2 General description The WMF PROGRMAT GV is designed for automatic dispensing of coffee and hot water. The coffee is dispensed either into a waiting coffee pot or via the flexible hose 19 into a waiting storage urn. Up to 100 litres of coffee can be selected for free-flow dispensing into the storage urn. The automatic brewing function ensures that the 100 litres are not brewed until the 20 litre WMF storage urn can take a complete brewing charge. This ensures that the coffee is not brewed until it is actually required. The coffee machine is fitted with two ground coffee hoppers 1 and can therefore dispense two different types of coffee. If your machine also features a timer 14, it can be switched on and started automatically via the timer. Hot water can be dispensed either in metered quantities or in free-flow. The dispensed coffee is recorded by separate counters 13, each pulse corresponding to one litre. All parts of the WMF PROGRAMAT GV in contact with coffee are cleaned by the automatic cleaning program at the end of the day. The cleaning program is started by pressing cleaning button 12 after inserting the cleaning powder. The storage urns must be cleaned separately. CAPACITY: Up to 120 litres of coffee can be brewed per hour. The capacity is reduced to 100 litres of coffee per hour if hot water is drawn directly from the WMF PROGRAMAT GV (approx. 20 litres per hour). This hourly capacity must be rated very much higher than that of semi-automatic coffee machines, since it does not depend on the motivation and skill of the operating personnel. Together with an initial supply of 20 litres per storage urn, this high brewing capacity allows peak demand levels to be handled effortlessly.

3 Warnings Complete machine safety is an integral WMF product 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 with a background Please also note the �Safety Instructions� on page 46. For your own safety, please observe the following instructions at all times :
! Connection of the machine and starting up for the first time must only be carried out by WMF customer service technicians
! All maintenance and repair work must only be carried out by WMF customer service technicians or authorised persons. Only original parts should be used.
! In no circumstances should any alteration be made to the built-in safety devices.
! Caution! Danger of scalding! Note the danger of scalding around the hot water spout 8 and coffee dispensing heads 15 and 19.
! Caution! Danger of burning! Do not touch the hotplates 11 and coffee dispensing head for pots 15 when the machine is switched on. Serious burns may result.
! Caution! Risk of crushed fingers! Never reach into the ground coffee hoppers 1 and brewing unit 30 when the machine is switched on. Crushed fingers may result.
! Caution! Danger to health! Cleaning solution flows from the flexible hose 19 during the cleaning program and must be drained off safety. Connect the flexible hose 19 to the cleaning adapter 16 on the WMF PROGRAMAT GV. Note the safety precautions specified on the package when handling the cleaning solution. Ensure that there is no pot under the coffee dispensing head 15 during the cleaning program.
46
4 Safety instructions General 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 disconnected from the socket.
2. The built-in type-tested safety devices prevent the pressure and temperature inside the water boiler rising inadmissibly. If the relief valve is ever tripped, the machine must be switched off immediately and disconnect from the power supply. Call the WMF customer service and do not switch the machine on again until the fault has been remedied.
3. The housing of the WMF PROGRAMAT GV and storage urn must not be hosed down or cleaned with a steam jet. The surface should be wiped with a damp cloth or with one of the products from the WMF care range.
Machine shutdown 1. If the machine is to be shut down for an extended period of time, a general cleaning should be
carried out first. Drain the machine to prevent frost damage, if is to shut down for an extended period of time. The WMF customer service must be called in 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.
Hot water boiler data - see rating plate The hot water boiler complies with the German regulation governing steam boilers (DampfkV), as well as the implementing regulations pursuant to TRD 801 (Technical Rules for Steam Boilers, issued by the Central Association of Technical Control Boards (VdTÜV) on behalf of the German Steam Boiler Committee). The hot water boiler is subject to neither notification nor licensing. Each hot water boiler is subjected to hydrostatic tests with 4.2 bar excess pressure 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.
47
Preventive measures against consequential machine damage ! Any technical devices, 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 9° (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
conditions, 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.

