Varian 900-LC Series Liquid Chromatograph
removing protective panels to avoid exposure to potentially
dangerous voltages. Panels or covers which are retained by
screws on the LC system may be opened ONLY by Varian-
trained, Varian-qualified, or Varian-approved Representatives.
Consult the manuals or product labels supplied with your PC
to determine which parts are operator-accessible.
•
When it is necessary to use a non-original power cord plug,
make sure the replacement cord adheres to the color coding
and polarity described in the manual and all local building
safety codes.
•
Good grounding/earthing is essential to avoid a potentially
serious electric shock hazard. Consult the manuals or product
labels supplied with your PC for the relevant grounding
requirements.
•
Replace blown fuses with fuses of the size and rating shown
on the fuse panel or in the manual.
•
Replace faulty or frayed power cords immediately with the
same type and rating.
•
Make sure that voltage sources and line voltage match the
value for which the instrument is wired.
•
Avoid using power supplies from a source that may be subject
to electrical or RF interface from other services (for example,
large electrical motors, elevators and welders).
Compressed Gas Cylinders
Unless your system is equipped with a helium sparging unit or an
ELS detector, there are no gas requirements for the 900-LC Series
LC systems. For gas requirements on these devices, consult the
Operation Manual or other documentation enclosed with the
particular device. Compressed gas cylinders contain highly
pressurized gas. If storage conditions are outside of the
recommended suppliers safety codes the cylinders can explode or
rapidly release gas into the environment. This may result in injury
or death.
•
Store and handle compressed gases carefully and in strict
adherence to safety codes.
•
Secure cylinders to an immovable structure or wall.
•
Store and move cylinders in an upright, vertical position.
Before transport, remove regulators and install cylinder cap.
