2.1 HOW THE SHOWER WORKS
2.1.1 When the user starts the shower by
pressing the start/stop button, the flow
control lets in the water. If there is sufficient
water pressure, the pressure switch will turn
on the heating elements.
2.1.2 The element in the tank will start to
heat the water and this takes typically 10-20
seconds.
2.1.3 By controlling the flow rate of water
over the heating elements, it will be warmed
up to the correct temperature. Reducing
the flow rate will increase the water
temperature and vice versa.
2.1.4 The following variables can affect
the shower temperature once it has been
set:Incoming water temperature.

Notes:1. Cable selection is dependent on de-rating factors, see 4.2.19.
2. In certain installations the combination of low voltage and extended cable lengths may result in loss of power and a consequential
reduction in flow rates.
3. Above cable sizes are the minimum acceptable sizes. Sizes greater than thse shown above may be used and should be used if cable
runs are greater than indicated (above cable runs are based on a maximum 9.6V drop).
4. Rewirable fuses are not recommended and are not covered by this table.
5. Installation should be carried out by a qualified person. Please refer to BS7671 (Wiring Regulations) if in doubt.
6. A 16mm² cable may be required for long cable runs. This should be used for rear entry applications only.
4.2.15 Where shower cubicles are located
in rooms other than bathrooms, any socket
outlet in that room must be situated at least
3 metres from the shower cubicle and be
protected by a 30mA RCD.
4.2.16 The current carrying capacity of the
cable must be at least that of the shower
circuit protection - see table A.
4.2.17 To obtain full advantage of the power
provided by the shower, use the shortest
cable route possible from the consumer unit
to the shower.
4.2.18 The shower circuit should be
separated from other circuits by at least
twice the diameter of the cable or trunking.
4.2.19 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 e.g.
increase from 6mm² to 10mm².
4.3 SITING CONSIDERATIONS
CAUTION
4.3.1 The shower unit must not be
positioned where it will be subjected to
freezing conditions.
4.3.2 The shower must be mounted on a
flat and even finished wall surface on top of
tiles (when applicable). Do not tile up to the
shower unit after fixing to the wall. The
shower is spaced off the wall by integral
pillars to allow air circulation.
4.3.3 Three plastic spacers are provided
which can be used when the wall is uneven.
Spacers are taped to the inside of the cover.
4.3.4 Do not use sealants around the
shower.
4.3.5 Position the unit where it will NOT be
in direct contact with water from the spray
head. Position the shower unit vertically.
4.3.6 Water
Regulations/Bye-laws
(shower hose connections) requires the
spray head to be ‘constrained by a fixed or
sliding attachment so that it can only
7
discharge water at a point not less than
25mm 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 spray head can be placed within a
bath, basin or shower tray, then to prevent
back-syphonage an alternative method
should be used, such as a check valve in the
supply pipe.

4.4 PRESSURE RELIEF DEVICE (PRD)
Lowest position
4.4.1 To meet European standards the
shower unit has an integral Pressure Relief
Device (PRD) . The PRD provides a degree
of shower unit protection should an
excessive build-up of pressure occur within
the shower.
4.4.2 DO NOT operate the shower with a
damaged or kinked shower hose or blocked
spray head, as this can cause the PRD to
operate. Failure to follow this instruction will
invalidate the warranty on this item.
4.4.3 When commissioning follow the
procedure described in section 6.1. Failure
to do so may result in the operation of the
PRD. Failure to follow this instruction will
invalidate the warranty on this item.
4.4.4 The shower must be positioned over
a bath or shower tray because in the event
of the PRD operating, water will drain from
the bottom of the shower.

