Preparing and using for the first time

Setting up the machine
- When setting up your E4, please note the following:
- Place the E4 on a horizontal surface that is not sensitive to water.
- Choose a spot for your E4 which protects the machine against overheating. Ensure that the ventilation slots are not covered.
Filling the bean container
- The bean container has an aroma preservation cover. This will ensure that your coffee beans retain their aroma for longer.
- Coffee beans which have been treated with additives (e.g. sugar),
  ground coffee or freeze-dried coffee will damage the grinder.
- Only use roasted, untreated coffee beans to fill the bean container.
- Remove the aroma preservation cover.
- Remove any dirt or foreign objects from inside the bean container.
- Fill the bean container with coffee beans and close the aroma preservation cover.
Determining the water hardness
- When you use the machine for the first time, you must set the water hardness. If you do not know the hardness of your water, you can find this out first. Use the Equator® test strips supplied with the machine.
- Hold the test strip under flowing water for one second. Shake off the water.
- Wait for about 1 minute.
- You will then be able to read the degree of water hardness from the discoloration of the Equator® test strip and the description on the packaging.
First-time use
- If the machine is operated with a defective mains cable, there is a danger of potentially fatal electric shock.
- Never use a machine which is damaged or has a defective mains cable.
  Milk, sparkling mineral water or other liquids can damage the water tank or the machine.
- Only fill the water tank with fresh, cold water. Precondition: The bean container has been filled.
- For machines with a plug-in mains cable: Connect the mains cable to the machine.
- Insert the mains plug into a power socket.
- Press the On/Off button Q.
- The number of symbols that are brightly lit up indicates the water hardness level: 1–7 °dH (s), 8–15 °dH (ss), 16–23 °dH (sss) and 24–30 °dH (sss £).
- If you do not know the hardness of your water, you can find this out first (see chapter 3 ‘Preparing and using for the first time – Determining the water hardness’).
- Press the i/o button to set the water hardness.
- Press the s button to confirm the setting. The ! and u symbols appear.
- Remove the water tank and rinse it with cold water.
- Fit the filter cartridge extension supplied on top of the CLARIS Smart filter cartridge.
- Insert the filter cartridge with its extension into the water tank.
- Turn the filter cartridge clockwise until it audibly clicks into place.
- Fill the water tank with fresh, cold water and reinsert the tank.
- The machine automatically detects that you have just inserted the filter cartridge. The sss £ symbols flash from right to left to show that you need to open the switch for hot water preparation.
Preparing and using for the first time
- Place a receptacle under the hot-water spout.
- Turn the switch to the x position.
  The filter is rinsed. Water flows out of the hot-water spout. Rinsing of the filter stops automatically. The sss £ symbols flash from left to right.

- Place a receptacle under the coffee spout. The sss £ symbols flash while the E4 is heating up. The machine is rinsed. Water flows out of the coffee spout. The rinse stops automatically. Your E4 is ready for use.
Connecting the machine to the WiFi network (optionally)
- Your E4 can be connected with your JURA app (J.O.E.®). Precondition: J.O.E.® is installed on your mobile end device. The optionally available JURA WiFi Connect is inserted into the service socket of your E4. For more information on setting up the WiFi Connect go to jura.com/wifi or scan the QR code.

Preparation

Basic information about preparing drinks:
- All products can also be prepared using the JURA app (J.O.E.®).
- With the JURA app (J.O.E.®) you can make two additional specialty coffees: the café Barista and the lunge Barista.
- If no action is performed on the E4 for 5 minutes, the symbol goes dark. However, the E4 remains ready for use. Coffee tastes best served hot. A cold porcelain cup cools the beverage – and impairs the taste. We therefore recommend prewarming the cups. You can purchase a JURA cup warmer from your specialized dealer.
Espresso and coffee
- Example: Coffee
- Place a cup under the coffee spout.
- Press the o button.
  The preset amount of water for coffee flows into the cup.
Two espresso and two coffees
- Example: Two espressi
- Place a cup under the coffee spout.
- Press the i button 2x.
- Two brewing operations take place one after the other. Change the cup before the second brewing operation.
- To prepare two coffees, press the o button 2x. The preset amount of water for espresso flows into the cup.
Hot water
- Place a cup under the hot-water spout.
- Turn the switch to the x position. Hot water flows into the cup.
- Turn the switch to position ° to stop the preparation of hot water.
Café Barista and lunge Barista (optionally with J.O.E.®)
- The JURA app (J.O.E.®) offers two additional products for you to choose from: café Barista and lunge Barista. Example: Lunge Barista
- Place a cup under the hot-water spout.
- In the JURA app (J.O.E.®), tap the product ‘Lunge Barista’.
- Follow the instructions in the app.
Permanently setting the amount of water for the cup size
- It is easy to make permanent settings for the amount of water for all specialty coffees according to the cup size. Adjust the amount once as shown in the following example. Every time you prepare a drink in the future, this amount of water will be dispensed.
  Example: Proceed as follows to permanently set the amount of water for one coffee.
- Place a cup under the coffee spout.
- Press the o button for about 2 seconds. The coffee flows into the cup.
- Press any button as soon as there is sufficient coffee in the cup.
  Preparation stops. The set amount of water for one coffee is permanently stored.
- You can alter this setting at any time by repeating the above procedure.
Adjusting the grinder
- You can adjust the grinder to suit the degree of roast of your coffee. If you adjust the consistency of grind when the grinder is not operating, the grinder adjustment switch could be damaged.
- Only adjust the consistency of grind when the grinder is running.
- The consistency of grind is correct if the coffee flows regularly from the coffee spout. In addition a fine, thick crema forms.
  Grinder adjustment switch
- 1: Fine consistency of grind setting
- 2: Coarse consistency of grind setting
  Example: Proceed as follows to change the consistency of grind during the preparation of an espresso.
- Place a cup under the coffee spout.
- Open the cover of the filler funnel for ground coffee.
- Press the i button.
- Turn the grinder adjustment switch to the desired position while the grinder is running.
  The preset amount of water flows into the cup.

Ground coffee
- You can choose to use a second coffee variety, for example decaffeinated coffee, with the filter funnel for ground coffee. Basic information about ground coffee:
- Never add more than two level measuring spoons of ground coffee.
- Use ground coffee which is not ground too finely. Very fine coffee can block up the system so that the coffee only comes out in drips.
- If you did not fill the machine with enough ground coffee, the £ symbol flashes and the E4 stops the operation.
- The desired specialty coffee must be prepared within approximately one minute after filling with the ground coffee. Otherwise the E4 stops the operation and is once more ready for use.
  All specialty coffees with ground coffee are always prepared following the same model.
- Example: Proceed as follows to prepare an espresso using ground coffee.
- Place an espresso cup under the coffee spout.
- Press the s button several times until the £ symbol lights up brightly.
- Open the powder chute cover.
- Place one level measuring spoon of ground coffee into the filler funnel.
