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-B712 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. 21). 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.

immerse the immersible part of the probe in a tray filled with
deionized water/tap water (see Fig. 21) 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 contact time of the detergent manufacturer.
4) Rinse the Attachment with running tap water for 1 minute.
(alternatively: immerse it in a tray filled with deionized water/tap
