electrical connection with ground,
protected socket and approved
interlock switch
• Three-phase, 380VAC - 50 Hz electrical
connection with neutral + ground, near
the bench on which the machine is
installed and terminating in a suitable
protected fivepole socket equipped
with an approved interlock switch
• Waste water drain system.
Note:
• The drinking water mains valve and
the circuit breakers for the electrical
system need to be located in the most
convenient position for the operator to
access them easily and quickly.
• The machine should be placed on a flat
counter and must be placed in settings
with the following temperatures:
Minimum room temperature: 5°C/41°F
Maximum
room
temperature:
32°C/89°F
• If the machine has been temporarily
housed in settings with a room
temperature of less than 0°C/32°F,
please contact a service technician
prior to use.
• Water pressure supply must be
between 2 and 6 bar.
3) Water test kit
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.
com/water_calculator/).
4) Water supply connection
In order to connect the machine up to
the water mains proceed according to
the indications given in the chapter about
Installation 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 9°f (90ppm, 5°d) and
less than 15°f (150ppm, 8.4°d), pH should
be between 6.5 and 8.5 and the quantity of
chlorides be less than 50mg/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.
Then connect the inlet of the water filter/
softener (if present) to the drinking water
supply using one of the supplied stainless
steel braided hoses. Before connecting
the filter to the water pump, flush the
water supply line and the filtration system
in order to eliminate any residual particles
which could otherwise get stuck in taps or
valves thus preventing them from working
properly. Connect the water supply
connection of the espresso machine to
the water pump outlet using one of the
supplied stainless steel braided hoses.
