The Electrical Installation and Circuit Protection of this
shower must comply with current I.E.E Wiring Regulations
(BS 7671) and Building Regulations (Part P). We
recommend that this product is installed by a qualified
electrician prior to use. The following notes are for
guidance only.
Important: You must switch o the power at the consumer
unit, isolate the electrical circuit and verify the earth before
making any electrical connections.
The shower must only be connected to a 230-240V AC
supply. The electrical rating of your shower is on the pack or
on the rating plate label.
The shower must be connected to its own independent
electrical supply. It must not be connected to a ring main,
spur, power socket,
or lighting circuit.
If you don’t have a spare fuse way or the rating at the main
fuse box is below 80A, you should seek advice from an
electrician and may need a new consumer unit - specifically
for the shower.
A separate and permanently connected cable must be taken
from the consumer unit directly to the shower via a 45 Amp
double pole switch with a minimum contact separation gap
of 3mm in live (L) and neutral (N) poles.
The isolating switch can be a ceiling mounted pull cord
switch within the bathroom or wall mounted in an adjacent
room. The power switch must be easily accessible and
identifiable as the supply to the shower.
Note: Voltage drop in the supply to the premises, due to
heavy local demand, will aect the performance of your
shower. To gain the optimum power possible from this
shower unit try to find the shortest possible route from the
consumer unit to the shower to run your cable.

Electrical Requirements

It is a requirement that a residual current device
(RCD) formerly known as an earth leakage circuit
breaker (ELCB) with a tripping current of 30mA, is
incorporated in the circuit. This may be part of the
existing consumer unit or a separate unit.
For close circuit protection DO NOT use a rewireable
fuse. Instead use a suitably rated Miniature Circuit
Breaker (MCB) or Cartridge Fuse.
Please refer to the Circuit Protection Table.

Note: Cable selection is dependant on derating factors
On installation of the appliance the impedance
measurement of the Neutral and Earth back to the supply
source is to be less than 1.0 Ohms. This is in line with the
general installation requirements of the UK Network and
will generally present no problem within the UK Network.
In domestic installations you must ensure that the
electrical supply and existing fuse board are adequately
rated.
Do not turn on the electrical supply until the plumbing
has been completed and the shower cover re-fitted.

If the shower is to be installed in a hard water area, we
recommend that an in-line scale inhibitor is fitted which will
prolong the life of the shower. Please refer to your supplier
for advice.
Warning: The shower must not be installed in
an area subject to freezing conditions. Do not use
if you suspect the shower is frozen, this will
damage the shower unit.
The shower must be connected to a mains water supply
only with a minimum working inlet pressure of 0.07MPa
(0.7bar) at a minimum flow rate of 8 litres per minute. The
maximum static inlet pressure must not exceed 1.0MPa
(10bar).
If it is intended to operate the shower at pressures above the
maximum stated, a suitable pressure reducing valve (PRV)
should be used.
Water regulations stipulate that the showerhead be
‘constrained by a fixed or sliding attachment (hose retainer)
so that it can only discharge water at a point not less than
20mm above the spill over level of the bath or shower tray
or other fixed appliance’.
If a showerhead can sit within a bath, basin or shower tray,
you must fit a double check valve in the supply pipe work
to prevent back siphonage. If the showerhead can sit within
a WC then the air gap should be a type AUK3 not less than
20mm or twice the diameter of the inlet pipe to the fitting,
whichever is the greater.
This fitting needs to be installed in accordance with the
following Installation Requirements and Notes (IRN) to
ensure they meet the requirements of the Water Supply
(Water Fittings) Regulations 1999 and the Scottish Bylaws
2004.
The fitting shall be installed so that its outlet discharges
above the spill-over level of any fixed appliance as indicted
on the illustration below.
For backflow protection in premises or installations up to,
and including Fluid Category 3 and 5.
The vertical distance of the outlet above the spill-over level
shall be not less than 20mm or twice the diameter of the
inlet pipe to the fitting, which ever is the greater. If the fitting
cannot be installed as indicated it shall be installed with
a backflow prevention arrangement suitable for the Fluid
Category.

