INTRODUCTION
This book contains all the necessary fitting and
operating instructions for your Triton Shower
Tower manual 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 your shower.
This shower tower is designed to operate on
the higher pressure systems found in the UK up
to a maximum of 6 bar running pressure.
The shower MUST NOT be subjected to water
temperatures above 80°C.
This mixer shower is suitable for fully
modulating type combination boilers and multi-
point hot water heaters. It is also suitable for
thermal storage, unvented systems and
pumped gravity systems.
Important: Before installing with a gas
instantaneous water heater, ensure it is
capable of delivering hot water at a
minimum switch-on flow rate 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 to a minimum
of 52°C. Water temperature at the inlet to
the mixer must remain relatively constant
when flowrate adjustments are made (refer to
the water heater operating manual to confirm
compatibility with this shower tower).
This shower tower is supplied with an integral
single check valve and integral large area filter
in each inlet elbow. Inlet connections are by
braid hoses having 1/2” BSP unions.
SAFETY WARNINGS
a 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.
b DO NOT choose a position where the
shower could become frozen.
c DO NOT connect this mixer shower to any
form of tap or fitting not recommended by
the manufacturer.
d The sprayhead must be regularly cleaned to
remove scale and debris.
e 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.
f 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.
g Do not operate the shower outside the
guidelines as laid out in ‘site requirements’.
Replacement parts can be ordered from Triton
Customer Service. See ‘spare parts’ for details
and part numbers.
Due to continuous improvement and updating,
specification may be altered without prior notice.
To ensure the product suitability for
commercial and multiple installations, please
contact Triton’s specification advisory service
prior to installation.

SITE REQUIREMENTS
The installation must be in accordance with
Water Regulations and Byelaws.
Minimum running water pressure: 0.5 bar
Maximum running water pressure: 6 bar
Maximum static water pressure: 7 bar
For otimum performance an operating
pressure of 3 bar running is required.
Both hot and cold supplies should be at
nominally equal pressures with a minimum flow
rate of 8 litres per minute to both inlets.
While the shower tower is operational (open
outlet), inlet pressures must not be capable of
exceeding 6 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 6 bar, the use of a suitably sized pressure
reducing valve fitted in the cold mains supply
pipework can provide nominally equal pressures
at the showertower.
For a satisfactory performance from the shower
tower both cold and hot inlet supplies must be
from a balanced supply.
Additional isolating valves must be fitted as an
independent means of isolating the water
supplies should maintenance be necessary.
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 systems and
instantaneous gas water 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
showertower temperature becoming noticeably
cooler.
DO NOT use jointing compounds on pipework.
Water temperature requirements
Recommended maximum 65°C.
BS6700 recommends 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 effects of
scale in hard water areas.
Temperature adjustment range
The mixed water temperature can be adjusted
from cold through to the temperature of hot
water available from the hot water appliance.
Flow rate performance
For all systems, the ability to use showerheads
and body jets simultaneously is dependent on
domestic hot water pressures and flow rates.

TYPICAL SUITABLE INSTALLATIONS
a) Instantaneous gas-heated systems,
e.g. combination boilers (fig.2)
The shower tower can be installed with a
multipoint 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
fitted if the supply pressures exceed 6 bar
running.
An expansion vessel (as shown in fig.2) MUST
be fitted, and regularly maintained, to ensure
the shower mixer 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.
b) Unvented mains pressure systems
(fig.3)
The shower tower 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 6 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.3)
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.
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.

c) High output thermal store systems
(fig.4)
Packages of this type, fitted with a blender valve
can be used. A drop tight pressure reducing
valve MUST be fitted if the supply pressures
exceed 6 bar running.
An expansion vessel (as shown in Fig.4) MUST
be fitted, 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).
d) Pump assisted gravity fed systems
(fig.5)
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.

