Cleaning the suction hoses

The suction system is exposed daily to secretions, saliva, and blood that
contain bacteria. Therefore, for reasons of hygiene, the used suction
hoses must be cleaned after each patient, in particular after every
treatment involving blood. For long-duration treatments, the suction hose
must be cleaned at least every 60 minutes.
The suction system can be cleaned by pumping water into a tank behind
the receptacle of the suction hoses and extracting it from there. A clean-
ing agent is added to the water if the dental treatment unit is equipped
with the chemical suction hose cleaning option. The cleaning agent tank
is accessible via the maintenance flap on the base of the water unit.
In the Setup of the dental treatment unit, it is possible to set the amount
of cleaning agent to be mixed with water for suction hose cleaning, see
"Adjusting cleaning agent mixture for chemical suction hose cleaning"
[ → 193].
If your dental treatment unit is connected to a central cleaning agent
supply for chemical suction hose cleaning, please observe the section
"Switching the central supply for chemical suction hose cleaning off and
on" [ → 193].

residual water remains in the container.
