GENERAL

Isolate the electrical and water supplies before
removing the cover.

Read all of these instructions and retain them
for later use.

DO NOT take risks with plumbing or electrical
equipment.

Isolate electrical and water supplies before
proceeding with the installation.

The unit must be mounted onto the finished
wall surface (on top of the tiles). Do not tile up
to unit after fixing to wall.

Contact Customer Service (see back page), if
any of the following occur:

If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated.

If the unit shows a distinct change in
performance.

If the shower is frozen.
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,
contact Triton Customer Service.

The showerhead must be cleaned regularly
with descalent to remove scale and debris,
otherwise restrictions to the flow on the outlet
of the unit will result in higher temperatures
and could also cause the Pressure Relief Device
in the unit to operate.

This product is not suitable for mounting into
steam rooms or steam cubicles.

PLUMBING

The plumbing installation must comply with
Water Regulations, Building Regulations or any
particular regulations as specified by Local
Water Company or Water Undertakers and
should be in accordance with BS 6700.

The supply pipe must be flushed to clear
debris before connecting to the shower unit.

DO NOT solder pipes or fittings within

300mm of the shower unit, as heat can
transfer along the pipework and damage
components.

DO NOT fit any form of outlet flow control as
the outlet acts as a vent for the heater can.

DO NOT use excessive force when making
connections to the flexible hose or
showerhead, finger tight is sufficient.

All plumbing connections must be completed
before making the electrical connections.

ELECTRICAL

The installation must comply with BS 7671
‘Requirements for electrical installations’ (IEE
wiring regulations), building regulations or any
particular regulations as specified by the local
Electrical Supply Company.

This appliance MUST be earthed.
In accordance with ‘The Plugs and Sockets etc.

(Safety) Regulations 1994’, this appliance is
intended to be permanently connected to the
fixed wiring of the electrical mains system.

Make sure all electrical connections are tight
to prevent overheating.

Fuses do not give personal protection against
electric shock.

To enhance electrical safety a 30mA residual
current device (RCD) should be installed in all
UK electric and pumped shower circuits. This
may be part of the consumer unit or a
separate unit.

Switch off immediately at isolating switch if
water ceases to flow during use.

Other electrical equipment i.e. extractor fans,
pumps must not be connected to the circuits
within the unit.

Switch off at isolating switch when not in use.
This is a safety procedure recommended with
all electrical appliances.

As with all electrical appliances it is
recommended to have the shower and
installation checked at least every two years by
a competent electrician to ensure there is no
deterioration due to age and usage.

ADVICE TO USERS

The following points will help you understand
how the shower operates:

a.

The electric heating elements operate at a

constant rate at your chosen power setting. It
is the flow rate of the water passing through
the heater unit which determines the shower
temperature at any given setting (the slower
the flow the hotter the water becomes, and
the faster the flow the cooler the water).

b.

During winter, mains water supply will

be cooler than in summer. Therefore
the temperature of the shower will vary
between seasons on any one setting of the
temperature control, e.g. if you have chosen
setting number 6 as your preferred shower
temperature in the summer, you will have
to increase that number during winter by
adjusting the temperature control clockwise
(which in effect slows the water flow).

c.

The stabiliser valve minimises variations in

shower temperature during mains water
pressure changes. If changes in shower
temperature are experienced during normal
use, it will most likely be caused by the
water pressure falling near to or below the
minimum level. The drop in pressure may
be due to water being drawn off at other
points in the house while the shower is in
use. If pressure drops appreciably below
the minimum, the heating elements will
automatically cut out.

If ever the water becomes too hot and you
cannot obtain cooler water, first check that
the sprayplate in the showerhead has not
become blocked.

DO NOT place items such as soap or shampoo
bottles on top of the unit. Liquid could seep
through the joint between the cover and
backplate, and possibly damage the sealing
rubber.

Replacement parts can be ordered from Customer
Service. See ‘spare parts’ for details and part numbers.

The shower must only be connected to a
230-240V ac supply. If you are installing a
shower with a kilowatt rating above 9kW,
it is advisable to contact the local
electricity supply company.

The electrical rating of the shower is
shown on the rating label (Fig. ) within
the unit.

Before making any sort of electrical
connection within the installation make
sure that no terminal is live. If in any
doubt, switch off the whole installation at
the mains supply and remove the correct
fuse.

