MACHINE INSTALLATION

Preparation for installation

Make sure the machine is placed on a water-resistant surface in case of water spillage or leakage.
Place the machine on an even and stable surface. You can regulate the height by adjusting the feet of the machine.
Never place the machine on hot surfaces.

Electrical connection

Make sure the local main supply voltage corresponds to the information given on the type plate under the espresso machine.
Only use the connection cable supplied.
Plug the machine into a grounded socket only
Do not leave it unattended.
Make sure that you use the correct power plug for your country.
Do not roll or bend the power cord.
Do not use an extension cord/ do not use a multiple socket.

FIRST USE

Read the instruction manual carefully before operating the machine.

Prior to starting the machine, check if:

the machine is switched off
(Power switch on the back of the machine is set to to “0”.)
the power cord is disconnected.
the drip tray is inserted accurately.

Now you can begin to operate your machine:

Attach connecting hoses to the top back of the machine.
Put the other end of the connecting hoses throug the corresponding holes of the water tank lid.

Attach the silicone hose on the inside of the water tank lid.

#1 and #2: Connecting hoses
#3: Silicone hose

Important!
Make sure to attach the silicone hoses according to the marking on the lid of the water tank and the back of the machine!If the connecting hoses are attached incorrectly, the machine will not draw water.

Fill the water tank with fresh water, preferably deficient in lime.
Place the lid with the silicone hoses on the water tank.
Insert the plug properly into the socket and turn the on/off switch on the back of the machine to the right when viewed from the front. Now the machine is switched on.

Important!
For the initial set-up the boiler has to be filled by moving the brewing lever upwards.

Fill Mode
When using the machine for the first time, it will be in fill mode, with “FIL” displayed on the PID. Place a small container (e.g. a milk pitcher) under the brew group. Move the brew lever up and the pump will start to fill the boiler. Rinse the machine for at least 30 seconds until water comes out of the brew group. When you move the brew lever down, the indication “FIL” in the display should have disappeared.
The machine will now heat up. The PID display shows the boiler temperature or UP. The pump pressure gauge may deflect during the heating phase. Please note that this deflection is not relevant to the process and can be disregarded. If UP appears in the display during heating, continue reading under chapter “6.1”.

Before preparing the first coffee, please clean the machine by extracting about 2-3 water tank fillings from the brew group and the hot water wand. See also chapter 6.4 Dispensing of hot water.

Important!
The PID-control assists the machine in keeping a constant boiler temperature. This means that the machine constantly regulates the temperature and the small dot in the PID display flashes for one heating interval at a time. The boiler temperature is indicated on the PID- display.
Make sure that there is always enough water in the glass water tank during operation.
If there is no water in the tank, the machine draws air and a loud pumping noise can be heard. If the pump does not draw water after filling, switch off the machine and let it cool down before switching it on again.

USE OF THE MACHINE

Preparation of the machine

The switched off machine is to be placed into operation as follows:

Make sure that there is sufficient water in the glass water tank. Refill water if necessary.
Turn on the machine (the switch is on the back of the machine and lights up orange when switched on).
If the boiler temperature is below 40°C when the machine is switched on, the display will show “UP” and the machine will start in Fast Heat Up mode.
The heating period depends on the ambient temperature and is approx. 10 minutes. The indicator of the pump pressure gauge may move slightly during the heating-up phase.

The Puristika is heated up as soon as the desired preset temperature appears on the PID display or the display shows FLU. While ‘FLU’ is shown on the display, the user should perform a flush until ‘rdY/Go’ is shown on the display. To do this, keep the portafilter clamped and place a tall cup under the portafilter spout.
When the message ‘rdY/Go’ appears, the machine is ready to brew the first cup of coffee.
If the user does not perform a flush within the one-minute period (step 4), the display will show the message ‘FLU’ alternating with the current temperature. In this case, the flush should be started and stopped based on visual characteristics.

If the user does not perform a flush, the boiler temperature will cool down to the desired brewing temperature after a short time.

	It is recommended to leave the portafilter in the brew group, keeping it warm for optimum coffee extraction temperature.
	As soon as you start a withdrawal while the machine is heating up (‘UP’ is shown in the display), the Fast Heat Up is interrupted; in this case, the brewing group needs a little longer to reach the desired temperature. If you do not want to use the Fast Heat Up, you can set the function to ‘off’ under the FH entry by calling up the menu (hold down both buttons on the display).

Manual adjustment of the brewing pressure
You can individually adjust and change the brewing pressure by turning the expansion valve. The brewing pressure is factory set to 9 – 10 bar.

