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.

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 compatibility 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

Brittan 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.

Maintenance – Cartridge/Valve Cleaning

PLEASE NOTE – Bar showers shown in these instructions are for illustration purposes only. All bar showers can be fitted/maintained following these instructions.

1. Remove temperature and flow handle.

2. DEPENDING ON YOUR SHOWER TYPE:
   Remove the cartridge retaining nut and diverter cartridge
   Unscrew the flow valve.

3. Remove adaptor, nut and cartridge. Depending on your shower you may need a specific cartridge tool (not supplied), or check for the grub screw underneath the bar valve to remove.

4. Remove O-rings and soak all components in de-scaler and wash off in clean water.
   Examine all seals and replace if needed. Use WRAS approved silicon based grease on all seals.

5. Replace nut and temperature stop. Ensure the raised side is facing towards the back of the valve.

6. Turn cartridge spindle clockwise to decrease the temperature. Turn cartridge spindle anti-clockwise to increase the temperature.

7. Slide handle onto adaptor and turn clockwise until you meet resistance.

8.  Reverse steps 1-2 to reinstall the valve/ cartridge and secure handles. Refer to the ‘Temperature Setting’ maintenance steps to re-calibrate the max. temperature.
