Periodic Maintenance | 129
l Empty the waste bottle often (at least daily), and firmly seat the waste bottle stopper.
l Rinse the covers every time the wash or rinse bottles are filled.
l Accumulated algae, fungi, or mold may require decontamination.
n To ensure that fluid does not back up into the vacuum pump during operation,
always operate the instrument with the waste sensor cable installed and the
waste detection sensor enabled (the sensor is enabled by default).
If fluid collects in the overflow bottle, thoroughly rinse the level-switch assembly and
bottle.
l Check the hex nuts securing the quick-disconnects to the bottle cap to ensure they are
not loose or corroded.
Clean the Plate Carrier
If liquid has overflowed onto the plate carrier, transport rail, or glide strips, some
buildup may occur and prevent the microplate from seating correctly on the carrier.
This can interfere with plate transport. Weekly cleaning is recommended.
1. Turn the instrument off.
2. Lift the carrier up and off the transport rail.
3. Clean the carrier, rails, and glide strips, using mild detergent and hot water,
70% isopropyl alcohol, or ethanol. Clean the priming trough, too.
4. If detergent was used, wipe the components with a cloth moistened with water.
Use a clean, dry cloth to dry the components.
5. Reinstall the carrier:
l If necessary, release the spring-loaded microplate clamp in the back left corner of the
carrier to level the carrier on the base.
Clean the Vacuum Filtration Carrier
Use a damp cloth to wipe up any spills, especially if the fluid is prone to dry and
harden quickly. If necessary, flush it out with warm water by holding it under a
running faucet for a few seconds.
