Caution - Danger of Death 230V AC
Lethal Voltage present on the AC supply.
WARNING - THIS APPLIANCE MUST BE EARTHED
The installation, supply cable and circuit protection must conform to the current wiring regulations
and be sufficient for the amperage required and length of cable run. Before making electrical
connections within the installation, ensure that the electrical supply has been isolated.
The shower must be connected to its own independent electrical circuit.
DO NOT connect any other device to the power source.
Check your consumer unit (main fuse box) has a main switch rating of 80A or above and that it has
a spare fuse way which will take the miniature circuit breaker (MCB) necessary for the shower (see
schematic of installation circuit). If your consumer unit has a rating below 80A or if there is no spare
fuse way, then the installation may require a new consumer unit serving the property or just the
shower. Contact the local electricity company if in any doubt.
The current carrying capacity of the cable must be at least that of the shower circuit protection.
Refer to the current wiring regulations to determine minimum cable size. A maximum of 10mm
2
can
be fitted to the shower. Site conditions must be assessed by a competent electrician to determine
correct cable size and permissible circuit length.
Shower circuit cable separation from other circuits must meet wiring regulations.
This appliance is only intended to be permanently connected to the main power supply and has an
independent double-pole isolation switch. Other electrical equipment must not be connected to the
same shower circuit. A 30mA residual current device (RCD) MUST be installed. This may be part of the
consumer unit or a separate RCD unit.
This appliance must be earthed.
