Materials Required
1. Cleaning solutions:
Either of the following solutions may be used to clean the aperture
plate. Each solution should be prepared fresh just before use, as it
will deteriorate over time.
a. Mix 20 drops of enzymatic cleaner and 20 mL of warm water
in a container that is large enough to hold the aperture plate.
b. Make a 25% bleach solution by adding 5 mL of bleach to 15
mL of distilled water in a container that is large enough to hold
the aperture plate.
2. Aperture brush from the accessory kit
3. Wash bottle containing distilled water
4. Lint-free wipes and gauze
5. Sonic cleaner (optional)
6. Gloves, lab coat, and suitable eye protection
WARNING: Potential Biohazard. Follow established
biosafety practices when performing maintenance, service or
troubleshooting procedures. Wear gloves, lab coat, and suitable
eye protection. Refer to Chapter 8, Precautions, Limitations and
Hazards, for additional information.
CAUTION: Use powder-free gloves when performing the
maintenance procedure to avoid contaminating the instrument.
Procedure
1. Remove the front covers to gain access to the RBC/PLT transducer
assembly.
2. Confirm that the Analyzer is in the READY state.
3. From the MAIN MENU Screen, press [SPECIAL
PROTOCOLS] followed by [EMPTY RBC].
This will drain the liquid from the transducer assembly.

without first emptying the transducer assembly.
4. When the empty RBC cycle stops, place a lint-free wipe or gauze
under the transducer to prevent liquid from dripping onto the
solenoids located directly below it.
