Manual Cleaning:
Prepare the detergent solution in a tank with cold water (please follow the instructions of
the detergent manufacturer regarding application, dilution and contact time).
A) EUP‐V73W probe
1) The temperature of the detergent solution should be between 15‐30 °C, concentration
is 1.6%. Please note the minimum contact time of the detergent in the
manufacturer's instruction. If a differing detergent is used, please also note the
approved material compatibility for the medical device.
2) Immerse the immersible part of the probe without connector into the diluted
detergent solution (see Fig. 17). Wipe the immersible part of the probe under the
surface of the detergent solution with a soft cloth to remove all visible soil. Be sure
that all grooves of the probe are implemented during the cleaning process.
3) The immersible part of the probe should be left in the detergent solution according to
the specified contact time of the detergent manufacturer.
4) Wipe the un‐immergible parts of the probe with a soft cloth dipped with the
detergent solution.

immersible part of the probe in a tray filled with deionized water/tap water (see Fig.
17) for 5 min.)
6) Visually check the outer surface of the probe for cleanness. If necessary, use
magnifying glass for visually check. If there is still soil visible, repeat all above steps.
B) Attachment
1) The temperature of the detergent solution should be between 15‐30 °C, concentration
is 1.6%. Please note the minimum contact time of the detergent in the
manufacturer's instruction. If a differing detergent is used, please also note the
approved material compatibility for the medical device.
2) Immerse the Attachment into the diluted detergent solution. Wipe it under the
surface of the detergent solution with a soft cloth to remove all visible soil. Be sure
that all grooves of the attachment are implemented during the cleaning process.
3) The Attachment should be left in the detergent solution according to the specified
