Factory fitted moulded mains plug
1. The mains plug contains a fuse. For replacement, use only a 13-Amp
ASTA-approved (BS1362) fuse.
2. The fuse cover must be refitted when replacing the fuse in the
moulded plug.
3. 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 adapter, or consult your dealer.
If nonetheless the mains plug is cut off, remove the fuse and dispose
of the plug immediately, to avoid a possible shock hazard by
inadvertent connection to the mains supply.
IMPORTANT: The wires in the mains lead are coloured in accordance
with the following code:
Blue: Neutral
Brown: Live
Do not connect those leads to the earth terminal of a three-pin plug.
Caution : Read this section carefully to ensure safe operation.
*AC voltage selection
The AC voltage selector switch on the rear panel is set to the
voltage that prevails in the area to which the unit is shipped. Before
connecting the power cord to your AC outlet, make sure that the
setting position of this switch matches your line voltage. If not, it
must be set to your voltage in accordance with the following
direction.
Note:
Our warranty does not cover damage caused by excessive line
voltage due to improper setting of the AC voltage selector switch.
