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.

Water Requirements
IMPORTANT
Under no circumstances

connections are undertaken.

The shower must only be connected to a
230/240V AC electrical supply, from a 13-amp
ring main; via a fused double pole switch with
at least 3mm contact separation.
A manual switch is to be clearly identifiable,
with a minimum distance of 2.5m from a fixed
tap or shower, i.e. mounted in an adjacent
room or via a ceiling-type pull cord.
It should be fused at no more than 3 amps.
This appliance must be earthed, and all
associated metal pipe work earth crossbonded
in line with current I.E.E. regulations.
Please use the cable entry point provided.
Failure to comply will eliminate any BEAB

Product Features

To operate the shower ensure the
temperature control knob (1) is set
approximately to the 12 o’clock position
and press the Stop /Start button (2).
Adjust the shower temperature by
turning the knob anti-clockwise -
towards red, for warmer temperature,
and clockwise - blue, for cooler.
Setting the knob in the same position
in future will give the same showering
temperature.
If a less powerful shower is required,
press the Shower Eco
button (3).
The handset holder has a friction grip
on the rail and simply slides up and
down to adjust the height. The angle of
the handset in the holder has 5, spring
loaded positions. To adjust, grip the
handset handle next to the hose nut,
and move it to it’s required position.

Specification
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.
