler data. 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 operator of such plants must ensure that the safety devices are carely serviced and inspected.

82

The machine complies with all the relevant regulations. The operator must ensure that the electrical equipment and systems are in safe working order, (e.g. BGV A3). 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. Preventative measures against suffering damage to the machine • There are always operating dangers associated with every technical device, particularly from

large fully automatic machines which are operating unobserved.

• We therefore recommend that the operator take reasonable measures to prevent damage occurring to the machine, for example by installing a suitable water hydrant in the drinking water supply on-site.

• If the water used in the machine has a carbonate hardness above 9°, a WMF water filter must be fitted in the supply line. Otherwise limescale can cause damage to the machine.

• Maintenance intervals depend on how heavily the machine is used and on local water conditions, and should be fixed by agreement with your WMF Customer Service Technician. 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.

Installation clearance

For operating, service and safety reasons the machine should be installed with clearance of not less than 50 mm from the back and sides from the building or non-WMF components. A clear height of 1100 mm from the top of the supporting surface should be ensured. The height of the supporting surface from the floor surface should be not less than 700 mm and not more than 900 mm. If the machine connections are to be routed down through the counter, remember also to allow space for the connections. These may restrict the available space below the machine.

Water filter installation dimensions W × H × D

Standard: 250 × 500 × 400 mm Jumbo: 290 × 670 × 420 mm

* The site electrical system must comply with IEC 364. For greater safety, an earth leakage circuit breaker with a rated fault current of 30 mA to EN 61008 should be fitted in the supply line to the machine. In the vicinity of the machine, for a single-phase connection a shockproof socket and for a three-phase connection a 5-pole CEE/CEKON socket to EN 60309 should be fitted. If the power lead to this machine is damaged, it must be replaced by WMF customer service or a similarly qualified specialist. If the machine is permanently connected on site, an all-pole circuit breaker (main switch) to EN 60947 with not less than 3 mm contact opening should preferably be fitted ahead of the machine. In the case of a flexible connection, the circuit breaker is recommended. The power lead must not be allowed to come into contact with hot components. The main switch and socket are part of the customer’s system. The machine must not be installed with a fixed site connection if used with a trolley (mobile station).

85

7 Operation

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. 7.1.1 Switching on manually Turn the key switch 9 to position “1” (On).

After switching on, the machine heats up to operating temperature (about 5 minutes). The first time a quantity of coffee is selected for storage (see chapter 7.5 on page 89), a hot rinse program is executed.

Caution! There is a danger of burning and scalding in the

hot water 11 and coffee 6 dispensing area. During the heating-up phase, the display shows the following:

When the machine has warmed up, the display shows the following: Coffee cannot be dispensed at this stage. First of all, the ground coffee hopper has to be filled (see chapter 7.2 on page 86) and a quantity of coffee selected for storage (see chapter 7.5 on page 89) before the machine is ready for operation. Fresh coffee is then brewed into the storage urn, ready for dispensing.

In the case of coffee machines for self-service use (see chapter 8.3.5 on page 101), when the machine has warmed up, the display shows the following: Coffee cannot be dispensed at this stage.

First of all, the ground coffee hopper has to be filled (see chapter 7.2 on page 86) and a quantity of coffee selected for storage (see chapter 7.5 on page 89) before the machine is ready for operation. Fresh coffee is then brewed into the storage urn, ready for dispensing.

86

7.1.2 Switching on via the timer The coffee machine can be switched on automatically via the “Timer” function in the machine selection menu. Times are assigned to the day of the week and are not controlled by the date. For settings, refer to chapter 10 Timer functions on page 120.

7.1.3 Switching on via display (adjustments to be made by the service team) By touching the Standby Display (WMF-Logo) the switch-on soft key appears. The coffee machine now can be switched on by touching the soft key . If you have allocated access authorisations (PIN numbers) (see chapter 8.4 on page 103) you will be asked for your PIN number.

7.2 Filling the ground coffee hopper To fill the ground coffee hopper 1 remove the hopper lid and fill the hopper with ground coffee. Then replace the lid to close the hopper. The ground coffee hopper 1 has a capacity of approx. 2.2 kg.

Note: It is important to top up the ground coffee hopper before it is completely empty, to ensure correct operation of the coffee machine.

7.3 Beverage key selection and labelling A total of 4 beverage keys 13 and one hot water key 10 are at your disposal (see chapter 7.7 on page 94). You can assign each beverage key individually with your chosen coffee beverages. You will find a master for labelling the beverage keys on our Web site at www.wmf.de. You can use it to design your own labels and print them out on transparencies.

1

87

Note: We recommend switching off the machine when changing the labels, to prevent a beverage key being pressed in error. Otherwise, there is a danger of burning and scalding.

You can label the beverage keys 13 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 labels which you have made yourself. You can print your own labels on plastic, cut to size and insert in place.

After changing the plastic labels, replace the key strip. To do this, insert the key strip into the holder, pressing evenly on both sides of the key strip until it clicks into position into the holder.

