Water Requirements

Water tank detail

Typical Power Shower Installation

Cylinder Flange

Under no circumstances must the Power Shower be connected to the mains cold water supply, or to a combination boiler, or pressurised hot water system.
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.
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.
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.
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 and handset when positioned on the wall to be a minimum of 1 metre below the cold water storage tank.
All plumbing should be completed before any electrical connections are undertaken.
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.
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 your 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 top of the shower unit is at least 1 metre below the base of 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.

Side Feed = Hot on the bottom/cold on the top
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.

Surface Mounting

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 the wall, insert the wall plugs supplied, and secure the unit to the wall. 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 off (below the expansion tee), to minimise the effects of water drawn off elsewhere in the house, and a minimum of 1 metre below the base of the cold water storage tank. 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 off to the hot water cylinder.
Flush out the pipe work.
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.

Recessed Fitting Pipework

Hole Fixing Positions

Wiring Connections

If the pipe work is to be recessed, it should be let into the wall with the ends of the hot and cold pipes standing 40mm off the finished surface of the wall, and centres 40mm apart, with the cold above the hot. Connections to the hot and cold water supplies should be made as described above, knocking out inlet holes in rear of unit.
Position the unit on the wall with the inlet pipes 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 insert the wall plugs 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.
Flush out the pipe work.
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 using the fixing screws suppled.
Connect the wiring in line with the polarity indications moulded into the base unit.

Fitting the Riser Rail

Mark the position
- Position the assembled riser 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.
- With the riser rail vertical, mark the wall bracket positions onto the wall.
- Release the slider handle and remove the slider and wall brackets from the rail.
Attach wall brackets
- Position the wall bracket fixings in the marked positions against the wall, ensure they are vertically in line with each other and mark the centres of the fixing holes onto the wall.
  Warning: Please check for any hidden pipes and cables before drilling holes in the wall.
- Drill suitable holes and insert the wall plugs. Securely attach the wall bracket fixings to the wall using the screws.
  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.
  Note: If replacing an existing riser rail, check to see if the existing holes can be reused or covered by the new wall brackets. Try to avoid drilling close to the edge of tiles, drill in the middle of the tiles or in the tile joints.
Insert rail clamps
- Insert the rail clamps into both wall brackets, ensuring the screw is accessable .
Insert riser rail
- Push the riser rail up through the bottom wall bracket.
- Push the soap dish and slider down onto the riser, ensuring they are the correct way up.
- Then push the top wall bracket down onto the riser rail.
Tighten rail clamps
- Centre the riser rail within the wall brackets and tighten both clamps onto the rail.
Fit wall bracket fixings
- Position the wall bracket fixings onto the wall surface and mark the position. Drill suitable holes and insert the wall plugs. Secure the wall bracket fixings to the wall using the screws provided.
Fit riser rail to the wall
- Slide the wall brackets over the wall bracket fixings. Tighten the grub screw on the under side of each wall bracket using a 2.5mm hexagonal key.
Connect shower hose to shower
- Screw the shower hose (ribbed nut end) onto the shower ensuring that the rubber washer is fitted and feed the hose through the hole in the soap dish.
Connect shower hose to showerhead
- Screw the shower hose (conical end) onto the showerhead ensuring that the rubber washer is fitted.
- Place the showerhead into the slider.

Setup Guide

To set up the Bristan Thermostatic, follow these steps:

Shut off the water supply to the shower.
Install the thermostatic valve according to the manufacturer's instructions.
Connect the showerhead to the valve and ensure all connections are secure.
Turn on the water supply and test the shower for leaks and proper function.
Adjust the thermostat to your desired temperature.

Commissioning

Testing the System

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 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.
Temperature Adjustment
If it is too hot or cold, turn off the electricity-isolating switch, pull off 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

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.

Operating the Shower

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.

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.

Spray
Jet spray
Combination spray

To select the desired showering mode, simply rotate the spray head one way or the other to the desired spray pattern.

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.
