6.1.3 Scheduled maintenance
Labcyte recommends that the following maintenance procedures be
performed on a regular basis. Maintenance promotes accurate, precise,
and reliable fluid transfers.
Every two weeks
Once every two weeks, or earlier if the coupling fluid level becomes low,
the Echo user should perform the following preventive maintenance
procedures:
 Purge the coupling fluid circuit; clean the coupling fluid bottle and
refill with algaecide/water mixture.
Caution: Use the recommended amount of algaecide (50 μ L
algaecide/1000 mL distilled water). Little or no algaecide results in
algae growth, which can decrease instrument performance and may
require tubing replacement. Excess algaecide can lead to fluid
collection on the bottom of the microplate, possible dripping, and
faster depletion of coupling fluid.

Empty and clean the waste water bottle (on older Echo systems only).
Note: The waste water bottle should contain very little, if any, water.
If you are frequently emptying the waste water bottle, contact Labcyte
Service and Support.
Once per month
Once per month, the Echo user should perform the following procedure:
 Clean the anti-static bar emitter points and ground reference surfaces
with a soft bristled, dry, nylon toothbrush.
See “Clean the anti-static
bars” on page 6-16 .
 Check the water filter, replace if necessary. See “Replace the water
filter” on page 6-15.
 Inspect and clean the grid on the destination plate gripper. See
“Clean the destination plate gripper grid” on page 6-17.
 Inspect the coupling fluid tubing for algae growth. If growth is
present, replace the tubing and purge the system. Some yellow
discoloration is acceptable, however, heavy discoloration indicates a
problem. Replace the tubing and purge the system.
See “Purge the
fluid circuit” on page 6-11.
