Before First Use

Cleaning The Appliance

• Carefully remove the appliance from the packaging and remove all packaging materials.
• Remove all accessories from the packaging and from the appliance.
• Remove the water tank.
• Clean the water tank with the lid, the measuring spoon and the filter as well as the filter holder with warm water and some mild dish-washing liquid. After that, rinse with clear water and dry.
• Also, wipe the casing of the espresso machine and the drip tray with the drip grid clean with a soft, damp cloth and dry all parts.
• Make sure that the steam knob is turned off (OFF position, turn all the way in a clockwise direction).

NOTE : The parts of the espresso machine and the accessories are not dishwasher safe.

Initial Use

1. Fill the water tank with cold water up to the MAX level of the tank.

2. Insert the plug into a wall outlet with a suitable voltage(120V~, 60Hz).

3. Press the Power button, the Power indicator light turns on and the coffee machine starts to preheat automatically. Once the preheating is finished, all the buttons will light up continuously. This preheating process takes about 2 minutes.

4. Place a cup under the Steam Wand. Turn on the steam knob. Let the hot water flow out of the steam wand for about 8 seconds, then turn off the steam knob. This process lets the water flow into the empty pump for the first use.
   NOTE : There will be a loud noise and a little shake when the machine running for first time. It’s normal for a 20-bar pump. The noise will be weak in the future using.

5. Insert the Filter into the Portafilter. (see image.1) NOTE: The filter might be a little tight and hard to take it out from Portafilter when you want to change the filter. You can use another filter to pry it out.(see image 1.1).

6. Insert the filter holder without coffee grounds into the brew head with a 45° movement to the left and turn it to the right to lock it in place. The Portafilter must be perpendicular to the machine or slightly tilted towards the right. (see image.2)

7. Place an empty cup under the Portafilter and press the single or double button to brew.

8. After the brewing cycle has finished, pour the water out.

Now your coffee machine is ready to use.

Preparing the Espresso
A cold Portafilter, filter and cup can reduce the extraction temperature enough to significantly affect the quality of your espresso. We recommend to ran a brewing cycle without coffee ground to preheat them before extraction.

1. Remove the Portafilter and fill the filter with coffee grounds using the tamp spoon provided with the machine.

• We recommend 7-9g for single shot and 13-15g for double shot. The amount will vary depending on your preferences and the coffee grounds you used. 2. Tamp the coffee grounds with the tamp spoon. The coffee grounds must be pressed evenly to obtain a well levelled and flat surface.
• Remove any coee residue from the edge of the Portafilter. 3. Insert the Portafilter into the brew head with a 45°movement to the left and turn it to the right to lock it in  place. The Portafilter must be perpendicular to the machine or slightly tilted towards the right.

Making the Espresso
Preparing the Espresso

1. Make sure the steam knob is on “OFF” position.
2. Place pre-warmed cup(s) beneath the Portafilter.
3. Press the single or double button for desired volume.

The default amount of single espresso is approx. 35ml. The default amount of double espresso is approx. 70ml. The flavor of your coffee will depend on many factors, such as the type of coffee beans, degree of roast, freshness, coarseness or fineness of the grind, dose of ground coffee, and tamping pressure. Experiment by adjusting these factors just one at a time to achieve the taste of your preference.

NOTE : There will be noise during the operating process. This is normal for a 20 bar pump.

Frothing Milk
To prepare a traditional cappuccino or latte, we recommend:

• using cold, fresh whole milk. The density of the frothed milk will depend on the milk fat content.
• using stainless steel, circular, rounded milk jugs, narrower at the top, with a spout, necessary to make cappuccino decorations.

Before starting, it is important to slightly move the steam wand outwards in order to insert the jug directly under it and facilitate the movements required to froth the milk correctly.

Continue as follows

1. Press the steam button. The steam button will start to flash if the temperature is not high enough to make steam. Once the preheating has finished, the Steam Button will light up.

2. Turn the steam knob slightly counterclockwise to eliminate any condensation from the wand then turn the knob off again. (see image.3.1-3.2)

3. Place the jug, half-filled with cold milk, under the steam wand.

4. Place the steam nozzle just below the surface of the milk. If it is inserted too deep, the milk will not be frothed; if it is not inserted deep enough, big bubbles will be produced and then disappear immediately.It is important to keep the Steam Tube not at the center but close to the edge of the jug, with an appropriate angle to produce a stronger vortex. (see image.4.1-4.2)

   • It is important to keep the Steam Tube not at the center but close to the edge of the jug, with an appropriate angle to produce a stronger vortex.

