Electrical connection
All electrical work should be carried
out by a suitably qualified and
competent person, in strict
accordance with current local and
national safety regulations (BS 7671
in the UK).
Installation, repairs and other work
by unqualified persons could be
dangerous. The manufacturer
cannot be held liable for
unauthorised work.
Ensure power is not supplied to the
appliance until after installation work
has been carried out.
The appliance must only be
operated when built-in. This is to
ensure that all electrical parts are
shielded. Live parts must not be
exposed.
Do not connect the appliance to the
mains electricity supply via an
extension lead. These do not
guarantee the required safety of the
appliance.
Please ensure that the connection data
quoted on the data plate match the
household mains supply.
Connection should be made via a
suitable isolator or a double pole fused
spur connection unit or fused plug and
switched socket which complies with
national and local safety regulations
and the on/off switch should be easily
accessible after the appliance has
been built in.
If the switch is not accessible after
installation (depending on country) an
additional means of disconnection must
be provided for all poles.
For extra safety it is advisable to install
a residual current device (RCD), with a
trip current of 30 mA.
When switched off there must be an
all-pole contact gap of 3 mm in the
isolator switch (including switch, fuses
and relays).
Important U.K.
This appliance is supplied for
connection to a single phase 230-240 V
50 Hz supply with a 3-core cable.
The wires in the mains lead are
coloured in accordance with the
following code:
