Instructions for Replacement and Disinfection of Internal Water Filter DSD-201
Tools Required: Filter Wrench (supplied with DSD-201) Parts Required: Filter Cartridge MF01-0013 Accessory Tube DSD-1064 (supplied with DSD-201) 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.
