Attaching the biopsy valve
If a biopsy valve is not properly connected to the instrument
channel port, it can reduce the efficacy of the endoscope’s
suction system and may cause patient debris to leak or spray
from the endoscope.
Attach the biopsy valve to the instrument channel port of the endoscope (see
Figure 3.17). Confirm that the biopsy valve fits properly.

Attaching the auxiliary water inlet cap
(for endoscopes with auxiliary water feeding only)
If the auxiliary water inlet cap is not attached, attach the fitting ring to the
auxiliary water inlet on the endoscope connector (see Figure 3.18).
