Bar mixer shower
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
Running water pressure:
From 5 Meter head.
(0.5 bar min.)
5.0 bar max.
Maximum static water pressure:
Mains 10 bar
This mixer shower is designed for use with
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.
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 pipe work
can provide nominally equal pressures at the
mixer shower.
Replacement parts can be ordered from Triton Customer
Service. See ‘spare parts’ for details and part numbers.
Water minimum ow rate
For best performance within the specied
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
Recommended maximum: = 65°C
Minimum hot water temperature: = 52°C
Maximum cold water temperature: = 20°C
The mixer shower MUST NOT be subjected to
water temperatures above 80°C.
BS 6700 recommends that the temperature of
stored water should never exceed 65°C.
A stored water temperature of 60°C is considered
sufcient to meet all normal requirements and
will minimise the effects of scale in hard water
areas.
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 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 unit
as heat can transfer along the pipework and
damage the mixer valve.
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
signicantly affect the ow
• 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 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.
• It is preferable to ush the pipe-work 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)
• The manufacturer recommends for all
commercial applications that, 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.
b. For best performance the showerhead 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 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 applianceoperating manual to conrm compatibility with
this mixer shower).
Where thermal store systems and instantaneous
gas water heaters are used, if excessive drawoff 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 to the inlet
pipework 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
Pumped gravity fed systems (g.2)
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 (g.3)
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 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
manufacturer) and is in addition to the normally
larger central heating expansion vessel.

Unvented mains pressure systems (g.4)
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
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.5)
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
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 exposed
installation onto solid wall, a stud partition wall,
dry lined wall or xing to a laminate cubicle or
panel.
SITING OF THE SHOWER AND
ACCESSORIES
Refer to (g.6) for correct siting of the shower.
The mixer valve should be positioned, as
detailed, with all controls within comfortable
reached of the user.
The handset can be positioned above or to either
side of the shower.
