Important Safety Information

Please make sure you read these instructions and retain for future use. All products manufactured by Bristan are safe, providing they are installed and used correctly and also receive maintenance when needed.

These fittings, including the connecting water and waste system need to be installed in accordance with and meet the requirements of the Water Supply Regulations 1999 (Water Fittings) and current by-laws. If you are in doubt about your ability to install this product correctly or safely, you should employ the services of an experienced qualified plumber.

This product must not be modified in any way otherwise this will invalidate the guarantee. Remove all packaging and check the contents for damage before starting installation.

Warning:

Before installing the new mixer valve it is essential that you thoroughly flush through the pipework in order to remove any remaining swarf, solder, etc. Failure to carry out this procedure could cause problems or damage to the workings of the mixer tap.

Fitting isolating valves to the inlet feeds is required for ease of maintenance.

Warning:

Do not operate the mixer if you suspect it is frozen. Do not site the mixer valve where it might be subjected to freezing conditions.
Consider the following whilst using power tools:

Prior to drilling into walls, check there are no hidden electrical cables or

wires and there are also no water pipes. These can potentially be found

using an electrical or metal detector. You may also need to know some

of the schematics of previous installations to determine the suitability

and accommodation of the installation.

Wear the correct PPE, especially ear, eye and hand protection

when using power tools. Unplug any mains equipment after use.

Keep electrical equipment away from sources of water.

If a blow-lamp is used when plumbing, the flame must be kept well away from

the product otherwise damage may occur.

If in doubt, contact a registered plumber, your Local Water Authority or the Secretary of The Institute of Plumbing, address as follows;-
The Institute of Plumbing, 64 Station Lane, Hornchurch, Essex, RM12 6NB Tel:01708 472791

Installation Requirements

Please refer to your specific shower contents page for specification information.
These showers are designed to be used in conjunction with the kit supplied, or Bristan shower kits where not supplied. We cannot guarantee compatability or adequate performance when used with other kits. This would also invalidate your guarantee. Please refer to the installation manual supplied with your Bristan shower kits for their specification information.
This shower valve must be installed in compliance with current water regulations. If you have any doubts about the water regulation requirements contact your local water services provider or use the services of a professional plumber.

This shower valve is suitable for use with the following water supply systems:
· Gravity Fed Hot and Cold (pressure imbalance should not exceed a ratio of 5:1 - see Specification section)
· Gravity Fed Hot and Mains Cold (pressure imbalance should not exceed a ratio of 5:1 - see Specification section)
· Instantaneous water heater (combination boiler)
· Unvented System
· Pumped System
Important: If you install this shower valve with a gravity fed system, there must be a minimum head (vertical distance) from the underside of the cold water storage tank to the outlet of at least 1 metre for every 0.1 bar of minimum pressure required.
Note: Pumped system (with Essex flange) If you install this shower valve to a pumped gravity fed system where the minimum head (vertical distance) from the underside of the cold water storage tank to the top of the hot water cylinder is less than 1 metre we recommend an Essex flange is used as shown.
Flushing Pipe-work
Important: Before connecting the shower valve (see `Installation' on page 7), the supply pipe-work must be flushed to clear debris before connecting the shower. Debris will reduce the performance and life of the bar shower and Wall Mount.

General Cleaning
Bristan products are made from premium materials, with hand polished, PVD, EPD or electroplated finishes. Your bar shower should be regularly cleaned with warm water, a mild pH-neutral liquid soap, and polished with a soft cloth. Any residues from soap, toothpaste, shampoos and shower gels can cause blemishes if not rinsed off straight after use. Household bleaches and cleaners contain harsh chemicals and may damage the surface finish. Avoid using abrasive cloths, scouring pads, scrub sponges, steel wool or anything similar. Some surfaces such as nickel and pewter may be affected by the dye found in some cloths, so it is also important to avoid hanging cloths on fittings/barshowers etc.

Troubleshooting

Symptom
No flow or low flow rate

Cause Partially closed isolation valve. Instantaneous water heater cycles on and off as flow rate or pressure is too low.
Head of water is below the minimum distance required.
Are the water supply pressures balanced?
Hot or cold water being drawn off elsewhere causing pressure changes or instan-
taneous boiler temperature changes. Airlock or partial blockage in the supply pipework.
Hot/Cold water supply has failed

Remedy Open isolation valve. Increase water flow rate or pressure through system. Refer to the specification for the minimum distance required. If pressures are unbalanced, a pressure reducing valve should be used for optimum performance.
Do not use other water outlets when using the shower.
Flush through pipework and filters to ensure removal of debris and any airlocks.
Check the hot and cold feeds. The shower will not work if either fails.

Maximum Water Temperature needs adjusting.

Refer to the Temperature Setting section to set your desired maximum temperature.

Outlet Water Temperature too Hot/Cold
Only hot/cold water from Shower

Instantaneous water not igniting because the water flow rate is too low.
Instantaneous water not igniting because the water pressure is too low.
Inlet water supplies are reversed.
Filter/pipe blockage This is normal for a short time after
using the shower. If water continues to drip, possibly due to the cartridge
Closed isolation valve. Mains water supply turned off.

Flush through pipework and filters to ensure removal of debris and any airlocks.
Refer to the specification for the minimum distance required.
Adjust hot water temperature or wait for water to reheat if a stored water
system is used.
Increase water flow rate through the system. Refer to the Maintenance section to clean/
check the cartridge and filters for any damage. Contact your boiler manufacturer.
Refer to the specification for system requirements. Increase water pressure
through the system. Contact your boiler manufacturer.
Check the water inlet connections are the correct way around: Hot on the left, Cold on
the right when viewed from the front. Rework pipework as necessary.
Flush through pipework and filters to ensure removal of debris and any airlocks.
This is caused by residual water tension, the build up of water in the shower.
Remove cartridge and clean, refer to 'Maintenance' section before starting
