Hitachi C41L47RP Instruction Manual page 28

Manual disinfection:
A) C41L47RP probe
1) Prepare the disinfectant solution in a tank with cold water (please
follow the instructions of the disinfectant manufacturer regarding
application, concentration, microbiological efficiency, service
life and contact time).
2) Confirm the concentration of the disinfectant before immersing the
probe. Although Cidex® OPA does not need to be diluted, it is
recommended to use test strips to verify the concentration. The test
strips can indicate whether or not the concentration is above the
Minimum Effective Concentration (MEC). Please also note the
expiration date of the test stripes. Temperature of disinfectant
solution should be minimum 20 °C. The minimum contact time is 5
minutes. If a different disinfectant is used, follow the
manufacturer's instructions. Please also consider the material
compatibility for the medical device.
3) Immerse the immersible part of the probe into the disinfectant (see
Fig. 10). Set a clock to insure the recommended contact time which
is 5 minutes.
4) Rinse the immersible part of the probe with deionized water for 1
minute. (alternatively: immerse the immersible part of the probe
in a tray filled with deionized water (see Fig.10) for 5 min.)
5) Visually check the outer surface of the probe for leavings of the
disinfectant. If necessary, repeat the rinsing.
