Part 9. Connection to the mains water supply and to the electrical supply
9.1 Connection to the mains water supply
Before proceeding to the connection carry out the following checks on the water to be used:
- Make sure that the water supply is of drinking quality possibly through certificate of a laboratory;
- Make sure that water mains pressure ranges from 1 to 8 bar;
- If the mains pressure is lower than 1 bar, a pump must be installed;
- If the mains pressure is higher than 8 bar, a pressure reducer must be mounted, calibrated at 3
bar, on the water connecting hose of the machine; in any case the mounting of a pressure reducer
is advisable in all installations where high pressure peaks occur.
If not already existing, install a 3/8" gas tap to exclude the machine from the mains source in case
of emergency.
Connection of the tap to the machine must be made with a copper or plastic hose, which has been
approved for food contact use and resistant to operating pressure not lower than 10 bar.
Make sure that the water is free of impurities and does not feature excessive hardness (higher than
20 French Degrees). This shortcoming can be solved using normal water softeners. The SAGOMA
machines, models
E
and
FB
, are complete with a standard water-
softening filter. The models
H
can be provided with an optional filter.
Lime scale can be notably reduced by the use of the filter, ensuring a
longer life of all components in contact with water and reducing
maintenance.
Carry out the connection on the inlet coupling of the water softener
or, should the filter not be mounted, directly on the inlet coupling of
the water inlet solenoid valve.
The water softener and the water inlet solenoid valve are both
provided with a 3/8" gas male inlet coupling.
If a water softening filter is mounted, the water hardness must be
taken (special kits are available for sale) in order to define how often
the filter shall be regenerated. This depends on the rate of use of the
filter and on the grade of water hardness (see section "Regeneration
of the water softener filter").
9.2 Connection to the electrical supply
Make sure that the grounding of the electrical mains to which the machine
will be connected is in good conditions and in compliance with domestic
and European standards concerning electrical safety.
The machine is equipped with a power supply cord H50VV-F 3x1.5 mm2
with Shucko plug.
Make sure that the electrical mains voltage is the same as indicated on
the identification sticker of the machine and that the current rating of the
plug is suitable for the current absorbed by the machine. The identification
sticker is put inside the machine and can be seen opening the door. For
connection, an electric plug, single-phase, 230V 50 Hz, for a maximum
load of 15A is required.
Any type of plug, which is incompatible with the socket of the machine,
must be replaced.
Do not use adaptors or multiple plugs.
