WARNING:
Make sure suction control valve OF-B120 is correctly attached (see gure
2.21).
Improperly installed valves may not function as originally intended. Such
valves may not return to their neutral (released) positions and/or they
may provide continuous suction.
Continuous aspiration can cause loss of air/uid, difculty in maintaining
proper insufation and/or inadvertent suctioning of tissue into the distal
instrument channel opening. Also it could possibly result in the potential
for reux or spitback of patient uids.
c) Connect suction tubing from an external suction source to the suction nipple
located on the PVE Connector at the end of the umbilical cord. Make sure that
the inlet seal is attached to the instrument channel inlet. Place the distal tip of the
endoscope in a basin of sterile water and depress the suction control valve. Water
should be rapidly aspirated into the suction system collection container.
