INTRODUCTION

his book contains all the necessary ﬁtting and operating instructions for your Triton high pressure thermostatic mixer shower. Please read them carefully.

Please read through the whole of this book before beginning your installation.

he 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.

hermostatic mixers will automatically maintain y

our chosen temperature, even if taps are turned on elsewhere in the house, and shut off if either the hot or cold supply fails.

For the best performance within the speciﬁed running pressure range a minimum ﬂow of eight litres per minute should be available to both inlets.

he mixer shower MUST NOT be subjected to w

ater temperatures above 80°C.

his mixer is designed to operate on higher pressure systems found in the UK up to a maximum of 5 bar running pressure.

he high pressure valve is suitable for modulating type combination boilers and multi-point hot w

ater heaters. It is also suitable for thermal storage, unvented systems and pumped gravity systems.

IMPORTANT: Before installing with a gas instantaneous water heater, make sure it is capable of delivering hot water at a minimum switch-on ﬂow rate of 3 litres per minute. At ﬂ

ow rates between 3 and 8 litres per minute, the appliance must be capable of raising the w

ater temperature to a minimum of 52°C.

he water temperature at the inlet to the mixer must remain relatively constant when ﬂow rate adjustments are made.

Inlet connections are by compression ﬁttings for 15mm copper pipe.

his valve unit is supplied with a mounting bracket to suit installation in a chased out cavity in a solid wall, a stud partition wall, dry lined wall or ﬁxing to a shower cubicle or panel.

SAFETY WARNINGS

Layout and sizing of pipework MUST be such that when other services are used, pressures at the shower control inlets do not fall below the recommended minimum.

DO NOT choose a position where the shower could become frozen.

The outlet of this appliance MUST NOT be connected to any form of tap or ﬁtting not recommended by the manufacturer.

The showerhead MUST be regularly cleaned to remove scale and debris.

Conveniently situated isolating valves in each inlet supply MUST be ﬁtted as an independent method of isolating the shower should maintenance or servicing be necessary.

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 ﬁtted. For advice on the Triton scale inhibitor, please contact Customer Service.

Do not operate the shower outside the guidelines as laid out in ‘site requirements’.

SITE REQUIREMENTS

The installation must be in accordance with W

ater Regulations/Bylaws.

Minimum running water pressure: 1 bar.

Maximum running water pressure: 5 bar.

Maximum static water pressure: 10 bar.

For the best performance within the speciﬁed pressure range both hot and cold water supplies must be fed from a common supply and a minimum ﬂow of 8 litres per minute should be available to both inlets.

hile the mixer valve is operational (open outlet), inlet pressures MUST NOT be capable of exceeding 7 bar. For effective operation of the internal seals, the maximum static pressure must not be exceeded.

Note: On sites where the running pressure is above 5 bar, the use of a suitably sized pressure reducing valve ﬁtted in the cold mains supply pipework can provide nominally equal pressures at the mixer valve. This should be installed as indicated on the appropriate diagrams shown on the following pages, and set to within the speciﬁcation of the valve.

For the best performance of this shower both hot and cold water supplies to the shower valve should be fed at nominally equal pressures.

The pipework should be installed such that the ﬂ

ow is not signiﬁcantly affected by other taps and appliances being operated elsewhere on the premises.

Note: Where thermal store/combi boilers or multi-point heaters are used, if excessive draw offs take place the boiler may not be able to maintain an adequate output temperature. This could result in the shower temperature becoming noticeably cooler.

For effective thermostatic control the temperature of the hot water entering the mixer should remain a minimum of 10°C above the selected output temperature.

The supply pipework must be ﬂushed to clear debris before connecting to the shower control accordance with Water Regulations and Bylaws.

DO NOT use jointing compounds on the pipework.

TYPICAL SUITABLE INSTALLATIONS

a) Instantaneous gas-heated showers, e.g. combination boilers (fig.2)

The shower control MUST be installed with a multipoint gas water heater or combination boiler of a fully modulating design (i.e. where the water draw-off rate indirectly controls the gas flow to the burner). A drop tight pressure reducing valve MUST be fitted if the supply pressures exceed 5 bar maintained.

An expansion vessel (shown in fig.2) MUST be fitted, and regularly maintained, to make sure the unit is not 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.

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 hot supply temperature MUST remain a minimum of 10°C hotter than the required blend temperature for the best performance.

b) Pump assisted gravity fed systems

(fig.3)

The pump MUST be fed from a cold water cistern and hot water cylinder providing nominally equal pressures. The pump must be capable of maintaining a minimum running pressure of 1 bar.

c) Unvented mains pressure showers

(fig.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 fit 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 (fig.4) may be required if a second pressure reducing valve is installed. This does not apply to

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.

d) Mains pressurised thermal store

(fig.5)

Packages of this type, fitted with a tempering valve (blender valve) can be used. A drop tight pressure reducing valve MUST be fitted if the supply pressures exceed 5 bar maintained.

