– WATER INSTALLATION RULES
Water used in coffee machines must be potable and suitable for human consumption (see laws and regulations in
force).
Check on the machine’s water inlet that the pH level complies with the laws in force and that the chloride value is
less than 100 mg/l
If the values do not fall within the limits, an appropriate water treatment device must be inserted (respecting the
local laws and compatible with the machine).
If the machine uses water with a hardness exceeding 8°F (4.5 °D), a specific maintenance plan must be
implemented according to the hardness detected and machine usage.
Only use the supplied parts for installation. If other parts are installed, they must be new (not used) and they must
be able to come in contact with potable water suitable for human consumption (according to local laws in force).
Place the machine on a flat surface and stabilize it by adjusting and securing the feet.
Hook up
the water connections respecting the hygiene, water safety, and antipollution laws in the country of
installation.
If the water pressure can rise above 6 bar, install a pressure reducer set at 2÷3 bar.
Place the end of the water draining tube in a drain with a siphon for inspection and cleaning.
The curves of the draining tube must NOT bend.

– GETTING THE MACHINE READY FOR USE
Once the hydraulic and electrical installations are over, proceed to get the machine ready for use.
Open the tap of the water mains and close the general protection switch.
Switch on the main switch I/O placing it on the position I, the relative pilot light will go on.
The self-levelling device will start working in order to fill the boiler with water until the right level is automatically
reached.
Once the water has been automatically pumped into the boiler, the boiler heating element will start heating it.
Wait until the machine has reached the exercise nominal pression of 1÷1,2 (check the relative manometer).
Should the machine not reached the above values, the pressure switch will have to be re-calibrated.
The machine is ready for use.

– INSTALLATION CHECK-UP
Once the installation is over, check if the machine is working properly.
Verify that there are no leaks from the connections or tubes.
Verify that boiler and operating pressure comply with the nominal values.
Verify that the pressure gauge is working properly.
Verify that the self-leveling device is working properly.
Verify that the expansion valve is working properly.
Verify that the electrical cup warmer (if available) is working properly.
WARNING: ONCE THE MACHINE HAS BEEN INSTALLED AND IS READY FOR USE, BEFORE
ALLOWING THE WORKER TO START USING THE MACHINE, WASH THE INTERNAL COMPONENTS
ACCORDING TO THE INSTRUCTIONS BELOW:
Groups
Hook up the filter holders to the groups (without coffee).
Let each group dispense water for about a minute.
Hot water
Continuously dispense hot water (opening the relative knob) until at least 4 liters of water come out of the
machine.
Steam
Dispense steam from the nozzles for about a minute, using the appropriate knob.