The shower must be connected to its own
independent electrical circuit. IT MUST
NOT be connected to a ring main, spur,
socket outlet, lighting circuit or cooker
circuit.

The electrical supply must be adequate for
the loading of the unit and existing
circuits.

Check your consumer unit (main fuse box)
has a main switch rating of 80A or above
and that it has a spare fuse way which will
take the fuse or Miniature Circuit Breaker
(MCB) necessary for the shower (Fig. ).

If your consumer unit has a rating below
80A or if there is no spare fuse way, then
the installation will not be straightforward
and may require a new consumer unit
serving the house or just the shower.

You will need to contact the local
electricity company. They will check the

serving the house or just the shower.

You will need to contact the local
electricity company. They will check the
supply and carry out what is necessary.
They will also check the main bonding.

The earth continuity conductor of the
electrical installation must be effectively
connected electrically to all exposed metal
parts of other appliances and services in
the room in which the shower is to be
installed, to conform to current IEE
regulations.

All exposed metallic parts in the bathroom
must be bonded together using a cable of
at least 4 mm² cross sectional area. These
parts include metal baths, radiators, water
pipes, taps and waste fittings.

For close circuit protection DO NOT use a
rewireable fuse. Instead use a suitably
rated Miniature Circuit Breaker (MCB) or
cartridge fuse (see Table A).

In the interest of electrical safety a 30mA
residual current device (RCD) should be
installed in all UK electric and pumped
shower circuits. This may be part of the
consumer unit or a separate unit.

A 45 amp double pole isolating switch
with a minimum contact gap of 3 mm in
both poles must be incorporated in the
circuit.

It must have a mechanical indicator
showing when the switch is in the OFF
position, and the wiring must be
connected to the switch without the use of
a plug or socket outlet.

The switch must be accessible and clearly
identifiable, but out of reach of a person
using a fixed bath or shower, except for
the cord of a cord operated switch, and

It must have a mechanical indicator
showing when the switch is in the OFF

connected to the switch without the use of
a plug or socket outlet.

The switch must be accessible and clearly
identifiable, but out of reach of a person
using a fixed bath or shower, except for
the cord of a cord operated switch, and
should be placed so that it is not possible
to touch the switch body while standing in
a bath or shower cubicle. It should be
readily accessible to switch off after using
the shower.

Where shower cubicles are located in any
rooms other than bathrooms, all socket
outlets in those rooms must be protected
by a 30mA RCD.

The current carrying capacity of the cable
must be at least that of the shower circuit
protection (see Table B).

To obtain full advantage of the power
provided by the shower, use the shortest
cable route possible from the consumer
unit to the shower.

It is also necessary to satisfy the
disconnection time and thermal
constraints which means that for any given
combination of current demand, voltage
drop and cable size, there is a maximum
permissible circuit length.

The shower circuit should be separated
from other circuits by at least twice the
diameter of the cable or conduit.

The current rating will be reduced if the
cabling is bunched with others,
surrounded by thermal loft or wall
insulation or placed in areas where the
ambient temperature is above 30°C. Under
these conditions, derating factors apply
and it is necessary to select a larger cable
size.

In the majority of installations, the cable
will unavoidably be placed in one or
more of the above conditions. This
being so, it is strongly recommended to
use a minimum of 10 mm cabling
throughout the shower installation.

In any event, it is essential that individual
site conditions are assessed by a
competent electrician in order to
determine the correct cable size and
permissible circuit length.

WATER REQUIREMENTS

The installation must be in accordance with
Water Regulations and Bylaws.

To ensure activating the heating elements, the
shower must be connected to a mains water
supply with a minimum running pressure of
100kPa (1.0 bar) at a minimum flow rate of
eight litres per minute.

The maximum static pressure must not exceed
1000kPa (10 bar).

Note: If the stated flow rate is not available,
it may not be possible to achieve the best
performance from the unit throughout the year.

For guidance on the running and static pressures
contact the local Water Authority or consult a
competent plumber.

During periods of high ambient temperatures it
may be necessary to select a low power setting
to achieve your preferred shower temperature.

The water supply can be taken from a cold water
storage cistern provided there is a minimum
head of ten metres above the showerhead. It
must be an independent supply to the shower
only.

