4. A variety of special brushes are provided to clean the
entire suction system. Brush clean the entire accessory/
suction channel:
a) Use the short cleaning brush and insert the
brush into the opening of the suction nipple.
Gently pass the brush until it appears in
the suction control valve receptacle. Repeat
several times (see Figure 1).
b) Next, insert the same short brush into the
opening at the bottom of the suction control
valve receptacle (cylinder) on the control head
(see Figure 2) and gently advance until resis-
tance is felt (approximately 12 cm). DO NOT
USE EXCESS FORCE. Gently withdraw the
brush. Repeat several times.
NOTE: Be sure to inspect the bottom of the suction control
valve receptacle on the control head for any debris.
c) Insert the long brush into the accessory/suction
channel inlet port and gently advance the brush
until it exits the distal end of the scope. Clean
debris off the brush and then gently withdraw the
brush (see Figure 2).
Repeat several times ensuring that only a clean
brush is introduced into the channel each time.
d) Using the specially designed suction cylinder
cleaning brush, scrub clean the surfaces inside
the suction control valve receptacle on the con-
trol head (See Figure 3).
5. Install the suction cylinder closure cap as illustrated.
6. With the rubber inlet seal in place, a large luer slip
syringe can be attached to the end of the suction nipple
and used to flush enzymatic detergent solution into the
entire accessory/suction channel. Be sure the detergent
solution is allowed to remain in contact with the internal
channel surfaces for the recommended exposure time.
The enzymatic detergent should dissolve and/or dislodge
any debris that may be within these internal areas.
7. After the scope has been exposed to the detergent
solution for an appropriate time, flush the accessory/
suction channel with air to purge remaining detergent.
WARNING: The enzymatic detergent solution should remain in contact with ALL
internal channels and external scope surfaces for the time period recommended by
the manufacturer of the detergent.
