Ensure that the empty pad cartridge (4) 4. is inserted and turn the control knob (7) to the position .

Note: You can only turn the control knob (7) to this position if the pad cartridge is inserted (4).

Place two large cups next to each other 5. onto the grate (1).

Press one of the two start buttons (9) or (13) to activate the venting function. During start-up, the number of rinsing cycles required is established electronically. If several rinsing cycles are necessary, each cycle is interrupted after 45 seconds and the ready to brew indicator (11) flashes green again. If necessary, empty the collecting ves-7. Sel and press one of the two start buttons (9) or (B) again.

As soon as the appliance is sufficient-8. ly rinsed, the ready to brew indicator (11) lights up red and the water is heated. Turn the control knob (7) to its home position O.

Do not interrupt the rinsing cycles. Do not remove the water container (5) and do not pull out the power plug; otherwise you will need to restart the start-up process.

Coffee

Coffee soft pads

You can use all conventional coffee soft pads with an outer diameter of 7 cm (coffee quantity of approx. 7 g). Coffee pads with a smaller diameter do not deliver the best coffee. Hard pads offered for espresso machines and pads with additives for cappuccino and such cannot be used.

Never fill damaged pads, loose coffee powder or instant coffee into the pad cartridge (4), as it will clog and block the control knob (7) so that the pad cartridge (4) can no longer be removed. Should this happen nevertheless, please read the instructions in the section "Help with problems".

The quantity of coffee powder in a pad is optimised for one cup of 125ml . The appliance is set at the factory for the following quantities:

Start button (9) approx. 125 ml ideal for 1 pad
Start button (13) approx. 250 ml ideal for 2 pads
You can change the strength of the coffee by varying the filling quantity per cup according to your personal taste and requirements. You will find the detailed instructions for this in the section "Programming mode".

Pad cartridge

Turn the control knob (7) to position and directly back to home position O. The will cause the pad cartridge (4) to be pushed slightly out of the brewing chamber, making it easier to remove. The pad cartridge (4) can be used from both sides. The side marked with is intended for one coffee pad and the side marked with ② is for two coffee pads.

The more carefully you insert the coffee pads, the better the coffee will be. Therefore we recommend that you adhere to the following instructions:

Before inserting the coffee pad, distri-bute the powder in the pad evenly up to the edge.

• Making coffee with one coffee pad: Insert the coffee pad and tap it lightly into place with your finger tips so that a small indentation develops in its centre. Ensure that the paper edge of the coffee pad lies flat in the recess of the pad cartridge (4) without projecting outwards or folding inwards.
• Making coffee with two coffee pads: Press the bottom pad tightly into the recess in the pad cartridge (4), causing its paper edge to fold upwards. Then add the second coffee pad following the procedure described above for one coffee pad.
• When pushing the pad cartridge (4) into the appliance, make sure that the pad does not shift, otherwise the seal will not work reliably.

Brewing

Push the pad cartridge (4) into the bre-1. wing chamber as described above and turn the control knob (7) as far as possible to the right towards

Place one cup in centre position, or 2. two cups next to each other, onto the grate (1).

Wait until the ready to brew indicator (11) lights up green.

Depending on whether you have pre-4.
pared the appliance for one or two
cups, press the start button (9) or
(13). The ready to brew indicator (11) lights up green during brewing.

Pre-brew function: Initially only a small amount of water is pumped through for prebrewing. The brewing cycle proceeds after a short break during which the coffee powder is allowed to soak. This generates an especially intensive aroma.

If you want to cancel the brewing pro-5. cess prematurely, press the start button again.

Turn the control knob (7) back to home 6. position O as soon as the coffee has been let out.

Advice

• Stir the coffee prior to consumption. This will produce coffee of uniform strength throughout the cup.

Remove used coffee pads from the pad - cartridge (4) as soon as possible for hygienic reasons.

Carefully close the pad package to pre-vent loss of aroma.

