1-2-3-5. Filling the suction channel with detergent solution
WARNING
• While injecting detergent solution through the channels, avoid the
introduction of air. The presence of air bubbles can prevent contact of
the detergent solution with channel surfaces.
• Always fully immerse the endoscope while flushing detergent solution
into the endoscope channel.
• It is imperative that the cleaning adapter (OF-B155) and Inlet Seal (OF-
B190) be securely attached to the endoscope. Failure to properly mount
and secure the cleaning adapter and inlet seal can result in ineffective
and incomplete reprocessing.
In order to avoid damage to the endoscope, never apply excessive force if
resistance is encountered while flushing detergent solution into channels. Do
not use the endoscope, and contact your local PENTAX service facility or sales
representative.
Always immerse the endoscope, components, and accessories in detergent solution during
cleaning.
Attaching components and accessories to the endoscope
1) Attach inlet seal (OF-B190) and cleaning adapter (OF-B155) to the endoscope.
