6) Inspection of Suction Channel Selector (EG-3890TK ONLY)
a) Check the condition of the Suction Channel Selector (OF-B161). The selector
knob should move smoothly when rotated and click into position at the
prescribed indicators. The Suction Channel Selector allows the user the choice of
suction capability through either channel, or simultaneous suction through both
channels.
NOTE:
The suction channel selector knob can be rotated either clockwise or
counterclockwise.
WARNING:
NEVER use the Suction Channel Selector (OF-B161) with any outward signs
of damage or any abnormal conditions. Using a compromised selector or
failure to attach the selector appropriately to the suction selector cylinder
could result in decreased suction capability, air/fluid leakage and/or the
potential for cross contamination due to the possible reflux or spit-back of
patient fluids.
