Maintenance and Cleaning
Always isolate power supply before cleaning. Do not operate if the shower
unit is frozen. Clean and descale the shower head regularly.
The shower unit and surrounding areas should be cleaned periodically to
remove any accumulation of dirt or other waste materials, using domestic
bathroom and kitchen cleaning materials with a soft cloth.
Do not use abrasive pads or cloths. Do not use strong or concentrated
acidic, alkaline or other cleaning materials as these may damage or
discolour the product.
After cleaning always wash down with water then wipe thoroughly with a
damp soft cloth to remove any cleaning material residue.
DO NOT position the handset to spray water directly on to the appliance.
Children should be supervised at all times if they use the shower appliance
or attempt to clean it.