Fill in fresh tap water every day. Briefly rinse the water container (5) first. Then start a rinsing cycle.

Adjusting the coffee quantity

The automatic coffee pad appliance features a convenient function for programming the required quantity of coffee in

dividually for each start button (9) or (13) independently of each other. This enables you to change the strength of the coffee according to your personal taste and requirements.

Insert the pad as described above and 1. turn the control knob (7) as far as possible to the right towards . Then wait until the ready to brew indicator (11) lights up green.
2. Keep the start button you want to programme, (9) or (13), pressed for 3 to 4 seconds until the ready to brew indicator (11) flashes green. The programming mode is now active during brewing. Observe the cup being filled. When the required quantity is obtained, press the same start button again. The brewing will stop and the brewing time (ON period of the pump) is programmed. Every further brewing with this start button will now be carried out with the programmed brewing time. The quantity of brewed coffee may deviate slightly according to the quality of the coffee powder used.

Notes on the programming mode

The programming mode is activated for approx. 30 seconds after pressing start button , or 60 seconds after pressing start button . If you do not press the relevant start button before the brewing cycle is ended automatically the maximum possible filling quantity will be programmed.

Resetting to the factory-set state

To reset the filling quantity to the factory-set state, proceed as follows:

1. Switch off the appliance.
2. Keep both start buttons (9) and (13) pressed for 3 to 4 seconds until all indicators light up briefly.

Energy-saving functions

Your automatic coffee pad appliance is equipped with several energy-saving functions.

Eco-brewing mode

If you intend to switch off the appliance after one brewing cycle, you can optionally select the eco-brewing mode. This will prevent the appliance from heating up again unnecessarily.

To activate the eco-brewing mode, briefly press both the start button and the ON/OFF button (8) simultaneously. The ready to brew indicator (11) lights up green during brewing as usual, however it will then flash red to indicate that the appliance will be switched off subsequently.

Sleep mode

If the appliance is not used for longer than approx. 5 minutes, the sleep mode is automatically activated. The ready to brew indicator (11) flashes red. To restore the ready to brew mode, press one of the start buttons.

Automatic shut-down

If the appliance is not used for approx. 30 minutes, it will shut down automatically. The power consumption will then be less than 0.5 watts.

The appliance therefore complies with the more stringent demands of European Directive 2005/32/EC concerning the specification of eco-design requirements for electrical household appliances.

More functions

Rinsing process

Clean the appliance if it has not been used for several days. The contents of the heating system will then be replaced by fresh water.

Advice

To save energy, always start the rising process directly after switching the appliance on, i.e. before it heats up.

Fill the water container (5) to the max 1. mark and reinsert it into the appliance. Ensure that the empty pad cartridge (4) 2. is inserted and turn the control knob (7) to position

Place two large cups next to each other 3. onto the grate (1).

Switch on the appliance by pressing 4. the ON/OFF button (8).

Press both start buttons 9 and (13) simultaneously to activate the rinsing process. The ready to brew indicator (11) lights up red during rinsing.

Turn the control knob (7) back to home 6. position O as soon as the coffee as been let out.

Decalcification indicator

Your appliance is equipped with an automatic decalcification indicator (12) which will indicate the need of decalcification by flashing yellow after 4 to 10 weeks. You can then continue to brew coffee with the appliance, but you should not delay due decalcification for too long so as to prevent damage to the appliance.

To protect the appliance from too much calcification, the appliance is set in the factory to run with very hard water. Details of the hardness of your tap water can be obtained from your water works or community administration. Adjust the setting if the hardness of your tap water is less than 21^ . You will then be prompted to decalcify the appliance less often.

Setting the water hardness

The appliance is switched off.1.

1. Keep the start button for two cups (13) pressed for 3 to 4 seconds until the decalcification indicator (12) flashes.

The number of pulses indicates the current setting.

Press the start button 300 (13) repeatedly. The setting is changed with each press of the button.

Once the correct water hardness is set, press the ON/OFF button (8). Only then are your settings saved!