7.4 Adjusting the height of the front panel (optional)

Note: Front panel height adjustment is only available as an option. When you dispense a cup, pot or mug of coffee, the front panel 12 remains fully down all the way to the stop. The key lights in the Cup, Pot and Mug beverage keys are lit, and the key light for Jugs is extinguished. To fill jugs and containers over 140 mm high, the complete front panel 12 has to be pushed fully up all the way to the top. The key lights in the Jug and Hot water 10 beverage keys are lit, and the key lights for Cup, Pot and Mug are extinguished.

13

12

88

Caution! There is a danger of burning and scalding in the

hot water 11 and coffee 6 dispensing area.

Grasp the lower part of the front panel and slide it all the way up to the top, using gentle pressure. This enables the clear height to be increased to 280 mm. In addition, the coffee spout 6 can be removed (for instance, to fill insulated jugs) but this is not possible in the case of self-service machines.

Caution! The coffee spout 6 and the hot water spout 11 are hot. There is a danger of burning. Beware in the coffee 6 and hot water 11 dispensing area: there is a danger of scalding.

Important: For safety reasons, it is not possible to dispense a cup, pot or mug of coffee when the front panel is in the raised position.

The corresponding keys are disabled. On sliding the front panel back to the fully down position, the keys are enabled again.

89

7.5 Selection of quantity of coffee for storage Due to the design of the machine, a quantity for storage has to be selected before coffee can be brewed and dispensed. The brewer unit in the WMF combiNation F allows brew quantities of 1 and 2 litres of coffee to be prepared. One or more brews are carried out until the urn contains the desired quantity. The following actions are shown on the display: Storage urn emptying Storage urn flushing taking place Brewing taking place (see display on the right) By pressing the soft key you can access a second level, where there is a selection menu. The following display appears: Now press the soft key to select a quantity of coffee to be prepared. You can also go directly into the quantity of coffee selection by pressing on the storage urn. The following quantity preselections are available and can be selected by means of the soft keys:

90

7.5.1 Automatic quantity control

There is a choice of 3 alternatives: Half full, Full (economy) and Full (power)

- Half full Two litres of coffee are transferred to the storage urn to begin with. If the coffee level in the urn falls below 1.5 litres, the WMF combiNation F starts automatic refill brewing of fresh coffee (1 litre). Should the coffee level fall below 1.0 litre, coffee dispensing is disabled. No more coffee will be dispensed until refill brewing of fresh coffee has taken place. Press to confirm your selection.

If you choose “Half full” as the quantity preselection, instead of the empty storage urn, the display shows:

If coffee has already been brewed into the storage urn, the display shows the current level in the urn. In this example, the urn contains 1.6 litres of coffee:

Note: The display of the actual contents of the storage urn

has a display tolerance of up to 0.3 litres. The quantity of coffee currently stored in the urn is displayed in litres in every quantity preselection stage (except for coffee machines in self-service operation mode, see chapter 8.3.5 on page 101).

91

- Full (power)

Four litres of coffee are transferred to the storage urn to begin with. If the coffee level in the urn falls below 2.1 litres, the WMF combiNation F starts automatic refill brewing of fresh coffee (2 litres).

Note:

Should the coffee level fall below 1.0 litre, coffee dispensing is disabled.

No more coffee will be dispensed until refill brewing of fresh coffee has taken place. Press . to confirm your selection.

If you choose “Full (power)” as the quantity preselection, instead of the empty storage urn, the display shows:

- Full - economy This is the same version (see “Full power”) with a lower hourly output and more economical use of the ground coffee. Press . to confirm your selection.

If you choose “Full - economy” as the quantity preselection, instead of the empty storage urn, the display shows:

Note: Coffee dispensing is briefly disabled during refill brewing.

92

7.5.2 Manual quantity control

- 1 litre manual One litre of coffee is transferred to the storage urn to begin with. If the coffee level in the urn falls below 0.5 litres, coffee dispensing is disabled. Automatic refill brewing does not take place. In other words, each brew has to be started.

Note:

Coffee dispensing is disabled during brewing. The rest of the coffee can then be removed manually (see chapter 8.6 on page 106). Press . to confirm your selection.

If you choose “1 litre manual” as the quantity preselection, instead of the empty storage urn, the display shows:

- High-speed brewing (adjustments to be made by the service team) Brewing of the maximum possible quantity can be activated manually via the display, if required. This setting is activated until touching the soft key again. Important: the quantity preselection must be preset to an automatic setting. Brewing will start again automatically just as soon as at least 1 litre of coffee can be removed.

- Stand-by (zero litres)

This setting should be selected if you want to empty the storage urn completely and no refill brewing is required. Coffee stored in the urn is dispensed until dispensing is disabled on reaching 0.5 litres. Press to confirm your selection.

If you choose “Stand-by (zero litres)” as the quantity

preselection, instead of the empty storage urn, the display shows:

93

7.5.3 Quantity control using the timer You can program different quantities for brewing and storage at different times as required, by using the Timer function in the machine selection menu. Times are assigned to the day of the week and are not controlled by the date. For the settings, refer to chapter 10 on page 120.

