Electrical
Any electrical work shall be carried out by a suitably competent person fully in accordance
with the latest edition of the IEE requirements for electrical installations BS7671.
The appliance requires a suitable 230v AC mains supply rated at 5amp fed via a double-
pole linked isolator with a contact separation of 3mm in both poles. Details of how to
connect to the external wiring required (and the wiring provided) are shown below.
The 3kW immersion heater will require its own 230v AC mains supply. This shall be
rated at 16amp and fed via a double-pole linked isolator with a contact separation of
3mm in both poles. Details of how to wire the immersion heater are shown on page 16.
Both isolators shall be located immediately adjacent to the appliance and suitably
identified/labelled to allow safe use/maintenance.
The connections within the wiring centre are shown below.
