One Year Preventive Maintenance
Labcyte will provide one year preventive maintenance. Our customer relations management system automatically schedules the
timing of the preventive maintenance. You can contact Labcyte Service and Support to see when the preventive maintenance is
scheduled and adjust the timing of the preventative maintenance service call to meet your laboratory schedule. If you are no
longer in warranty or have a service contract, contact Labcyte to obtain a quote and schedule preventive maintenance. For more
information, see Contact

Maintenance Procedures

Warning: Do not attempt to service or repair the internal Echo mechanisms yourself. The electrical, laser, and mechanical
systems must be maintained by trained personnel. Other than the user-level maintenance procedures described, all service and
repair must be performed by Labcyte field engineers. If you have questions regarding what may be serviced by an Echo user,
please call Labcyte Service and Support. For more information, see

Echo Coupling Fluid Maintenance

The Echo coupling fluid couples the energy from the acoustic transducer to the bottom of the source plate. Bubbles in the tubing
(from very low fluid level) or contamination in the fluid can reduce the accuracy or precision of source plate surveys and fluid
transfers. The coupling bottle should be purged and refilled immediately when this occurs. Maintaining clean coupling fluid at the
proper fill level ensures a high level of performance in the Echo Liquid Handler.
Purge and Refill the coupling fluid bottle when one of the following occurs:
Coupling Fluid indicator on the Echo Liquid Handler software Diagnostics tab is yellow, indicating that the coupling fluid
l
has dropped to the refill required level. For more information, see
Figure 103: Diagnostic tab showing coupling fluid level is low
LCD panel Warning indicator has turned yellow as a result of the low coupling fluid level. For more information, see
l
Light.

Echo ActiveX events report that the coupling fluid has dropped to the refill required level. Refer to the Labcyte Echo
l
Integration Manual.
Fluid appears cloudy.
l
Fluid transfer accuracy or precision has been affected by coupling fluid contamination.
l
Two weeks have passed since the last coupling fluid refill.
l
Note: During periods of heavy duty cycle use, refilling the coupling fluid bottle will be necessary more frequently
than once every two weeks. It is acceptable to skip the complete fluidic circuit purge as long as it is performed at
least every second week.