If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated, contact Customer Service for
advice.

Fig.5 shows a typical system layout.

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

7

Forte

SITING OF THE SHOWER

IMPORTANT: For ease of servicing, the unit
must always be mounted on the surface of
tiled walls. NEVER tile up to the unit.

Refer to

fig.5 for correct siting of shower.

Position the unit where it will

NOT be in direct
contact with water from the showerhead.
Position the shower unit vertically.

Allow enough room between the ceiling and the
shower to access the cover top screws.

Note: Water Regulations require the showerhead
be ‘constrained by a fixed or sliding attachment

so that it can only discharge water at a point
not less than 25 mm above the spill-over level
of the relevant bath, shower tray or other fixed
appliance’. The use of the supplied retaining ring

will in most cases meet this requirement, but if
the showerhead can be placed within a bath,
basin or shower tray, then a double check valve,
or similar, must be fitted in the supply pipework
to prevent back-flow.

Pressure relief safety device

A pressure relief device (PRD) is designed into
the shower unit which complies with European
standards. The PRD provides a level of appliance
protection should an excessive build up of
pressure occur within the shower.

DO NOT operate the shower with a damaged or
kinked shower hose, or a blocked showerhead
which can cause the PRD to operate.

When commissioning, the showerhead must
be removed from the flexible hose, while at the
same time the temperature control must be at
the minimum flow position. Failure to follow this
procedure may also cause the PRD to operate.

Make sure the shower is positioned over a bath
or shower tray because if the PRD operates, then
water will eject from the bottom of the unit.

Should this happen, turn off the electricity and
water supplies to the shower at the isolating
switch and stopvalve. Contact Customer Service
for advice on replacing the PRD.

FITTING THE SHOWER TO THE WALL

Note: The control knobs are an integral part of
the cover – DO NOT attempt to remove them.

Lift the cover from the backplate. Remove the
trimplate by removing the two fixings screws.
This will make the pipe and cable connections
easier

(fig.6).

Entry positions for the mains water and electric
cable are from the top, bottom, either side or
from the back.

Note: Deviations from the designated entry
points will invalidate product approvals.

If a bottom entry has been chosen, fit the
supplied pipe trim in the top of the backplate
(fig.7).

If a top entry has been chosen, fit the supplied
pipe trim in the bottom of the trimplate

(fig.8).

If a side entry is required, the trimplate side will
have to be cut. With the elbow compression
fitted on the outlet, temporarily place the
trimplate into position, then mark the pipe entry
on the side of the trimplate. Carefully remove
the appropriate area using a junior hacksaw.

If installing a feed pipe from the back or bottom,
the centre of the inlet valve to the wall surface is
20 mm (fig.9).

Note: If entry is from the back, the nut of the
compression fitting will be partially behind the
surface of the wall. This area

MUST be left clear
when plastering over the pipework in order to
make the nut accessible for future adjustments.

After choosing the site for the shower, use the
backplate as a template and mark the two fixing
holes

(fig.10).

Drill and plug to suit the fixing screws supplied.

(The wall plugs provided are suitable for most brick
walls – use an appropriate masonry drill, but if the

Screw the top fixing screw into position leaving
the base of the screw head protruding 6 mm out
from the wall.

Hook the backplate over the top screw and fit
the bottom fixing screw into position.

DO NOT fully tighten the screws at this stage,
as the fixing holes are elongated to allow for
out of square adjustment after the plumbing
connections have been completed.

PLUMBING CONNECTIONS

Plumbing to be carried out before wiring

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

DO NOT solder fittings near the shower unit
as heat can transfer along the pipework and
damage components.

Standard 15 mm x 15 mm brass compression
fittings MUST be used to connect to the inlet of
the shower.

Note: An additional stopvalve (complying with
Water Regulations and Bylaws)

MUST be fitted
in the mains water supply to the shower as an
independent means of isolating the water in
order to carry out maintenance or servicing.

IMPORTANT: Before completing the
connection of the water supply to the inlet
of the shower, and in compliance with
Water Regulations, flush out the pipework
to remove all swarf and system debris. This
can be achieved by connecting a hose to the
pipework and turning on the mains water
supply long enough to clear the debris to
waste.