7.6 Coffee dispensing (cup/mug/pot/jug) Once the ground coffee hopper has been filled (see chapter 7.2 on page 86), the desired storage quantity has been selected (see chapter 7.5 on page 89) and a brew has already taken place and the coffee is in the storage urn 2, the machine is operational and coffee can be dispensed by pressing a beverage key. The display shows the empty storage urn or the symbol for the storage quantity you have selected (see chapter 7.5 on page 89): If there is no coffee in the storage urn 2 but, the following message is displayed:

Caution!

There is a danger of burning and scalding in the area of the coffee spout 6.

94

11 Care of the machine Daily cleaning of the coffee machine is very important in order to ensure correct operation of the machine and optimum coffee quality. Accordingly, 26 hours after switching on the machine, a message will appear in the display 4 reminding you to carry out daily cleaning. To ensure the cleaning program is carried out, after a further 24 hours the machine will automatically halt beverage dispensing if the cleaning program has not yet been run. In this case, the cleaning program must be run in order to operate the machine again. If the machine is switched off without cleaning after brewing and if more than 26 hours have elapsed since it was last cleaned when it is switched on again, then the machine will remain blocked after warming up. The cleaning program must be run before the machine can be operated again.

Caution! There is a danger of scalding and burning in the area of the coffee spout 6 and the hot water spout 11, in particular when the front panel is in the raised position and when the coffee spout 6 has been removed.

Caution! Health hazard! Follow the precautions on the pack when using the cleaning beverage. The cleaner is corrosive. Cleaning fluid flows out of the coffee spout 6 while cleaning is taking place. The cleaning adapters must be fitted. Take care not to leave jugs or cups underneath the coffee spout while cleaning is in progress. Wait until prompted by the display before placing cleaner granulate in the manual input.

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), e.g. pursuant to § 479 Sec. 1 BGB (right of recourse of the contractor), 438 Sec. 1 No. 2 BGB (buildings and things for buildings) and § 634a BGB (defects of construction). 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.

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 genuine spare parts or from the faulty installation by the buyer or a third party, or from a faulty or negligent handling; and for consequences from modifications or repair works that were made improperly and without our consent by the buyer or a third party.

Claims for damages by the buyer, irrespective of their legal grounds, particularly on account of violations of the contractual obligation and on account of tortious acts, shall be excluded. The above exclusion shall not apply in so far as there is a mandatory liability, e.g. in case of giving warranties as to quality or durability, pursuant to the German Beverage Liability Act, in cases of wilful acts, of gross negligence, of fatal injuries, of bodily injuries or injuries to health, or in case of any violation of substantive obligations from this contract.

5/5.2 Tips and Hints “Service Routines”

5/5.2.1 Urn calibration The probe must be cleaned before calibration. Switch off the boiler heater and drain the storage urn. Drain the hot water from the boiler via the jet and rinsing valves, the storage urn and the drain and coffee output valves (this takes about 130 seconds). Record the probe value in the empty state. In the idle position of the brewer, the outlet rinsing valve fills the brewing chamber. The piston then moves to the brewing position and the brewing valve opens and the drain and coffee-output valves remain open together for about 30 seconds. The digital values are then recorded sequentially up to the 4.0 litre mark. After this, the actual level in the storage urn can be measured. If the newly recorded calibration curve is strictly monotonous, it can be accepted. If you do not want to accept the new curve, the default values can be used.

Error handling The signal from the controller is monitored for plausibility (lower value 37 digits, upper value 235 digits). Any errors are shown on the display. The number of detected errors is stored in the error memory.

5/5.2.2 First run up The internal flags in the machine are reset. The first startup is treated like switching the power off and on again. A "Reset" event is always recorded in the laptop error memory.

5/7.2 Front door, alignment and ease of movement The front door is tilted at an angle of 5° and moves parallel to the machine and about 1 mm away from it. The front door is carried on two parallel guides to permit it to be raised and lowered. These guides are 397 mm apart (set in the factory). Any subsequent adjustment of the guide spacing must always be carried out on the machine side. For this purpose, there are two movable sheet-metal pieces, secured with M3 screws, at the top and bottom of the guide. For adjustment, remove the machine cover and take out the grounds catcher and then slightly loosen the M3 screws. Then move the front door up and down so that the guide can adjust itself to the correct spacing. Then tighten the M3 screws again. The distance between the front door and the machine can be adjusted on the left side by moving the locking bracket within its elongated holes. This bracket is located at the top left, at the rear of the pull-out module. The distance between the front door and the machine can be adjusted on the right side, after removal of the side cover, by moving the guide mounting bracket within its elongated holes. If the distance between the guides is adjusted correctly, the built-in gas-pressure spring should move the front door upwards by about 1/3 of its total travel. It should be easy to move the door the rest of the way by hand.

5/7.3 Adjusting the inlet nozzle The factory setting for the outlet cap is with the opening facing downwards. The opening should be turned 180 upwards for the “Tchibo Quick” chocolate product (easily pourable product).

