SAFETY PRECAUTIONS
Plug Fitting Instructions (UK only)
The cord supplied with this appliance is factory fitted with a 13A mains plug fitted
with a 3A fuse inside. If it is necessary to change the fuse, it is important that
a 3A one is used. If the plug needs to be changed because it is not suitable for
your socket, or becomes damaged, it should be cut off and an appropriate plug
fitted following the wiring instructions below. The plug must then be disposed
of safely, as insertion into a 13A socket is likely to cause an electrical hazard.
Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires
should be fitted as shown in this diagram. The colours of the wires in the mains
lead of this appliance may not correspond with the coloured markings identifying
the terminals in your plug. Connect them as
follows:-
• The wire which is coloured BLUE
must be connected to the terminal
which is marked with the letter ‘N’ or
coloured BLACK.
• The wire which is coloured BROWN
must be connected to the terminal which
is marked with the letter ‘L’ or coloured
RED
• The wire which is coloured GREEN/
YELLOW must be connected to the terminal which is marked with the letter
‘E’ or coloured GREEN.
Note
If your model does not have an earth wire, then disregard the Earth instruc-
tion.
If a 13 Amp (BS 1363) plug is used, a 3 Amp fuse must be fitted, or if any other
type of plug is used a 3 Amp or 5 Amp fuse must be fitted, either in the plug
or adaptor, or on the distribution board.
