When performing maintenance or service procedures, pay attention to
the following safety guidelines:
Observe all warning messages and precautionary statements presented
in

page 19) .
WARNING—High Voltage
High voltages are present inside the device that could cause an electric
shock.
Do not open the housing or remove protective panels unless specifically
instructed to do so in this manual.
WARNING—Escape of Hazardous Substances from Flow Connections
Flow and capillary connections can be filled with substances that can
pose health risks. Solvent can spray when capillaries burst, slip out of
their fittings, or are not properly tightened or when capillary
connections are otherwise open.
• Wear appropriate protective equipment and follow good laboratory
practice.
• Before starting maintenance or repair procedures, flush out harmful
substances with an appropriate solvent.
WARNING—Tilting Liquid Reservoirs
Liquids in the reservoirs on the solvent rack might contain harmful
substances. Spilling of these substances can pose health and safety risks.
To prevent the reservoirs from tilting, be careful not to pull on the liquid
lines when performing maintenance.
CAUTION—Spraying Solvent
Solvents can spray when under high pressure.
• Stop the pump flow prior to opening the flow path.
• Wait until the system pressure is down to zero.
• When opening the flow path, wear appropriate protective
equipment.
