Water Requirements
Under no circumstances must the Power Shower be connected to
the mains cold water supply, or to a combination hot water system.
For correct operation of the Bristan 1000 Power Shower both hot
and cold supplies to the unit must be gravity fed, at equal pressures,
from a cold water storage tank and hot water storage cylinder.
We recommend a minimum 112 litre (25 gallons) cold water storage
tank. Please ensure compliance with all Water Regulations.
Please ensure maximum supply head of 10 metres, minimum 1
metre to the shower head when positioned on the wall.
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.
Do not use jointing compounds, or solder within 300mm of the unit.
Before proceeding with the installation of this unit, check that your
site requirements allow the shower unit when positioned on the
wall to be a minimum of 1 metre below the bottom of the cold water
storage tank.
All plumbing should be completed before any electrical connections
are undertaken.
The unit can be connected to a combination cylinder system
providing it has cold water storage capacity of 112 litres (25 gallons).
When connecting pipe work avoid using elbows: sweep or formed
bends will ensure optimum performance.
Do not run pump dry as this will damage the internal seals and
invalidate the warranty.
All pipe work to the unit should be 15mm. Non-restrictive isolating
valves must be fitted on hot and cold supply pipes.
Do not position unit in areas subjected to freezing conditions.
The temperature of your stored water must not exceed 65°C. A
stored water temperature of 60°C is considered sufficient to meet
all normal requirements in line with the British Standard 6700.
Warning - All connecting pipe work should be earthed.
Procedure - Plumbing Connections
Isolate mains water and electrical supplies
To empty the pipe work open the hot and cold water taps.
Make your connection into the hot water supply pipe from the
cylinder, ensuring that it is the first draw-off (below the expansion
pipe tee) to minimise the effects of water draw offs elsewhere in the
house, and a minimum of 1 metre from the base of the cold storage
tank and the top of the hot water cylinder.
If this is not possible, a direct connection must be made from the
hot water cylinder with a cylinder flange.
The cold water supply should be taken directly from the cold storage
tank, and must be positioned 60mm below the cold feed connection
to the hot water cylinder. This should not be directly beneath the ball
valve as aeration of the water going to the shower could cause pump
damage.
Run hot and cold pipe work to the unit position.

Fitting the Shower
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
position of the shower handset when positioned on the wall is at
least 1 metre below the cold water storage tank.
Important: The unit must be fitted on the finished tiled surface.
Warning: 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.
The outlet connection for the hose should be sited at the bottom of
the unit.
Do not fit a fuse or switch on mains electrical supply until all
plumbing work is completed. Connecting pipework can feed from
above or below the unit, or straight through the wall at nominal
centres of 40mm.
Top Feed = Hot on the right/cold on the left
Bottom Feed = Hot on the left/cold on the right
Back Feed = Hot on the bottom/cold on the top
Procedure:
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.
Flush out the supply pipes to ensure that no debris enters the unit.
Cut the inlet elbows to the required length.
Locate the inlet elbows into the mixer valve inlets by pushing firmly
through the rubber grommets until pipe stop is felt.
Hold the unit on the wall and mark the pipe work to the appropriate
length.
Cut the pipes and remove all burrs. Push the unit and elbows firmly
onto the pipes until the stop is felt.
Mark the fixing points for the unit.
Release unit from pipes by pressing the colletts on the elbow
fittings, and pulling the unit off the pipe work.
Warning! Please check for any hidden pipes and cables before
drilling holes in the wall.
Drill the wall and insert the appropriate wall fixings.
Bring a supply cable (to conform to I.E.E. regulations) from the
switch to the unit position. The cable can enter the unit from the
rear, or via channels in the base of the unit, and the bottom or the
right hand side.
Feed the supply cable in to the unit but do not connect.

Fitting the Riser Rail
Before proceeding with fitting the rail, identify each of the items
supplied using the illustration on your right.
The Slider (1) should not be removed from the rail (2) during fitting.
The top of the slider has a smooth profile, whereas the underside
has a recess revealing the grooves on the handset holder.
Fit the soap dish (3) onto the bottom end of the rail and secure using
the small screw from the kit.
Position the rail on the wall, bearing in mind the different 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.
Drill the wall at the marked fixing position using a 6mm drill to a
depth of 35mm push the plugs (4) supplied into the hole and loosely
fix the rail end using the screw supplied (5), checking that the rail
is hanging vertically using the spirit level incorporated into the top
end of the rail. The bubble should be exactly between the two lines
on the spirit level body. Mark the position for the lower fixing screw,
move the rail to one side, drill the wall, and fix the lower end of the
rail.
Check that the rail is perfectly vertical and tighten both fixing
screws. Slide the end cap (6) into position on the top end of the rail,
and fit the screw cover (7) into the recess in the soap dish.
When fitting the hose, it should pass through the larger hole of the
soap dish.
Note: The hose nut and not the handset handle, fits into the slider.
The slider moves more freely on the rail if gripped next to the rail,
rather than at the handset.

Commissioning - Testing the System
With the front cover removed ensure the black ‘purge/shower’
switch inside the base is switched to purge. This enables water to
flow without the pump running which is necessary in the following
commissioning process.
Fit the front cover using the 3 fixing screws.
Push the temperature control knob onto the spindle with the marker
pointing to the ‘12 o’clock’ position.
Connect the shower hose to the unit but do not fit the handset.
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 fully cold (marker at ‘6 o’clock’
position) and press the ‘stop/start’ button. The pump will not operate
but the water should run.
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.
Turn off the electricity at the isolating switch and remove the knob
and cover. Switch the black ‘purge/shower’ switch to shower and refit
the cover and knob ensuring the marker on the knob points to the ‘12
o’clock’ position.
Turn on the electricity at the isolating switch.
Pass the hose through the hole in the front of the soap dish and refit
the handset.
Your shower is now ready to run. Press the stop/start button on the
front cover to operate the shower, which will work as a power shower.
It is intended that the temperature knob aligned to the ‘12 o’clock’
position you should get a comfortable shower temperature. If
however the shower is too hot or cold remove the control knob and
adjust the brass spindle anti-clockwise to increase the temperature
- clockwise to decrease. When the desired shower temperature is
achieved replace the knob with the marker pointing to the ‘12 o’clock’
position.
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 off 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.

be adjusted.
The handshower has three shower modes, which are selected by
rotating the bezel around the spray head.
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.
Handset
The Handset has three spray modes.
1. Spray
2. Massage
3. Combination
To select the desired showering mode, grip the bezel of the handset
and turn in either direction.
Cleaning - Rub-clean feature
To remove any build up of limescale from your handset, remove it
from its holder and rub your fingers over the rubber spray jets. Turn
the shower on and any build up of limescale will be flushed out of
the handset.
