13.1 After every treatment
❯
Aspirate a glass of cold water through the large
and the small suction hoses. Do this even if
only the small suction hose was actually used
during treatment.
Suction through the large suction hose
causes a large amount of air to be drawn
up, thereby considerably increasing the
cleaning effect.

ment
After higher workloads before the midday
break and in the evening
