WARNING: THIS APPLIANCE MUST BE EARTHED
All external wiring must comply with the IEE Regulations
for the Electrical Equipment of Buildings. Connection to the
electrical supply can be made with either a plug and socket
or be permanently wired via a double pole switch. The cooker
is supplied with a 3-core cable 2m long. If a replacement
cable is fitted it must be 250V high temperature PVC (85°C),
1mm².
Should the plug not fit the socket in your home, it should be
removed and replaced with a suitable plug.
Note: If the plug is fitted is not suitable, it must be cut off and
disposed of properly. To avoid the risk of electrocution, the
plug must not be left where children might find it and plug it
into a supply socket.
Three pin plugs to BS 1363 with a capacity of not less
than 13A must be used and fitted with a 3 amp fuse 'ASTA'
approved to BS 1362.
After replacing the fuse the cover must be refitted. If the
cover is lost, the plug must not be used until a replacement
cover has been obtained from your supplier. The colour of the
correct fuse carrier is that of the coloured insert in the base of
the fuse recess, or stated elsewhere on the plug. Always state
this colour when ordering a replacement fuse carrier.
