WARNING ( KV-X2972U 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 YOUR SOCKET OUTLETS 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 SOCKET OUTLET.
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.
Open the fuse compartment with the