Fig.7 (diagrammatic view – not to scale) SITING OF THE SHOWER
Refer to fig.7 for correct siting of the shower.
Position the shower on the wall so that all
controls can be comfortably reached whilst
using the shower.
IMPORTANT: The hot entry piping is on the
left-hand side of the mixer body.
INSTALLATION
General conditions
Note: The outlet of the shower must not be
connected to anything other than the hose and
sprayhead supplied.
DO NOT use jointing compounds on any pipe
fittings for the installation.
Use only the fittings supplied.
DO NOT solder fittings within the vicinity of the
shower tower as heat transfer can damage the
seals and valve components.
Note: Suitable isolating valves (complying with
Water Regulations and Byelaws) MUST be fitted
on the hot and cold water supplies to the
shower tower 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.
IMPORTANT: The water circuit should be
installed such that the flow is not
significantly affected by other taps and
appliances being operated elsewhere on the
premises. Water pressure must not fall below
specification of the shower.
Note: Hot water pipe entry must be made to
the left-hand side inlet.
WARNING!
THE SHOWER MUST NOT BE
POSITIONED WHERE IT WILL BE
SUBJECT TO FREEZING CONDITIONS.

Instantaneous Gas Water Heaters
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 to a minimum of 52°C and
delivering a flow rate of not less than eight litres
per minute.
Fitting the pipework
Establish the required position of the shower
tower and mark two holes for the incoming
water supplies.
The suggested final separation between pipe
centres is 150mm (fig.8).
Remove the plaster and brickwork (or
plasterboard) to the depth required and chase
out the additional areas to facilitate the
incoming pipework.
Complete the outlet pipework with a standard
15mm x 1/2” BSP female thread elbow or
straight coupler (depending on direction of
entry supplies).
It is prefereable to flush the pipework
(fig.9) to clear the system of debris and
check for leaks before connecting to the
elbows.
Complete any plastering and tiling.
Note: Pipes can be surface mounted but cut-
outs must be fashioned in the top or bottom of
the shower tower.
Fitting the hanging brackets
Using the centres of the supply holes as the
datum line (fig.10) mark the position for the
four locating screws for the hanging brackets,
ensuring they align vertically and horizontally.
The holes should be 6mm in diameter and
30mm deep; the distance between the two
hanging brackets should be 215.5mm.
Drill and plug the wall using the wallplugs
provided (the wallplugs are suitable for most brick
walls - use an appropriate masonry drill, but if the
wall is plasterboard or a soft building block, use
special wallplugs and a suitable drill bit).

Fitting the shower tower body
Wrap the supplied elbow threads with PTFE
tape and connect them to the hot and the cold
water pipes. Tighten to prevent leaking and
ensure the elbows face upwards (fig.12).
Fit the filter and check valve onto the elbow to
prevent debris entering the the mixer valve
(fig.13).
Facing the front of the shower tower body,
connect the left-hand flexible hose inside the
unit to the hot water elbow, and then connect
the right-hand flexible hose to the cold water
elbow (fig.14).
Screw tightly to avoid leaking. Note there is a
gasket on each hose which must be in place.
Hitch the two hooks inside the shower body
onto the hanging brackets on the wall. Ensure
the installation is stable.
Fitting the hose and sprayhead
Screw the fixed head (fig.15) to the topmost
outlet connector of the shower tower body,
making sure the sealing washer is in place.
Screw tight to ensure no leakage.
Connect the swivel nut of the shower hose to
the bottom outlet connector (fig.16) on the
shower tower body. Screw the other end of the
hose to the handset then locate the handset
into the handset bracket.
Check the pipework for stability and
tightness to avoid leaks before using the
shower tower.
Note: DO NOT use silicon sealant around the
shower tower since it may be necessary to
access and clean the inlet filters periodically.

USING THE MIXER CONTROL LEVER
Lift the lever up and water will flow from the
outlets, depending which has been selected via
the diverter valve. Press the lever down and the
water flow will cease (fig.17).
To obtain hot water turn the lever to the left. To
obtain cooler water turn the lever to the right
(fig.18).
Note: When showering is completed, close the
water supply off at the control lever. DO NOT
rely on the diverter valves to permanently shut
the water off.
USING THE DIVERTER VALVES
The diverter valves are combined on/off and
graduated flow controls.
Note: The diverter valves (fig.19) only operate
if the mixer control lever is on (lever up). The
temperature adjustment is controlled only from
the mixer control lever.
The upper diverter valve controls water
flow from the fixed head.
The middle diverter valve controls water
flow from the body jets.
The lower diverter valve controls water
flow from the handset.
Water volume increases by turning the diverter
valves counterclockwise. The water volume will
decrease by turning the diverter valves
clockwise.
CAUTION: It is recommended that persons
who may have difficulty understanding or
operating the controls should not be left
unattended while using the shower tower.
Special consideration should be given to young
children and the less able bodied.
