Remove the plastic inserts from the valve inlets and insert the flow regulators.
Replace the elbows, ensuring the filters are fitted.

Screw the shrouds onto the valve.

Installation

Install suitable batons (if required) onto the rear cavity.
Mark the position of the valve and drill and plug holes to suit.

Secure the valve using the screws supplied (solid walls only) or a suitable alternative.

Plumb the valve into your chosen outlet.
Turn on the water supply and check the valve for any leaks.

Draw around the concealing plate as a template, measuring in by 10mm to give clearance. Finish the wall surface. Using a silicon sealant, push on the concealing plate and hold firmly until set.

Turn the handle to the maximum temperature setting, then remove it.

Turn the spindle to increase or decrease the temperature.
Check the temperature and adjust until you achieve the desired result.

Fit the temperature handle back in the maximum hot position.

General Cleaning

Bristan products are made from premium materials, with hand polishing and electroplated finishes.
Your taps or shower should be regularly cleaned with warm water, a mild pH- neutral liquid soap, and polished with a soft cloth. Any residues from soap, toiletries etc. should be 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 spouts.

Operation

Wall Outlet Installation

Choose the location for the wall outlet and create a 25-30mm hole in the wall.
Ensure your shower accessories have enough reach from that position.
Finish the wall surface.
