CAUTION
Installer must:
– Connect the boiler to a 230v -50Hz single phase
power supply through a fused mains switch, with
at least 3mm spacing between contacts, fused at
3amps
which ensures complete cut-off in overvoltage
category III conditions (i.e. where there is at least 3
mm between the open contacts)
.
– Respect the connections L (Live) - N (Neutral).
– Ensure that the special power cable is only replaced
with a cable ordered as a spare part and connected
by professionally qualified personnel.
m
CAUTION
Installer must:
– Connect the earth wire to an effective earthing sys-
tem.
Sime Ltd
declines all responsible for any inju-
ry or damage to persons, animals,or property as a
result of failure to provide adequate earthing of the
appliance.
