THIS APPLIANCE CAN BE USED BY CHILDREN AGED FROM 8 YEARS AND
ABOVE AND PERSONS WITH REDUCED PHYSICAL, SENSORY OR MENTAL
CAPABILITIES, OR LACK OF EXPERIENCE AND KNOWLEDGE IF THEY HAVE
BEEN GIVEN SUPERVISION OR INSTRUCTION CONCERNING USE OF THE
APPLIANCE IN A SAFE WAY AND UNDERSTAND THE HAZARDS INVOLVED.
CHILDREN SHALL NOT PLAY WITH THE APPLIANCE.
CLEANING AND USER MAINTENANCE SHALL NOT BE MADE BY CHILDREN
DO NOT SWITCH THE APPLIANCE ON IF YOU SUSPECT THE APPLIANCE
OF BEING FROZEN. WAIT UNTIL YOU ARE SURE IT HAS THAWED OUT.
Your handwash unit has been designed for
convenience, economy and safety of use,
provided that it is installed, used and
maintained in good working order and in
accordance with our instructions and
recommendations.
ALL WIRING AND INSTALLATION
MUST BE SUPERVISED BY A
SUITABLY QUALIFIED PERSON.
THIS APPLIANCE MUST BE
EARTHED.
The installation must be in accordance with
the current edition of BS.7671 (
the ‘IET Wiring
Regulations’)
and ‘Part P’ of the ‘
Building
Regulations’
in force at the time of installation.
Installations outside England and Wales must
also conform to any local regulations in effect
This appliance is intended to be permanently
connected to the fixed electrical wiring of the
mains supply with its own dedicated supply.
This appliance must
NOT
be fitted where it
may be subjected to freezing conditions.
Isolate the mains electrical and water supply
before removing the appliance front cover.
DO NOT
fit any sort of tap or control on the
appliance outlet.
Take care to avoid restricting the outlet of the
pressure relief device (fig.C).
If water is discharged from the pressure relief
device, maintenance will be required before
the appliance can be safely used.
The following points will help you have a greater
understanding of how your handwash works:
The electric heating element operates at a
constant rate.
The required water temperature is achieved
by adjusting the rate of water flow.
The higher the water flow the lower the
temperature and vice versa.
The temperature of the water supplied from
the mains can vary considerably throughout
the year from 5 to 20°C.
This means that in the winter, flow rate will be
less than in the summer to achieve the same
outlet temperature.
Your handwash is designed to work within a
range of water pressures, if the pressure falls
below the minimum pressure required, it is
likely that the pressure switch will turn off the
power to the heating element, resulting in
cold water being produced by the unit.
(see page 3 for details)

Plan your own installation carefully.
Check on the nearest and most readily accessible
rising mains water supply.
The unit should be sited so that all the spray is
contained in the sink (fig.A)
We recommend that a WRAS (Water Regulations
Advisory Scheme) listed isolating valve is fitted
into the mains cold water supply for servicing
purposes.
WARNING:
ALL WIRING AND INSTALLATION
MUST BE SUPERVISED BY A
SUITABLY QUALIFIED PERSON.
DO NOT INSTALL THIS UNIT
WHERE IT MAY BE SUBJECTED TO
FREEZING CONDITIONS.
USE ONLY THE COLD RISING
WATER MAIN SUPPLY.
DO NOT CONNECT THE HANDWASH
UNIT TO THE DOWN SERVICE FROM
A COLD WATER STORAGE TANK.
Plumbing the handwash unit must precede
making electrical connections.
The handwash unit must be connected to the
cold water supply with a minimum running
pressure of 69 kPa (0.7 bar, 10 psi) and a
maximum pressure of 690 kPa (7.0 bar, 100 psi).
Turn off the water supply at the isolating tap.
Before removing the front cover, using a coin or
another suitable implement, check that the
central sensor lens is turned fully anti-clockwise.
1. Remove the three screws securing the
handwash unit cover and remove the cover
complete with the central sensor lens.
2. Place the handwash unit on the wall and
determine the entry position of the water inlet
supply pipe.
Ø15mm copper, chrome polished or stainless
steel pipe should be used.
Ensure that there are no burrs on the pipe.
In multiple handwash installations, correct
pipe work sizes should be calculated to
maintain adequate flow to each unit.
3. Mark the location of the fixing screws through
the backplate (fig.B).
A ‘keyhole slot provided on the top fixing hole
to assist installation, and should be marked
and drilled first to take the wall plugs and
screws provided.
4. Tighten the top screw with head protruding
about 10mm from the wall and hook the
backplate over the screw head.
This allows for correct and accurate alignment
of the handwash unit before fixing the bottom
position.
You may not wish to tighten up both screws
at this stage as the holes are elongated to
allow for adjustment after other connections
have been made
5. Before completing the connection of the water
supply to the inlet of the unit, ensure you
flush out the pipework to remove all swarf and
system debris.
6. Connect the mains water supply to the inlet of
the handwash unit using the relevant Ø15mm
pipe.
Do not use excessive force when making
the connection to the unit (fig.D).
7. It is permissible to use a WRAS (Water
Regulations Advisory Scheme) approved
sealant sparingly whilst avoiding excess
finding its way into the handwash operating
parts.
WARNING:
TAKE CARE TO AVOID
RESTRICTING THE OUTLET OF THE
PRESSURE RELIEF DEVICE.