5/8 Maintenance

5/8.1 Industrial safety

5/8.1.1 Goggles The TZW Industrial Safety department has urged us once again to point out that for your own safety you should wear eye protection (goggles) when carrying out descaling.

5/8.1.2 Safety instructions Please ensure that you follow the instructions below when carrying out maintenance or repairs: The coffee machine must be disconnected from the mains.Before beginning any maintenance or repair work, first remove the mains plug from the socket or switch off the remote power switch and make sure the machine is currentless. The coffee machine must be depressurized.Before doing any work on the boiler or pipework, close the water inlet and open the dispensing valves or the safety valve and leave them open while carrying out the work. Electrical safety devices must be properly connected.Make sure that all safety devices provided (fuses, temperature limiter) are properly connected. It is not permissible to bridge or bypass safety devices. Safety valve functioning should be tested. Whenever you start up a machine, check the safety valves provided (excess pressure and ventilation). Operate them yourself and make sure they are not obstructed.

5/8-2

Retrofitting, module feet If the drip tray projects over the edge of the mounting surface or is mounted on feet, the bracket 33 2121 4000 (see picture below) must be installed below the drip tray for safety reasons.

Caution! SAFETY RISK! If this bracket is not fitted, users may come into contact with wiring with only basic insulation.

5/8.2 General notes For the combiNation F, just as for all other machines, we recommend that maintenance be carried out every six months. At the latest, the first maintenance should be carried out after 25,000 litres of water have been used.

The maintenance activities and the maintenance sets are designed on the basis of the above period or amount of water.

Maintenance of the boiler and water system and of the valves should be carried out every 12,500 litres or every six months. Maintenance of the brewer and the storage urn should be carried out after a further 12,500 litres or a further six months.

This means that the boiler, water system and valves on the one hand, and the brewer and storage urn on the other hand, are each inspected every 25,000 litres.

The following list of maintenance activities does not include secondary tasks (such as removing and installing covers, greasing gaskets with silicone grease, greasing spindles and bearings with lubricating grease, mixing descaling and cleaning solutions).

5/9.1 Installing the „choc connection” retrofit moduleThe combiNation S to which a chocolate dispenser is to be fitted may be either of two versions.

The harness and the tubes may already be fitted if the “Choc connection” module was also ordered for the machine via the Export Department (possible since the beginning of April 2002). The pre-installed tubes and the fitted harness are located in the area behind/below the grounds shaft. If this is the case, the steps marked * can be omitted.

If the “Choc connection” module was not integrated with the machine at the factory, the additional module 33.3307.6000 should be retrofitted.

5/9.1.1 Instructions including fitting the harness

Before starting work, be sure to unplug the mains power supply, depressurise the boiler and close the stop valve in the supply line to the machine.

(1) Remove the design side panel at the right (2) *Dismantle the GCH boiler cover (3) *Dismantle the power stage (4) *Break out the rectangular opening and deburr with a file

4/4 Timer selection

The timer handles routine tasks such as switching the machine on and off, preselecting the quantities for the storage urn, initiating cleaning of the machine or switching to self-service mode. Manual actions executed with the button switch or on the touch-screen display are executed with the same priority as the timer actions. The timer is a weekly timer and up to 16 switching actions can be programmed for each day of the week.

If you programme the timer to switch the machine off at a certain time and a cleaning operation is running at this time, the machine is not switched off until the cleaning operation has been completed. Changes to the preselected quantities for storage are effective with the machine switched off. The preselected quantities for storage remain stored even when the machine is switched off. Brewing of coffee is disabled 5 minutes before the start of a timer-programmed cleaning operation.

Pressing the timer button in the selection menu causes the following to be displayed.

If a setting PIN has been allocated, only the Timer status OFF or ON can be selected here. The setting PIN must be input in order to access all the other options.

Now if the user sets a PIN for one level and no PIN has yet been allocated for the higher levels, that PIN is accepted for the higher levels. For example: PIN for the “Settings” level is then also accepted for the „Accounting“ level.

If the user cancels the PIN number for one level (input PIN ‘0000’), the PIN numbers for the lower levels are thus also cancelled.

4/8 Rights - authorisations/PIN The combiNation F access authorisation system limits access to the Selection menu if required. There are a total of 6 levels of access authorisation:

Designation Content Info Generally accessible information, not protected by a

PINCleaning Cleaning, setting the milk froth quality, selecting

allocation/access rights Service*) Service mode

*) It is not possible to set a PIN number for Service level.

The Service engineer can use the Config Tool to set extended PINs, for example a PIN giving access to a non-clearable unit accounting counter. Whole menus can also be blocked.

A specific PIN number can be allocated for levels 1 to 3. Levels with the same PIN are treated as the same. If the PIN number “0000” is allocated, no PIN will be requested for the corresponding level and access is unrestricted (Level 1 as a rule).

PIN numbers are hierarchical. That means for instance that the PIN number for Level 2 is also valid for Level 1, but not for Level 3. The Service PIN allows access to all levels.

The PIN number for Service (Service PIN) should never be revealed! This PIN number opens up the setting options to parameters that should not be accessible to the customer or coffee firm representatives. The Service PIN is stored on file by the Service Manager.

