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 45°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.
This appliance must be earthed.
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.

Installation instructions
Step 1 - Cutting down the control fixing bracket
To make the installation easier, we recommend that the control fixing bracket is cut down as
shown using a hacksaw.
Prepare the wall to take the control fixing bracket. The installation of the control fixing bracket
will depend on each individual situation i.e. if there is access from behind the shower.
Bracket attached from behind: a 40mm diameter hole is required.
Bracket attached from the front: a 68mm diameter hole is required.
Conduits should be used in the walls where necessary to protect the cables and allow
maintenance.
Attach the control fixing bracket using the screws supplied.

Step 6
Carefully pull the ‘front’ control wheel o the control. Feed the ‘foam seal’ onto the data cable
and onto the control body.
Feed the control data cable through the bracket. Note: Attaching a length of string or wire to the
control data cable will make it easier to pull the cable through to the processor.

Step 9
Remove the inlet connector screw, insert
the inlet connectors and re-insert the screw.
Step 11
Screw 10mm flexi hoses*(not supplied) into the hot and cold inlets, ensure the flat gaskets are
fitted between the inlet connectors and flexi hoses.
Remove the outlet connector screw, insert the outlet connector and re-insert the screw.
* The flexi hoses required are: 150mm, DN8-HF ½” FAxM10x1 (Note: without HF hoses the
flow rate is significantly lower), we can supply the flexi hoses if required.
Step 12
Step 13
Attach 15mm pipework to the outlet connector, ensure a flat gasket is fitted between the outlet
connector and flexi hose.
Note: Make sure that the pipework is perpendicular to the processor so that there is no strain
on the fittings, use pipe clips as required.
Run a pipe from the mixed water outlet on the processor through the wall to the proposed
position of the shower hose outlet etc.
Important: Flush through the pipework before connection.
Attach the 15mm hot and cold water supply connections.
Note: Do not over-tighten the brass nuts to avoid cracks.

Remove the ‘sealed wrapping’ from around the connector and connect the data cable from the
‘Control’ to the connector block in the processor. Ensure the cable locates as shown, see ‘Inside
the Processor’ on page 14.
Connect the data cable from the ‘Transformer’ to the connector block in the processor.
Ensure the cable locates as shown, see ‘Inside the Processor’ on page 14.
Step 16
Re-fit the processor cover. Plug the transformer into a power socket.
Step 17 - Control set-up
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.