5. Turn the steam knob to position. The steam will come out of the steam wand.
   NOTE : The entire operation should last no longer than 3 minutes because the machine will stop making steam automatically after 3 minutes of continuous steaming.
   NOTE : To froth the milk correctly, the steam nozzle must always be in contact with the milk and not with the froth. Therefore, as the layer of froth increases, the jug must be slightly raised trying to keep the Steam Tube in contact with the milk, without touching the bottom of the jug.

6. Once the desired frothing has been achieved, the steam nozzle must be pushed deeper to heat the milk well.
   NOTE : It is advisable to always keep a hand on the rounded part of the jug to feel the temperature increase of the unfrothed milk.

7. Once the desired result has been achieved, turn the steam knob to the “OFF” position to stop dispensing steam and remove the jug.
   NOTE : To make the froth more compact, it is advisable to lightly tap the jug on a flat surface after frothing.

8. Press the steam button again to quit the steam mode. Pour the frothed milk into the coffee.
   WARNING The steam wand may be very hot during and after use. To avoid burns, move it only by placing your fingers on the rubber tip fitted to the steam wand.

9. Turn the steam knob on to eliminate any residue milk from the wand then turn the knob again.

10. Do not make coffee immediately after frothing milk. The temperature of the boiler is too high, and the machine is under the overheating protection. Under the protection, the single and double buttons will flash if you press either of them.

Over-heating Protection
After having used the steam wand and exited the steam function, the machine is under the over-heating protection. Under the protection, the single and double buttons will flash simultaneously if you press either of them, indicating that the boiler needs to be cooled in order to reach the precise espresso brewing temperature. Please proceed as below 4 steps to cool down the machine:

• Under the over-pressure protection, turn the steam knob to position to make hot water.
• Let hot water come out from the steam wand to cool down the boiler.
• Once the temperature of boiler is cool down, all the buttons will fully illuminated.
• Return knob to the “OFF” position, and the coffee machine is ready for the next brew.

Making Hot Water

1. Turn the machine on and wait until all the buttons light up.
2. Place a cup under the steam wand.
3. Turn the steam knob to position. The hot water will come out of the steam wand.
4. Once the desired amount of hot water has been dispensed, turn the steam knob off.

NOTE: The eng to verter a should lay ate rehan dO scond, be we the thin rail nore hot water, ran the cycle again.

Cleaning and Maintenance

Regular cleaning and maintenance keep the machine in working condition and ensure perfect coffee flavour, a constant coffee flow, and excellent milk froth for a long period of time.

Cleaning the Portafilter and the filters
The Portafilter and filters should be kept clean to guarantee perfect results.

WARNING: To avoid burns, the filter must only be removed when the Portafilter has cooled down completely.

1. Remove the filter from the Portafilter and wash them with warm water.
2. If you notice a malfunction when brewing coffee, immerse the filter in boiling water for 10 minutes and then rinse with running water.

NOTE : Do not clean any of the parts in the dishwasher.

Cleaning the Steam Wand

1. Immediately after frothing milk, turn steam knob on to purge out any residual milk from the steam wand.
2. Clean the steam wand with a damp cloth. To clean it more thoroughly, you can unscrew the steam nozzle and wash it with running water.
3. If the hole of the steam nozzle become blocked, ensure the steam knob is in the STANDBY position. Press the power button to turn the machine off and allow to cool. Use a pin to unblock the hole. (see image.9)

Cleaning the Brew Head
Regularly remove any residual coffee grounds from the brew head using a brush, and wash with hot water following the steps below.

• Insert the filter holder into the brew head without using coffee grounds.
• Place an empty cup under the brew head.
• Press the double button and fill the cup with water.
• Remove the filter holder from the brew head and clean the brew head with a dry cloth.

WARNING; Do not try to disassemble the brew head. It will damage the Brew Head and lead to leakage.

Descaling
To make sure your coffee maker operates efficiently, to clean the internal pipes, and to preserve the flavor of your coffee, the coffee machine needs to be descaled, cleaned and maintained periodically. Also, after 500 times of brew cycle, a descaling warning will be shown. The power button will flash 5 times to indicate it is time to descale the machine. The descaling warning will appear at every time start-up if you do not run a descaling cycle. Please proceed as below steps to descaling the machine.

1. Fill the water with descaling agent(4 parts water to 1 part descaling agent) into the water tank up to the Max marking.
   NOTE : Please also refer to the instructions on the descaling agent. Please use a household descaling agent, or you can use citric acid instead of a commercial descaling agent – in this case use 100 parts of water to three parts of citric acid.

2. Place a cup/mug or other suitable receptacle on the drip tray and keeping press the double and steam button together for 5 seconds. The machine will start the descaling cycle, and the descaling cycle will run 7 minutes then stop automatically. (see image.10)
