WARNING
3.1 The handwash must not be positioned where it will be subjected to freezing
conditions.
WATER REQUIREMENTS
3.2 The installation must be in accordance with Water Regulations. To ensure
activation of the heating elements, the handwash must be connected to a mains
water supply with a minimum running pressure of 0.1 MPa (1 bar) and a
maximum static pressure of 0.7 MPa (7 bar). If static pressure exceeds
0.7MPa (7 bar) t a pressure reducing valve to avoid damaging the appliance. If
in doubt, the pressure should be checked taking account of other services from
the same water supply which could cause the pressure to fall below the
minimum. The water supply can also be taken from a cold water storage
cistern provided there is a minimum head of 10m above the appliance.
3.3 If the handwash is operated outside of the stated pressure parameters, it may
not be possible to achieve optimum performance from the appliance
throughout the year.

COMPETENT INSTALLER
3.5 The installation supply cable and circuit protection must conform to
BS 7671.
3.6 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.
3.7 The handwash must only be connected to a 230-240V ac supply.
3.8 The earthing and protective conductor arrangement within the property, in
particular the supplementary bonding in the room containing the handwash,
must comply with BS 7671.
3.9 Ensure that the supply cable and fuse are sufcient for the rated input of your
appliance. Please refer to the rating label within the appliance.
3.10 A minimum heat resistant cable size of 1.5mm² should be used. The
handwash can be connected in two different ways:
1. Via a fused and switched connection unit taken as a spur from a 13amp ring
main.
2. 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.

3.11 To obtain full advantage of the power provided by the handwash, use the
shortest cable route possible from the consumer unit to the handwash.
3.12 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 qualied electrician should install the new consumer unit. It
may be necessary to contact your electrical supplier to upgrade your supply.
CAUTION
3.13 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.