4/10.1 Machines without accounting/vending machines Any amount of coffee can be dispensed from the storage urn(s) without accounting with the aid of the manual dispensing button. The storage urn(s) can be completely emptied.

Products dispensed in the above manner are not recorded.

4/10.2 Machines with accounting/vending machines Machines with accounting and vending machines have the buttons "All free" and "Next product free" in addition to the button "Drain urn".

Selecting the button "All free" disables the accounting. This can be used, for example, by the service engineer when setting up the machine.

Selecting the button "Next product free" disables accounting for the next product which is dispensed. This can be used, for example, for dispensing a pot of coffee for the "boss". Accounting is enabled again after the product has been dispensed.

We strongly recommend that this function be protected against unauthorised use by assigning an accounting PIN to it.

Products dispensed in the above manner are not recorded.

4/12.2.4.5 Descaling programme

The descaling (deliming) sequence is started in the Service routines.

Start or Interrruption

Boiler is heated to set temperature.

Descaling programme is running. Press EXIT to cancel if desired.

The programme can be repeated several times. After the 5th repeat the descaling programme will be cancelled.

After descaling, the hot rinsing programme is carried out before the first brewing cycle, as a precaution.

When opening up any screwed connection in the boiler and pipework system, the safety procedures must be observed and appropriate steps taken to check that it has in fact been completely depressurised, as indicated on the pressure gauges.

The instructions in chapter 1/3 “Safety instructions” and chapter 5/8.1 “Industrial safety” must always be fully observed.

Descaling see 5/8.5 Maintenance/ descaling part 5 “Service”

Safety instructions 1/3

Industrial safety 5/8.1

4/12 Service


4/12-23

Descaling is divided into three operations: Depressurising Descaling Rinsing

Each of these operations can be called up independently via the “Descaling” service routine.

To depressurise, as much cold water as possible is fed through the flow heater as quickly as possible, via the jet valve and brewing valve (without the aid of the espresso pump). Heat transmission from the heated steam boiler quickly reduces the steam pressure in the boiler.

When the steam boiler pressure on the pressure gauge falls to 0 bar, this shows that the boiler has cooled to < 100 °C. The water supply to the machine can be shut off while depressurising is taking place, in order to reduce the pressure in the flow heater as well. Once the brewing pressure gauge drops to 0 bar, depressurisation is complete.

The safety precautions must be observed when opening any screwed connections in the boiler and pipework system. Use appropriate means (such as opening the machine steam cock) to check that depressurisation is complete as indicated by the pressure gauges.

Credit-pool mode This mode is needed if credit is controlled by the cash register and several machines can dispense the same products. If credit-pool mode is set to “Yes”, the machine operates with credit interrogation. Each time a product key is pressed, the machine asks the external MC3 or the ISB whether a credit exists. If a credit exists for the requested product line, the combiNation dispenses the product. Credit-pool mode can process only free credit correctly when used with the ISB. When used with an external MC3, it can process both credit types correctly.

Waiter-credit mode In this credit mode, the credit is stored for both the product and the waiter. Only the waiter who created the credit on the cash register with his waiter key can dispense products from the machine on credit with his waiter key.

Credit pen mode If Credit pen mode is set to “Yes”, dispensing on credit is possible, for all credits, only if the Credit pen is inserted in the machine. The default Credit pen for the SE is key 61.

2/2.2 Boiler system

The boiler provides the hot water needed for brewing coffee and for dispensing hot water. The boiler temperature is monitored by the controller with the aid of a temperature sensor. The boiler heater is switched on and off by a circuit breaker which disconnects all phases of the supply voltage. Overheating of the boiler in the case of a error is prevented by a safety temperature limiter which switches off all phases of the heater. If the pressure in the boiler rises to an impermissible value as the result of a error, the excess pressure is discharged with the aid of the safety valve.

2/2-7

2/2.2.2 Boiler heaters

The heaters heat the water in the boiler to the selected temperature. The desired temperature can be set in the adjustment programme. When the controller detects that the water temperature is below the desired value, it switches on the heaters until the water temperature rises above the set value. The boiler heaters are not normally switched on during execution of the Service programme. The only exceptions to this are the descaling programme, the test step "boiler heaters" and the Product data. When the machine is switched on, all

brewing operations and dispensing of hot water are disabled until the water in the boiler reaches the specified temperature (warm-up phase). Boiler heaters 3x 4.5 kW tubular heaters, delta connection Rated voltage per heater

Engineering


2/2-8

2/2.2.3 Temperature sensor

An NTC resistor is used as a temperature sensor. Its resistance varies inversely with the water temperature (low water temperature = high resistance and vice versa). Due to the position of the sensor, the indicated temperature is about 4K lower than the actual water temperature. For example, at an indicated value of 92 °C, the hot water leaving the boiler has an actual temperature of 96 °C.

