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 mixer 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
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.
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.
SAFETY WARNINGS
DO NOT allow the inlet pressure or ow rates
to operate outside the guidelines laid out in site
requirements.

PLUMBING REQUIREMENTS
DO NOT choose a position where the mixer
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 mixer shower
as heat can transfer along the pipework and
damage the mixer shower.
DO NOT subject the mixer 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 mixer 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 the Triton Customer
Experience team.
b. For best performance the shower head MUST
be regularly cleaned to remove scale and
debris.
WATER SYSTEM REQUIREMENTS
This mixer shower is suitable for:
• Pumped gravity systems
• Fully modulating type combination boilers
• Multi-point hot water heaters
• Thermal storage
• Unvented systems
When installing this mixer 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
shower 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.
The hot supply temperature MUST remain a
minimum of 10°C hotter than the required blend
temperature for optimum performance.

TYPICAL DOMESTIC INSTALLATIONS
Pumped Gravity Fed Systems (g.1)
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.2)
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 shower mixer being
damaged by excess pressures. This may already
be installed within the boiler (check with the
manufacturer) and is in addition to the normally
larger central heating expansion vessel.

Unvented Mains Pressure Systems
(g.3)
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.
Mains Pressurised Thermal Store Systems
(g.4)
Packages of this type, tted with a tempering
valve (blender valve) can be used. A drop tight
pressure reducing valve MUST be tted if the
supply pressures exceed 5 bar running.
An expansion vessel MUST be tted 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
INSTALLING THE WALL BRACKETS
PRIMARY CONSIDERATIONS
Please consider the following points before
beginning the installation:
• The brackets must be mounted onto a surface
that is both solid and strong enough to
support the final assembly of brackets and bar
mixer.
• The connectors can be used with either
15mm copper or plastic pipework.
• The pipes that enter the brackets should be
cut using a suitable pipe cutter and deburred.
IMPORTANT: The bar mixer brackets are
designed to be mounted onto a solid structure.
If installing to a stud partition wall, dry lined
wall or similar, it is recommended that the
brackets are secured to the studs or noggins. In
this case, the pipework to the brackets should
pass through the support studs or noggins via a
suitably sized hole (fig.6).
Decide upon the mounting position of the
brackets on the wall and mark the centres.
Check the mounting marks are level and that the
distance between them is equal to the distance
between the bar mixer inlet centres (fig.7).
Mark the route of the pipework to the brackets.
Remove the plaster and brickwork (or
plasterboard) to the depth required and chase
out additional areas of the wall to allow for the
incoming pipework. Make sure that enough solid
structure of wall remains around the chasing to
accommodate the mounting plate wall plugs
and screws (fig.8).

Complete the pipework to the bracket mounting
points. Leave an excess of pipe protruding out
of the wall of approximately 60mm as measured
from the face of the finished wall or tiles (fig.9).
Flush the pipework through to remove any
debris.
Check for leaks and remedy as necessary.
Make good the wall, tiled surfaces MUST be
level, check with spirit level.
Ensure the pipes exiting the wall are free and
can move in and out of the wall by a maximum
distance of 4mm (fig.10).
Push each pipe into the wall until it stops against
the depth of chasing. Measure 21mm to 25mm
from the face of the finished wall or tiles and
mark the pipe.
Using a pipe cutter, cut the pipe and deburr.
IMPORTANT: When the pipework is at rest
against the depth of chasing the length of pipe
protruding from the wall should be between
25mm MAXIMUM and 21mm MINIMUM from
the face of the finished wall or tiles (fig.11).
Make sure the outer surface of the pipes is clean
and free of any debris or damage. Clean the
surface if necessary.
Mark the positions of the wall bracket holes and
drill the wall/tiles to suit.
Slide the wall bracket over the pipework and
securely fix to the wall.
Slide the olive over the pipework and push down
until it meets the wall bracket. Ensure the olive
is clear of the end of the pipework and the pipe
does not enter too far into the connector outlet
and prevent the plastic seal fitting correctly.
Screw the nut onto the wall bracket and tighten
until the olive is compressed onto the pipework.