To adjust the brewing pressure, proceed as follows:

Place the portafilter with the blind filter (filter without holes) into the brew group.
Operate the brew lever and read the brewing pressure on the pump pressure gauge.

Set the brewing pressure to the desired value during brewing by turning the expansion valve.
Brewing pressure:

You can reduce the brewing pressure by turning the screw anti-clockwise and increase it by turning it clockwise.

Only adjust the brewing pressure with the blind filter.
Caution, the handle can be hot with time!
Frequent adjustment of the brewing pressure has a negative effect on the coffee and leads to faster wear of the O-ring, the expansion valve.

You can see the set brewing pressure on the pump gauge.
Move the brew lever back into the lower position to stop brewing. Unclamp the portafilter and replace the blind filter with the regular coffee filter.
Now the machine is ready for operation again.

	In order to avoid premature wear on the valve, the expansion valve should only be readjusted occasionally and should not be overtightened. Since the expansion valve is not a wear-tricomponent, strong tightening and frequent adjustments can be damaging for the internal rubber plug and spring.
	Changing the brewing pressure is recommended in the following cases: The brewing pressure has changed slightly and needs to be adjusted A lighter/darker coffee roast requires an adjustment of the brewing pressure The coffee grinder in use cannot grind any finer and the pressure is not ideal

PID-Temperature Control
The PID-Temperature control allows you to adjust the current temperature of the coffee boiler. This means that you can extract your espresso at a variety of temperatures. The PID-display indicates the boiler temperature.

Temperature (here 93°C)

The dot indicates the heating interval:–

Permanent dot = the machine is heating
Flashing dot = the temperature regulates the set temperature.

PID-menu

PID menu sequence	Selection	Mode	Action	Change of setting
				Temperature value is increased Temperature value is reduced Programming in steps of 30. Adjustable time between 0 and 600 min. Programming in steps of 10 between 0 and 200.
				Selection between C for Celsius and F for Fahrenheit Activate (on) or deactivate (oFF) the Fast Heat Up

When the desired value has been reached, wait a short time and you will exit the menu automatically.

Programming the temperature via the PID-display
During normal use, the temperature is indicated on the display. The coffee temperature control is preprogrammed to 93°C.

Switch the machine on in order to activate the boiler. The temperature of the boiler is of no importance for programming. The heater is inactive during programming.
Press + and – at the same time until ‘t1’ appears on the display,
Press + in order to progress to the submenu of ‘t1’ and to change the temperature value. The nominal temperature value is displayed.
Quickly press– to decrease+ to increase the nominal temperature value.
Please wait a short while after having set the nominal temperature value; ‘t1’ will be displayed. The set temperature is accepted and you exit the menu.

Programming the ECO-Mode
The ECO-Mode gives you the option to set a timer that will automatically switch off your machine. After the last brewing process, the machine will start the timer. The timer will be running in the background and is not visible. When the timer ends the machine will automatically turn off. To reactivate the machine, either press a PID key or switch the machine off and on again.

1. Switch on the machine.
2. Press + and – at the same time and “t1” appears on the display.

5. After a short period the setting will be adapted and saved.

Programming the group cleaning mode “CLn”
With the Puristika you have the option to program a reminder for next the group cleaning at the PID display.
The machine is set to 0 at the time of delivery, meaning no reminder is programmed yet.

Please take the following steps to program the cleaning reminder:

Press + and – at the same time and “t1” will appear on the display. Press the – button until you reach “CLn”. Press + to enter the CLn menu.Now you can carry out the programming in steps of 10 (0-200) by pressing + and –.In order to leave the programming mode, wait until “CLn” appears andthen press the – button.For example, if you have programmed 90, you will be prompted with a“CLn” on the display to clean the brew group after 90 brew cycles. Clean the brew group (see 7.2 “Brew group cleaning”).
	We recommend cleaning the brew group after about 90 to 140 brew cycles. Only a brew over 15 seconds counted as a brew cycle.

If you operate the brew lever after “CLn” appears on the display, a counter on the display counts from 10 to 1 per brew lever operation. The temperature value is displayed and the programmed reminder value is active again

Programming the Temperature Mode “o”
You can also set whether the boiler temperature values of “t1” should be displayed in °C or °F.
To adjust this setting, proceed as follows:

1. Press + and – at the same time and “t1” will appear on the display.
2. Press the button – twice. After “t1”, and “St”, “o” appears on the display. Press + to enter the menu.
3. Now you can choose between C for Celsius and F for Fahrenheit by pressing –. This will set.
4. Wait a short time and you will exit the menu automatically.

