`
IMPORTANT - INSTALLATION
TO BE CARRIED OUT BY A
COMPETENT INSTALLER
Electrical requirements
The installation supply cable and circuit protection must conform to BS 7671.
Before making any sort of electrical connection, ensure that no terminal within the circuit is live. If in any doubt SWITCH OFF the whole installation at the consumer unit.
The product must only be connected to a 230-240V ac supply.
The earthing and protective conductor arrangement within the property, in particular the supplementary bonding in the room containing the product, must comply with BS 7671.
Ensure that the supply cable and fuse are sufficient for the rated input of your unit. Please refer to the rating label within the product.
A minimum heat resistance cable size of 1.5mm² should be used.
The product can be connected in two different ways:
`
Via a fused and switched connection unit taken as a spur from a 13amp ring main.
`
As a separate circuit taken directly from a spare way in a consumer unit.
In each case a double pole isolating switch having a contact separation of at least 3mm in each pole, and a minimum rating of 13amp must be incorporated in the wiring of the appliance.
Double pole isolating switch: pull cord or wall mounted in accordance with IEE regulations

Figure 6 – schematic of typical electrical layout
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.
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.
The control knob is an integral part of the cover - do not attempt to remove it.
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.