Warning: The outlet of the shower acts as a vent
and must not be blocked, restricted or connected to
any tap/closure device other than the handset
supplied.
Do not solder within 300mm of the shower unit or allow
solder or flux to fall onto the casings.
Important: An additional independent stop valve complying
with the current water regulations must be fitted in the
mains water supply as a means of isolating the supply to the
unit for servicing and/or maintenance work.
It is essential that all pipe work is flushed through to remove
debris and swarf that could otherwise damage the unit.
Once the pipe work has been flushed through, turn o the
water supply at the stop valve.
Connect the mains water supply to the inlet port of the
shower using 15mm copper pipe (BS EN1057) or 15mm
plastic pipe (with insert).
Do not use stainless steel pipe work. If using chrome plated
pipe ensure that the first 25mm of plating is carefully
removed to allow push-fit fitting to grip the inlet pipe.
Inlet Entry Options
The pipe work can enter the shower unit from 6 dierent
positions.
Bottom left, Bottom right, Top left, Rear left, Rear right or
Rear left - using an elbow (as shown on page 11).
To top or bottom left positions
The shower unit should come supplied with the inlet
connection set for a bottom left position. To change it to
a top left position: swivel the inlet connector elbow from
facing downward to facing upward.
To bottom right position
Unfasten the screw (3) securing the inlet connector elbow
clamp (4), remove the tab from the slot and keep until the
inlet pipe is repositioned. Lift the outlet connection (5) up
out of the way from its position at the bottom of the unit.
Pull the inlet connector elbow towards you and over to the
right hand side with the inlet entry point facing down. Refit
the clamp tab (4) into the slot on the right, refasten the
screw (3) and replace the outlet connection (5).
To rear entry positions
Swivel the inlet connector elbow to face a rear entry pipe
connection.

Hole Cover Fitting
Top left entry: Depending on your choice of cold-water
entry direction, you may need to remove thin areas of plastic
cover to facilitate pipe work entry down through the top left
of the unit.
Bottom entry: Depending on your choice of cold-water
entry direction, fit ‘hole covers’ to the pipe work slots at the
bottom of the unit.
Note: The grey areas shown are tabs that can be removed to
allow 6mm cable entry only.
Water Connection
The inlet pipe connection into the elbow is a self-seal push-
fit type. All burrs and rough edges must be removed from
the end of the pipe before connecting.
To release the pipe work from the push-fit type fitting, press
and hold the collet against the elbow and pull the pipe out
of the elbow.
Turn on the water supply and inspect for water leaks at the
shower inlet. Once inspected-turn o the water supply.
Pressure Relief Device (PRD)
A pressure relief device is designed into this shower.
The pressure relief device provides protection should an
excessive build up of pressure occur within the shower
unit. It is advisable to position the shower unit over a bath
or shower tray in the unlikely event the device should
discharge.
Do not use the shower with a damaged or kinked shower
hose or blocked handset. This may trigger the PRD which
will discharge through the vent in the bottom right hand
corner (shown).
In the event of the PRD activating, water will be discharged
from the vent. If this happens, switch o the electricity
and water supplies to the shower and contact Customer
Services.

Fitting the Riser Rail
Before proceeding with fitting the rail, identify each of the
items supplied using the illustration on the right.
The Slider should not be removed from the rail during fitting.
The underside of the slider has a button to release the slider
and allows the height to be adjusted.
Slide the soap dish onto the bottom end of the rail. Position
a wall bracket onto each end of the rail, ensuring the hole
through the top of the rail lines up with the hole in a wall
bracket.
Position the rail on the wall, bearing in mind the dierent
heights of people likely to use the shower and the length of
the hose when connected to the shower and passed through
the retaining hole in the soap dish. Mark the wall to indicate
the upper fixing screw position.
Warning: Please check for any hidden pipes and
cables before drilling holes in the wall.
Tips:
A piece of insulation or masking tape positioned where
holes are to be drilled and before marking out the exact
position for the fixing holes will help stop the drill bit
from wandering, particularly on a tiled surface.
When working near a basin, bath or shower insert plug
or cover waste to prevent losing small parts.
Take care not to drop tools/equipment into basin, bath
or shower during shower installation.
Drill the wall at the marked fixing position to suit the wall
fixings to be used, loosely fix the rail (with the large hole
on the side shown) and wall bracket. Check that the rail is
hanging vertically using a spirit level.
Slide the lower wall bracket onto the rail and mark its
required position onto the wall.
Note: The lower wall bracket does not fix to the riser tube
and can be positioned along the riser tube so as to cover
either an existing riser hole in the wall or over a tile joint.
Remove the lower bracket from the rail and unscrew the
upper bracket from the wall. Mark and drill the lower wall
bracket fixing position and fix the bracket to the wall. Slide
the rail down through the lower wall bracket and reattach
the upper bracket.
Check that the rail is perfectly vertical and tighten the upper
fixing screw. Insert end caps into the wall brackets at both
ends of the rail.
When fitting the hose, it should pass through the larger hole
of the soap dish.
Note: The conical hose end and not the handset handle, fits
into the slider. Ensure the washer is fitted between the hose
and the handset handle. The slider moves more freely on the
rail if gripped next to the rail, rather than at the handset.

