Should this require replacement, it must be
purchased exclusively from SIME.
The electric power supply to the boiler must
be 230V - 50Hz single-phase through a
fused main switch, with at least 3 mm spa-
cing between contacts. Respect the L and N
polarities and the earth connection.
NOTE: SIME declines all responsibility for
injury or damage to persons, animals or
things, resulting from the failure to provi-
de for proper earthing of the appliance.

1500 mm must be adopted, unless
adequate shielding is provided to
guard these materials.
