Standards and Approvals
Splashproof rating IPX4.
Complies with the requirements of current British
and European safety standards for household
and similar electrical appliances.
IMPORTANT: When first installed the unit
will be empty. It is essential the unit should
contain water before the elements are
switched on. It is vital that the
I-001-A
commissioning procedure is followed.
Failure to carry out this operation will result
in damage to the unit and will invalidate the
guarantee.
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 the winter the cold water supply
will be cooler than in the summer months.
Therefore, the temperature of the water
will vary from season to season on any one
setting of the temperature control, e.g. if
you have chosen 'medium' power for your
preferred shower temperature in the summer,
you may have to increase that to 'full' power
during the winter months.
c. If for any reason there is a sudden rise in
water temperature, the shower has thermal
cut-out devices built-in (see items 3 and 4
under ‘Fault Finding’).
d. If water ceases to flow switch off the shower at
the start/stop button and the isolating switch.
Contact Triton Customer Service for advice.
If ever the water becomes too hot and you
cannot obtain cooler water, first check that the
sprayplate in the showerhead is not 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.
Complies with requirements of the British
Electrotechnical Approvals Board (BEAB).
Meets with Compliance with European
Community Directives (CE).
Replacement parts can be ordered from Customer
Service. See ‘spare parts’ for details and part numbers.

‘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 soap dish will
in most cases meet this requirement, but if the
showerhead can be placed within a bath, basin

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
P-001-A
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.

WARNING!
Check there are no hidden cables or
pipes before drilling holes for wall
W-005-A
plugs. Use great care when using power
tools near water. The use of a residual
current device (RCD) is recommended.
Note: The control knobs are an integral part of
the cover – do not attempt to remove them.
Important: The unit must be mounted on
a flat surface which covers the full width and
length of the backplate. It is important that
the wall surface is flat otherwise difficulty
may be encountered when fitting the cover
and subsequent operation of the unit may be
impaired.
Unscrew the two top and one bottom retaining
screws (fig.7) and lift the cover from the
backplate.
Note: Deviations from the designated entry
points will invalidate product approvals.
Fig.8
If a top entry is required for the water pipe,
remove the top cut-out in the backplate (fig.8)
and rotate the inlet elbow so that it points
upward. If a bottom entry is required for the cold
water pipe, then a hole will need to be cut out of
the cover (fig.9) and the inlet elbow rotated to
face downward.
If entry is required from the back, rotate the inlet
elbow upwards and fit the supplied elbow to
connect to the pipe (fig.10).
Make sure the hole in which the pipe enters
through the wall is filled in completely in order to
stop any possible ingress of water into the cavity
area.
Fig.9
After choosing the site for the shower, use the
backplate as a template and mark the three fixing
holes (fig.11).
Drill and plug the wall to suit the fixing screws
supplied. (The wall plugs provided are suitable
for most brick walls – use an appropriate masonry
drill, but if the wall is plasterboard or a soft building
block, you must use suitable wall plugs and an
appropriate drill bit).
Screw the two upper fixing screws into position

Hook the backplate over the top screws and fit
the lower 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.
Note: A temporary factory fitted locking screw is
fitted to the power selector spindle (fig.12). This
is to make sure the spindle is held in the Cold
position while the commissioning procedure is
carried out. DO NOT remove the locking screw

WARNING!
The outlet of the shower acts as a
vent and MUST
NOT be connected to
W-004-A
anything other than the hose and
showerhead supplied.
Important: Before completing the
connection of the water supply to the inlet
of the shower, 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 water
supply long enough to clear the debris to
waste.
PLUMBING
CONNECTIONS
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.
Note: An additional gate valve or fullway lever
valve must be fitted in the water supply to the
shower as an independent means of isolating the
water supply should maintenance or servicing be
necessary.
Important: The fitting on the inlet elbow is
a push-in type. The pipework must be cut with
a pipe cutter and all burrs and rough edges
removed from the end of the tube. The fitting
can be used with copper and plastic pipe.
If using chrome plated copper pipe, remove
the first 25 mm of plating completely from
the connecting surface. If it is not completely
removed then the collet will not grip the pipe
and under pressure the pipe may be forced out.
Procedure
Turn off water supply either at the mains
stopvalve or the isolating stopvalve to the cistern.
Drain the cistern.
Important: The pipework must be brought
direct from the cold water storage cistern with
no other cold water draw offs between the
shower and the cistern.
Fit the pipework to the inlet elbow. Make sure
the elbow collet is fully engaged with the pipe.
Although the pipework connection to the shower
is via 15 mm diameter pipework, on long runs use

