Important Safety Information

For correct operation of the Bristan Thermostatic
Power Shower both hot and cold supplies to the unit
must be gravity fed, at nominally equal pressures,
from a cold water storage tank and hot water
storage cylinder.
Please ensure compliance with all Water Regulations.
Please ensure maximum supply head of 10 metres
(1 bar), minimum 1 metre (0.1 bar).
Please note, when using this unit in ‘gravity’ shower
mode, without the boost button depressed, ensure
you have a minimum of 1 metre head from your
shower head to the bottom of your cold water tank.
It is recommended that the hot water supply is at a
temperature of 60°C, in line with British Standard
6700, British Water Regulations, and Plumbing Code
of Practice.
Before proceeding with the installation of this unit,
check that your site requirements allow the shower
unit and handset when positioned on the wall to be
a minimum of 1 metre below the cold water storage
tank.
The unit can be connected to a cylinder system
providing it has cold water storage capacity of 112
litres (25 gallons).
Do not run shower dry as this will damage the
internal seals and invalidate the warranty.
All pipe work into the unit should be 15mm. Non-
restrictive isolating valves must be fitted on hot and
cold supply pipes. When connecting pipe work avoid
using elbows: sweep or formed bends will ensure
optimum performance.
The temperature of your stored water must not
exceed 65°C. A stored water temperature of
60°C is considered sucient to meet all normal
requirements in line with the British Standard 6700.

Tools You’ll Need

Please note that this product comes packaged
with the front cover and control knobs already
in place. These have to be removed to install
the shower. Please follow the procedure below.
Removing Cover
1. Temperature Control handle
2. Graphic Ring
3. Logo
4. Screws (x3)
Pull o control knob (1).
To remove the graphic ring (2) which
surrounds the main control knob, insert a thin
bladed screwdriver into the recess (arrowed)
gently prise o the ring, revealing two fixing
screws.
Remove lower logo (3) by inserting a thin
bladed screwdriver in the slot, to reveal the
lower fixing screw.
Remove all three fixing screws (4). The cover
can now be slowly removed - care should be
taken not to strain wiring which is attached to
the front cover.
This procedure can be reversed to replace the
front cover and control knob after installation
to the wall.
We recommend that the shower unit is fitted
at chest height, and set to one side of the
intended riser rail position, ensuring that the
top of the shower unit is at least 1 metre below
the base of the cold water storage tank.
The outlet connection for the hose should be
sited at the bottom of the unit.
The integral fittings on the valve are of the
self-seal push-fit type. Ensure that all burrs are
removed from the ends of the supply pipes.
Where chromium plated pipe is used then the
first 25mm of chrome must be roughened or
removed to ensure that the push fit fittings in
the supply retain the pipe in position.
The inlet elbows supplied are of a standard
length, in some cases these will need to be
shortened for correct installation.

Prior to Installation
IMPORTANT
The unit must be fitted on the
finished tiled surface.
Do not seal the edge of the
shower unit to the tiled surface
with any form of sealant.
The gap between the back of
the shower unit and the tiles
is needed for ventilation.
REMEMBER
Isolate mains water
and electrical
supplies before
starting installation

Side Feed
Connecting pipework can feed from above or
below the unit, or straight through the wall at
nominal centres of 40mm.
If exposed pipe work is the chosen
option, the pipes enter the unit on the
right hand side with the cold on the
top. The pipe centres are 40mm
apart, and need to penetrate the
mixer connections to a depth of 25mm.
Position the unit on the wall and mark
the fixing hole positions. Drill and secure
to wall using appropriate fixings (not supplied).
Make the necessary measurements, remove the
unit from the wall, and bring the
pipe work and wiring to finished
positions.
Make the hot water
connection into the hot
water supply pipe from
the cylinder, ensuring
that it is the first draw
o (below the
expansion tee),
to minimise the eects
of water drawn o
elsewhere in the house,
and a minimum of 1 metre
below the base of the cold
water storage tank. This should not be directly
beneath the ball valve as aeration of the water
going to the shower could cause pump damage.
If connection to the hot water storage pipe is
not possible, a cylinder flange type connection
may be used.
Make the cold water connection into the base of
the cold water storage tank, 60mm below the
level of the cold water take o to the hot water
cylinder.
Flush out the pipe work to ensure that no debris
enters the unit.
Detach the pipe entry grommet and, using a
sharp knife or similar, remove the centre (15mm
dia.) portions, and refit the grommet.
Fit the shower unit over the pipe work, and
insert the mains wiring through the aperture at
the top of the base moulding. Ensure that the
supply pipes are fully inserted into the mixer
valve ‘push fit’ connections, and fix to the wall.
Connect the wiring in line with the polarity
indications moulded into the base unit.