Procedure

Turn off the water supply either at the mains
stopvalve or the isolating stopvalve. Connect the
mains water supply to the inlet of the shower
via 15 mm copper, stainless steel or plastic pipe
using a 15 mm x 15 mm brass compression
fitting.

Note: The inlet fitting is designed to enter a
compression fitting only.

DO NOT use push­fit connectors as full engagement cannot be
guaranteed. DO NOT use excessive force when
making these connections.

Make sure the backplate is square on the wall
and tighten the two retaining screws which hold
it to the wall.

Turn on the mains water supply and check for
leaks in the pipework connection to the shower.

IMPORTANT: Using a suitable sealant, always
seal around the incoming pipework to
prevent water entering the wall.

Note: At this stage no water can flow through
the unit.

WARNING!

The outlet of the shower acts as a

vent and must not be connected to

anything other than the hose and

showerhead supplied.

Fig.11 shows a schematic wiring diagram.

The cable entry points are shown in

fig.1.

The cable can be surface clipped, hidden or via
20 mm conduit.

Note: Conduit entry can only be from rear.
Route the cable into the shower unit and
connect to the terminal block (fig.12) as
follows:

Earth cable to terminal marked E

Neutral cable to terminal marked N

Live cable to terminal marked L

IMPORTANT: Fully tighten the terminal
block screws and make sure that no cable
insulation is trapped under the screws. Loose
connections can result in cable overheating.

Note: The supply cable earth conductor must
be sleeved. The outer sheath of the supply cable
must be stripped back to the minimum.

The supply cable must be secured either by
routing through conduit or in trunking or by
embedding in the wall, in accordance with
current IEE regulations.

The use of connections within the unit, or other
points in the shower circuit, to supply power to
other equipment e.g. extractor fans, pumps etc.
will invalidate the guarantee.

DO NOT switch on the electricity supply until
the cover has been fitted.

Note:

The elements on UK models are to 240V
specification and will give a lower kW rating if the
voltage supply is below 240V.

REPLACING THE COVER

Locate the trimplate into the backplate and
secure with the two fixing screws.

The power selector spindle must be aligned as
shown

(fig.13).

To check that the temperature control is
correctly positioned on the stabilising valve,
temporarily place the cover in position so that
the splines engage and rotate the temperature
control fully anti-clockwise.

Remove the cover and position the temperature
control knob so that it points to the maximum
flow position

(fig.14). Position the power

selector to the STOP position (fig.15).

Replace the cover squarely to the backplate and
guide into position so that the knobs locate
correctly into the splined spindles.

Should any difficulty arise, recheck the points
above.

Secure the cover in position with the four

COMMISSIONING

The first operation of the shower is intended to
flush out any remaining unit debris, and to make
sure the heater unit contains water before the
elements are switched on. This operation must
be carried out with the flexible hose screwed to
the outlet but without the showerhead attached.
Make sure the outlet of the flexible hose is
directed to waste.

Before turning on the electric and mains water
supplies to the shower, check the power selector
is at the

STOP position (fig.15) and the

temperature control is rotated fully clockwise to
the minimum flow position (fig.16).

Note: Failure to turn the temperature control to
the minimum flow position may cause the PRD
to operate.

Turn on the mains water supply to the shower
at the isolating stopvalve and then the electric
supply at the isolating switch. The power
indicator will light.

Switch the power selector to the COLD position
(fig.17) and wait until water starts to flow from
the flexible hose.

Slowly rotate the temperature control fully
anti-clockwise to the maximum flow position
(fig.18).

It will take about thirty seconds for a smooth
flow of water to be obtained while air and any
debris is being dispersed from the shower.

When a smooth flow of water is obtained, rotate
the temperature control from minimum to
maximum several times to release any trapped
air within the unit.

Once flushing out has been completed, stop the

To start the shower

Turn the power selector to the red or blue
symbol positions and water will start to flow.

To stop the shower

Switch the power selector to the STOP position
and water will cease to flow.

To use the power selector

The power selector has four positions – STOP,
COLD, ECONOMY and HIGH – as shown in
fig.19.

The grey symbol

is the STOP position and is
to switch off the electric and water supply at the
shower; no flow or power used.

