WARNING (KV-29FX20U only)
The flexible mains lead is supplied connected to a B.S. 1363 fused plug
having a fuse of 5 AMP capacity. Should the fuse need to be replaced,
use a 5 AMP FUSE approved by ASTA to BS 1362 , ie one that carries the
mark.
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE
FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD BE CUT
OFF AND AN APPROPRIATE PLUG FITTED. THE PLUG SEVERED
FROM THE MAINS LEAD MUST BE DESTROYED AS A PLUG WITH
BARED WIRES IS DANGEROUS IF ENGAGED IN A LIVE OUTLET
SOCKET.
When an alternative type of plug is used it should be fitted with a 5 AMP
FUSE , otherwise the circuit should be protected by a 5 AMP FUSE at the
distribution board.
How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.
