Machine Description

Installation

Espresso machine installation, linea mini

Fill the water reservoir with potable water.

Once the espresso machine has been unpackaged, place it on a hard surface. Remove the drain tray and slide the water reservoir until the water reservoir fills the cover is accessible. Remove the cover and fill the water reservoir with potable water. Replace the fill cover and slide the water reservoir to the operating position, and replace the drain tray. In order to connect the machine up to the water mains, proceed according to the indications given in the Installation Guide and in compliance with any local/national safety standards of the location in which the machine is being installed.

To guarantee a correct and safe functioning of the machine and to maintain an adequate performance level and a high quality of the beverages being brewed, it is important that the incoming water be of a hardness greater than 7°f (70ppm, 4°d) and less than 10°f (100ppm, 6°d), pH should be between 6.5 and 8.5 and the quantity of chlorides be less than 30mg/l. Respecting these values allows the machine to operate at maximum efficiency. If these parameters are not present, a specific filtration device should be installed, while always adhering to the local national standards in place regarding potable water.

In order to enable you to check if your water supply is within the suggested ranges, La Marzocco machines will be equipped with a quick water test kit, including 6 test strips and instruction cards. The parameters that you can measure are Total Hardness, Total Iron, Free Chlorine, Total Chlorine, pH & Total Alkalinity, and Chlorides. Ideally, you should perform a test on the water BEFORE the water treatment system and again AFTER the water system in order to verify if this is actually matching our suggested ranges.

Once the test has been performed, learn which treatment system is most appropriate for your particular water supply by filling out the online water calculator on our website: LA MARZOCCO WATER CALCULATOR (http://www.lamarzocco.com/water_calculator/).

Connect the espresso machine to the power supply.

Connect the espresso machine to a power supply that is rated in accordance with the serial plate on the espresso machine.

Filling the boilers with water.

Complete the following steps to properly fill the boiler tanks:

Steam boiler: Turn the main switch to position “1”, the steam boiler will then automatically fill to a predetermined level. When the correct water level in the steam boiler is reached, the machine will automatically stop filling.

NOTE: It may be necessary to refill the water reservoir during this process.

Integrated brew group: The water flows inside the Integrated brew group directly when the water pump is activated. When the linea mini is turned on, the electronics will activate the water pump to fill both boilers.

Verify the filling of boilers.

The installation is now complete, and the espresso machine should be heating to the operating temperatures.

Brewing after the first installation

Once the first installation procedures are finished, before proceeding with brewing coffee, hot water, and steam, please follow these steps:

• Engage the portafilter by inserting it into the group head and rotating the handle from left to right. Once the portafilter is inserted properly, you can move the paddle on the left side to start the flow of water through the portafilter. Brew water through the group for at least two minutes.
• Being careful to avoid burns, turn on the steam wand for at least one minute.
• Turn on the hot water valve for the time necessary to allow at least 1 liter of water to be brewed.

Adjusting water pump pressure.

The water pump is factory set at 9 bar pressure. If it becomes necessary to change the pressure, please use the following procedure:

1. Locate the water pump adjustment screw and loosen the lock nut.
2. Adjust the water pump pressure to the desired measurement.
3. Rotate clockwise to increase pressure and counter-clockwise to reduce pressure.

Operation

Installing the portafilter.

Install the portafilter by inserting it into the integrated brew group and rotating the handle from left to right. Once the portafilter is inserted properly, you can move the paddle handle from right to left to start the flow of water through the portafilter. It is important that the portafilter is at operating temperature prior to filling with coffee.

Allow hot water to pass through the empty portafilter for a few seconds before the brewing process to preheat the portafilter.

NOTE: It is important to leave the portafilter locked in the espresso machine when not in use. The portafilter must remain heated for the brewing process to function correctly.

Brewing coffee.

It is now possible to remove the portafilter to make a coffee beverage. Place some ground coffee in the portafilter basket using the single or double basket. Press down on the ground coffee with the supplied tamper and install the portafilter on the Linea Mini. Move the paddle handle from right to left to begin brewing (see Fig.1, page 8).

With the La Marzocco App, it is possible to adjust the temperature of the coffee brewing water. It is recommended to wait for a few seconds until the desired temperature is achieved.

If you want to decrease the temperature, it is recommended to dispense water from the group for a few seconds to speed up the process.

NOTE: Some users believe it is important to allow water to pass through the integrated brew group prior to installing the portafilter to flush any remaining coffee oils and particles from the integrated brew group. Some also flush just after brewing for the same reason. Please experiment to make the best possible procedure for your coffee. There are many techniques for brewing espresso. You can find instructions for many techniques on websites, blogs, and forums.

Dispensing hot water.

You may dispense hot water by using the hot water nozzle. To dispense hot water rotate the left knob (see Fig.4 page 14). This knob commands the hot water delivery.

Activation of the flush function.

The flush function is activated by operating the lever shown in Figure 5, turning it from the dispensing position to the deactivation position within 1 second. The machine will dispense hot water for a certain number of seconds (the default setting is 5 seconds, but this can be changed via the App).

Preventative Maintenance and Cleaning

Cleaning (Daily)

Cleaning the diffuser screen and diffuser screw.

During the discharge operation (subsequent to coffee brewing), small amounts of coffee grounds may slowly build up on and obstruct, even partially, the diffuser screen. Turn off the machine and remove the diffuser screen by unscrewing the diffuser screw. Soak in detergent powder liquid following the instructions of the detergent manufacturer. Rinse thoroughly with clean water, puro caff. Install and run hot water through the group head several times with the screen installed.

Cleaning the brewing system.

Insert the blank basket into the portafilter and put the correct amount of espresso cleaning product (following the product’s instructions) into the filter, engage the portafilter into the Integrated Brew Group.

• Move the group activation paddle for said group, as if you were making a regular cup of coffee. Stop the water after about 15-20 seconds.
• Start and stop the group several times until you notice clear water being released instead of soapy water when you remove the portafilter. Do not remove the portafilter when the group is dispensing water.
• Rinse the group using a normal filter in the portafilter by running hot water through it several times.

Cleaning the body.

Wipe the stainless steel surfaces with a soft, non-abrasive cloth in the direction of the glazing marks, if any. Do not use any alcohol or solvents whatsoever on painted, imprinted, or plastic parts in order not to damage them. Clean the side panels using a soft cloth. Clean only with a damp, soft cloth or possibly soaked in warm water and mild soap.

Cleaning the steam nozzles.

Steam nozzles must be cleaned immediately after use with a damp cloth and by producing a short burst of steam so as to prevent the formation of deposits inside the nozzles themselves, which may alter the flavor of other drinks to be heated. If milk residue is present on the steam wand, soak the tip in a container of hot water, then it will be possible to wipe the tip clean. Repeat the process if residue remains.

Cleaning the hot water nozzles.

Hot water nozzles must be cleaned periodically with a damp cloth soaked in water and/or mild soap.

NOTE: This cleaning schedule is based upon a moderate to average use (5-20) cups per day. If machine use is less than moderate, then this schedule may be adjusted accordingly.

Clean the water reservoir and the drain box:

The water reservoir needs to be cleaned periodically to ensure that no algae forms on the inside surfaces. To clean, first remove the water reservoir from the machine. Disconnect the clear plastic water intake hose. Hand wash each part with water containing mild soap.

Steam boiler draining.

Yearly, we recommend to fully drain the steam boiler by means of the specific drain cock located on the side of the boiler or under the boiler.
