1-2-4-4. Soaking in disinfecting solution
WARNING
• The disinfecting solution must remain in contact with ALL internal channels
and external endoscope surfaces for the time period recommended by
the disinfectant manufacturer.
• Adhere to the conditions (temperature, concentration, time) specified
by the disinfectant manufacturer to accomplish effective and complete
disinfection. Disinfectant solution use 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 disinfecting solution.
1) Fully immerse the endoscope, inlet seal (OF-B190), and cleaning adapter (OF-
B155) to ensure that there are no air bubbles on the endoscope surfaces, distal end,
and accessories. If any air bubbles are detected, ush them away with disinfecting
solution using a syringe.
2) Soak the endoscope, inlet seal (OF-B190), and cleaning adapter (OF-B155) under
the conditions (temperature, concentration, time) specified by the disinfectant
manufacturer. In the case of Cidex Activated Dialdehyde Solution, the immersion
time is 45 minutes at 25°C.

3) After soaking, attach inlet seal (OF-B190) with the cap closed, and cleaning adapter
(OF-B155) to the endoscope. (Figure 1.22, p30)
4) Attach a syringe lled with air to the suction channel, and ush the suction channel
with at least 35 mL of air to purge as much residual disinfecting solution as possible.
(Figure 1.23, p31)
5) Insert a syringe lled with air to inlet seal (OF-B190), and ush the suction channel
with at least 35 mL of air to purge as much residual disinfecting solution as possible.

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