Espresso machine installation, linea mini
1) Fill water reservoir with potable water.
Once the espresso machine has been
unpackaged, placed on a hard surface.
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. 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 Marzocco

equipped with
two units of a
quick water test
kit (see image

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