Lightning symbol	Hard-ness	Ca- and Mg- lonen
0 - 7°	H <1,3 mmol/l
>7 - 14°	dH >1,3...2,5 mmol/l
>14 - 21°	dH >2,6...3,8 mmol/l
>21°	dH >3,8 mmol/l

Note: When setting the water hardness, do not wait longer than 10 seconds between pressing the button. Otherwise the appliance will switch off automatically and retain the original value.

You can check the settings at any time by following steps 1 and 2.

Decalcification

Decalcifier

The automatic decalcification programme of your automatic coffee pad appliance is optimised for use with a portion (125 ml) of durgol® swiss espresso®. To decalcify your appliance use this product only in the amount indicated. Only this will guarantee complete decalcification within the short decalcification period and prevention of damage to materials. durgol® swiss espresso® was developed specially for automatic coffee and espresso appliances. The decalcifier is highly effective and guarantees reliable decalcification and therefore long service life of your automatic coffee pad appliance.

You can obtain durgop swiss espresso from select dealers or you can order them directly from petra-electric.

On no account use vinegar or vinegar essence, as the materials in the appliance

could be damaged.

Decalcification with citric acid is too slow. Complete decalcification can therefore not be guaranteed.
Warranty compensation does not exist for damage that occurs due to using an unsuitable decalcifier or non-compliance with the decalcification instructions.
Handle the decalcifying agent carefully to make sure that no damage is caused to furniture or clothing.

Decalcification programme

Your automatic coffee pad appliance has its own automatic decalcification programme. It takes approx. 15 to 20 minutes and is interrupted twice so that you can top up with water.

Note: Once the automatic decalcification programme is started, it cannot be interrupted by pressing a button. This ensures the safety of all users by preventing coffee being brewed as long as the decalcifying solution has not been rinsed out completely. You can pull the power plug if necessary. In this case you should then carry out two rinsing cycles as described in the section "Rinsing process".

Place a collecting vessel with at least 1. 1.2 litres capacity onto the grate (1).

1. Push the empty pad cartridge (4) into the brewing chamber and set the control knob (7) to .

2. Fill a portion (125 mm) of durgof swiss espresso® and then one litre of fresh water into the empty water container (5) and fit it onto the appliance.

3. Switch on the appliance by pressing the ON/OFF button (8).
4. Keep both start buttons (9) and (13) pressed for 3 to 4 seconds until the pump goes into operation. The decalcification indicator (12) will now light up yellow until the decalcification programme is completed.

After approx. 15 minutes the low water 6.

indicator 10) flashes yellow. Empty the collecting vessel and place it back under the coffee outlet (3). Fill the previously rinsed water container (5) with one litre of fresh water. The ready to brew indicator (11) flashes green.

Press any of the two start buttons, 70 (9) or (13) to continue with the first rinsing cycle.

After approx. 2 minutes the low water 8. indicator U (10) flashes yellow. Empty the collecting vessel and place it back under the coffee outlet (3). Fill the water container (5) with one litre of fresh water. The ready to brew indicator U (11) flashes green.

Press any of the two start buttons, 9 (9) or (13) to continue with the second rinsing cycle.

After a further approx. 2 minutes the 10. decalcification programme is completed and the appliance switches off automatically.

After decalcifying the appliance, we recommend to clean the pad cartridge (4) and the coffee outlet (3) together with the filter insert (6) in the dishwasher.

Cleaning and service

Pull the power plug before cleaning the appliance.

Never immerse the appliance in water.

Never leave the appliance to stand for long periods without the water container (5).

Wipe the outside of the appliance carefully with a damp cloth only. Do not use caustic or abrasive cleaning agents; these would damage the surface.

Empty the drip pan (2) regularly to prevent it from overflowing.

All removable parts can be cleaned in the dishwasher except the water container (5).

Clean the water container (5) with warm dishwashing water and rinse with clear water.

