Cleaning and Disinfecting the Device Surface
• Always disconnect the device from the power line,
before cleaning and disinfecting the surface.
• Wipe the surface clean with a cloth moistened with a
cleaning solution or disinfectant. Liquids must not enter
the device. All of the cleaning solutions and
disinfectants listed on the next page can be used.
Should liquids have penetrated into the device, it
must be inspected by a service technician before being
used again.
Cleaning an Sterilizing the Bacterial Filter
The bacterial filter does not come into contact with the
patient. Its purpose is to prevent contamination of the pump
and moisture from penetrating into the device.
The frequency of sterilization and the application time
affect the filter`s service life. The filter is electonically
monitored for clogging; the unit emits audio and visual
signals to alert the user to a clogged filter.
• A clogged filter (electronically monitored and indicated)
can be reconditioned by cleaning it before sterilization.
To do so, immerse it briefly in an alcohol solution, then
rinse its outside with a strong water jet.
• Dry and remove remaining drops of water as best you
can, or let the filter dry at room air.
• Then steam sterilize (autoclave) the filter.
Autoclaving without vacuum:
121 °C, 60 min
130 °C, 45 min
Autoclaving with Vacuum or fractional vacuum:
121 °C, 30 min
126 °C, 20 min
134 °C, 15 min
• After sterilization, place the filter on a sterile cloth and
let it dry to some hours.
• Then reinsert the dry filter in the filter housing, which
you have previously sterilized as well.
• The filter housing, the tubing and the collection jar
must be free from disinfectants containing alcohol.
Always have spare filters at hand (Order No.
444.0082.0).
Maintenance

power cord before each use.
• Parts which are damaged must be replaced
immediately.