it should be let into the wall with
the ends of the hot and cold pipes
standing 40mm o the finished
surface of the wall, and centres 40mm
apart, with the cold above the hot. Knock out
the inlet holes in the rear of the unit.
Make the hot water connection into the hot
water supply pipe from the cylinder, ensuring
that it is the first draw o (below the expansion
tee), to minimise the eects of water drawn
o elsewhere in the house, and a minimum of 1

centred in the holes in the rear of the base
moulding, mark the fixing screw positions on the
wall and remove the unit. Drill the fixing screw
holes and secure with appropriate fixings (not
supplied).
Cut the plastic inlet elbows supplied to 40mm
long from the centre of the elbow, and remove
any burrs from the cut end. Fit the cut inlet
elbows into the push-fit connectors on the
shower mixer valve.
Connect the wiring in line with the polarity
indications moulded into the base unit.

Fixing the Riser Rail to the Wall
REMEMBER
Check for any
hidden pipes and
cables before
drilling!

Connect the shower hose to the unit but do not
fit the handset. Fit the front cover as shown in
‘Prior to Installation’.
Turn on the hot and cold isolating valves, and the
electricity-isolating switch. Place the open end of
the hose in the bath or shower tray.
Set the temperature control knob to cold, fully
clockwise, and press the ‘stop/start’ button.
Cold water will run from the hose, and you should
allow this to continue for two minutes after which
the control knob should be returned to the ‘12
o’clock’ position. Allow the water to run for a
few minutes to stabilise the hot water flow, and
then check that the water is at a comfortable
showering temperature.
If it is too hot or cold, turn o the electricity-
isolating switch, pull o the control knob, and
adjust the brass spindle anti-clockwise to increase
the temperature, clockwise to decrease. Replace
the knob in the ‘12 o’clock’ position, switch the
electricity on, and check the water temperature.
Readjust as necessary until a satisfactory
temperature is achieved.
Pass the shower hose through the hole in the
soap dish and, using the rubber sealing washer
supplied, fit the handset to the hose and place
the handset in the handset holder.
Press the Stop/Start button. Water flows from
the shower head under the gravity pressure from
the storage tank. The ‘Eco’ button allows you to
switch from a power shower to a gravity (non-
powered) shower.
Temperature Adjustment
Temperature Adjustment
The valve allows the maximum showering
temperature to be set at a safe level,
preventing accidental scalding. This setting
should be made during commissioning and
will require that the hot water cylinder is at its
normal operating temperature.
IMPORTANT:
The handset must be in the spray mode.
We recommend the reading of User
Instructions before proceeding further. This
will familiarise you with the operation of the
shower.
Turn the brass mixer valve spindle fully
clockwise, and then anti-clockwise until the
black line on the spindle is aligned with the
groove on the mixer body, and fit the control
knob in the fully cold position. Check that it is
correctly fitted by turning fully clockwise to
the stop, pull the knob o and check that the
black line and groove are aligned. Adjust if
necessary. This sets the shower temperature
to 38-40°C, with the control knob pointing
to ‘12 o’clock’, if the stored hot water is at the
recommended 60°C.

Cleaning
Do not at anytime use bath cleaning liquids, powders or
specified scratch cleaners on any surface finishes. In order to
avoid surface wear or chemical attack on any of your shower
fittings when cleaning, always use a damp cloth. For persistent
stains or marks, you may use domestic liquid or soap.
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.
