INTRODUCTION
This book contains all the necessary tting and
operating instructions for your Triton 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 Regulations and Bylaws.
Water Pressure Requirements
Designation: HP-S
Running water pressure:
Gravity fed (LP) - 0.2 bar min.
1.0 bar max.
Mains fed (HP) - 1.0 bar min.
5.0 bar max.
Maximum static water pressure:
Gravity and mains - 10 bar
This mixer shower is designed for use with
traditional low pressure gravity water systems,
using a cold water cistern and hot water cylinder
as well as for the higher pressure systems found
in the UK up to a maximum of 5 bar running
pressure.
For effective operation of the internal seals, the
maximum static pressure must not be exceeded.
If a water supply is fed by gravity then the
supply pressure should be veried to ensure the
conditions of use are appropriate for the valve.
NOTE: TYPE 3 approval applicable only to HP
systems.
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 Requirements
Maximum hot water temperature: = 80°C
TYPE3 Recommended maximum: = 65°C
Minimum hot water temperature: = 55°C
Maximum cold water temperature: = 20°C
Minimum cold water temperature: = 5°C
Minimum temperature differential: = 10°C
The mixer shower MUST NOT be subjected to
water temperatures above 80°C.
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 cannot
be guaranteed by the scheme to operate as type
3 valves.
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
a. DO NOT choose a position where the mixer
shower could become frozen.
b. DO NOT connect this mixer shower to any
form of tap or tting not recommended by
the manufacturer.
c. DO NOT allow the inlet pressure or ow
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.

PLUMBING REQUIREMENTS
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 shower.
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 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.
• It is preferable to ush the pipework to clear
the system of debris and check for leaks
before connecting to the mixer.
• The mixer inlets contain removable lters
that may become blocked if debris is not
ushed through before tting.
Commercial Applications
• It is recommended that for all commercial
applications, easily accessible, in-line lters
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 tted. For advice on the
scale inhibitor, please contact Customer
Experience.
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:
• 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
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 take 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 COMMERCIAL INSTALLATIONS
Commercial Gravity Fed Systems
(g.2)
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.
Commercial 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.

INSTALLATION
PREPARING THE SHOWER
Check the contents to make sure all items are
present.
Before starting, make sure all of the openings on
the valve are carefully covered to stop ingress
of any debris etc, while routing the supply
pipework.
The shower is suitable for exposed installation
onto solid wall, a stud partition wall, dry lined
wall or xing to a laminate cubicle or panel.
SITING OF THE SHOWER & ACCESSORIES
Refer to g.4 for correct siting of the shower.
The mixer shower should be positioned as
detailed, with all controls within comfortable
reach of the user.

*SUPPLY PIPEWORK
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 be securely
attached within the wall or panel to support the
valve and prevent movement after installation.
Pipe tting depth should be checked in
conjunction with the information given in g.5
- a MINIMUM of 7mm of thread MUST be
available once the straight tting is secured
into the wall end tting and the cover trim has
been tted; this is to allow the mixer to be tted
correctly. Inlet pipe centres should be 150mm
apart.
*STRAIGHT FITTINGS
The supply pipes can be routed from the side,
rising, rear or falling and must end in suitable
ttings to accept the long thread connectors
(g.5).
The straight connectors can be used to connect
to ½” BSP female elbow ttings in solid wall
installations. The inlet centres on the shower
valves must be aligned horizontally and centred
to 150mm.
The hot and cold supply pipes MUST be
anchored rigidly to support the valve and stop
any movement after installation.

