1 PLUMBING NOTES
1.1 All installations must comply with Water
Regulations or Water Bylaws.
1.2 Supply pipes must be flushed to clear
debris before connecting the shower unit.
1.3 DO NOT connect the shower unit to
the mains cold water supply as it would
damage the unit and also, the installation
would be in breach of Water Regulations.
1.4 DO NOT use excessive force when making
connections to the flexible hose or
showerhead – finger tight is sufficient.
1.5 ALL plumbing connections are to be
completed and water supplies turned on
BEFORE switching on the electricity supply.
The shower must not be operated dry
without water.
1.6 DO NOT solder pipes or fittings within
300 mm of the shower appliance, as heat
transfer can damage components.
1.7 When installed, the top of the shower unit
must be at least 75 mm lower than the
base of the cold water storage cistern to
prevent the pump being run dry without
water.
1.8 A dedicated cold water supply must be
taken directly from the cold water cistern
to the shower. This draw-off must be on
the opposite side of the cistern to the float
operated valve to reduce the risk of air
entering the unit.
1.9 The action of the pump is to increase the
flow rate. If the supply pipework cannot
handle the resulting flow rate then:
1.9.1 The anticipated flow rate may not
be achieved.
1.9.2 Air may be drawn into the hot
supply from the vent pipe causing
spluttering and temperature fluctuations at
the showerhead.
1.10 Fullway isolating valves 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. DO
NOT use stop taps or ball-o-fix type valves
which restrict flow.
2 ELECTRICAL NOTES
2.1 The installation must comply with BS 7671
‘Requirements for electrical installations’
(IEE wiring regulations). Make sure the
incoming hot and cold water supplies to
the shower are adequately earth bonded.
2.2 DO NOT turn on the electrical supply
until the plumbing connections have been
completed. Only then can the electricity be
switched on in order to power the solenoid
to turn water on to the shower when
commissioning. The shower must not be
operated dry without water.
2.3 The mains supply must be 230/240V, at
50Hz, connected to the unit via a double
pole switched 3 Amp fused connection
unit (not supplied) with a minimum 3 mm
contact separation gap in each pole.
2.4 In accordance with ‘The Plugs and Sockets
etc. (Safety) Regulations 1994’, this unit
is intended to be permanently connected
to the fixed electrical wiring of the mains
system.
2.5 Fuses do not give personal protection
against electric shock.
2.6 A 30mA residual current device (RCD)
MUST be installed. This may be part of the
consumer unit or a separate unit.

long and trouble free life from your shower
IMPORTANT: All plumbing connections must
be completed BEFORE making the electrical
connections.
Please read through the whole of this book
before beginning your installation.
IMPORTANT: The fittings on the pipe inlet
elbows are of the 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 fittings can be used with
copper and plastic pipe.
Where chrome plated pipe is used, remove
the first 25 mm of plating.
Note: The pump inside this product is rated
15 minutes on / 45 minutes off duty cycle.
SAFETY WARNINGS
a. DO NOT insert fingers into the push-in inlet
fittings. Doing so could cause injury.
b. Under no circumstances must this product
be connected to mains cold or hot water
supplies. Failure to comply will invalidate
the guarantee.
c. The shower MUST NOT be used if
suspected of being frozen.
d. The outlet of this appliance MUST NOT be

Hot water temperature
Maximum temperature 65°C.
BS 6700 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 effects of scale in hard water areas.
Temperature control
To obtain the maximum performance, this unit
should be installed, operated and maintained
as instructed in this book. The full performance
specification as below for the unit is achieved
with a blend set between 35°C – 40°C and
supplies of 15°C cold and 65°C hot with
nominally equal pressures.
1. The blended water temperature is maintained
within 2°C with a 10°C change in the hot
and cold water supply.
2. The sensor effects a shut down to seepage in
about 2 seconds if the cold supply fails.
3. Shut down to seepage is achieved even if
the hot supply is only 12°C above the blend
temperature.
4. The blended water temperature is maintained
within 1°C when the pressure between inlet
and outlet is halved (defined as a pressure
loss ratio of 2:1) on either the hot or cold
side.
Maximum static inlet pressures
100 Kpa (1 bar) or 10m (supplies must be
gravity fed at nominally equal pressures).
Minimum static inlet pressure
0.75 Kpa (0.0075 bar) or 75mm (required to
prime the integral centrifugal pump).
Maximum supply head 10m.

Fig.3 illustrates all the incorrect connections that
must be avoided.
All pipework to the shower unit must be routed
where it remains below the level of water in
the cistern. In the case of horizontal sections
of pipework in lofts, it may be necessary to
fit automatic air vents at high points on the
supplies to remove the possibility of air locks.
For the operation of the shower only, it is
recommended that the cold water storage
cistern is capable of holding at least 114 litres
(25 gallons). Where other hot and cold outlets
are likely to be in use simultaneously, the storage
capacity should be increased to 228 litres (50
gallons) in accordance with BS 6700.
Do ensure compliance with the Water
Regulations/Bylaws.
DO NOT connect to a combination cylinder
unless there is a guaranteed 114 litre cold supply
to the cylinder as the shower can deliver up to
14 litres per minute. It is advisable to check that

