• One sequence takes about 65–70 seconds.
• This sequence activates the appropriate devices so all the WUD/DWUD
aspiration nozzles and overflow nozzles are pulling vacuum.
• The overflow lines (short nozzles) aspirate air after a short while as the liquid in
the container lowers. This is normal behavior.
6. When the operation mode returns to READY, lift the WUD/DWUD wash head out of
the tray and temporarily place it on top of the WUD/DWUD assembly.
7. Remove and empty the tray, then place it on paper towels under the WUD/DWUD
nozzles.
8. Place the WUD/DWUD wash head into the tray and fill the tray with 150 mL of
wash solution made up of 10% Probe Wash 3 solution (preferred) or 20% bleach
solution (alternate).
NOTE: Using more than 150 mL of wash solution may cause a leak from the vacuum
tank on the side of the instrument. If a leak occurs, secure the WUD/DWUD wash
head to the system and run a WASH3.
