Replace and Disinfect the Internal Water Filter
Caution: The internal water filter must be high-level disinfected or
sterilized with high-level disinfectant/sterilant before use:
Note: Verify that station A & B disinfectant reservoirs contain effective
sterilant/disinfectant. Sterilant/disinfectant from station B reservoir will be
used to sterilize/disinfect the internal 0.2 micron water filter, housing and
plumbing lines. The default contact time for this process is 3 hours;
shorter contact times may be used but should reflect the instructions of
the sterilant/disinfectant being used.
1. The DSD-201 must be in the idle state. Connect the restrictors (see note) into A and
B basin. Place the floating lids onto the endoscope basins and close the station
covers.
Note: Ensure the restrictor adapter provided with the installation kit is
connected in the basin before performing this procedure.
2. Close the incoming water supply valve external to the DSD-201.
