During normal use, the Echo liquid handler may prompt that it needs
attention. Refer to the following maintenance alerts:
Table 7.1. Echo Maintenance Alerts
Maintenance Alert Procedure
 Warning light is yellow. Possible
causes:
See “Status indicator lights” on
page 3-9.
 The Echo stages (acoustic
transducer, source plate, and
destination plate) are not
homed.
Perform Home calibration. See
“Home calibration” on page 5-45.
 The fluid level is low in the
coupling fluid bottle.
Add more fluid. See “Refill the
coupling fluid bottle” on
page 6-8.
 The coupling fluid temperature
is outside of the normal range:
21.2°C–23.0°C
Check the chiller setting, it should
be at 22°C. See “Coupling fluid
temperature and indicator” on
page 5-36.
 The waste water bottle is full
(on older systems only).
See “Waste bottle indicator” on
page 5-35.

it could be too low.
See “Compressed air pressure
indicator” on page 5-35.
 The upper anti-static bar is
neither fully up nor fully down.
Check compressed air pressure.
See “
Compressed air pressure
indicator” on page 5-35.
 The source plate dryer nozzle is
neither fully up nor fully down.
Check compressed air pressure.
See “

indicator” on page 5-35.
 Fault light is red. Possible
causes:
See “Status indicator lights” on
