8.1 Cleaning
Your fitting has a high quality finish and should be treated with care to preserve the
visible surfaces.
All surface finishes will wear if not cleaned correctly, the only safe way to clean your
mixer is to wipe with a soft damp cloth. Stains can be removed using washing up liquid.
All bath cleaning powders and liquids will damage the surface of your fitting, even the
non-scratch cleaners.
8.2 Regular Maintenance
We advise that the valve is regularly serviced, particularly in hard water areas. It is also
important to clean the handset regularly in hard water areas to maintain an even
spray/flow of water.
NOTE: ISOLATE THE WATER SUPPLY TO THE SHOWER VALVE.
