5. INSTALLING and MAINTENANCE
5.1 Hydraulic connection
The softener provided with the coffee-maker has been designed to function with a working pressure ranging between 1
and 9 bar. It must only be supplied with cold
drinking water.
When connecting to the water mains, install a cock between the machine and the mains so as to be able to interrupt
the supply of water to the appliance.
To stop the water from freezing, install the softener in a room where the temperature is higher than 0°C.
Before connecting the pipes remove any rubber plugs from the softener cock couplings. To connect proceed as follows:
When plumbing the coffee-maker do not use iron or
galvanised iron fittings because, with the passing of
time, these materials can produce dangerous
oxidations and seriously damage the machine.
attention
1) connect the water mains (
1
) to the softener inlet (
2
)
using the flexible pipe provided;
2) rinse the softener resins checking that the water, that
is initially yellow, becomes a clear colour;
3) connect the softener outlet (
3
) to the machine (
4
);
4) connect the machine drainage trough (
5
) to the drain
(
6
) using the specific pipe provided, taking care to avoid
sharp bends or throttlings and keeping it slanted
enough for the waste water to drain away;
5) the drain (
6
) must be connected to an inspectionable
trap (
7
) that can be cleaned regularly to prevent the
reflux of bad smells.
5.2 Maintenance and cleaning
To make it easier to service and clean the inside
of the machine you can remove the various parts of
the external casing.
From the front, in particular, you can access the
inside of the machine by opening the doors that cover
the unit and push button panel.
attention
To avoid damaging the outer casing, valves and cocks, install the softener where it is protected against accidental knocks.
