4. Ensure enough free space is available above (>30cm) and behind (>10cm) the machine to ensure easy cleaning and maintenance and adequate ventilation.

Important:

Leave an air gap of at least 30cm above the machine and 10cm behind it to ensure adequate ventilation. The machine must be installed within 3º of horizontally level front-to-back and side-to-side to ensure proper hydraulic function and drainage. Confirm with a spirit level or digital angle gauge.

Do not install the machine if the machine or installation surface it is wet. Allow it to dry completely and ask a service technician to ensure that none of the electrical components have been affected.

Original instructions.

INSTALLATION AND START UP

· Mains water connection

1. Connecting the machine to the domestic water supply must be performed by a qualified person. Contact a service technician to do this task you are not confident about performing the steps below.

2. Purge at least 20 liters of water from the domestic water supply before connecting the machine to it to flush out any debris that may be in the plumbing system that would otherwise accumulate inside the boilers.

3. The domestic plumbing system should be fitted with a brass 3/8” NPT male pipe fitting and an in-line shut-off valve. Connect the 180cm water inlet hose included with the machine to the domestic water supply and tighten the line fittings with a wrench to 15 ft. lbs. / 20N-m.

Important:

Use the inlet hose included with the machine to connect it to the water mains in accordance with the national rules applicable in the country where machine is installed. Never reuse damaged hoses

Important:

To prevent limescale build up in the boiler and other components, a water-softening system must be installed in-line ahead of the machine.

Read more on section for water filter requirements.

· Water filter requirements

Only use safe drinking water with a hardness rating between 5ºfH and 8ºfH (French hardness degrees). If the hardness value is below this limit, corrosion of hydraulic components is likely. If the value is higher, lime-scaling inside the boiler will occur. In both cases, the proper function of the machine and quality and taste of the coffee will be negatively affected.

If drinking water is not within the ratings shown above, a water filter must be installed inline ahead of the espresso machine. Failure to install a water filter will result in voiding of the warranty and any damage resulting from limescale buildup will be the responsibility of the owner.

Filtration device

1. Ensure that a water filtration device or system is installed in-line in the domestic water supply ahead the machine to prevent contamination inside the machine’s hydraulic system. Contact a service technician to do this task if you are not confident about performing the steps below.

2. Open the water tap and allow the filter to fill (if new/previously unused). Then the machine’s steam boiler will begin to fill. Check carefully around the service area for leaks or drips. If leaks/drips are detected turn off the tap immediately and check/tighten any leaking fittings.

3. If necessary, connect the machine to a water softener to reduce water hardness using the flexible 55cm hose included in the accessory box.

Important:

Always maintain the water filtration device or system in accordance with the manufacture’s specifications. Failure to routinely maintain the filtration device or system will result in limescale build-up inside the machine’s hydraulic system which will eventually result in machine failure. Please read more under the cleaning and care section.