+1h[ ][ ][ ][ ]
The machine is switched on (ON) when button is AM 14:57 pressed twice, but the timer is deactivated at the same time. The machine can now be switched on and off via the ON / OFF switch 3.
7.2 Brewing coffee
Caution! Note the danger of scalding around the dispensing head for coffee pots 15 and the flexible coffee hose 19 during the brewing process.
The amount of coffee to be brewed must always be selected first: # Pot of coffee or # Large quantity via flexible coffee hose 19. The brewing process is started by pressing one of the buttons (NORMAL) or (SPECIAL). (NORMAL) refers to the left-hand ground coffee hopper, while (SPECIAL) refers to the right-hand hopper.
Fig. 1
This means that two different types of coffee can now be brewed automatically, e.g. normal coffee and decaffeinated coffee.
Normally; your WMF PROGRAMAT GV is programmed for one type of coffee and the ground coffee is always drawn from both ground coffee hoppers 1 alternately. Your coffee machine can be programmed for two types of coffee by the WMF customer service on request.
52
When pressed, button 9 lights up until the set quantity has been dispensed. In order to cancel a selection prematurely, turn selector 5 to �0�. However, the brewing process in progress will be completes first.
7.2.1 Dispensing coffee via the free-flow spout
Selector 5 must be set to (free-flow spout) so that coffee can dispensed via the flexible hose 19 into a waiting storage urn.
Fig. 2
Example: Free-flow coffee has been programmed and the selector set to 5 litres.
The amount of coffee to be brewed is set on a scale extending up to 100 litres. The brewing process is started via the buttons (NORMAL) and (SPECIAL). The selected button 9 lights up until the set amount of coffee has been brewed.
Fig. 3
Example: NORMAL lights up until 20 litres have been brewed.
The small LED between the buttons NORMAL and SPECIAL always lights up and indicates that only coffee is being dispensed via the flexible hose 19 (See Chapter Via the free-flow spout on page 55).
The WMF PROGRAMAT GV also includes an automatic brewing function in combination with the WMF storage urns (type 03.6620.0001 and 03.6620.1001). The control line 20 is plugged into the storage urn and the WMF PROGRAMAT GV for this purpose:
Fig. 4
If the quantity selected exceeds the capacity of the storage urn (20 litres), the machine automatically continues to brew coffee until the programmed quantity has been brewed. The signal for renewed brewing is output to the coffee machine whenever the level in the storage urn drops below 15 litres.
20
53
If a storage urn is used without automatic brewing function, the machine must be connected to the dummy jack 33.1259.7000 or the dummy plug 33.1253.5000 must be fitted to the control line 20 which remains plugged into the WMF PROGRAMAT GV (Fig. 5). When working with different storage urns, with and without automatic brewing function, the dummy socket / dummy plug must always be connected to the side on which the urn without automatic brewing function 20 is located.
Fig. 5
Note! If the quantity set exceeds the capacity of the storage urn, it may overflow if there is no automatic brewing function and you may be scalded.
The flexible hose 19 on your WMF PROGRAMAT GV can move in all directions so that you can fill the storage urn in any position.
Variations:
Fig. 6
The flexible hose 19 is connected to the storage urn via a coupling (Fig. 7). A safety valve is fitted in the connector on the flexible hose 19, thus ensuring that coffee cannot leak out when the hose is not plugged in.
Fig. 7
The following points must be noted in order to start brewing coffee: 1. The flexible hose 19 must be plugged into the coupling
(see Fig. 7) on the storage urn. 2. The control line 20 must be plugged into the storage
urn for automatic brewing. If the function is to be bypassed, the dummy socket must be fitted in the machine and the dummy plug on the control line (see Fig. 5).
3. The storage urn must be plugged into the socket 7 of the WMF PROGRAMAT GV or another 230 V socket outlet and must be switched on via the ON / OFF switch 23.
Dummy plug 33.1253.5000Dummy jack

54
The automatic brewing function ensures that there is a constant supply of coffee available to meet the continuous demand. Selector 5 is set to �0� if a selection is to be cancelled prematurely. The brewing process in progress is completed first, however.
Press the ON / OFF switch 3 to interrupt the dispensing of coffee immediately.
7.2.2 Dispensing coffee into pots
Coffee can also be dispensed directly into glass or thermos pots positioned under the dispensing head of the WMF PROGRAMAT GV . the amount of coffee to be brewed must be selected first. Selector 5 must be turned to for this purpose:
Fig. 8
Dispensing is started by pressing the buttons (NORMAL) or (SPECIAL). If (NORMAL) is pressed, coffee is taken from the left-hand ground coffee hopper 1; if (SPECIAL) is pressed, it is taken from the right-hand hopper. The selected button 9 lights up while coffee is being dispensed. The button must be pressed again for each subsequent pot of coffee to be dispensed. If only one type of coffee is used (normal situation), it is alternately metered from both ground coffee hoppers.
Fig. 9
The amount of coffee to be brewed for the pots is programmed as required (between 1 and 2.5 litres) by the WMF customer service. The WMF PROGRAMAT GV includes two hotplates 11 specially for serving coffee from pots. These hotplates can be switched on individually as required.
Fig. 10
Caution! The hotplates 11 are very hot when switched on and may burn you!

7.3 Dispensing hot water
Caution! Note the danger of scalding near the hot water spout 8.
7.3.1 Via the hot water spout
Hot water can be dispensed for making tea, hot chocolate, a stiff grog, etc. The amount to be dispensed for your particular purposes will be programmed by the WMF customer service. The set quantity (0.1 to 1.8 litres) is accurately dispensed via the hot water spout 8 when the hot water dispensing button 6 is pressed. The dispensing will be interrupt when the hot water button 6 is pressed a second time before the dispensing is finished.
Fig. 11
7.3.2 Via the free-flow spout
Note: If hot water is to be dispensed via the flexible hose 19 after making coffee, the cleaning program must be started first in order to remove any remaining coffee.
The option is set by the WMF customer service engineer. You can then choose whether to dispense coffee or hot water via the swivelling spout 19. The changeover is effected as follows:
1. Standard setting � coffee
Fig. 12

11 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.
12 Warranty claims WMF shall give a warranty for legitimate defects as to quality as follows: Any products 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), 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). The warranty period is extended to cover a period of 24 months after the risk was passed, if the buyer, at the time of concluding the sales contract, also enters into a service agreement for a regular maintenance of the percolator purchased. The extension of the warranty period is only effective, if the service agreement concluded has a minimum term of two years. 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.

We do not give a warranty: - 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 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 Product Liability Act, in cases of willful 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. A reversal of the burden of proof to the disadvantage of the buyer is not implied by the above regulations.
