ELECTRICAL CONNECTION
The boiler is supplied with an electric
cable. Should this require replace-
ment, it must be purchased exclusi-
vely 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. The room stat
must be class II as specified by stan-
dard EN 60730.1 (clean contact).
NOTE: Device must be connected to an
efficient earthing system. SIME decli-
nes all responsibility for injury or dama-
ge to persons, animals or things, resul-
ting from the failure to provide for pro-
per earthing of the appliance. Always
turn off the power supply before doing
any work on the electrical panel.
