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 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
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 sufcient 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 signicantly 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 conrm 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.