Error handling for the temperature sensor Breakage of the sensor Overtemperature If either of these errors occurs, any brewing operation or dispensing of hot water which is currently running is terminated immediately and further operations of these types are disabled. The programme routine for the temperature sensor remains active. If the temperature returns to within the permissible range, brewing and dispensing of hot water are again enabled. Errors are shown on the display. The number of detected errors is stored in the error memory.

When the temperature sensor has cooled down, they can be unlocked by pressing the reset knob. The contacts are also opened and locked if the hydraulic sensor system develops a leak or if the complete STL is cooled to a temperature below –5 °C. In the latter case, warm the sensor to 20 °C and then press the reset knob to release the contacts.

2/2.2.7 Boiler safety valve

If the boiler pressure rises to an excessive value as the result of a error, the excess pressure is released via the safety valve. During heating of the boiler, water escapes from the safety valve due to thermal expansion.

Error handling for safety valve The safety valve is intended to prevent the pressure in the boiler from reaching a dangerous value. The escape of water through this valve during heating of the boiler is normal and does not indicate the presence of a error. Safety valve 3.2 bar

2/3-1

2/3 Brewing unit

In the brewing unit below the ground-coffee portioner (GCH), the piston opens the filling aperture for ground coffee when it is in its idle position. For each batch of coffee to be brewed, the appropriate amount of ground coffee is measured and rinsed into the brewing chamber. The piston then moves to the brewing position, sealing the brewing chamber. During the subsequent brewing operation, brewing water flows through a distribution sieve onto the ground coffee in the brewing chamber. After the brewing operation, the piston

moves via the pressure-release position to the rinsing position and the exhausted ground coffee is rinsed out of the chamber. The annular rinsing ring ensures effective cleaning of the brewer. The idle position of the brewer is the rinsing position.

The hot water button is connected to the front panel by a cable routed behind the glass panel. For control purposes the hot water button is an extension of the dispensing buttons on the control panel.

The following four portioning alternatives are available for hot water dispensing. PortionedPressing a button dispenses the amount of water corresponding to the time setting. Free-flow Water is dispensed as long as the button is held down, but not longer than the limit time. The limit time is the timer setting for the portioned output. Start-StopDispensing of hot water starts when the button is pressed for the first time and continues until the button is pressed again or the limit time is reached. The limit time is the timer setting for the portioned output. Due to the large output amounts (up to 3 litres) and restricted space on the drip tray, a new output mode has become necessary, particularly for the accounting mode: Free-flow, portioned Water is dispensed as long as the button is held down (free flow), but not more than the programmed quantity (portioned). The button may be released and pressed again any number of times until the programmed quantity is reached. The LED in the button blinks until the programmed quantity has been dispensed. If the button is released and not pressed again within a fixed period of 60 seconds, the dispensing operation is cancelled. However, the full programmed quantity is passed to the accounting system.

2/8 Accounting options 2/8.1 Accounting unit SE

The accounting unit (SE) is mounted beside the power stage. The printed circuit board “serial extension” (SE) has its own software and permits connection of the combiNation F, with the aid of various plug-in cards, to

card readers (MDB and 8-price). Without a “piggyback” card, this board permits implementation of a serial connection to ISB or MC3. The board has its own software which provides the currently available functions “serial interface”, “MDB interface” for card readers of coin changers and “8-price interface”. After a reset (power off and on or first run up), the SE is logged onto the CAN bus as a new node. The software (hardware detection) automatically recognises which of the above options is active and provides other menus at various points within the software (such as the main accounting menu in the customer-service programme or the accounting functions in the customer menu). The serial extension (SE) is not needed for accounting via a coin checker. Software version 3,00,00 or higher is required for operation with the serial extension.

When products are dispensed in waiter self-service mode and debit mode, the dispensed products and the waiter are reported to the ISB or MC3. In the version with table input, the table number is also reported. In credit mode, depending on the settings, the product can be dispensed from the WMF coffee machine: freely if credit is available, with a credit (bar) key (default key No. 61) which can be set as desired, waiter-related by inserting the appropriate waiter key. Waiter self-service (debit) and dispensing on credit can be used in parallel. 2/8.1.1.3 Description of the operating modes Credit mode The waiter creates a credit by ringing up the appropriate product on the cash register. This credit is reported to the SE and the waiter can then dispense the product from a WMF machine The following variants are possible (see the descriptions below): � free credit mode, � credit mode with credit key, � waiter-related credit. Free credit mode No waiter key is needed to dispense the product from the WMF machine. If a credit is available for a product, the ring around the related key on the combiNation lights. If no credit is available and the connection to the cash register is inactive or faulty, no product can be dispensed. Credit mode with credit key The Credit pen is required in order to dispense a product from the WMF machine. Key 61 is defined as the default credit key. Any other waiter key can also be declared as a Credit pen by making the appropriate settings. Only one Credit pen is permitted! If a credit is available for a product, the ring around the related key on the combiNation lights when the valid Credit pen is inserted and the product can be dispensed. If no credit is available and the connection to the cash register is inactive or faulty, no product can be dispensed.