COMMISSIONING
Commissioning
Fig.15
WARNING!
Before normal operation of the
shower, it isW-001-A
essential the following
commissioning procedure is completed
correctly.
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.
Fig.16
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. The
cold position must be used.
To check that the temperature control is
correctly positioned on the stabilising valve,
temporarily place the cover in position so that
the splines engage then rotate the temperature
control fully anti-clockwise.
Fig.17
IMPORTANT
DO NOT TURN SELECTOR
SPINDLE UNTIL
COMMISSIONING
PROCEDURE HAS
BEEN CARRIED OUT
Remove the cover and position the temperature
control so that it points towards ‘1’ (fig.15).
REFER TO FITTING INSTRUCTIONS
Position the power selector to the cold position
(fig.16).
Locking
screw
Do not remove the locking screw fitted to
the power selector spindle (fig.17) – it can
be removed only when the commissioning
procedure has been completed.
Make sure the water supply is still turned on to
the shower.
Fig.18
Bleed screw
Drain tube
Open the bleed screw on the pump unit
(fig.18) by rotating one revolution. When water
flows from the drain pipe, this indicates that any
trapped air is vented and that the pump unit is
primed. The bleed valve must now be closed by
rotating in the opposite direction.
Offer the cover to the backplate unit. Check that
the power selector is still at the Cold position
and the temperature control is at ‘1’.
Note: Check the Start/Stop button is
not depressed in the cover which indicates
‘start’. The button should be flush with the
cover, otherwise water will flow as soon as the
electricity is switched on.

Attached to the Start/Stop button inside the
cover is a two-wire lead. The socket on the end
of this lead must be connected to the plug that
is situated at the bottom of the right-hand side
of the backplate unit (fig.19).
Fig.19
Note: The plug and socket can only fit one way.
Replace the cover squarely to the backplate and
guide into position so that the controls locate
correctly into the spindles while at the same
time, checking the wires are not trapped.
Should any difficulty arise, recheck the points
above.
Secure the cover temporarily in position with the
three retaining screws. DO NOT OVERTIGHTEN.
Switch on the mains electric supply to the
shower at the isolating switch.
Press the start/Stop button (fig.20). The

Power on
indicator
WARNING!
Before normal operation of the
shower, it isW-001-A
essential the following
commissioning procedure is completed
correctly.
To start the shower
Pressing the start/stop button (fig.22)
switches on the pump allowing water to
immediately flow through the unit.
To stop the shower
Press the start/stop button. This switches off
the pump and the water flow will cease.
WARNING!
If restarting immediately after
stopping, beW-003-A
aware that a slug of hot
water will be expelled for the first few
seconds.
To use the power selector
The power selector (fig.22) has four settings
— cold, low, medium and full power.
Blue symbol is for cold water only. Adjusting
the temperature control at this setting will only
increase or decrease the force of the water
from the showerhead. It will not alter the water
temperature.
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.
Red outline symbol is the low setting for extra
economy during hot months. Temperature
adjustment at this setting is via the temperature
control.
Single red symbol is the medium setting for
economy during warmer months and any
temperature adjustment at this setting is via the
temperature control.
Double red symbol is full power setting which
allows the highest flow achievable for your
preferred temperature. Temperature adjustment
at this setting is via the temperature control.

To adjust the shower temperature
The shower temperature is altered by increasing
or decreasing the flow rate of the water through
the shower via the temperature control.
After obtaining your preferred shower
temperature, the number can be remembered as
the normal setting and should only need to be
altered to compensate for seasonal changes in
ambient water temperatures.
To decrease the shower temperature
Turn the temperature control anti-clockwise
towards the lower numbers; this will increase the
water flow.
To increase the shower temperature
Turn the temperature control clockwise towards
the higher numbers; this will decrease the water
flow.
Note: Be certain 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.
WARNING!
After any servicing of mains water
supply, always flush out the pipework
to remove
any debris.
W-002-A
Always make sure the unit is started
on COLD in order to purge any air in
the pipework.
WARNING!
This appliance is not intended for use
by young children or infirm persons
unless they have been adequately
supervised by a responsible person to
W-020-A

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.
SERVICE ENGINEERS ONLY
Fig.27
Switch off the electricity supply at
the mains.
Remove the cover and disconnect the plug.
There is no need to turn off the water supply —
the act of removing the filter unit automatically
isolates the water supply.
Note: Should debris be trapped on the shut
off seat inside the valve, water will continue to
flow out as the filter is removed. It is therefore
advisable to locate the main isolating valve
before removing the filter in the event that the
unit needs isolating.
Do not rely on the filter shut off valve when
carrying out repairs or service to other areas of
the shower unit.
Unscrew the filter (fig.27) by turning anticlockwise. Remove the unit complete with the
filter and wash under running water. Make sure
all debris, etc. is removed.
Replace by pushing the unit back into its
housing until the threads engage and then
turn fully clockwise until tight. DO NOT
OVERTIGHTEN.
Before replacing the cover, it is strongly advised
to prime the unit by opening the bleed screw
until water drains from it.
Close the bleed screw and connect the plug to
the cover. Replace the cover and secure with the
fixing screws.
Switch on the electric supply and start the
shower on the cold setting only and with
the temperature control rotated fully anticlockwise.
When a smooth flow of water is obtained, the
shower can then be used in the normal manner.
