The following table lists the normal maintenance alerts that a user would see, as well as the respective corrective procedures. To
see a list of other factors that can trigger a Warning or Fault light, see Contact Information.
Perform the following Echo maintenance procedures as needed:
Maintenance Alert/Cause Procedure
Warning light is yellow
l The fluid level is low in the coupling fluid bottle.
l The coupling fluid temperature is outside of the normal
range: 21.2°C–23.0°C.
l
Add more fluid. See Echo Coupling Fluid Maintenance.
l
Check the chiller setting, it should be at 22°C. See Coupling Fluid
Temperature and Indicator.
Fault light is red
l The user-supplied compressed air supply is low (< 80 PSI)
or nonexistent.
l The coupling fluid temperature is outside of the warning
range: 20.2°C – 24.0°C.
l The user-supplied vacuum pressure is low (< 15 in. Hg Vac)
or nonexistent.
l The EMO (Emergency Motion Off) switch has been activated.
l
Increase air pressure. See Compressed Air Pressure Indicator.
l
Check the chiller setting, it should be at 22°C. See Coupling Fluid
Temperature and Indicator.
l
Increase vacuum pressure. See Vacuum Supply Pressure Indicator.
l
See Emergency Motion Off Switch.
Table 13: Echo Maintenance Procedures
Scheduled Maintenance
Labcyte recommends that the following maintenance procedures be performed on a regular basis. Maintenance promotes
accurate, precise, and reliable fluid transfers.
l Every Two Weeks
l Once Per Month
l One Year Preventive Maintenance
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:
l Purge the coupling fluid circuit; clean the coupling fluid bottle and refill with 1 L of Type 1 Ultrapure Water. For more
information, see Echo Coupling Fluid Maintenance.
l Perform focus calibration as indicated by the Focus Calibration warning light on the Diagnostics tab of the Echo Liquid
Handler software. For more information, see Focus Calibration.
Note: Use the recommended amount of Type 1 Ultrapure Water.
Once Per Month
Once per month, the Echo user should perform the following procedures:
l Clean the anti-static bar emitter points and ground reference surfaces with a soft bristled, dry, nylon toothbrush. For more
information, see Clean the Anti-Static Bars.
l Check the water filter, follow maintenance procedure if necessary. For more information, see Water Filter Maintenance.
l Inspect and clean the grid on the destination plate gripper. For more information, see Clean the Destination Plate Gripper
Grid.
l Inspect the coupling fluid tubing for biofilm 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. For more information, see Purge the Fluid Circuit.