Waiter-related credit mode A waiter key enabled by the cash register is needed for dispensing products from the WMF machine. If a credit is available for the waiter, the ring around the related key on the combiNation lights when the waiter key is inserted and the product can be dispensed. If no credit is available and the connection to the cash register is inactive or faulty, no product can be dispensed. Debit mode In debit mode, each product which is dispensed is stored and, on request (“E”), sent to the cash register. Credit and debit modes may be used in parallel: any existing credit (waiter- or key-related) is first used up, and any further products which are dispensed are stored as debit records. In free bar mode, dispensing on debit is possible only with a waiter key. If the connection to the cash register is inactive or faulty, products can still be dispensed. The data for these products are stored in the machine and, when the connection to the cash register is again available, read in by the cash register (with “E”). Table input If table numbers are used, the table number can be entered on the touch-keys which are displayed after insertion of the waiter key.

There are two possible variants for input of the table number: � without mandatory table input (dispensing for table 0 is possible), � with mandatory table input.



2/8-5

Without mandatory table input When a waiter key is inserted, a table number may be entered. Product dispensing is enabled � If the waiter starts to enter a table number, product dispensing is disabled. � When the input of the table number is terminated with “OK”, the following

is displayed.

Product dispensing is enabled again. � If another waiter is already serving at the table, a cross is

superimposed on the table symbol. With mandatory table input � When an authorised waiter key (in this example, key 2) is inserted, product

dispensing is disabled until a table number has been entered.

� If a table number (in this example, table 1) is entered,

and the input is terminated with “OK”, the following is displayed:

Engineering


2/8-6

Table protection on When table protection is on, no waiter can dispense products for a table at which another waiter is already serving. Once the bill for the table has been paid, the cash register generates a record which causes the SE to release the table again. Any waiter can now dispense products for this table. Table protection off In this case, the combiNation does not automatically protect and release tables on the basis of product dispensing with input of the table number. The SE must be set to this mode if the table-protection function is managed entirely by a cash register. Notes� If the SE receives a deletion record “C000”, all existing credit are deleted.

The debit data remain unchanged! � In OFFLINE mode, products can be dispensed only as long as a credit is

available. If debit mode is not enabled, no further products can be dispensed when the existing credits have been used up.

� Individual credit data can be deleted with the aid of the related cancel records.

Operation without ISB or external MC3 For operation without an accounting system, for example during commissioning of the machine or if the accounting system is faulty, the function “All free” can be set to “Yes” with the manual dispensing key in the selection menu. We strongly recommend that this function be protected by a specially assigned accounting PIN.

The dispensed products are not recorded if “All free” is active.

2/8.2.4 Card reader (KL) 8-price

Eight price lines are available. The card reader assigns each price line to a sales price. Which is then subtracted from the credit on the inserted card (function of the KL). It is also possible to assign products to a common price line and these are then charged at the same price in the card reader (KL). Assignment of a product to the price line “free” permits free dispensing of the product.

The card reader cannot distinguish between price groups defined in the coffee machine. This means that the product statistics in the card reader (KL) will be falsified. 2/8.2.4.1 Product release sequence

Card is inserted in KL and a product key is pressed. Key is signalled to the SE via the CAN. Price line ( PL ) connected to KL on 8-price option (red LED on). KL tests the card. KL connects the Pl with low resistance (green LED on). Timeout 0.2..20s 8-price option detects release at input - CAN message “Release to FB”. FB starts output – sales confirmation "K0 off" for 2s (adjustable). Product output ......... Product is dispensed.

The card reader (KL) needs the product selection on the coffee machine in order to select the price and to decide whether there is sufficient credit on the card. The product price appears on the card-reader display, even if no card is inserted.

SeeSetting card reader Service chapter 4/12.2.6.4 Part 4 - software

2/2 Cleaning


2/9-1

2/9 Cleaning 2/9.1 Automatic cleaning with granulate The cleaning granulate must have the specified solidity. If this is not the case, the granules can break down and cannot be portioned correctly. If there is no cleaning module installed in the machine, the cleaner is inserted through the manual input. The reed switch in the mounting frame and the magnet in the cover of the manual input, combined with the user guidance on the display, permit input of the cleaner to be monitored. 2/9.1.1 Cleaning granulate portioner, complete

The granulate hopper is designed as a chamber-type portioner. The motor is connected to the portioner via gears. The current monitoring circuit detects jamming of the drive motor.

The functions of the individual components are described below. Granulate hopper drive Rated voltage: 24 V DC Operating current: < 0,2 mA

If jamming of the granulate motor is detected, the mechanism travels back and forth up to 50 times in an attempt to free up the hopper. Emergency cleaning: after two unsuccessful attempts to carry out automatic cleaning if the granulate motor is jammed, the system changes over to manual cleaning.

Engineering


2/9-2

2/9.1.2 Granulate light barrier with solenoid

The amount of cleaner is determined by counting the number of granules with the aid of a focussed light barrier. A 24 V solenoid is used to mechanically lock the inlet chute.