FITTING THE SHOWER & CONTROLS
Offer the shower valve up to the ttings.
Check that the sealing washers are in place.
Screw the unions onto the ttings.
NOTE: The mixer controls will need to be
fitted before commissioning can be carried
out.
Temperature Control
Fit the maximum temperature stop in the
orientation shown in g.8.
To fit the temperature control (right hand side),
position the temperature graphic as close to the
12 o’clock position as possible. Once in place, fit
the retaining grub screw.
Flow Control
To fit the flow control (left hand side), the flow
control cartridge needs to be turned fully
clockwise until it stops (g.9)
NOTE: The flow control graphic (styles of this
may vary) should be positioned so that it is at
the 12 o’clock position.
If fitted correctly, the graphic and flow control
should now be sitting in the designed OFF
position.
Once in place, fit the retaining grub screw.
Do not fit the levers until the commissioning
procedure has been carried out and the
temperature range checked.
LEAK TESTING
IMPORTANT: Flush out the pipework in
accordance with Water Regulations and
Bylaws.
Fit the hose to the outlet, without the shower
head tted, and direct it towards the waste
outlet.
Open the water isolating valves to the shower
and check for leaks.
If any leaks are found, rectify them before
carrying out the commissioning procedure.

COMMISSIONING (TYPE 3)
The following conforms to Department of Health (doH), Health Technical
Memorandum HTM 04-01: Supplement Performance specication D 08:
thermostatic mixing valves (healthcare premises) for when the mixer has been
installed in healthcare premises.
Important: Make sure that all supply pipework has been ushed through before
commissioning.
The maximum temperature should not exceed 41°C.
Start the water ow by rotating the ow control.
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.
Make sure the temperature control is at the maximum temperature setting.
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 41°C
and should be checked on site to guarantee user safety.
After setting the maximum temperature, turn the shower on and off several times and check the
maximum setting is correct. Record the commissioning data on the maintenance record at the
rear of this book in order for the in-service performance of the mixer valve to be assessed.
Finally, check the thermal shut off facility of the valve by performing a thermal shut off test.
Shut off the cold supply.
The ow from the 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 valve
stopping it from shutting off the hot supply. In this case refer to the maintenance section or
contact Customer Experience.
In domestic installations where D 08 specication is not required, the maximum
temperature setting should not exceed 46°C.
Temperature Adjustment Range
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.

COMMISSIONING
Start the water ow by rotating the ow control
(left hand side) anticlockwise.
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 as stated on page 2.
Make sure the temperature control (right hand
side) is at the maximum temperature setting.
Allow the shower to run at this maximum
temperature setting until the water temperature
has stabilised.
Rotate the temperature control until your desired
maximum showering temperature is reached.
NOTE: If your desired temperature is above
the maximum temperature stop limit, please
see Adjusting The Maximum Temperature
Stop Settingsection.
A nal temperature check SHOULD be made
on-site to guarantee user safety and that the
mixer falls within recommended maximum
mixed water outlet temperatures as stated in
the Receommended Outlet Tempertaures
section.

TEMPERATURE ADJUSTMENT RANGE
The mixer 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.
Recommended Outlet Temperatures
The KIWA TYPE 3 scheme recommends a
maximum mixed water outlet temperature of
41°C for showers.
The mixed water temperatures must never
exceed 46°C at terminal tting.
The British Burns Association recommends 37°C
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.
ADJUSTING THE MAXIMUM
TEMPERATURE STOP SETTING
Undo the retaining grub screw and pull the
temperature control off (g.10).
The maximum temperature stop does not need
to be removed.
Turn the flow control to full flow. With a steady
flow running, adjust the temperature spindle
until the temperature is about 38°C (g.11).
When the showering temperature is satisfactory
turn off the shower. Refit the temperature
control, making sure the graphic aligns as closely
to the to 12 o'clock as possible.