Programming the Fast Heat Up Mode
Your machine is equipped with a fast heat-up function (Fast Heat UP), which ensures that the desired brewing temperature is reached within a few minutes. This function can be deactivated in the menu.

6. Press + and – at the same time and “t1” will appear on the display.
7. Use the “–” key to navigate through the menu. As soon as “FH” appears on the display, confirm with the “+” button.
8. Now you can choose between “on” for activation and “oFF” for deactivation by pressing the “+” button.
Wait a short time and you will automatically exit the menu.

Preparing coffee
Use the portafilter with the corresponding filter (1 cup) for the preparation of one cup and use the big filter (2 cups) to prepare two cups. Make sure that the filter is firmly locked into the portafilter.
Fill the grounded coffee with the respective grind for espresso into the filter (The marking inside the filter basket can help you find the correct amount of coffee.).
Only freshly grounded coffee allows an optimal coffee result. Therefore, use a professional coffee grinder. In our product range you will find several professional and compact coffee grinders.
Compress the ground coffee with a tamper. A tamping pressure of approx. 20 kg is recommended. Thus, the ground coffee is evenly compacted. Clamp the portafilter firmly into the brew group.
Place the cup under the spout of the portafilter (for the preparation of 2 cups, put 1 cup under each spout).
Now activate the brew lever to start the brewing process. The PID-display indicates the brewing time in seconds. In general, the brewing time should be around 23 to 25 seconds.
The volume for a single espresso is circa 25 to 30 ml. Place the brew lever back into the original position once the desired volume has been reached. The remaining pressure/water will be discharged into the drip tray through the lower part of the infusion cylinder.

Important
Only with the correct / fine grinding degree and the correct pressing with the tamper the pump pressure gauge rise.

If the group lever is not moved into the lower position properly, hot water and grounds disposal will squirt out of the brew group while taking out the portafilter. This may cause injuries.

CL ANING AND MAINTENANCE

A regular and accurate care is very important for the performance, the longevity and the safety of your machine.

Caution!
Always switch off the machine (power switch in lower position), disconnect the power cord and let the machine cool down to room temperature before cleaning.

General cleaning

Daily cleaning:
Portafilter, filters, glass water tank, drip tray, drip plate of the drip tray, measuring-spoon and tamper require daily cleaning. Clean with warm water and/or a food safe detergent. Do not put them into the dish washer.

Clean the shower screen and the group gasket in the lower part of the group and remove visible dirt without disassembling the parts.

Cleaning as necessary:
Clean the body when the machine is switched off and cold.
Depending on usage, please refresh the boiler water every 1 – 2 weeks. Please extract approx. 0.8 l of hot water from the brew group.

Use a soft, damp cloth for cleaning. Never use abrasive or chloric detergents!

Empty the water drip tray regularly and do not wait until it is full.

Brew group cleaning
An ECM brew group cleaner is available at your specialised dealer. With this detergent, you can clean and degrease the group very easily. For cleaning the brew group, please use the blind filter included upon delivery. When using our group cleaning tablets, we suggest cleaning after approx. 90 – 140 cups.

Follow the instructions as noted below:

Heat up the machine until the optimum operating temperature has been reached.
Place the blind filter into the portafilter.
Put approx. 3 – 5g of the group cleaning powder into the blind filter.

Clamp the portafilter into the brew group.
Operate the group lever. The blind filter will be filled with water.
Let the detergent react, moving the group lever into the middle position, approx. 45°. (Do not move it into the lower position.)

Move the lever into the lower position after approx. 20 seconds. This way, the grease and oil can be discharged by the infusion cylinder.
Repeat steps 5-7 up to 10 times, until only clear water is discharged by the infusion cylinder.
Rinse the portafilter and the blind filter with fresh water. Then replace it.

Operate the group lever for approx. one minute. Then move it back into the lower position.
Remove the portafilter and repeat point 10. After this, the brew group is ready for use.
Place the filter for 1 or 2 cups into the portafilter.

	Caution! Beware of hot sprayings while cleaning the group.
	In case you programmed the cleaning mode, the “CLn” will disappear on the display after having operated the brew group lever 10 times. The counter will then restart until the next cleaning advice. How to program the group cleaning mode see 6.3.3
	If the brew group is cleaned too often with cleaner, it may start squeaking. Moreover, it may be that you will degrease all the moving parts and they will wear out quickly. Please make sure the brew group is cleaned from time to time without cleaner

Maintenance

Caution!
Make sure that the machine is disconnected from the mains during maintenance and when replacing individual parts.

(If you have any questions, please contact your specialised dealer.)
