Abstract
The invention relates to methods and arrangements for disinfection of water lines of a dental unit, wherein the water lines are filled with a strong chemical, which is allowed to act in the lines for a desired length of time. Firstly, the invention improves the safety of use of such chemicals by realizing the arrangements of the dental unit so as to limit the chances of the user inadvertently admitting the chemical to where it should not be admitted, e.g. into the patient's mouth or into a public water distribution system. Secondly, said arrangement is so implemented as to allow more effective disinfection of the main valve of the water system of the dental unit, the disinfection chemical being supplied via a point upstream of the main valve. The arrangement is so implemented that supply of chemical can not be started before an on-off valve or equivalent placed upstream of the feed point has been closed, and this valve can not be opened before the chemical has been removed from the water lines.
