2.8 CONNECTION TO
ELECTRICITY SUPPLY
For the electricity supply, which must have
single phase voltage of 230V-50Hz, connect
the three-pole wire supplied with the boiler
to a mains switch protected with fuses, with
a distance between contacts of at least 3
mm. In the case of replacement, the said
wire must be requested from SIME.
PLEASE NOTE: The appliance must be con-
nected to an efficient earth system.
SIME declines all responsibility for dama-
ges to persons or property deriving from a
non-earthed boiler.

For access to the panel, switch off the elec-
tricity and unscrew the screws fixing the

The panel can be made to slope downwards
by removing the two lower screws that hold
it to the frame.
