5) Chemical Cleaning by Detergent Solution
The rubber A/W Instrument channel cleaning adapter
(OF-B115) should be attached to the air/water and suc-
tion cylinders. This adapter caps (seals) off the air/wa-
ter and suction cylinders to allow unidirectional flow of
solution through these delivery/aspiration systems.
Please note that the symbols on OF-B115 show a full
circle ( ) and circle with notch ( ) which represent
the shape of the respective cylinders for proper attach-
ment. The notched symbol should align with the suc-
tion cylinder and the circle symbol, the air/water
cylinder.
a) For Air/Water Cleaning
Air/water channel cleaning adapter, model OF-G17,
has a standard ANSI luer lock connector to which a
syringe or other device should be attached. Connect
OF-G17 to the air/water port on the PVE connector/
plug. Fresh detergent should be flushed through this
connector and will simultaneously flow through
both the air and water channels within the scope.
Please refer to the internal schematics.
Provided the enzymatic detergent is allowed remain in contact with the internal channel surfaces for the recom-
mended exposure time, the enzymatic solution should dissolve and clean any remaining debris within these chan-
nels.
(Alternate) By leaving the air/water valve in the cylinder instead of the OF-B115 adapter, one may direct pressured
fluid (or air) independently to either channel to expel debris from and/or more forcefully flush solution into either
the air or water channel. This should not be attempted on a completely clogged/blocked air or water channel/noz-
zle.
b) For Biopsy/Suction Cleaning
1 Install a rubber inlet seal to the instrument channel inlet prior to injecting cleaning solution into the
suction system.
2 The suction nipple located on the PVE connector has a standard luer slip fitting to which a 50mL
syringe or other device may be attached. Fresh detergent solution should be flushed through the entire
instrument/suction channel system.
CAUTION:
Current PENTAX manual cleaning instructions have been validated using enzymatic detergent solutions.
For non-enzymatic solutions always adhere to the specific manual cleaning instructions developed by
the manufacturer of the detergent product. When using a non-enzymatic detergent during automated
reprocessing refer to the validated cleaning instructions developed by the manufacturer of the Auto-
mated Endoscope Reprocessor (AER) or Washer Disinfector (WD) unit/system.

NOTE:
It is imperative that the OF-B115 channel cleaning adapter be securely attached to their respective valve
cylinders. Failure to properly match and secure the cleaning adapter could result in ineffective and incom-
plete reprocessing.
