INTRODUCTION
This book contains all the necessary tting 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 ttings) 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 ow rates.
For effective operation of the internal seals, the
maximum static pressure must not be exceeded.
A stored water temperature of 60°C is
considered sufcient to meet all normal
requirements and will minimise the effects of
scale in hard water areas.
Valves operating outside these conditions of
use cannot be guaranteed to operate as Type 2
valves.
Pressure Reducing Valve
On sites where the running pressure is above 5
bar, the use of a suitably sized pressure reducing
valve tted in the cold mains supply pipework
can provide nominally equal pressures at the
mixer shower.
Water Minimum Flow Rate
For best performance within the specied running
pressure range a minimum ow 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 ow to either incoming
supply then water from the shower will stop or
be reduced until both supplies are restored.
SAFETY WARNINGS
DO NOT allow the inlet pressure or ow rates
to operate outside the guidelines laid out in Site
Requirements.
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

Mini Exposed Sequential Thermostatic Mixer Shower

PLUMBING REQUIREMENTS
DO NOT choose a position where the shower
could become frozen.
DO NOT connect to any form of tap or fitting
not recommended by the manufacturer.
DO NOT use jointing compounds on any pipe
ttings for the installation.
DO NOT solder ttings near the shower as heat
can transfer along the pipework and damage the
shower.
DO NOT subject the shower 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 pipework should be installed such
that other taps and appliances being
operated elsewhere on the premises do not
signicantly affect the ow
• When connecting pipework 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
tted 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. If this
isolator is tted in a loft space, the loft must
have a xed access ladder and be boarded,
with appropriate lighting from the access
point to the isolator.
• Flush pipework to clear the system of debris
and check for leaks before connecting to the
mixer.
Commercial Applications
For commercial applications in-line lters are
recommended.
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 tted. For advice on the scale
inhibitor, please contact our Triton Customer
Experience team.
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 shower with a combination
or multi-point boiler, it may be necessary to
install ow regulation.
Check that the appliance is capable of delivering
hot water at a minimum switch-on ow rate
of 3 litres per minute. At ow 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 ow rate
adjustments are made - refer to the appliance
operating manual to conrm 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 tted with high-pressure
water systems to reduce ow 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 (g.3)
The mixer shower 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
shower head.
If valves are gravity fed then supply pressure
should be veried to ensure conditions of use are
appropriate for the valve.
Pumped Gravity Fed Systems (g.4)
The mixer shower MUST be fed from a cold
water cistern and hot water cylinder providing
nominally equal pressures.
The mixer shower 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 (g.5)
The mixer shower 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 tted if the supply pressures exceed 5 bar
running.
An expansion vessel MAY be tted and regularly
maintained, to prevent the mixer shower
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 (g.6)
The mixer shower 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
t 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.

INSTALLATION
Preparing the Shower
Check the contents to make sure all parts are
present.
Before starting the installation, ensure all the
openings on the shower are carefully covered to
stop ingress of any debris, etc. while routing the
supply pipework.
The mixer shower can be installed in the
following applications:
• a solid wall
• a stud partition wall
• dry lined wall
• or xing to a shower cubicle or panel
Siting of the Shower and Accessories
Refer to g.8 for correct siting of the shower.
The shower should be positioned as detailed,
with all controls within comfortable reach of the
user.
The accessories (shower head, riser rail and/or
xed shower head) can be positioned above or
to either side of the shower (g.8).
The valve must be installed in a position that
allows for easy access for future maintenance and
commissioning.
FITTING THE SHOWER
Supply Pipework
Having decided on the position of the shower
and direction of pipe entry, for example rising,
falling or rear entry, complete the pipework to
the shower area.
The hot and cold water pipes should not
be permanently attached to the wall
within one metre of the mixer shower
before installation is complete, to allow
for nal adjustment of the valve position.
For rear entry supplies, use a spirit level to mark
the route of incoming hot and cold water supply
pipes at a distance of 150mm between centres
(g.9).

Mark the position of the four locating screws for
the mounting plate, although if installing on to
a solid brick wall using two diagonal holes will
usually be enough.
Drill and plug the wall. An appropriate drill bit
should be used. If the wall is brick, plasterboard
or a soft building block, appropriate wall plugs
and screws should be fitted.
Fit the mounting plate on to the wall (g.10).
IMPORTANT: Make sure that all supply
pipework has been ushed through before
tting the mixer shower (g.11).
The inlet elbows allow for either rising, falling
or rear entry hot and cold water supplies. The
elbows have ‘O’ ring seals (g.12) to the body
and do not require PTFE tape or other means of
sealing.
Fit the trim onto the inlet water pipes followed
by the nut and olive. Connect the hot water
supply to the inlet marked HOT, ‘H’ or red/
orange label and connect the cold water supply
to the inlet marked COLD, ‘C’ or blue label
(g.13).
Tighten all compression ttings.
Tighten all the grub screws to secure the mixer to
mounting plate.
The outlet adaptor and plug can be repositioned
dependant on whether top or bottom outlet is
required. The adaptor is suitable for a 15mm
rigid pipe connection.

