6 A 45 amp double pole isolating switch with
a minimum contact gap of 3 mm in both
poles must be incorporated in the circuit.
6.1
It must have a mechanical indicator
showing when the switch is in the OFF
position, and the wiring must be connected
to the switch without the use of a plug or
socket outlet.
ELECTRICAL REQUIREMENTS
The installation, supply cable and circuit
protection must conform with BS7671 (IEE
wiring regulations) and be sufficient for the
amperage required.
The following notes are for guidance only:
1
The unit must only be connected to a
230 - 240V ac supply.
1.1 The electrical rating of the unit is shown on
the rating label (fig.2) within the unit.
2
Before making any sort of electrical
connection within the installation, make
sure that no terminal is live. If in any doubt,
switch off the whole installation at the
consumer unit.
3
The 7kW rated handwash must be
connected to its own independent electrical
circuit. IT MUST NOT be connected to
a ring main, spur, socket outlet, lighting
circuit or cooker circuit.
The 3kW rated handwash can be connected
to a ring main via a 13A fused spur.
3.1
The electrical supply must be adequate for
the loading of the unit and existing circuits.
4
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 fuse or miniature circuit breaker
(MCB) necessary for the handwash (fig.3).
4.1
If your consumer unit has a rating below
80A or if there is no spare fuse way, then
the installation will not be straight forward
and may require a new consumer unit
serving the house or just the handwash/
shower.
5
For close circuit protection DO NOT use a
rewireable fuse. Instead use a suitably rated
MCB or cartridge fuse (see table A).
5.1
A 30mA residual current device (RCD) must
be installed in all UK electric circuits. This
may be part of the consumer unit or a
separate unit.
WARNING!
THIS APPLIANCE MUST BE EARTHED