Fixing Your Riser Rail to the Wall

Warning: Before using the shower for the first
time, it should receive a final flush through to
remove any remaining debris that may be in the
pipe work or hose and to ensure the heater unit
contains water before the electrical elements are
switched on.
Remove the showerhead from the hose and if not already
attached, attach the hose to the outlet port and ensure that
the outlet hose mesh filter is fitted. The power control knob
(2) must be switched
to the cold ( - 9’oclock) position ‘blue’ (heating elements
will not be on).
The temperature control knob (3) must be set fully
clockwise to minimum flow. (This is to prevent the PRD
activating when water is first turned on).
Turn on the water supply and inspect for water tightness.
Turn on the mains electrical supply to the shower.
Press the STOP/START button (1), wait approximately 30
seconds for the water to flow correctly. Once the water
has flowed for a further 10 seconds, rotate the temperature
control knob (3) from the fully clockwise position to the fully
anti-clockwise position. Repeat this procedure several times
until a continuous flow of water (with no air bubbles) is
obtained from the shower hose.
Once you are satisfied that the system has been flushed
through thoroughly, press the STOP/START button (1) to
stop the flow.
Important: Isolate the electrical and water supply to the
unit. Clean the Inlet Filter and Outlet Hose Mesh Filter to
remove any debris from the flush - see Maintenance Section.
Note: If the letters LP appear on the front
panel just above the STOP/START button (1)
this indicates too low a water supply pressure
to the unit. Please switch o unit until water

Commissioning - Testing the System

Please ensure the commissioning procedure has been carried
out.
If you did not fit this shower yourself and you are about to use it
for the first time, check with the installer to ensure he or she has
run the commissioning procedure as described on page 18.
To Start the Shower
Press the STOP/START button (1).
The light around the STOP/START Button will flash as the water
heats up. Once the light stops flashing and stays on, the shower
has reached your selected temperature and is ready to use.
During periods of high ambient temperatures (e.g. hot summer
days), it may be necessary to select a lower power setting in
order to achieve your ideal shower temperature.
It is always advisable to test the water temperature with your
hand before stepping under the shower. Please note that there
is always a delay of a few seconds between you selecting
a temperature setting and the selected water temperature
starting to flow.
ThermoSafe™ Operation: When the shower is started, it will
wait a short time for the shower outlet temperature to stabilise
to establish the user’s desired water temperature. The shower
will then monitor the water temperature and adjust the heating
power to compensate for rises in temperature, resulting in safe
showering temperatures.
If the user adjusts either the Power Control or Temperature
Control, the shower will again wait for the user’s new desired
temperature to stabilise. The shower will then resume its
monitoring and compensation of water temperature.
When adjusting the temperature, including during first start
up, do not rapidly turn the dial to Max Temp to increase the
temperature. Instead, use small changes and wait for the
new temperature to settle before changing again.

To Stop the Shower
Press the STOP/START button (1).
Phased Shut Down: When the shower is
turned o, water will continue to flow and the
light around the STOP/START Button will flash
for a short period while the heater cools down
to approximately 30’C, before automatically
turning o. This ensures the shower is ready
for the next user and helps reduce the build-up
of limescale in the heater.
Do not use the isolation switch (pull cord) to
stop the shower, use the STOP/START button

Performance Maintenance Indication
Display shows “CL”. This is a performance Maintenance
Indication that routine service cleaning is advisable to
maintain showering performance. Follow the instructions to
Clean the Showerhead, Clean the Inlet Filter and Clean the
Outlet Hose Mesh Filter.
Cleaning the Showerhead
Your Bristan showerhead has a rub-clean pad for easy
cleaning. Simply rub your fingers across the rubber spray
jets regularly and before you turn the shower on to remove
any scale or debris.
The hardness of the water in your area will determine how
often
you should clean your showerhead. Build up of scale in
particularly hard water areas combined with constant use
means you may need to clean your showerhead once a
week. To ensure continued performance of your electric
shower the showerhead needs to be regularly descaled.
