Instructions
Cleaning: manual
Disinfection
Drying
1. Immerse the individual parts in ready-to-use disinfectant solution.
All of the parts must be fully covered by the disinfectant.
2. Move the parts around in the solution several times until all air
bubbles have been removed.
3. After the dwell time, rinse off the disinfectant completely with aqua
dest.
4. Dry the parts thoroughly.
5. After completion, check the parts for visible external residual
contamination. If necessary, repeat the manual cleaning and
disinfection process.
6. Check for residual water and carefully purge with sterile compressed
air if necessary.
Further information on manual cleaning and disinfection can be found in
chapter 11.4.
Maintenance  Pick up the vortex bodies with the flat end of the assembly tool and
insert them into the PNT housing. The tip of the distal vortex body must
not protrude over the edge of the outer cone. The visible ring face of the
proximal vortex body must be flush with the indentation in the PNT
housing. The vortex bodies must sit tightly in the housing and not fall
out on their own. If they are too loose or too tight, either their O-rings or
the vortex bodies in their entirety must be replaced. Grease the O-rings
occasionally with silicone grease.
Inspection and functional
checks Check all parts for damage (cracks, breaks, hardening, etc.) after
disinfection and before each use.
Do not reuse damaged parts.
Packaging Standardized packaging material can be used for the packable parts. The
bag must be large enough for all components so that there is no strain on
the seal.
Sterilization All parts of the flow sensor can be autoclaved with steam at 134° C.
Load the autoclave according to the manufacturer’s instructions for use
and start the appropriate program. Further information on sterilization
can be found in chapter 11.6.
Storage After sterilization, store the system in the sterilization packaging, first
ensuring it is dry and free of contamination.
