(9) Clean the rotary valve using distilled water or 1:10 dilution of CELLCLEAN detergent.
After cleaned with CELLCLEAN, always clean it with distilled water.

distilled water. By using CELLCLEAN together with distilled water, stuck objects,
dirt, etc. can be removed easily.

• Take care not to inflict flaws or scratches on valve surfaces, since flaws
or scratches can cause blood leakage and incorrect analysis results.
CAUTION: • Do not use any detergent other than CELLCLEAN. Although the
sample rotor valve (SRV) is corrosion-resistant against CELLCLEAN,
wipe it off completely to prevent troubles to the unit or other
components.
(11) Make sure the valve contact surfaces are completely free from dirt or dust.
• If the device is used with dirt or dust attaching on valve contact
surfaces, blood leakage can occur and correct analysis results may not
be obtained.
(12) Install one each valve at a time, and assemble the sample rotor valve (SRV) in the
reverse order to disassembly.
