disinfect line with water for approximately 2 minutes before
connecting the line to the container of disinfectant.
2. Connect the disinfect line (yellow connector) to a container of
1 liter of household bleach.
3. Connect the acid/acetate concentrate line (pink connector) to
the disinfect port (yellow).
4. Allow bleach to infuse into the fluid path.
5. After the 60 minutes, visually check the drain line for deposits.
• If the drain line is clean, disconnect the Instrument from the
bleach supply.
• If the drain line is not clean, continue to infuse bleach until
the line is clean (add more bleach to the container as
needed).

the disinfect port (yellow).
CAUTION

longer than the recommended time or damage may result.

rinsing until a test specific for the presence of sodium
hypochlorite is negative.