Cleaning granulate hopper Clenaing- light barrier Rated voltage: 5 V DC ± 5 % Current consumption: 5 mA

Resistance value 1 k� Timeout pulses 1,2 s between the pulses

2/9.1.3 Soleonid

A 24 V solenoid is used to mechanically lock the inlet chute.

Cleaning granulate hopper - solenoid Rated voltage: 24 V DC Current consumption: < 0,2 mA

Empty signal The interval between two sequential granules is monitored in order to determine when the hopper is empty. The normal interval between two granules is about 500 ms. If no second granule is detected within 1500 ms, the empty condition is reported with a message on the display. Cleaning continues with the number of granules already portioned into the machine. Cleaning continues once only after a time limit of 10 minutes without filling the hopper. At the next cleaning cycle the machine remains idle until the hopper is filled. The “empty” message will only disappear when acknowledged and not for example upon switching the power OFF and ON.

2/10 Chocolate dispenser


2/10-1

2/10 combiNation chocolate dispenser 2/10.1 Chocolate powder hopper (CPH)

The hopper is an auger hopper. The quantity portioned is dispensed on a time control basis. The input nozzle setting on the hopper guarantees even distribution of the powder in the hopper.

2/10.1.1 Empty message

When the hopper is empty, a light barrier controls switching off. If the control unit detects an empty message from the light barrier, this message is stored and a message is displayed on the main machine. All further product preparation is disabled. The operator has to confirm that the hopper has been filled. Confirmation is only accepted by the control unit if the light barrier detects

powder at the same time. Portioning in progress is then continued. If the red LED on the receiver assembly is lit, this indicates that it is connected to the 5 volt supply.

2/10.3 Mixer system

The mixer comprises the hopper, mixer housing, mixer motor with interference filter and mounted rotor. Chocolate products are prepared in flow mode. Hot water is mixed with the chocolate powder in the hopper. The mixture is then beaten in the adjacent mixer to make a creamy product.

Error procedure Mixer monitoring To protect the mixer module, a “check switch” is fitted to act as a monitor. This switches off the motor after one minute if it does not run according to the program sequence. A message is shown in the display. The number of errors occurring is stored in the error memory as information for the service engineer. 2/10.3.1 Mixer motor with interference filter

Because of the gasket, the mixer motor cannot be replaced on its own.

A single-row control panel (maximum 3 buttons) is implemented. The acrylic glass covers can be removed by pressing on one side of the cover and at the same time sliding it towards the edge. When a button is pressed, the product is dispensed (portioned) in accordance with the settings.

2/11 Grounds ejector


2/11-1

2/11 Grounds ejector 2/11.1 Principle of operation

The incoming mixture of rinsing water and grounds (1) passes over a filter (2). As the mixture slides down this filter, some of the rinsing water runs off (3). The remaining grounds (4), which still contain some water, then drop into the grounds container (5), where the remaining water (6) is removed. The rinsing water (3) and the remaining water (6) flow into the drain (7).

The mixture of grounds and rinsing water passes through a further filter, where the water is removed. The grounds fall into a grounds container with a sieve at the bottom. The grounds container can be removed from the machine without dripping and can then be emptied.

Engineering


2/11-2

2/11.2 Upper section with first filter

The first filter is located in the upper section of the grounds ejector. The removal sieve has a bayonet fixing device and can be removed for cleaning. The first filter will operate correctly only if it is not blocked. 2/11.2.1 Rinsing nozzle

The pressure of the incoming water cause the nozzle to rotate so that its jets spray the entire first-filter sieve. The water for this nozzle is connected via a hose from the coffee machine to the nozzle. A solenoid valve in the coffee machine initiates a rinsing operation at regular intervals.

2/11.2.2 Sieve of first filter

The mixture of grounds and water entering the grounds ejector enters the first filter. The water dripping out of the mixture in this filter drips into the overflow tray. The remaining mixture of grounds and water passes through the opening in the first filter and falls into the grounds container.

See"Machine Datas" Software - Part 4

2/11 Grounds ejector


2/11-3

2/11.3 Frame The frame consists of the drip tray and a rear wall. A 1½" flange for the drain connection is screwed to the drip tray. The feet, whose height can be adjusted, are screwed to the rear wall. The unit is designed for use as a free-standing unit. However, the feet can be turned to permit it to be suspended from the counter. 2/11.4 Grounds container

The grounds container is made of plastic (PE). Any water dripping out of the collected grounds can be filtered through the sieve in the container. The sieve is held in the container by a captive nut. It can be removed for cleaning. The base of the container is reinforced with a sheet-metal plate.

2/11.4.1 Container sieve

Engineering


2/11-4

2/11.4.2 Ball valve

The grounds container has a ball valve to prevent dripping when the container is removed for emptying. When the container is removed from the frame of the grounds ejector, the ball closes the drain outlet of the container.

2/11.5 Grounds sensor with height adjustment

A capacitive level sensor is used to prevent the grounds container from overflowing. When the grounds reach a preset level, a "full" signal is generated. An additional sheet-metal plate which moves in front of the sensor when the container is not in the machine permits detection of whether or not the container is in position.

From Mod. 2, this can be mounted on the right if desired.