Flow Regulation
A ow regulator (not supplied) is used with
high-pressure water systems and may be tted
with any of the water systems listed in the Water
System Requirements section to reduce ow rate
and assist economy.
To t a ow regulator (exible hose connection)
unscrew the outlet adaptor. Place the ow
regulator into the rigid pipe connection end;
please note the ow regulator is only designed to
work in one direction (g.14).
The ow regulator for 15mm rigid pipe must be
tted into the shower head.
LEAK TESTING
Direct the outlet of the mixer to waste. Open the
isolating valves to the shower and check for leaks.
Remedy any leaks found.

COMMISSIONING
NOTE: The maximum temperature should be
checked on site to guarantee user safety.
After tting the controls, start the water ow by
rotating the control knob.
Make sure that both the hot and cold water
supplies are fully open and at (or near to) their
design temperature and pressures and are
within the requirements as stated in the Site
Requiriements section.
Make sure the temperature control is at the
maximum temperature setting - rotated fully
anti-clockwise.
Allow the shower to run at the maximum
temperature setting until the water temperature
has stabilised. Rotate the temperature control
until your desired maximum showering
temperature is reached.
The mixer has a temperature stop to prevent
accidental rotation to higher temperatures. This
is adjustable to provide a maximum temperature
of 35°C – 40°C and should be checked on site to
guarantee user safety.
The following is recommended for domestic
installations but must be carried out for
commercial installations: Check the thermal shut
off facility of the mixer shower by performing a
thermal shut off test.
Shut off the cold supply. The ow from the mixer
shower should stop immediately or reduce to
a trickle in which case the water temperature
should be less than 43°C.
In either case there is no risk of scalding.
If, however, the temperature is above 43°C then
it is likely there is contamination in the mixer
shower stopping it from shutting off the hot
supply. In this case refer to the maintenance
section or contact Triton Customer Experience.
ANTI-SCALD PROTECTION
It is important that the mixer shower is tested
regularly to prevent the risk of scalding and
guarantee user safety. This can be carried out as
follows: with the mixer blend temperature set
at 38°C isolate the cold water supply. The outlet
ow rate will reduce to a safe level.

Mini Exposed Sequential Thermostatic Mixer Shower

ADJUSTING THE MAXIMUM
TEMPERATURE SETTING
The maximum temperature stop is factory set to
38°C, this can be adjusted during installation.
Note: Before tting the levers the
maximum temperature should be checked
on site to guarantee user safety.
The BuildCert TMV scheme recommends the
following set maximum mixed water outlet
temperatures for use in all premises:
44°C - for bath ll but see notes below.
41°C - for showers.
41°C - for washbasins.
38°C - for bidets.
The mixed water temperatures must never
exceed 46°C at terminal tting.
The British Burns Association recommends 37°
to 37.5°C as a comfortable bathing temperature
for children. In premises covered by the Care
Standards Act 2000, the maximum mixed water
outlet temperature is 43°C.
To adjust the maximum temperature setting,
remove the temperature control knob.
Allow the water to run until the temperature has
stabilised, adjust the temperature control spindle
by hand (g.17).
When the showering temperature is satisfactory
turn off the shower.

MAINTENANCE
The following maintenance procedure must
be carried out for commercial and health care
premises, but is not necessarily required for
domestic installations.
Maintenance of the shower is required to give
continued performance after installation and so
that it continues to provide scald prevention.
Note: A thermostatic mixing valve in need of
maintenance can be undetectable in normal
use and only becomes apparent when a
disruption occurs in the hot or cold water supply
temperatures or pressures.
The frequency of routine maintenance of the
internal of the valve will depend mainly on the
water supply condition. Experience of local
conditions will dictate the intervals for inspection
and in-service testing; guidance has been
given below which can be adjusted for local
requirements.
a) Initially check the lters for debris once every
three months and clean if necessary.
b) Perform a thermal shut off test every
three months, and check the maximum
temperature setting. See the Commissioning
section for the details of this test and
readjustment of the maximum temperature
setting if required.
c) If the maximum water temperature varies
by more than 2°C from the commissioned
setting then carry out the following checks
• Check the isolating valves are fully open.
• Check the internal surface for scaling.
If the body requires descaling then it should be
removed from the pipework to carry out this
work - all rubber parts must be removed before
descaling.
• Check the function of the non-return valves
NOTE: The non-return valves (NRVs) prevent
cross-ow between hot and cold supplies
under unequal pressure conditions. They are
designed for long life with no maintenance.
If these checks do not highlight the reason
for the temperature variation, then internal
components will require replacement - please see
Customer Experience contact details.
Cleaning
It is recommended that all products are cleaned
using warm, soapy water.
Do not use abrasive or aggressive chemical
cleaning products as this may damage the
product surface nish and ttings and invalidate
your guarantee.
Cleaning the Filters (g.A)
It is advised that this should be carried out by a
qualied person.
• Turn off the water supplies before starting.
• To gain access to the lters remove the unit
from the inlet ttings.
• Remove hot and cold elbows.
• Remove the retaining clip and NRV.
• Wash the lter thoroughly under running
water, use a suitable brush to remove all
debris.
• Reassemble the shower.
Disinfection
Where chlorine is used for the disinfection
of water systems all relevant guidelines and
approved codes of practice must be strictly
followed. Failure to comply with the relevant
guidelines and approved codes of practice may
invalidate your guarantee.
