4. Open the compartment and remove the hot water spout. Connect the tube to the machine's steam connector.
   
5. Place a container with a minimum capacity of 1 litre under the coffee outlet and hot water spout (as shown in the figure).
   
6. Press to confirm. The descaling solution passes alternately through the coffee outlet, the hot water spout and the drip tray.
   
7. Empty the used capsule container and the drip tray and rinse under tap water.
   
8. Fill the tank with fresh drinking water up to the MAX level. Repeat step 5 again.
   
9. Press to confirm again. The rinse cycle continues through the coffee outlet, the hot water spout and the drip tray until the water tank is empty.
   
10. Once the rinsing system has finished, the machine turns itself off.
    
11. Remove, rince and place the hot water spout in the relative compartment. Empty the drip tray and the used capsule container. Fill the tank with fresh drinking water.
    

Setting water hardness

The descaling cycle is requested after a set period of operation, which depends on the water hardness. The appliance is factory set for a hardness value of 5. The appliance can also be programmed according to the actual hardness of the mains water in the various regions, thereby running the descaling process less frequently.

1. Enter the Menu, browse the options and select WATER HARDNESS. You will be guided throughout the whole process. Follow machine display instructions.
   
2. Unpack the "TOTAL HARDNESS TEST" strip. Fully immerse the strip in a glass of water for approximately one second.
   
3. Remove the strip from the water and shake it gently. After about a minute, 1, 2, 3, 4 or 5 red squares form, according to the water hardness.
   
4. Set the value accordingly.
   

Maintenance

Checking pressure and leaks

Read the general safety notes.

1. Open the machine as indicated in section General disassembly, on the 2-3-4 points.
   
2. Insert the blue "false capsule" instrument (2) supplied into the extraction chamber (1). Make sure it is well positioned and secured.
   
3. Insert the blue pressure gauge locking support (4) and push it downwards. Once the support is fully inserted, lower the lever.
   
4. Connect the pressure gauge to the "false capsule" instrument as shown in the figure.
   Place an empty container under the pressure gauge drain tube (3).
   
5. Open the pressure gauge valve (5).
   
6. Turn on the machine.
   
7. Press the Espresso button and allow water to fill the container for 10 seconds.
   
8. After 10 seconds, close the valve (5).
   The pressure starts to rise and stabilise at 17.5 +/- 1.5 bar (pump pressure control).
   

Keep an eye on the pressure gauge. If the pressure exceeds 23 bar, the machine must be turned off and the pressure lowered using the pressure valve.

Check for leaks in all hydraulic connections.

The pump should not run for more than 50 seconds without water flow.

If there is any micro leakage, the indicator of the manometer will drop down very fast under 10 bars.

After checking, the residual pressure must be released by opening the pressure valve!

Measuring coffee temperature

1. Switch the machine ON.
   
2. Place a measuring cup under the coffee outlet. Lift up the lever and insert the capsule.
   
3. Close the lever and press the Espresso button. Wait until there is at least 20 ml of coffee in the measuring cup.
   
4. Measure the temperature of the flow at a distance of about 2-10 mm from the outlet (as shown in the figure).
   

Coffee temperature should be 86°C ± 3°C (187°F ± 5.4°F)

Measuring milk temperature

1. Switch the machine ON.
   
2. Fill the milk container with about 200 ml of low fat milk at a temperature of 5°C ± 2°C. Place the lid and connect the milk container to the machine with the foam knob regulator in MAX position. Place a 250 ml graduated glass beaker under the milk outlet tube.
   
3. Use a digital thermometer equipped with a "K" type thermocouple sensor and place it under the milk outlet tube.
   
4. Press either Cappuccino or Latte Macchiato button and deliver around 100 ml of milk during the brewing measure the milk temperature.
   

Check the following aspects:
Brewing aspect: without splashing
Temperature milk: 57 - 67°C
Foam quantity: on the transparent container the final result must be 1/2 milk and 1/2 foam.

Safety test

After any repair and /or replacement of any part, in any case whenever the coffee maker is split apart, once re-assembled, is necessary to perform the safety test, according to the EN/IEC 60335-1.

The test to perform, using a proper test device (e.g. model TG uni 1 produced by GMW Gossen METRAWATT, or an equivalent one), are the following.

• Protective Earth continuity test( ohmic resistance must be less than 0,1 Ohm);
• Protective insulation test (supply 500 DC, ohmic resistance must be over than 2MOhm).

Procedure:
The machine has not external metal parts, you will have to connect the probe of the test device through the dedicated hole on the bottom of the machine (see picture) in order to assure a contact with the lower metallic part of the steamer. Then plug the machine on the dedicated socket on the test device.

General safety notes

To prevent possible injury and damage, read and follow the instructions completely.

To prevent the risk of a fatal electric shock and fire

• Connect the appliance to suitable earthed mains connections only. Make sure the power supply is the same as that indicated on the rating plate. The use of incorrect connections will void the warranty.
• In the event that an extension cord is required, use only one earthed cord with a conductor cross section of at least 1.5 mm².
• Do not move the cord close to sharp edges. Block it or allow it to hang. Keep the cord away from sources of heat and humidity.
• Do not operate the appliance if the cord is damaged.
• To prevent hazardous damage, do not place the appliance on or next to hot surfaces such as radiators, electric or gas stoves, naked flames or similar. Place it only on stable and level surfaces. The surface must be resistant to heat and liquids, such as water, coffee, descaling products or similar.
• To prevent damage, unplug the appliance holding the plug. Never pull the cord. Never touch the plug with wet hands.

To prevent damage during operation

• The appliance has been designed for domestic use only. If it is not used in accordance with the instructions, the manufacturer assumes no responsibility and is authorised not to apply the warranty conditions.
• Keep the appliance out of reach of children.
• To prevent scalding, keep the lever closed during operation and do not put your finger under the coffee or milk outlet.
• To prevent injury, do not put your fingers inside the tank or the capsule container.
• Do not use damaged or deformed capsules. The water may flow around a capsule that is not properly perforated and cause damage to the appliance.
• 
  To prevent burns, always use the milk container (Rapid Cappuccino System) supplied and make sure it is inserted correctly.
• If dispensing of more than 150 ml of coffee is programmed, allow the appliance to cool down for at least 5 minutes to prevent overheating.
• Descale the machine when the descaling light comes on.
  Read the precautions for use shown on the pack carefully: descaling solution can be harmful. Avoid contact with eyes, skin or other surfaces. To prevent damage to the machine, do not use products other than those provided.