FITTING THE RISER/FIXED HEAD RAIL
Temporariliy fit the riser rail to the mixer shower
by gently pushing and rotating into place - adding
a little grease can help to ease the rail into place
(g.16).
Mark the centre hole for the wall bracket.
Remove the riser and drill and plug the wall.
An appropriate drill bit should be used. If the wall
is brick, plasterboard or a soft building block, use
appropriate wall plugs and screws should be used.
Secure the bracket to the wall (g.17).
Ret the rail.
IMPORTANT: When installing the wall
bracket, care must be taken not to damage the
decorative surface nish.
Triton recommend the use of an appropriate tool
with a soft cloth, or similar, placed between the
product and the tool (g18).

LEAK TESTING
Screw the nut end the of the hose to the bottom
outlet on the mixer shower, making sure that the
sealing washer is in place, and direct it to waste
(g.19).
Open the isolating valves to the mixer shower
and check for leaks. Remedy any leaks found.
FITTING THE SHOWER HEAD
Screw the conical end of the hose to the shower
head then locate the shower head into the slider.
Screw the fixed head to the riser/fixed head rail.
Make sure the sealing washer is in place and
screw tight to seal the joint.

COMMISSIONING
Start the water ow by rotating the ow control
(g.20).
Make sure that the hot and cold water supplies
are fully open and at (or near to) their design
temperature and pressures, and are within the
requirements stated in the site requirements.
Make sure the temperature control is at the
maximum temperature setting. Allow the mixer
shower to run at this maximum temperature
setting until the water temperature has stabilised.
Rotate the temperature control until your desired
showering temperature is reached.
IMPORTANT
The temperature adjustment range must be
checked to guarantee user safety.
Rotate the temperature control checking
the minimum and maximum showering
temperatatures; ADJUST THE MAXIMUM
TEMPERATURE STOP SETTING on page 14 if
required.
The following is recommended for domestic
installations but must be carried out for
commercial installation: 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.

Important
The mixer shower has a temperature stop
to prevent accidental rotation to higher
temperatures. This is adjustable to provide a
maximum temperature of 35°C – 46°C.
The mixed water temperature can be adjusted
from cold through to a top limit (which can
be pre-set during installation – factory set
at approximately 38°C) with full anti-scald
protection throughout the range.
Should there be a loss of ow to either incoming
supply then water from the mixer shower will
stop or be reduced until both supplies are
restored.
Recommended Outlet Temperatures
The BuildCert TMV scheme recommends a
maximum mixed water outlet temperatures of
41°C for showers.
The mixed water temperatures must never
exceed 46°C.
The British Burns Association recommends 37°C
to 37.5°C as a comfortable bathing temperature
for children.
WARNINGS
Exposed metal surfaces may become hot during
use.
Fig.23
Adjusting the Maximum Temperature
Override Setting
Remove the temperature control by removing
the end cap and unscrewing the retaining screw
(g.23).
Turn the flow control to full flow. With a
steady flow running, adjust the temperature
valve spindle until the temperature is about
38°C.
When you are satised with the temperature
turn the ow control off. Ret the temperature
control. Secure with the screw and replace the
end cap.

Cleaning
The manufacturer recommends that all products
are cleaned using warm, soapy water.
Do not use abrasive or aggressive chemical
cleaning products as this may affect the product
surface nish and invalidate your guarantee.
Cleaning the Filters
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 the lter from the inlets.
Wash thoroughly under running water to remove all
debris using a suitable brush. Ret and reassemble
the shower onto the inlet ttings.
MAINTENANCE
The following maintenance procedure is
recommended for domestic installations but must
be carried out for commercial installations.
Maintenance of the mixer shower is required to
give continued performance after installation and
that it continues to provide scald prevention.
Note: A thermostatic mixer shower 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 mixer shower 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.
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
the contact details on page 15 for spare parts.
