INTRODUCTION

This book contains all the necessary fitting and
operating instructions for your Triton dual control
mixer shower. Please read them carefully. 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 ensure a
long and trouble free life from the shower.

This thermostatic shower valve has been
independently tested and approved to all the
requirements of

Specification D08 Thermostatic Mixing Valves
(Healthcare Premises) to the following

designations and for the following applications:

HP-S Shower with supply pressures of

LP -S Shower with supply pressures of

For optimum performance within the specified
running pressure range a minimum flow of 8 litres
per minute should be available to both inlets.

The valve is suitable for fully modulating
type combination boilers and multi-point hot
water heaters. Also suitable for thermal
storage, unvented systems and pumped
gravity systems.

Important: Before installing with a gas
instantaneous water heater, ensure the
appliance is capable of hot water delivery at
a minimum switch on flowrate of 3 litres per
minute. At flow rates between 3 and 8 litres
per minute the appliance must be capable of
raising the water temperature by 45°C.
Water temperature at the inlet to the mixer
must remain relatively constant when
flowrate adjustments are made.

The valve unit can be fitted in any orientation. For
a wall mounted sprayhead installation, the
plumbing will be simplified if the outlet is fitted
upwards.

The valve is supplied with an integral single check
valve and integral large area filter on each inlet.

Inlet connections are by compression fittings for

NHS Estates Model Engineering

1 - 5 Bar and unrestricted flow rate.

0.2 - 1 Bar and unrestricted flow rate.

15mm copper pipe.

This 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. It is also supplied
with an attached tiling shroud which provides
protection for the unit.

SAFETY WARNINGS

1

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.

2 DO NOT choose a position where the shower

could become frozen.

3 The outlet of this appliance must not be

connected to any form of tap or fitting not
recommended by the manufacturer.

4 The sprayhead must be cleaned regularly to

remove scale and debris.

5 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.

6 If it is intended to operate the shower in areas

of hard water it is advisable to fit a scale
inhibitor.

7 If it is intended to operate the shower outside

the guidelines laid out in the requirements
then see NOTE below.

NOTE: In the event of items 2 and 7, contact
Triton Customer Service for advice.
Tel: [phone].

Replacement parts can be ordered from Triton
Customer Service. See
part numbers.

Due to continuous improvement and updating,
specification may be altered without prior notice.

SITE REQUIREMENTS

The installation must be in accordance with Water
Regulation Byelaws and BS6700.

Minimum running water pressure: 0.2 bar.

Maximum running water pressure: 5 bar.

Maximum static water pressure: 10 bar.

For optimum performance within the specified
running pressure range a minimum flow of 8 litres
per minute should be available to both inlets.

Whilst 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.

For optimum 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
flow 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.

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

BS6700 recommends that the temperature of
stored water should never exceed 65°C.
A stored water temperature of 60°C is considered
sufficient to meet all normal requirements and will
minimise the affects of scale in hard water areas.

pre-set during installation – factory set at
approximately 39°C), with full anti-scald
protection throughout the range.

Fig.2 shows a typical gravity fed installation. (The
distance between the bottom of the cold water
cistern and the sprayhead must be at least 2
metres).
Fig.3 depicts a typical combination boiler
installation.

hot water storage system.

DO NOT use jointing compounds on
pipework.

INSTANTANEOUS WATER HEATERS

APPLIANCE CAPABILITIES

In order to ensure the optimum performance from
the shower when connected to an instantaneous
water heater, the appliance must be capable of
raising the temperature of the incoming water by
45°C (81°F) and delivering a flow rate of not less
than 8 litres per minute.

A flow limiter is supplied for the insertion into the
shower head which controls the maximum flow of
8 litres per minute.

To fit the flow limiter unscrew the shower head
from the ball joint. Insert the flow limiter flat face
up into the shower head (fig.5) fit the flat face
washer and refit the shower head to the ball joint.

With the flow limiter fitted and when the system
is in use, the on/off flow control should be turned
fully anti-clockwise to full flow setting.

PREPARING THE MIXER VALVE

Check the contents to ensure all parts are present.

Ensure the supplied metal fixing bracket, tiling
shroud, cranked spanner, lock nut key and allen
key are all to hand.

Before commencing the installation, make sure all
the apertures on the valve are carefully covered to
prevent ingress of any debris etc.

The 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. It is also supplied
with an attached tiling shroud which provides
protection for the valve both for transit and on
site. It should be left on at all times until such time
when it is being installed.

The hot and cold water pipes should not be
permanently attached to the wall closer than 2m
from the valve prior to installation to allow for
final adjustment of the valve position.

SITING OF THE SHOWER

WARNING:

THE SHOWER MUST NOT BE
POSITIONED WHERE IT WILL BE SUBJECT TO
FREEZING CONDITIONS.

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

Position the shower and sprayhead on the wall so
that all controls can be comfortably reached whilst
using the shower. The spray head can be
positioned either side of the shower.

The valve unit can be fitted in any orientation. For
a wall mounted sprayhead installation, the
plumbing will be simplified if the outlet is fitted
upwards.

a) General conditions

NOTE: The outlet of the shower must not be
connected to any tap or fitting not
recommended by Triton Plc.

DO NOT use jointing compounds on any pipe
fittings for the installation.

Use only the compression fittings supplied. DO
NOT solder fittings within the vicinity of the
valve unit as heat transfer can damage the seals
and thermostatic components.

NOTE: Suitable isolating valves (complying with
Water Regulation Byelaws) MUST be fitted 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.

When connecting pipework avoid using tight
90° elbows. Swept or formed bends will ensure
optimum performance.

The valve unit can be fitted in any orientation
(fig.7), but for a wall mounted sprayhead
installation, the plumbing will be simplified if
the outlet is fitted upwards. Access to the
integral strainers will also be improved with this
configuration.

The hot water inlet is identified with a red mark,
the cold water inlet with a blue mark. The
swivel inlets allow for either rising or falling hot
and cold water supplies. Note the swivel inlets
have ‘O’ seals to the body and do not require
PTFE tape or other means of sealing.

Gently screw the swivel inlets into the body of
the valve unit and stop as soon as resistance is
felt. Then back off by up to 1.5 turns to align
the inlet with the hot and cold supply pipes.
THE SWIVEL INLETS MUST NOT BE TIGHTENED
AGAINST THE VALVE BODY TO MAKE A SEAL
(fig.8).

The Triton dual control mixer valve includes a
mounting bracket which allows the installer to
mount the shower into a solid, stud partition or
other hollow wall structures. The bracket can
also be used for fitting in a shower cubicle or
panel providing the back of the cubicle or panel
is accessible.