An expansion vessel (shown in fig.5) MUST be fitted, and regularly maintained, to make sure 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).

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.

PREPARING THE MIXER VALVE Before starting the installation, make sure all the

openings on the valve are carefully covered to prevent ingress of any debris etc.

Note: It is not necessary to remove the control knobs at any stage.

SITING OF THE SHOWER

Refer to fig.6 for correct siting of the shower.

Position the shower and showerhead on the wall so that all controls can be comfortably reached while using the shower. The showerhead and riser rail can be positioned either side of the shower.

Note: Pipe entry for both surface-mounted and flush-fitted valves can be from the top, bottom or rear.

The hot entry port is on the left-hand side of the valve and is marked on the valve with a letter ‘H’

(fig.7).

Note: The outlet of the shower must not be connected to anything other than the hose and showerhead supplied. DO NOT use jointing compounds on any pipe fittings for the installation.

DO NOT as heat transfer can damage components.

Note: Suitable isolating valves (complying with Water Regulations) must be fitted on the hot and cold water supplies to the shower as an independent means of isolating water supplies should maintenance or servicing be necessary.

When connecting pipework avoid using tight 90° elbows. Swept or formed bends will give the best performance.

Having decided on the position of the shower and direction of pipe entry, complete the pipework to the shower area.

Note: The final separation between pipe centres needs to be about 153 mm but absolute accuracy is not needed as the inlet elbows are adjustable between 146 mm and 160 mm.

Flush pipework to clear the system of all debris and check for leaks.

IMPORTANT:

screws are slack allowing the inlet elbows to rotate to the correct position and move freely in

and out of the valve housing (fig.8).

Place the valve housing centrally between the two pipes, and mark the two diagonal fixing

holes (figs.9 and 10).

Remove the valve. Drill and plug the holes.

(The wall plugs supplied are suitable for most brick walls — use an appropriate masonry drill, but if wall is plasterboard or a soft building block, you must use suitable wal lplugs and an appropriate drill bit).

Fit the nut covers on to the pipes (fig.11).

Note: Slide the pipes into the small diameter

end of the nut cover. It will not fit if inserted from the other end.

Slide the inlet nuts and olives onto the pipes, followed by the inlet trims.

Note: The holes in the inlet trims are offset to allow for adjustable inlet pipe separation widths. If pipe centre separation is 153 mm or less, then have the short side of the inlet trims between the pipes. If the pipe separation gap is 153 mm or greater, have the long side of the inlet trims

between the pipes (fig.12). If in any doubt try the cover to see if it fits properly (i.e. no visible gaps between the inlet trims and the cover —

fig.13). If there is a gap (fig.14) then reverse the trim.

While trying the cover make sure the inlet nuts are sitting in the holes in the inlet trim holes so that the inlet trims are at the correct separation.

Having positioned the inlet trims correctly, refit the valve to the pipework. Make sure the hot inlet port (marked with the letter ‘H’ on the valve housing) is connected to the hot pipework which must be on the left.

Screw to the wall with the two screws supplied (fig.15). Tighten the inlet nuts and inlet elbow

grub screws.

If installing a tamperproof fixed head, fit the outlet adaptor into the top outlet hole in the

valve housing (fig.16). The adaptor is sealed with an ‘O’ ring. Make sure the adaptor is fitted with the hose end in the valve housing. Fit the blanking plug into the bottom outlet hole using an ‘O’ ring to seal it.

If installing a riser rail, fit the outlet adaptor into the bottom outlet hole in the valve housing. The adaptor is sealed with an ‘O’ ring.

Make sure the adapter is fitted with the pipe end in the valve housing (fig.17)

Fit the blanking plug into the top outlet hole using an ‘O’ ring to seal it (fig.18). Make sure

both the adaptor and blanking plug do not protrude, and finish flush with the inner face of the housing.

If fitting a tamperproof fixed head, refer to ‘Fitting the tamperproof fixed head’ section and complete the outlet pipework as follows:

Determine the required height of pipe and cut to size. Slide nut cover onto the pipe, followed by nut and olive. Insert the pipe into outlet adaptor, place the outlet trim onto the adaptor and fully tighten the compression nut (fig.19).

Before securing the tamperproof fixed head to the wall, connect a hose to the pipework and direct to waste.

If fitting a riser rail, connect the shower hose to the outlet and direct to waste.

Open the isolating valves to the shower and flush through making sure the flow control is opened fully and the temperature control is rotated to ‘HOT’ and then to ‘COLD’ (if necessary depress the maximum temperature override button). Check for any leaks and remedy if necessary.

Slide the outlet blanking trim onto the cover where it is required i.e. bottom outlet for fixed

head, top outlet for a hose (fig.20).

Fit the cover on and secure with two screws (fig.21). Locate the lugs on the trim ring in the

holes on the cover and twist clockwise (fig.22). Finally, pull nut covers over nuts.

Complete the fitting of the shower accessories by referring to the appropriate section.