The blue symbol

is the COLD setting
for cooler water only. Adjustment of the
temperature control at this setting will only alter
the force of the water from the showerhead. IT
WILL NOT ALTER THE WATER TEMPERATURE.

The red symbol is the ECONOMY setting
for using less power during warmer months.
Temperature adjustment at this setting is via the
temperature control.

Note: If the stated flow rate required for the unit
cannot be met due to low water pressure, it will
be necessary to operate the unit on

ECONOMY
setting during the warmer months because of
flow rate limitations entering the unit.

preferred temperature. This setting should
normally be regarded as optimum shower
performance throughout the year. Temperature
adjustment at this setting is via the temperature
control.

To adjust the shower temperature

Alter the water temperature by increasing or
decreasing the flow rate of the water through the
shower via the temperature control (fig.20).

After finding your preferred shower temperature,
the temperature control setting can be
remembered and left as the normal setting. This
should only need to be altered to compensate
for seasonal changes in ambient water
temperature.

Note: The preferred setting on

ECONOMY will
give a different temperature to the same setting
on HIGH.

To decrease the shower temperature

Turn the temperature control anti-clockwise
(fig.20); this will increase the flow of water
through the shower.

To increase the shower temperature

Turn the temperature control clockwise (fig.21);
this will decrease the flow of water through the
shower.

Note: It is advisable to be certain that the
showering temperature is satisfactory by testing
with your hand before stepping under the
showerhead. There will always be a time delay of
a few seconds between selecting a flow rate and
the water reaching the stable temperature for
that flow rate.

CAUTION: This appliance is not intended
for use by persons (including children)
with reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, unless they have been given
supervision or instruction concerning use of
the appliance by a person responsible for
their safety.

Children should be supervised to ensure that

OPERATING FUNCTIONS

Power on indicator (fig.22)

When the electricity supply to the shower is
switched on at the isolating switch, the ‘Power
On’ indicator will light.

Note: Should the safety cut-out device operate,
the indicator will remain lit.

Low water pressure cut-out

If the water pressure falls below the minimum
required for correct operation of the shower,
power will be switched off to the heating
elements preventing any maintained
temperature rises (water will continue to flow).

Power will automatically be restored when
adequate water pressure returns.

Temperature limiter

During normal operation if an overheat
temperature is sensed, power to the elements
will be reduced. Water will continue to flow.
When the temperature has cooled sufficiently,
power to the elements will be automatically
restored to the previous setting at the time of
interruption.

Safety cut-out

The unit is fitted with a non-resettable
thermal cut-out safety device. In the event of
abnormal operation which could cause unsafe
temperatures within the unit, the device will
disconnect the heating elements. It will require a
visit from a qualified engineer to determine the
nature of the fault and replace the safety device,
once the unit has been repaired.

NOTE: In normal use, it is in order to leave the
water supply permanently on to the shower
unit, but as with most electrical appliances,

the unit must be switched off at the
isolating switch when not in use.

CLEANING

Before cleaning, turn off the unit at the isolation
switch to avoid the shower being accidentally
switched on.

Triton recommends that all products are
cleaned using warm, soapy water.

IT IS IMPORTANT TO KEEP THE SHOWERHEAD
CLEAN TO MAINTAIN THE PERFORMANCE
OF THE SHOWER. The hardness of the water
will determine the frequency of cleaning. For
example, if the shower is used every day in a
very hard water area, it may be necessary to
clean the showerhead on a weekly basis.

WARNING!

DO NOT use abrasive or aggressive

cleaning products when cleaning the

shower as they may damage the unit.

18

Forte

CLEANING THE INLET FILTER

It is recommended that the filter is periodically
cleaned in order to maintain the performance of
the shower. It is essential that this operation is
carried out by a competent person.

SWITCH OFF THE ELECTRICITY SUPPLY AT
THE MAINS.

Remove the cover. The inlet filter is situated in
the inlet pipe which is part of the solenoid valve
(fig.23).

To gain access to the filter, remove the
trimplate and disconnect and remove the
compression fitting. Also, depending on the
incoming pipework arrangements and if there
is not enough slack in the pipework, it may be
necessary to remove the unit from the wall.

When cleaning the filter,

DO NOT use a sharp
object, as it will cause damage. It is preferable to
use an old toothbrush or similar.

When the filter is clean, recommission the unit.
