Plug FFitting IInstructions ((UK o

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 a 13 Amp (BS 1363) 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.
