INTRODUCTION
This book contains all the necessary fitting and
operating instructions for your mixer shower. Please
read them carefully and read through the whole of
this book before beginning your installation.
The shower installation must be carried out by a
suitably competent person and in sequence of this
instruction book.
Care taken during the installation will give a long and
trouble free life from your mixer shower.
SITE REQUIREMENTS
The installation must be in accordance with water
supply (water fittings) regulation 1999 and/or local
Bylaws.

This mixer shower is designed for high pressure
systems found in the UK, but can be installed with
low pressure gravity water systems with reduced
flow rates.
For effective operation of the internal seals, the
maximum static pressure must not be exceeded.
NOTE: Valves operating outside these conditions
cannot be guaranteed by the NSF Certification to
operate as Type 2 valves.
A stored water temperature of 60°C is considered
sufficient to meet all normal requirements and will
minimise the effects of scale in hard water areas.
Pressure reducing valve
On sites where the running pressure is above 5 bar,
the use of a suitably sized pressure reducing valve
fitted in the cold mains supply pipe work can provide
nominally equal pressures at the mixer shower.
Water minimum flow rate
For best performance within the specified running
pressure range a minimum flow of 8 litres per minute
should be available to both inlets.
Water temperature adjustment and thermal
safety
The mixed water temperature can be adjusted from
cold through to a top limit which must
be preset during installation with full anti-scald
protection throughout the range (35°C to 40°C)
providing the hot water temperature at the inlet
remains 10°C above the outlet temperature.
Should there be a loss of flow to either incoming
supply then- water from the shower will stop or be
reduced until both supplies are restored.
SAFETY WARNINGS
a. DO NOT choose a position where the shower
could become frozen.
b. DO NOT connect this mixer shower to any
form of tap or fitting not recommended by the
manufacturer.
c. DO NOT allow the inlet pressure or flow rates
to operate outside the guidelines laid out in ‘site
requirements’.
d. DO NOT connect the mixer shower to a
gravity hot supply and a mains cold supply (or
vice versa).
APPROVALS
This mixer valve has the following approvals
•WRAS
•TMV2 (BS EN 1111)
Designation: HP-S (high pressure shower only)
On pressures above 0.5 bar.

PLUMBING REQUIREMENTS
DO NOT use jointing compounds on any pipe
fittings for the installation,
DO NOT solder fittings near the mixer unit
as heat can transfer along the pipework and damage
the mixer valve.
DO NOT subject the unit to a water temperature
above 80°C during installation, use, maintenance or
disinfection.
IMPORTANT:
•The layout and sizing of pipework MUST be
such that nominally equal inlet supply pressures
are achieved and the effects of other draw-offs
are minimised.
•The pipe-work should be installed such
that other taps and appliances being operated
elsewhere on the premises do not significantly
affect the flow
•When connecting pipe-work avoid using tight 90°
elbows; swept or formed bends will give the best
performance.
•The hot water pipe entry MUST be made to the
left-hand side inlet, marked HOT, ‘H’ or with a
red/orange label.
•Suitable isolating valves (complying with Water
Regulations and Bylaws) MUST be fitted on the
hot and cold water supplies
to the shower as an independent means
of isolating the water supplies should
maintenance or servicing be necessary position as
close as is practicable to the water supply inlets
of the mixer shower.
•It is preferable to flush the pipe-work to clear the
system of debris and check for leaks before
connecting to the mixer.
•The mixer inlets contain removable filters that
may become blocked if debris is not flushed
through before fitting.
(Commercial applications)
•It is recommended that for all commercial
applications, easily accessible, in-line filters are
used to aid maintenance.
Hard water areas
a. If it is intended to operate the shower
in areas of hard water (above 200-ppm
temporary hardness), a scale inhibitor may have
to be fitted. For advice on the scale inhibitor,
please contact Customer Service.
b. For best performance the showerhead MUST be
regularly cleaned to remove scale and debris.
WATER SYSTEM
REQUIREMENTS
This mixer shower is suitable for:
•Gravity water systems
•Pumped gravity systems.
•Fully modulating type combination boilers
•Multi-point hot water heaters.
•Thermal storage,
•Unvented systems
When installing this mixer with a combination or
multi-point boiler, it may be necessary to install flow
regulation.
Check that the appliance is capable of delivering hot
water at a minimum switch-on flow rate
of 3 litres per minute. At flow rates between 3 and 8
litres per minute, the appliance MUST be capable of
raising the water temperature to 52°C (minimum).
Water temperature at the inlet of the mixer valve
MUST remain relatively constant when flow rate
adjustments are made (refer to the appliance-
operating manual to confirm compatibility with this
mixer shower).
Where thermal store systems and instantaneous gas
water heaters are used, if excessive draw-off takes
place, the appliance may not be able to maintain an
adequate output temperature.
This could result in the shower temperature
becoming noticeably cooler.
Flow regulators can be fitted with high-pressure
water systems to reduce flow rate and assist
economy.
The hot supply temperature MUST remain a
minimum of 10°C hotter than the required blend
temperature for optimum performance.

