DIGITAL WATER CONTROL AT YOUR FINGERTIPS
Important and safety information
Please read these instructions carefully before starting installation and keep in a
safe place for future reference.
This Installation Guide contains instructions
for the correct connection of the Solo product.
The warranty will be invalidated if the product
is not installed according to these instructions.
Crosswater accepts no liability for loss or
damage resulting from installation or use of the
product that is not in accordance with these
instructions.
All Crosswater valves are mixed flow
products, which, for optimum performance,
require hot and cold supplies to be reasonably
balanced, with no more than 0.5bar pressure
dierence between them.
This product MUST be installed by a competent
person in accordance with all current relevant
statutes and regulations, including building
regulations and the Water Supply (Water
Fittings) Regulations 1999 (together the Water
Supply Regulations.)
All showers requiring an electrical connection
MUST be installed by a qualified person
following the latest revision of BS 7671 (Wiring
Regulations) and certified to current building
regulations. Before any electrical connections
are made, the electricity supply must be turned
o at the mains switch. All electrical installation
must be carried out only by a qualified person.
We recommend that the temperature of the
shower hot water supply should not exceed
65°C.
The processor is supplied factory pre-set at
a maximum temperature of 42°C, in line with
European Standards. The maximum temperature
is fully adjustable to suit the site conditions.
Important: The processor must be installed
in an accessible location for servicing
and maintenance (and no warranty claim
can be considered or liability accepted
by Crosswater if lack of accessibility has
prevented maintenance).
The processor must not be installed in situations
where either the ambient temperature is likely to
exceed 40°C or where freezing may occur.
The user controls must not be installed in
situations where the ambient temperature is likely
to fall below 5°C or rise above 70°C.
The minimum depth of wall required to fit the
control fixing brackets is 70mm (35mm with the
bracket cut down).
Cables mounted on surfaces must be protected
by a suitable approved conduit. This applies
even in a loft, where there may be a risk of
damage by vermin.
Cables that are chased into walls must also be
protected by a conduit or sheathing to allow
removal for service and maintenance.
The power lead must not be replaced by anyone
other than the manufacturer or its accredited
agent.
The user control operates from a low voltage
source.

Important and safety information - continued
Please check for hidden pipes or cables before
drilling any holes.
The Solo is suitable for domestic or
commercial use.
This product is supplied with a 5 year warranty.
This product is not intended for use by children
or persons with reduced physical or mental
capabilities, and should not be used by such
persons without appropriate instruction and
supervision.
WARNING
CONTINUOUSLY TURNING THE
CONTROL WHEEL IN THE CLOCKWISE
DIRECTION MAY OVERRIDE THE
PRE-SET MAXIMUM TEMPERATURE,
RESULTING IN A RISK OF SCALDING.
ALWAYS TAKE CARE WHEN OPERATING
THE CONTROL WHEEL, AND DO NOT
LEAVE CHILDREN UNATTENDED
WHILST THE PRODUCT IS IN
OPERATION.
Pipe sizing
To reduce pressure losses and help maintain
flow rate, 22mm pipework should be used on
the inlets and reduced to 15mm as close to the
processor as possible, and elbows should be
kept to a minimum.
Pipe runs on both inlet and outlet should be as
short as possible to avoid reduction of flow rate
at the shower head.
If 15mm pipe is used, copper pipe should be
used rather than plastic as there is less resistance
to water flowing through.
All copper pipework must be cross-bonded and
connected to an earthing point.
Flushing
The working parts of this unit may be corroded
if left in contact with some modern fluxes, which
can be extremely corrosive. After completing
soldering the pipework should be thoroughly
flushed out in accordance with the Water Supply
Regulations prior to connection of the product.
After installation
Important: Once powered up, the control must
be programmed within one hour following the
‘Activation set-up’ section in the Operation
and care guide. This will set the maximum
temperatures, maximum run time, hygiene
intervals and ambient light.
Please familiarise the end user with how the
Crosswater Digital products work.
In the event of any warranty claims, all certificates
of the registered electricians and plumbers must
be provided to confirm that the product has
been fitted in accordance with the Water Supply
Regulations.

Flow performance
The Flow rate is depending on Dynamic water pressure of supply system to the processor.
Water pressure -recommended
MP minimum 0.5 bar
HP1 minimum 1 bar
HP2 minimum 2 bar
HP3 minimum 3 bar
HP4 minimum 4 bar
All products marked LP (Low pressure) and
MP (Medium pressure) are also suitable for HP
(High pressure) systems.
Please note: This product must work from a
minimum water pressure of 05.bar and above.
Please note: The flow chart is measured open
ended as the outlets have no restrictions.

Fitting the optional Basin mixer wall spout
Remember to turn o the mains water supply before connecting to any existing pipe work.
Install the Solo control following steps 1 - 7 (pages 9 - 13).
Prepare the wall to take the mixer tap wall spout, a 20mm diameter hole is required.
Connect the outlet from the processor to the wall fitting (not supplied). The spout has a ½” BSP
male thread that can be screwed directly into the wall fitting.
Finally pass the spout flange over the spout tube to cover the hole made in the tiles/wall.

Step 1 - Attaching the control brackets
Install the control bracket following steps 1 - 2 (pages 9 - 10).
Prepare the wall to take the mixer tap wall spout, a 20mm diameter hole is required.
The spout has a ½” BSP male thread that can be screwed directly into the wall fitting.
If using the trim plate, the hole centres of the control and mixer wall spout MUST be 102mm
apart.
Finish the wall by tiling etc. The control requires a 55mm diameter hole and the mixer wall spout
needs a 40mm diameter hole drilled in the tile etc to finish.

the adaptor ring must be flush with the rim of the trim plate ring. Fix through the adaptor ring
holes into the bracket collar using the 15mm screws.
Peel o the backing paper from the adhesive seal on the back of the trim plate. Position and fix the
trim plate in position on the wall.
Step 2
Draw a line around the bracket collar, flush with the wall. Note: The collar must be flush with the
tiled wall.
Carefully cut down the bracket collar as marked. Note: Feeding a string or wire through the
bracket and conduit will make it easier to pull the cable through to the processor.
