In order to enable you to check if your water
supply is within the suggested ranges, La
Marzocco machines will be equipped with
two units of a quick water test kit (see
image below) 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,
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.

2) Connect espresso machine to power supply.
Connect the espresso machine to a power
supply that is rated in accordance with the
serial plate on the espresso machine.
3) 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 re-fill the water
reservoir during this process.
Coffee boiler:
The water flows inside the
coffee boiler directly when the water pump
is activated. When the machine is turned
on the electronics will activate the water
pump to fill both boilers.
Since the inflow of water will compress
the air in the boiler it will be necessary to
remove or “bleed” the air from the coffee
boiler.
All air must be removed in order to
completely “saturate” the coffee boiler/
group assemblies.
To remove the air from the boiler, or “bleed
the group”, it will be necessary to remove
the plastic cap and the handle from the
top of the group.
Loosen the bleed screw to allow air to
escape until water flows from below the
screw head. Tighten the screw to stop the
water from flowing. Over tightening can
cause damage to the sealing washer and
the group cover.
4) Verify filling of boilers.
The installation is now complete and the
espresso machine should be heating to the
operating temperatures.
