INSTALLATION AND START UP
Machine positioning
MIN. 10 cm
MIN. 30 cm
Install within 0-3º horizontal.
1. Installing the machine in the service area must be performed by a qualified person. As the machine may be quite heavy, at least two strong, capable individuals are recommend to work together to lift and position the machine. Consult the Technical Specifications page for the specific machine model being installed for machine weight and dimensions details. Contact a service technician to do this task if you are not confident about performing the steps below.
2. Position the machine on a level, sturdy, and water-resistant surface approximately 110cm above floor level for ease of access and usage.
3. Adjust the feet to ensure that it dispenses coffee evenly to all cups.
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.

INSTALLATION AND START UP
Drain connection checklist
1. Connect one end of the exible drain
tube to the drain cup outlet by inserting it through the access hole in the panel mounted in the bottom of the chassis. (It is located under the drip tray and grill. Contact a service technician to do this task you are unsure how to access this area of the machine.)
2. Connect the other end of the drain tube to the domestic plumbing drainage system in the service area.
3. Replace/reinstall the drip tray and grill.
Flexible drain tube
Drain cup
Pro Tip:
Ensure that the drainage tube is not twisted and that it is below the level of the drain cup to prevent trapping water and other residue in the tube which could mold or produce bad smells.
Page 17
DIAMANT Pro
17
INSTALLATION AND START UP
1. Connecting the machine to the domestic water supply must be performed by a qualied person. Contact a service technician to do this task you are not condent 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 ush out any debris that may be in the plumbing system that would otherwise accumulate inside the boilers.
3. The domestic plumbing system should be tted with a brass 3/8” NPT male pipe tting and an in­line shut-off valve. Connect the 180cm water inlet hose included with the machine to the domestic water supply and tighten the line ttings with a wrench to 15 ft. lbs. / 20N-m.
4. Ensure that a water ltration 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.
5. Open the water tap and allow the lter to ll (if new/previously unused). Then the machine’s
steam boiler will begin to ll. 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 ttings.
6. Only use safe drinking water with a hardness rating between 5ºfH and 8ºfH (French hardness degrees) or 20 to 32 ppm (parts per million of calcium). 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.
7. If necessary, connect the machine to a water softener to reduce water hardness using the exible 55cm hose included in the accessory box.
Important:
Only use the hoses supplied with the machine. Never reuse damaged hoses. If the machine is to be moved or relocated, replace the hose set with a new parts from the distributor/ manufacture.
Water connection checklist
Pro Tip:
Always maintain the water ltration device or system in accordance with the manufacture’s specications. Failure to routinely maintain the ltration device or system will result in limescale build-up inside the machine’s hydraulic system which will eventually result in machine failure.

Steaming milk with the SmartSteam
OPERATION
1. Aim the SmartSteam wand down towards the drip tray and tip the handle up to flush the steamer and eject any condensed water inside the system. If you have used your “SmarSteam”
system after a long period of inactivity it’s recommended to do a long ushing (6 to 10s) before frothing.
2. Place the milk pitcher on the drip tray with the
SmartSteam wand immersed into the milk. Start
the SmartSteam by tipping the handle down. It will stop automatically when the programmed temperature is reached.
Flush
Start
WARNING!
Do not remove the pitcher or allow the steam wand to extend out of the milk while steaming, it may cause serious burns and injuries.
3. When the steaming is nished, remove the milk
pitcher. Then aim the SmartSteam wand down towards the drip tray and tip the handle up to flush the steamer and eject any milk that may be in the steam tip. Afterward, wipe down the outside of the SmartSteam wand and with a damp cloth to prevent nozzle blockage and to keep everything clean.
Flush
Pro Tip:
If you don’t nd your wished foam you can play with settings “pump speed” and “SmartSteam offset”. For a more liquid : reduce pump speed and/or increase “SmartSteam offset”. For thicker foam: increase pump speed and/or decrease “SmartSteam offset”
Note:
SmartSteam optional includes 2 different nozzles. Baristas and Turbo. Default settings are according to “Barista” nozzle (much slower but supreme quality). For using the turbo nozzle you need to modify settings to 65% pump speed and 0-5ºC offset.

