3. SUCTION MECHANISM
a) Connect suction tubing from an external
suction source to the suction nipple located
on the control body. Place the distal tip of the
endoscope in a basin of water and depress
the suction control valve. Water should be
rapidly aspirated into the suction system
collection container.
b) Release the suction control valve to deter-
mine if the valve freely returns to its OFF
position and the aspiration of water ceases.
NOTE: A rubber inlet seal in good condition must be
on the accessory channel inlet to prevent the loss of
suction. Worn seals will result in leakage and should
be replaced.