positioned on the fixing screws between the
wall and the shower unit. The shower unit
must not be twisted or deflected in any way.
5.3.1 The most convenient stage at which
to mount the shower on the wall will depend
on the installation and the cable and pipe
entry options selected. This will normally be
when cable and pipe runs have been
completed.
5.3.2 To obtain accurate drilling positions
for the 3 mounting holes either:1. Use template supplied.
2. Connect shower to water pipe and mark
the 3 holes.
WARNING
5.3.3 Before drilling any holes, check

enclosed in suitable plastic trunking.
5.4.5 Where both pipe and cable are
arranged for top or bottom entry, the pipe
should be on top of the trunking as shown in
fig. 10.
5.5 PIPE ENTRY
For pipe entry options see page 10.
5.5.1 An inlet plug should be removed
from the chosen inlet port - see fig. 8.
5.5.2 Concealed rear entry is considered
the neatest option.
5.5.3 For concealed rear entry, solder ring,
end feed or compression fittings are suitable.
5.5.6 Prior to fixing the shower unit, ensure
the pipe end is clean and slightly lubricated.
Silicone based lubricants or petroleum jelly
are suitable.
5.5.7 Chromed pipes must have the
chrome plating removed from the length of
pipe that enters the showers plastic inlet
connector.
5.6 PLUMBING
5.6.1 Decide where to connect to the water
mains for the feed to the shower. Ensure
that the pipe you have selected is not a gas
pipe (they can look similar) or a hot water
pipe.
5.6.2 Cut the necessary pipework to length,
assemble and offer up to the installation
before making any soldered joints. Ensure
that the pipe is the correct length, since to
shorten it can be difficult once the joints
have been made.
5.6.3 Carry out any cutting with pipe cutters
in preference to a hacksaw, to minimise
swarf and burrs.
5.6.4 Remember to incorporate a servicing
valve and if required, a check valve.
11
5.6.5 Locate the stop cock and turn off the
water supply. Check that the pipe you
intend tapping into no longer carries water
by opening a tap that the pipe supplies.
5.6.6 Make the connection to the pipe. If it
is on a low-lying loop, there may be some
water left in the pipe, so be prepared for
some flow of water. Make all joints except
that to the shower before flushing.
5.6.7 It is essential to flush the system
before the shower is connected in order to
clear any debris, bits of solder and swarf
which could enter and damage components
within the shower, see fig. 13.
5.7.4 Strip the outer insulation back as
shown in fig. 14. The protective cover
indicates the position for 10mm cable
insulation and the minimum position for all
cable sizes.
Fig. 14 Cable insulation length
Fig. 13 Flushing pipework
5.6.8 Check for leaks in all pipework and
rectify as necessary.
5.6.9 Do not use jointing compound on
any pipe fittings for the shower installation.
5.6.10 Carry out all soldering on the pipe
run to the shower before the shower is fitted.
5.7.5 Cut the live, neutral and earth wires
to length and strip insulation from the live
and neutral wires leaving 15mm maximum
bare wires. Add suitable green/yellow
sleeving to earth cable leaving 10mm
maximum bare cable.
5.7.6 Connections
Red or brown to live

Ensure that all terminal block screws are
tight, failure to do so will result in overheating.
5.8 FITTING THE COVER
5.7 WIRING
5.7.1 Remember, before working on
electrical components, ensure they are
not live. If in any doubt, switch off at the
main switch at the fuse board or consumer

5.8.1 When the cable and pipe
connections have been made and the
shower screwed to the wall, the cover may
need to be cut to suit cable/pipe entry
positions.
5.8.2 The cover has thinned wall sections
at the designated top and bottom cable and
pipe entry positions, no cutting is required
for rear cable and rear pipe entry.
5.8.3 Very carefully cut the cover only at
the designated positions using a junior
hacksaw or side cutters. Always finish using
a round file. Check that the cover fits over
cables and pipes without interference.

