Care and cleaning of chrome and special finishes
DO NOT use steel wool or cleansing agents containing alcohol, acid, abrasives, or the
like. Use of any prohibited cleaning or maintenance products or substances could
damage the surface of the flush valve. For surface cleaning use ONLY soap and water,
then wipe dry with clean cloth or towel. When cleaning bathroom tile, the flush valve
should be protected from any splattering of harsh cleansers.
If system chemical disinfection is practiced, chlorine can be used (calculated
chlorine concentration of 50mg/l maximum in water per one hour dwell time) at
service interval frequency.