CLEANING AND CARE
• To keep the machine looking and working like new, always follow all the cleaning and care instructions provided in this manual.
• For safety always turn the machine off at the main power switch when cleaning the exterior surfaces.
• All exterior surfaces should be cleaned with a damp, lint-free cloth that will not scratch the machine, glass surfaces can be cleaned with a streak-free glass cleaner and a dry cloth.
• Do not use aggressive cleaning detergents, solvents or degreasers. These may damage the plastic and rubber parts, and will leave unwanted residue.
At the end of each working day be sure to:
1. Position the steam wand over the drip tray and open the steam lever for one minute to fully flush the wand. Repeat for each steam wand.
2. Place a container under the water outlet and activate the hot water dispensing for a total of 20 seconds to fully flush the tap.
3. Run the Daily flushing cycle for each brewing group. See Daily flushing section for details.
4. Clean the external surfaces of the machine, paying special attention to the glass and stainless steel parts to remove any coffee residue and smudges and fingerprints.
Once per week be sure to:
1. Clean the drain cup by slowly pouring one liter of warm water into it to dissolve and remove any build-up of coffee residue that often accumulates inside the drain cup and tube.
2. Clean the dip tray and the stainless steel insert grid under running water with a brush.
3. Clean the steam wand and the water tap. Be sure that the nozzles are not clogged or partially blocked with milk or other residue. If it’s necessary to remove them for cleaning, be careful not to deform or damage any of the components during removal.
4. Run the Weekly cleaning for each brewing group. See Weekly cleaning with espresso machine detergent section for details.

Pro Tip:
Preinfusion is a useful feature for many roasts of coffee that need just a little more time to “develop” during brewing. Preinfusion moistens the espresso in the portalter for about one second, then releases pressure for two seconds before begging the normal brew. To decide if preinfusion is best for your specic coffee roast, it is recommended to do a taste comparison with and without preinfusion, then set up your machine according to what tastes best to you.

Group cleaning
Important:
When using this function to perform the weekly cleaning with espresso machine detergent no water will ow from the group when the portalter with blind lter is installed, however hot water will still ow from the other groups, so the cleaning with detergent must be repeated separately for each group. It is important to perform two or three more clearings without detergent afterward for each group to ensure all detergent has been ushed out of the group.
WARNING!
THE CLEANING WATER IS VERY HOT! DO NOT PLACE FINGERS OR HANDS UNDER THE GROUP, OPEN THE GROUP OR REMOVE THE PORTAFILTER UNTIL THE CLEANING CYCLE HAS FINISHED TO AVOID SCALDING OR BURNS! WAIT 3-4 SECONDS AFTER DISPENSING HAS FINISHED BEFORE REMOVING THE PORTAFILTER TO ALLOW PRESSURE TO RELEASE.
Pro Tip:
Optionally, as a time saving step,weekly cleaning with detergent can be done on all groups simultaneously if extra blind lters are purchased for use with the extra groups. Ask your distributor about purchasing extra blind lters if desired.
Use the following steps to activate the automatic group cleaning cycle for the brewing groups:
1. Press the Group Cleaning button to enter the programming menu.
2. Select the group to be cleaned, or select the brush button to clean all groups simultaneously. Use the X to exit.
Note:
Automatic group cleaning with detergent takes approximately four minutes.

Alarms related with SmartSteam functionality
Alarm Description
Cooler temp
recommended
If the SmartSteam temperature probe detects that the milk in the jug is above 10ºC the warning will appear and the steaming cycle will not start until cold milk is used. Using warm milk is a food-safety risk and warm milk will not produce high quality foam.
SmartSteam clean due
If the programmed cleaning interval time for the SmartSteam (set at ve minutes by default) expires without the barista activating the cleaning cycle manually, the barista must return the SmartSteam to the down position. Then, 30 seconds later the machine will display Steamer cleaning and start the cleaning pulses to ush the steamer.
Flush short, ush again
If the barista attempts at manual flush of the SmartSteam but does not complete the full required flushing time as defined in the programming, a warning will be displayed and the flushing must be run again.
Alarms related with Group use
Alarm Description
Group cleaning overdue
If the programmed daily cleaning interval time (set at 24 hours from last cleaning by default) expires without the barista activating the cleaning cycle manually, the warning will appear and will remain on screen until the cleaning is completed.
Group over-use warning
