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.
The equipment is to be installed with
adequate backflow protection to comply
with applicable federal, state, and local
codes.
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),
