5.3 Choice of location
The product must be mounted on a flat surface,
which covers the full width and length of the
backplate. It is important that the wall surface is flat
otherwise difficulty may be encountered when fitting
the cover.
Ensure that the product is positioned over the basin,
if the PRD operates, water will eject from the bottom
of the product.
The outlet of the product acts as a vent and MUST
NOT be connected to any form of outlet flow control,
or any other fitting not recommended by the
manufacturer.
WARNING
DO NOT fit the product to the wall and
tile up to the case. It must be fitted on to
a finished flat and even wall surface. This
allows removal for servicing.
Position the product above the basin so that the
spray will be contained within the basin and at a
convenient height for hand washing see figure 7
below.

Fuses do not give personal protection against electric
shock. To enhance electrical safety a 30mA residual
current device (RCD) should be installed in all electric
handwash circuits. This may be part of the consumer
unit, or a separate unit.
Ensure that all terminal block connections are
sufficiently tight.
Switch off the product immediately and isolate if
water ceases to flow during use.
Other electrical equipment e.g. extractor fans, must
not be connected to the product or its supply circuit.
To obtain full advantage of the power provided by the
product, use the shortest cable route possible from
the consumer unit to the product.
If your consumer unit has a rating below 80A, or if
there is no spare fuse way, then the installation will not
be straightforward and may require a new consumer
unit. A qualified electrician should install the new
consumer unit. It may be necessary to contact your
electrical supplier to upgrade your supply.
CAUTION
To enhance electrical safety a 30mA
residual current device (RCD) should be
installed in all electric handwash circuits.
This may be part of the consumer
unit or a separate unit. DO NOT use a
rewireable fuse, instead use a suitably
rated miniature circuit breaker (MCB)
or cartridge fuse. The handwash must
be connected to its own independent
electrical circuit.
