1-2-3-6. Soaking in detergent solution
WARNING
• The detergent solution must remain in contact with ALL internal channels
and external endoscope surfaces for the time period recommended by
the manufacturer of the detergent.
• Adhere to the conditions (temperature, concentration, time) specified
by the detergent manufacturer to accomplish effective and complete
cleaning. Use of the detergent solution under conditions that fall outside
the manufacturer's directions might damage the endoscope. Use of
a timer or audible alarm is recommended in order not to exceed the
recommended soaking time.
• During immersion, detach the cleaning adapter (OF-B155) and inlet
seal (OF-B190) from the endoscope to ensure contact of all endoscope
surfaces with the detergent solution.
Never subject the endoscope to ultrasonic cleaning methods.
1) While fully immersing the endoscope, inlet seal (OF-B190), and cleaning adapter
(OF-B155), ensure that there are no air bubbles on the endoscope surfaces, distal
end, and acessories. If any air bubbles are detected, flush them away with detergent
solution using a 30 mL syringe.
2) Soak the endoscope, inlet seal (OF-B190), and cleaning adapter (OF-B155)
under conditions (temperature, concentration, time) specified by the detergent
manufacturer. In the case of Endozime, the immersion time is 3 minutes.

3) After soaking, ultrasonically clean inlet seal (OF-B190), and cleaning adapter (OF-
B155) according to Section 1-3 "Endoscope components and accessories".
Purging detergent solution the from suction channel
4) After ultrasonic cleaning, attach inlet seal (OF-B190) and cleaning adapter (OF-
B155) to the endoscope. (Figure 1.15, p23)
5) Attach a syringe filled with air to the suction nipple, and flush the suction channel
with at least 35 mL of air to purge as much residual detergent solution as possible.
(Figure 1.16, p23)
6) Insert a syringe filled with air to inlet seal (OF-B190), and flush the suction channel
with at least 35 mL of air to purge as much residual detergent solution as possible.

7) Remove the endoscope (with inlet seal (OF-B190) and cleaning adapter (OF-B155)
attached) from the detergent solution.