TYPICAL DOMESTIC
INSTALLATIONS
Domestic gravity fed systems (fig.2)
The shower control MUST be fed from a cold water
cistern and hot water cylinder providing nominally
equal pressures. There must be a minimum of one
metre head of water. The minimum head distance is
measured from the base of the cold water cistern to
top of the showerhead.
If valves are gravity fed then supply pressure should
be verified to ensure conditions of use are
appropriate for the valve.
Pumped gravity fed systems (fig.3)
The shower control MUST be fed from a cold water
cistern and hot water cylinder providing nominally
equal pressures.
The mixer unit may be used with a gravity fed system
with a pump to boost pressures as shown; please
refer to the pump installation guide to establish the
minimum head requirements for automatic operation
of the pump

Instantaneous gas-heated systems, e.g.
combination boilers (fig.4)
The shower control MUST be installed with a multi-
point gas water heater or combination boiler of a
fully modulating design (i.e.
to maintain relatively stable hot water temperatures).
A drop tight pressure reducing valve MUST
be fitted if the supply pressures exceed 5 bar running.
An expansion vessel may be fitted, and regularly
maintained, to prevent the shower mixer
being damaged by excess pressures. This may already
be installed within the boiler (check with
manufacturer) and is in addition to the normally
larger central heating expansion vessel.
Unvented mains pressure systems (fig.5)
The shower control can be installed with an
unvented, stored hot water cylinder.
For systems with no cold water take off after the
appliance reducing valve, it will be necessary to fit an
additional drop tight pressure-reducing valve when
the mains pressure is over 5 bar. The drop tight
pressure reducing valve must be set at the same value
as the unvented package pressure reducing valve.
Note: An additional expansion vessel may be
required if a second pressure-reducing valve is
installed. This does not apply to packages with a
cold take off after the pressure-reducing valve to
the cylinder.

pressures exceed 5 bar running.
An expansion vessel MUST be fitted and regularly
maintained to ensure the unit is not damaged by
excess pressures. This may already be installed
externally or internally within
the thermal store (check with thermal store
manufacturer).

INSTALLATION
Preparing the mixer valve
Check the contents to make sure all parts are
present.
Before starting the mixer installation, make sure all
the openings on the valve are carefully covered to
stop ingress of any debris, etc. while routing the
supply pipework.
The shower valve is suitable for built-in installation
in:
•a solid wall,
•a stud partition wall
•dry lined wall
•or fixing to a shower cubicle or panel.

Siting of the shower and accessories
Refer to (fig.7) for correct siting of the shower.
The mixer valve should be positioned, as detailed,
with all controls within comfortable reach of the
user.
The accessories (showerhead, riser rail and/or fixed
showerhead) can be positioned above or to either
side of the shower, refer to (fig.7).
Supply pipe work
Complete the pipework to the shower area having
decided on the position of the shower and direction
of pipe entry (for example rising, falling or rear
entry)
The hot and cold water pipes should not
be permanently attached to the wall within one
metre of the valve, before installation is complete, to
allow for final adjustment of the valve position.
Rear entry supplies
Using a spirit level, mark the route of incoming hot
and cold water supply pipes.
NOTE: The distance between centres will be
determined by the fittings used (fig.8).

BUILT-IN FITTING
The following are typical thicknesses and are
given as a guide only:
Tile 6 − 10mm
Adhesive 2 − 3mm
Plasterboard 9.5 − 12.5mm
Plaster finish 2 − 3mm
Maximum tile thickness to be 10mm.
When installing into a stud partition or other hollow
wall structure, the installer may wish to consider
building rear supports or other options for fitting
the mounting plate. Such options are beyond the
scope of this guide.
Use the cover plate or tiling shroud (if supplied) as
a template when cutting the opening for installing
the shower into a solid wall, stud partition or hollow
wall structure.
The building-in depth for the mounting plate is given
in (fig.9) from the plaster finish but this is
dependent upon tile and adhesive thicknesses.
The inlet elbows allow for either rising, falling or
rear entry hot and cold water supplies.
NOTE: To ease future requirements for cleaning
and maintenance of the unit, it is advisable to
route both the incoming and outgoing pipework
from the same direction. Access to the integral
strainers will also be improved with this layout.
Installation in a solid wall
•Decide on the shower position and determine
whether the hot and cold water supplies will
enter the shower from top (falling) or bottom
(rising) or rear.
•As a guide for the size of hole, it should be large
enough to accept the valve complete with the
inlet and outlet fittings and also allow access for
connection to the pipework.
•Remove the plaster and brickwork to the
required depth and chase out any additional areas
of the wall to give access to the pipework to and
from the valve plus any outlet fittings. Note that
the valve body requires a deeper recess than the
inlet and outlet fittings.