Pad cartridge

Check regularly that the centre opening of the pad cartridge (4) is unobstructed. For example, paper towel fibre may clog the opening.

Outlet cassette with filter insert

The quality of the crema is notably reduced by even small deposits in the filter insert (6). This could occur after only 100 cups in the case of calcium residues due to very hard tap water. For this reason, clean the filter insert at regular intervals. The two filters, which are located on top of each other, must not be pressed together.

Pull the outlet cassette downwards and 1. off and remove the filter insert.

Remove any coffee residue with a soft 2. brush and dishwashing water or clean the parts in the dishwasher

If the calcium deposits are not entirely 3. removed from the filter insert (6), place the filter in a decalcifying solution. Then rinse the filter insert (6) again.

After cleaning plug the filter insert (6) 4. back into the outlet cassette.

Reinsert the outlet cassette and press 5. until it locks into place.

Help with problems

The following information will help you with troubleshooting. If this proves unsuccessful, ship the appliance to our central customer service for repairs. Observe the warranty information.

Problem Remedy
The low water indicator U flashes although the water container is filled.	Check if the floating capsule in the water container is freely movable. Remove any foreign bodies or decalcify the water container.
The control knob jams far in advance of the icon.	Check that the pad is properly seated in the pad cartridge. When using 2 pads, the lower pad must be firmly pressed into the recess. Tap the pad lightly so that a small indentation develops in its centre.
The coffee is not strong enough.	The more carefully you insert the pads, the better the coffee will be. You will receive stronger coffee, if you programme a smaller filling quantity.
The cups on the left and right fill unevenly.	Slight filling differences cannot be completely avoided. When the appliance has been in use for some time, the response will improve. Check that the appliance is standing on a level surface.
The filling level sinks gradually.	Always turn the control knob as far to the right towards as possi-ble. Check regularly that the centre opening of the pad cartridge is unob-structed to prevent clogging. Decalcify the appliance early enough.
No coffee is dischar-ged when brewing and the control knob cannot be turned.	If the centre opening of the pad cartridge is clogged, the control knob will block after the brewing and the pad cartridge cannot be removed. Pull the power plug and let the appliance stand for one hour to cool down. Should this not remove the blockage, you can use the emergen-cy opening: For this you need a straightened paper clip. Make sure that the end of the paper clip wire is smooth in order not to damage the appliance. Coffee - which may still be hot - will spray out of the appliance. For this rea-son, hold the wire with a paper towel. •Directly alongside the handle of the pad cartridge is a small opening on both sides of the housing. Insert the wire horizontally into the opening most easily accessible to you and press it slightly inwards. After appro-ximately 3 cm the pressure will suddenly be released and some coffee will escape. The control knob is then no longer blocked. Remove the pad cartridge and clean thoroughly. When using the appliance in the future check before each brewing if the centre opening of the pad cart-ridge is unobstructed and the pads are not damaged.
The quality of the crema is unsatisfactory.	With new appliances, the optimum crema quality will not be obtained until after the appliance has been in use for some time. Clean and decalcify the filter insert at regular intervals. The filters in the filter insert must not be pressed together. If this happens, the insert must be replaced.
The coffee outlet drips over a long period after use.	After brewing always set the control knob back to home position to prevent prolonged dripping.
The appliance switches off when heating up.	The appliance is not allowed to be operated in locations that are higher than 1,500 m above sea level.
The rinsing process does not start.	It is important that both buttons are pressed simultaneously.
The decalcification programme does not start	It is important that both buttons are pressed simultaneously. Try to activate the programme again and release the buttons only after the decalcification indicator comes on permanently and the pump is running.
Water escapes at the handle of the pad cartridge.	Check that the pad is properly seated in the pad cartridge. If the paper edge of the pad projects over the edge of the recess, sealing will be prevented during brewing. Water may escape suddenly even when the pad cartridge is clogged.
There is water under the appliance.	Empty the drip pan in good time. Do not fill the water container higher than the max mark. Never leave the appliance to stand for long periods without the water container.
