Purging of alcohol from channel
3) Attach a syringe filled with air to the suction nipple, and flush the suction channel 35
mL of air to expel residual alcohol. (Figure 1.23, p31)
4) Insert a syringe filled with air to inlet seal (OF-B190), and flush the suction channel
with 35 mL of air to expel residual alcohol. (Figure 1.24, p31)
5) Ensure no alcohol exits the endoscope end. If any, repeat steps 3 and 4.