SITE REQUIREMENTS
Water
The installation must be in accordance with
Water Regulations/Bylaws and BS 6700.
For correct operation of this shower unit, both
hot and cold water supplies to the appliance
must be gravity fed, at nominally equal
pressures, from a cold water storage cistern and
a hot water storage cylinder.
The water circuit should be installed so that the
flow is not significantly affected by other taps
and appliances being operated elsewhere on the
premises.
Fig.2 shows a recommended installation where
the hot water supply for the shower is made
via a tee connection on the underside of the
horizontal section of pipework from the cylinder.
Alternatively, the connection can be taken from
the hot supply pipe to other outlets as long as it
is the first draw-off below the ventilation pipe tee.

the infill rate from the float operated valve meets
the output requirements..
It is recommended that there is a minimum
of approximately 114 litres (25 gallons) of hot
water storage per appliance.
The shower MUST NOT be connected to the
mains cold water supply.
DO NOT use jointing compounds.
GENERAL INSTALLATION NOTES
1. DO NOT take risks with plumbing or
electrical equipment.
2. DO NOT install this unit in a position where
it could become frozen.
3. Isolate electrical and water supplies BEFORE
proceeding with installation work.
4. Shower control MUST be fed from a cold
water storage cistern and hot water cylinder
that provides nominally equal pressures.
Fig.3 (Diagrammatic view
not to scale)
5. The unit must be mounted onto the finished
wall surface (on top of tiles).
DO NOT tile up to the unit after fixing to
the wall.
6. If installing with rear inlet supplies, it is
recommended the supply pipework is sealed
to the wall so as to prevent water from
leaking back into the wall.
7. In solid wall installations, the supply
pipework should be housed within
ducting in order to allow some free lateral
movement when making connections and
to ensure compliance with requirements of
accessibility of pipes and pipe fittings.

SITING OF THE SHOWER
IMPORTANT: If fitting to a tiled wall, always
mount the unit on the surface of the tiles.
NEVER tile up to the unit.
Refer to fig.5 for correct siting of the shower.
Position the unit vertically where it will NOT
be in direct contact with water from the
showerhead.
Note: Allow sufficient room between the ceiling
and the shower unit to access the top cover
screw.
Position the shower and showerhead on the wall
so that all controls can be comfortably reached
when using the shower.
The showerhead and riser rail can be positioned
either side of the shower unit.
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 25mm 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
or shower tray, then a device must be fitted to
prevent back-flow.

REMOVING THE COVER
To remove the cover, first pull off the cover trim
from the temperature control (fig.6) and undo
the retaining screw. Pull off the temperature
control.
This will reveal the maximum temperature stop
(fig.7). This should be left in position.
Note: If adjustment of the maximum
temperature stop is required, refer to section
’Adjusting the maximum temperature stop’.
Remove the two cover fixing screws – top and
bottom (fig.8).
Carefully lift the cover away from the backplate.
Lay aside the cover and screws until the unit is
fully installed.
Note: When removing the cover for future
maintenance purposes, be aware of the lead
connected to the PCB unit. Carefully pull off the
lead from the PCB.
DO NOT let the cover dangle by the lead.
PLUMBING CONNECTIONS
Plumbing to be carried out before wiring
Note: The outlet of the shower must not be
connected to anything other than the hose and
showerhead supplied.
DO NOT use jointing compounds on any pipe
fittings for the installation.
When connecting pipework avoid using tight
90° elbows. Swept or formed bends will give
optimum performance.
Isolate the mains water supply to the cold water
cistern. Drain the hot and cold pipes by opening
all taps.
The hot water supply can be taken from the hot
supply pipe from the cylinder. Make sure that it
is the first draw-off below the ventilation pipe
tee in order to minimise the effects of water
draw-off elsewhere in the house (see fig.2).
Note: There must not be any other draw-offs
between the take-off point and the shower.
A dedicated cold water supply must be taken
directly from the cold water cistern to the
shower. This draw-off must be positioned 25mm
below the cold feed connection to the hot water

cylinder on the opposite side of the cistern
to the float operated valve (see fig.2). This
minimises air ingress into the pipework.
Plumbing options other than those outlined
in these fitting instructions could impair the
performance. For example, if hot and cold
connections are made after draw-off points
to other outlets, (eg. washing machine, taps,
etc.) it could result in unstable flows and
temperatures should other appliances operate at
the same time.
Run the hot and cold pipework to the shower
position, making sure that the pipework does
not rise above the level of water in the cold
cistern at any point to avoid air locks. Under
normal site conditions 15mm pipework will be
adequate.
Decide the position of the shower. Cut the
pipework to the dimensions relevant to the
chosen direction of water entry into the shower.
IMPORTANT: For rear entry only, the supplied
elbows must be used. For ease of installation,
the backplate area adjacent to the top pipe
inlet must be cut out, including the top left
wall fixing hole.
When fitting the elbows to incoming pipework,
ensure the elbow collets are fully engaged with
the pipe.
Dimensions are shown in fig.9 and fig.10.
Note: The pipe inlets are marked for hot and
cold connections – left-hand side for hot inlet on
bottom entry (fig.11), but right-hand side for
hot inlet on top or rear entry (fig.12).
IMPORTANT: The fittings on the inlet elbows
are the 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
fittings can be used with copper and plastic
pipe.
If using chrome plated copper pipe, remove
the first 25mm of plating completely from the
connecting surfaces. If not completely removed
then the collet will not grip the pipe and
under pressure the pipe may be forced out.
Note: Pipework must be clipped or fixed to the
wall so that it cannot be moved or removed
without the aid of a tool.
