7.2 Safety Guidelines for Maintenance and Service
When performing maintenance or service procedures, pay attention to
the following safety guidelines:
Observe all warning messages and precautionary statements that are
presented in section 2.3 Safety Precautions, page 22 .
WARNING—High Voltage
High voltages are present inside the pump 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—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.
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.
