Maintenance considerations
Safety and handling
Observe these warning and caution advisories when you perform maintenance
operations on your system.
Proper operating procedures
To ensure your system runs efficiently, follow the procedures on page 14.
Configuring maintenance warnings
Maintenance counters provide real-time usage status information that can
help you determine when to schedule routine maintenance for specific
components. You can set usage thresholds and maintenance warnings that
alert you when a component reaches the designated threshold limit. By
setting threshold limits and monitoring these usage counters regularly, you
can minimize unexpected failures and unscheduled downtime during
Warning: To avoid the harmful effects of personal contact with solvents,
including inhalation, observe Good Laboratory Practice when you
handle them. See the Material Safety Data Sheets for the solvents you
use.
Warning: To prevent burn injuries, allow sufficient time for the column
manager to cool before opening the instrument. The heater
compartment, columns, column trough, preheater assembly, tubing,
fittings, and door liner can be extremely hot.
Warning: To avoid electric shock, do not remove the instrument’s
protective panels. The components within are not user-serviceable.
Caution: To avoid damaging electrical components, do not disconnect an
electrical assembly from an instrument or device that remains
connected to a building’s electrical supply. To completely interrupt
power, set the unit’s power switch to Off. Then disconnect the power
cord from the unit’s rear panel or from the wall outlet. After
discontinuing power, wait 10 seconds before attempting to disconnect an
assembly.
