6.0 INSTALLATION - ELECTRICAL
REQUIREMENTS
6.1 This appliance must be earthed.
6.2 The installation, supply cable and circuit protection must conform
to the latest BS7671 ‘Requirements for electrical installations’ (IEE
Wiring Regulations).
6.3 The appliance must only be connected to a 230/240 V ac supply.
A double pole isolating switch, with a contact separation of at least
3mm in both poles, must be incorporated in the electrical supply.
The supply should be fused 13Amp.
6.4 If the Supreme is to be unused for significant periods of time running
costs can be reduced by switching the unit off. It is recommended
that this is done automatically by incorporating a suitable timeswitch
in the supply to the unit. The use of an accessory no. 95 970 124 is
recommended. The timeswitch can then be set to switch the unit
on for a suitable period to allow it to heat up before it is next to be
used.
NOTE : A timeswitch must be capable of switching 13 Amps resistive load.
