WORDING FOR CLASS I EQUIPMENT INSTRUCTION BOOKS AND LABELS
The mains lead on this equipment is supplied with a moulded plug incorporating a fuse, the value of which
is indicated on the pin face of the plug. Should the fuse need to be replaced, an ASTA or BSI approved BS
1362 fuse must be used of the same rating. If the fuse cover is detachable never use the plug with the cover
omitted. If a replacement fuse cover is required, ensure it is of the same colour as that visible on the pin
face of the plug. Fuse covers are available from your dealer.
DO NOT cut off the mains plug from this equipment. If the plug fitted is not suitable for the power points
in your home or the cable is too short to reach a power point, then obtain an appropriate safety approved
extension lead or consult your dealer.
Should it be necessary to change the mains plugs, this must be carried out by a competent person,
preferably a qualified electrician.
If there is no alternative to cutting off the mains plug, ensure that you dispose of it immediately, having
first removed the fuse, to avoid a possible shock hazard by inadvertent connection to the mains supply.
