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 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.
