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.

WARNING:
THIS HANDWASH MUST BE
EARTHED.
The electrical installation must be in accordance
with the current BS.7671 (IET Wiring
Regulations) and ‘Part P’of the Building
Regulations and/or local regulations
1. The handwash unit is designed for a single
phase AC electrical supply.
2. Use 3-Core 1.5mm² double insulated cable.
The cable can be surface clipped, hidden or via
conduit.
2. The incoming cable access to the handwash
unit must be via the two bottom, the top, or
rear channels provided in the backplate (fig.C)
3. Cut back cable (fig.E).
Connect cable to terminal block making sure
that all the retaining screws are VERY TIGHT
and that no cable insulation is trapped
under the screws.
4. Ensure the cable clamp is used to secure the
cable into position.
WARNING:
FAILURE TO COMPLY WITH THESE
INSTRUCTIONS COULD RESULT IN
FAILURE OF THE TERMINAL BLOCK
IMPORTANT: Fitting the swivel arm must
precede fitting the front cover
1. Ensure the rubber ‘O’-ring is located fully on
the stainless steel pipe.
2. Slide the plastic retainer over the ‘teeth’ of the
outlet until they ‘click’ into position (fig.F).

It is necessary to engage the central
sensor lens in the correct position on the
flow valve spindle before the front cover is
finally located and secured.
1. Ensure the 2 x backplate fixing screws are
fully tightened (fig.B).
2. Ensure that the flow valve spindle and the
central sensor lens are correctly aligned
(fig.H).
Refit front cover with slot in horizontal
position, and using a coin or another suitable
implement, turn the central sensor lens
anti-clockwise until resistance is felt.
Do not use excessive force.
Remove the front cover and turn the central
sensor lens anti-clockwise to its end-stop.
Do not use excessive force.
This will ensure a fast fill up of the handwash.
3. Refit the front cover with the 3 x fixing screws
take care to ensure that internal components
especially the PCB are not damaged (fig.G).
1. Switch on the mains electrical supply at the
isolating switch.
2. Ensure the water supply is fully on at the
mains and the isolating service valve (if fitted)
is fully open.
3. Using a coin or another suitable implement,
turn the central sensor lens fully
anti-clockwise.
4. Pass your hand in front of the central sensor
lens to turn the handwash on.
The ‘Power' LED indicator will illuminate when
the unit is running.
5. Check that the water flows freely from the
handwash within a few seconds.
The water from the patented ‘Vortex’
sprayhead will be at full force and at a cool
temperature.
Check that water is not leaking from the
bottom of the case.
6. Using a coin or another suitable implement,
turn the central sensor lens slowly clockwise.
This will gradually reduce the water flow.
Check that the water gets warmer,
Turn anti-clockwise and check the water
gets cooler.
Wait a few moments for the temperature
of the water to stabilise.
NOTE: When the water temperature is
changed the flow rate alters.
7. Turn the central sensor lens so that the slot is
in the horizontal position.
1. The mains electricity and water supply should
normally be left on.
The flow of the water is controlled by a tap,
which is incorporated inside the unit.
2. To operate the handwash, simply pass your
hand in front of the central sensor lens,
it is also turned off the same way (fig.I).
The handwash will also automatically turn off
after approximately 40 seconds (fig.I).
This will, in the majority of cases, provide a
suitable temperature for washing hands.
However, in extreme conditions,
i.e. mid-winter or mid-summer, the water
temperature can be adjusted to suit.
3a. If the water is too hot,
then increase the water flow by, turning
the central sensor lens anti-clockwise
Wait a few moments for the
temperature of the water to stabilise.
Repeat turning anti-clockwise until you get
the water temperature of your liking.

3b. If the water is too cold,
then decrease the water flow by, turning
the central sensor lens clockwise,
and continue as necessary until you get the
water temperature of your liking.
The final adjustment may be anywhere on
the scale.
3c. Basically turning the central sensor lens
clockwise increases water temperature
anti-clockwise decreases the temperature
Wait a few moments for the
temperature of the water to stabilise.
4. The LED indicator on the front of the
handwash shows when the unit is operating.
5. When you have finished handwashing,
simply pass your hand in front of the central
sensor lens (fig.I).
6. The handwash will also automatically turn off
after approximately 40 seconds (fig.I).
