c) Remove the soaking cap and attach the scope to the
processor with the air pump turned ON to its
HIGHEST pressure setting and the drain lever of
the water bottle set in the DRAIN position, depress
the air/water valve of the scope fully until all alco-
hol has been discharged from the scope. Thor-
oughly drain all alcohol from the air channel as
well by covering the hole in the air/water valve.
Repeat until no moisture or alcohol is seen exiting
the scope or distal tip.
70-90% ethyl or isopropyl alcohol should be
flushed through all channels, followed by com-
pressed air, not greater than 165 kPa (1.69 kg/
cm
2
, 24 PSI), to facilitate drying.
7) Gently dry all external surfaces of the endoscope with a soft gauze or the like. Do not put tension on the
insertion tube while drying since the outer cover of the bending section may be excessively stretched. Dry
the objective lens with a cotton-tip applicator.
WARNING:
If the endoscope is to be stored after reprocessing , detach removable valves, components, etc. All
channels should be completely dry before storage.
CAUTION:
PENTAX recommended rinsing parameters described in this section on high-level disinfection apply to
the use of a 2.4% alkaline Glutaraldehyde solution containing no surfactants.
Always check with the manufacturer of the liquid chemical germicide (or AER for “automated reprocess-
ing”) to confirm that their specific rinsing instructions are based upon validated test data demonstrating
that no harmful levels of residues remain on any device or lumen surfaces that may pose a risk to patient
and/or user.
