A7 Plus – OPERATOR'S MANUAL
• Quality of the water delivered by the dental unit.
The user is responsible for the quality of the water delivered by the dental unit and must adopt measures to maintain the water quality.
To ensure that delivered water is kept to quality standards, CEFLA s.c. recommends equipping the dental unit with an internal or external disinfection
system.
The dental unit, once installed, is exposed to possible contaminants coming from the water mains. So, to effectively overcome this problem, it is
advisable to install the dental unit only when its use will be daily and to perform the disinfecting procedures starting from the day in which it is installed
by following the instructions set forth in the relevant sections.
If the dental unit is equipped with the air separation device from water mains (EN 1717), make sure that the expected continuous supply of disinfectant
is also carried out by ensuring that the relevant tank contains a suitable quantity of disinfectant (see relevant paragraph).
contact your local dealer or Dentists Association for more detailed information about national laws and requirements.
