17.6 Cleaning the Shear Valve
The inner surfaces of the shear valve builds up salt deposits from the reagents. If these deposits are not regularly
cleaned, it will cause a malfunction. To avoid this, it is recommended that the operator clean the shear valve after
every 1200 samples.
The following materials are required to perform a shear valve cleaning:
A clean, soft, damp cloth
A clean, soft, dry cloth
Lint-free, soft, dry-cloth
Gloves
Tweezers
Toothpicks
Water
The shear-valve is in contact with the sample blood. Wear gloves while cleaning the
shear-valve. Handle the materials use to clean the shear-valve as potentially infectious
material.
The shear valve is fixed with a thumb screw. No screwdriver or other tools are required.
Click or tap the ‘Maintenance’ button on the main menu to bring up the maintenance functions panel. Click or tap
the ‘Shearvalve cleaning’ button in the Cleaning section to initiate the shear valve cleaning maintenance function.
