CLEANINg AND DISINFECTION
CAUTION
During the water change or the
disinfection, no oxygenator may be
connected to the water circuit.
Pay attention to hygienic handling when
cleaning the device!
WARNINg Read the safety instructions below
before starting to clean the unit:
• The system is a closed circuit. The water line
should not be disconnected in the operating area.
Do not perform water changes and disinfection in
the operating area.
• Carry out water changes and disinfection only in
hygienically clean surroundings.
• Pay attention to hygienically clean work processes.
(Disposable gloves, protective mask, hood).
• Make sure you and your staff are aware of myco-
bacteria and their effects.
• Regularly check the system for microbial contam-
ination. We recommend to test the water quality
once a month, nevertheless the system is in use or
stored.
• Disconnect the mains plug before starting to clean
and disinfect the unit.
• For all surfaces and parts use only disinfectants
based on aldehydes, ammonium components or
alcohols that do not attack ABS plastic, PVC or PU.
As far as possible, do not use disinfectants based
on phenol derivatives because they shorten the life
of plastics. Please note the list of surface disinfec-
tants on this page 26.
• Make sure no liquid enters the unit (e.g. through
the ventilation slots).
• Only switch on the device if neither the surface is
wetted nor if liquid is inside the device outside the
tank.
• Only use sterile water for disinfecting the device!
• Fill sterile water into the tank only with auxiliaries
that have been previously disinfected.
