Refill the unit with a neutral cleaner (observe manufacturer’s

dilution. Connect the parts to be cleaned to the unit and connect
the unit to the power supply. Use the setpoint buttons to set the

For disinfection, any VAH
-listed disinfectant which is free of
phenolic derivatives can be used. Suitable are e.g. Terralin
protect, Gigasept FF, Gigasept AF, Mikrozid AF or Sanosil S003.
Observe the dosage recommendation of the respective
manufacturer of the disinfectant. If necessary, prepare a
disinfecting solution according to the instructions of the
manufacturer of the respective disinfectant. Fill the unit with the
disinfectant or the disinfecting solution. Connect the device to the
power supply and connect it to any disinfected application parts.
Turn on the unit and allow it to run for about two minutes so that
the disinfectant can spread throughout the circuit; if necessary,
refill the disinfectant or disinfecting solution. Switch off the unit and
observe the predefined exposure time of the manufacturer of the
disinfectant. Afterwards disconnect the unit from the power supply
and empty the unit and all accessories entirely.