IN-SERVICE TESTING
Maintenance of the unit is required to give
continued performance after installation and 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.
Purpose
The purpose of in-service tests is to regularly
monitor and record the performance of the
thermostatic mixing valve. Deterioration in
performance can indicate the need for service
work on the valve and/or the water supplies.
Procedure
Using the same measuring equipment or
equipment to the same specication as used
in the commissioning of the valve, adjust the
temperature of the mixed water in accordance
with the manufacturer’s instructions and the
requirement of the application. Carry out the
following sequence:
a) Record the temperature of the hot and cold
water supplies.
b) Record the temperature of the mixed water
at the largest draw-off ow rate.
c) Record the temperature of the mixed water
at a smaller draw-off ow rate, which shall be
measured.
If the mixed water temperature has changed
signicantly from the previous test results
(e.g.> 1 K) 5), record the change and before
re-adjusting the mixed water temperature check
that:
a) that any in-line or integral strainers are clean,
b) any in-line or integral check valves or other
anti-back siphonage devices are in good
working order,
c) any isolating valves are fully open.
With an acceptable mixed water temperature,
complete the following procedure:
a) Record the temperature of the hot and cold
water supplies.
b) Record the temperature of the mixed water
at the largest draw-off ow rate.
c) Record the temperature of the mixed water
at a smaller draw-off ow rate, which shall be
measured.
d) Isolate the cold water supply to the
mixing valve and monitor the mixed water
temperature.
e) Record the maximum temperature achieved
as a result of (d) and the nal stabilised
temperature.
f) Record the equipment, thermometer etc.
used for the measurements.
If at step (e) the nal mixed water temperature
is greater than the values in Table 17 and /
or the maximum temperature exceeds the
corresponding value from the previous results by
more than about 2 K, the need for service work
is indicated
NOTE: In-service tests should be carried out
with a frequency, which identies a need
for service work before an unsafe water
temperature can result. In the absence of any
other instruction or guidance, the procedure
described in Annex F of D 08 may be used.
Annex F of D 08 (informative)

FREQUENCY OF IN-SERVICE TESTS
General
In the absence of any other instruction or
guidance on the means of determining the
appropriate frequency of in-service testing, the
following procedure may be used:
a) 6 to 8 weeks after commissioning carry out
the tests detailed in:
In-Service Tests
b) 12 to 15 weeks after commissioning carry
out the tests detailed in:
In-Service Tests
Depending on the results of the above tests,
several possibilities exist:
a) If no signicant changes (e.g. ≤ 1 K) in
mixed water temperatures are recorded
between commissioning and 6 to 8 week
testing, or between commissioning and
12-15 week testing the next in-service test
can be deferred to 24 to 28 weeks after
commissioning.
b) If small changes (e.g. 1 to 2 K) in mixed
water temperatures are recorded in only one
of these periods, necessitating adjustment of
the mixed water temperature, then the next
in-service test can be deferred to 24 to 28
weeks after commissioning.
c) If small changes (e.g. 1 to 2 K) in mixed
water temperatures are recorded in both of
these periods, necessitating adjustment of
the mixed water temperature, then the next
in-service test should be carried out at 18 to
21 weeks after commissioning.
d) If signicant changes (e.g. > 2 K) in mixed
water temperatures are recorded in either
of these periods, necessitating service work,
then the next in-service test should be carried
out at 18 to 21 weeks after commissioning.
The general principle to be observed after the
rst 2 or 3 in-service tests is that the intervals of
future tests should be set to those which previous
tests have shown can be achieved with no more
than a small change in mixed water temperature.
NOTE: A testing record page has been added to
the book for your use.

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 affect the product
surface nish and invalidate your guarantee.
Cleaning the Filters (g.A)
It is advised that this should be carried out by a
qualified person:
• Turn off the water supplies before starting.
• To gain access to the lters remove the unit
from the inlet ttings.
• Remove the lter housing and disassemble.
• Wash the filters thoroughly under running
water, use a suitable brush to remove all debris.
• Reassemble and fit in reverse order.
WARNING!
DO NOT use powerful abrasive or
solvent cleaning fluids when cleaning the
shower as they may damage the fittings.
MAINTENANCE
Maintenance of the unit is required to give
continued performance after installation and 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.
It is a requirement that all TYPE 3 approved
valves shall be veried against the original set
temperature results once every 12 months.
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 this work
out - 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.
NOTE: The NRV’s will only operate in one
direction - water should be able to ow into the
unit from the inlets, but NOT back out through
the inlets.
If these checks do not highlight the reason
for the temperature variation, then internal
components will require replacement - please see
the Spare Parts list.
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.
