Espresso Machine Installation, GS/3
1) Fill Water reservoir with potable water.
Remove the drain tray and slide the
water reservoir until the water reservoir
fill cover is accessible. Remove the cover
and fill water reservoir with potable water.
Replace the fill cover and slide the water
reservoir to the operating position and
replace the drain tray. (See GS/3 Software
and Installation Guide for additional
instructions). In order to connect the
machine up to the water mains proceed
according to the indications given in the
Installation Guide 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 7°f (70ppm,
4°d) and less than 10°f (100ppm, 6°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.
In order to enable
you to check
if your water
supply is within
the suggested
ranges, La
M a r z o c c o
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/).
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.
Once the espresso machine has been
unpackaged, placed on a hard surface,
and with the water reservoir full, it will
be necessary to fill the boilers with water.
Complete the following steps to properly
fill the boiler tanks:
Steam Boiler: Turn the main switch to
position “1” or ON, the automatic steam
boiler level system will be switched on,
activating the auto-fill solenoid valve and
the water pump. This will fill the steam