5.8.7 Refit the flow control knob. To ensure
correct location, the finger grip must be
horizontal and pointing to the cold position
(9 o’clock), see fig. 16. Ensure the flow
control knob is pushed fully home and ‘snaps’
into position.
5.8.8 Turn the knob clockwise 180° (to 3
o’clock) and ensure it has smooth
movement. If resistance is felt the knob may
be fitted incorrectly.
6. COMMISSIONING
CAUTION
Follow the commissioning procedure
exactly as failing to do so could result in
damage to the shower and may void the
guarantee.
6.1.1 Once you have finished installing
the shower, carry out the following tests to
ensure that the shower is functioning as it
should.
6.1.2 Set flow control knob to 12 o’clock
position.
6.1.3 Without fitting the shower head
secure the hose at low level where the water
can discharge safely. With the electrical
power turned OFF and the water supply to
the unit turned ON, press the stop/start
button until water runs through and out of
the open hose, then after a few seconds turn
the shower off. The handset may now be
fitted.
6.1.4 Turn on the electrical isolating switch.
Press the stop/start button.
6.1.5 Slowly turn the flow control knob into
the red sector. The elements should now be
heating.
6.1.6 The temperature of the spray should
now increase.
6.1.7 Adjust the flow control knob to give
the desired temperature. Allow a few
seconds after each adjustment for the
temperature to stabilise. A cool shower can
be obtained at the extreme end of the blue
sector.
6.1.8 The temperature obtained will
depend on the incoming water temperature.
7. OPERATOR INSTRUCTIONS
7.1 TO TURN ON & SET TEMPERATURE
7.1.1 Turn on the electrical isolating switch.
7.1.2 Press the stop/start button.
7.1.3 Turn the flow control knob.
7.1.4 Make adjustments carefully. Give
the shower a few seconds after each
adjustment to stabilise, then check the
temperature by hand before stepping into
the shower.
13
7.2 TO TURN OFF
7.2.1 Press the stop/start button.
7.2.2 Turn off the electrical isolating switch.
NOTE
7.2.3 For safety purposes, this shower has
a phased shut off. Water will continue to run
for a few seconds after switching off to
dissipate any residual heat from the heat
exchanger.
5. Withdraw filter element, inspect and
clean.
6. Refit filter element and protective cover.
The protective cover must be under the
cable.
7. Refit cover - refer to 5.8.
8. MAINTENANCE
8.1 CLEANING THE HANDSET
8.1.1 To maintain performance from the
shower, the handset must be cleaned
regularly, maybe as often as once a week in
hard water areas. This is because fine
holes can become restricted with scale and
this will affect the pattern of the spray and
cause the shower to perform poorly.
8.2 INSPECTION
8.2.1 We recommend that in the interest
of safety, the shower and its electrical
installation is checked by a qualified
electrician at least every two years.
8.2.2 During inspection check that all
electrical connections are fully tightened
before replacing the cover, as loose
connections may cause overheating of the
terminals and product failure.
8.3 CLEANING THE FILTER
Only to be carried out by competent person.
8.3.1 To remove filter :1. Turn shower electrical isolating switch
OFF.
2. Turn water servicing valve OFF.
3. Carefully remove badge using small
screwdriver and undo cover retaining
screw, pull cover away complete with
knob, from the top and lift off - see fig. 8.
4. Unscrew the two screws at the side of
the protective cover - see fig. 17.

9. FAULT FINDING
9.1 TROUBLESHOOTING
9.1.1 In the unlikely event of a problem,
consult the troubleshooting chart.
9.1.2 For the particular symptom follow
the suggested remedies in the order given.
9.1.3 IF YOU ARE UNABLE TO REMEDY
THE PROBLEM WITHOUT REMOVING
THE COVER, YOU SHOULD CONTACT
YOUR INSTALLER OR A QUALIFIED
ELECTRICIAN.
9.1.4 Where the fault cannot be corrected
by yourself or your installer, DO NOT
REMOVE UNIT FROM THE WALL, but
contact Customer Service Department who
will try to help over the telephone. If
necessary, they can arrange a visit by a
service engineer. We find that the vast
majority of problems can be solved by
reference to these fitting instructions or by
discussion over the telephone. In the event
that an engineer is called and the fault is
caused by faulty installation, usage, or lack
of reasonable maintenance, a call-out
charge will be made.
9.1.5 This shower is not suitable for use in
commercial applications. Such use would
invalidate warranty.
