Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual page 15

• Replace faulty communication cables.
• Replace faulty power cords. Never use a power cord other than the power cords provided
for the device.
• Always replace blown fuses with original spare part fuses authorized by Thermo Fisher
Scientific.
• Use only the original spare parts and accessories authorized for the device by Thermo
Fisher Scientific.
• Avoid looking directly into the pump light LED. Do not use light focusing instruments
for viewing the light beam. The high luminosity of the lamp can be harmful to the eyes.
• When operating the HPLC system, always set a lower pressure limit for the pump. This
prevents damage resulting from leakage or from running the pump dry.
• The module is primed with 2-propanol when being shipped from the factory. During
initial operation of the module, make sure that the solvents used are miscible with 2-
propanol. Otherwise, follow the appropriate intermediate steps.
• After operation, rinse out buffers and solutions that form peroxides.
• Before switching from buffer to organic solution, rinse the pump thoroughly with
deionized water.
• When switching to another solvent, ensure that the new solvent is miscible with the one
contained in the pump. If the solvents are not miscible, the pump can be damaged, for
example, by flocculation.
• Use only standard solvents (MS-grade) and buffers that are compatible with all parts in
the module that may be exposed to solvents.
• Do not use methanol from aluminum reservoirs. This may impair the performance of the
seals.
• Do not deliver in circles or recycle the eluent. This may impair the performance of the
seals.
• When lifting or moving the module, always lift by the bottom or sides of the module. Do
not lift the module by the front panel door. This may damage the door.
• A team effort is required to lift or move the NCS-3500RS. The NCS-3500RS is too
heavy and/or bulky for one person alone to lift or move safely.
• The open front panel door is not designed to carry weight. Do not place any heavy
objects on the open front panel door; this may damage the door.
• To avoid that pressure calibration of the loading pump is impaired, turn on the pump only
when the pump pressure is down. To ensure that the pressure is down, open the purge
valve of the loading pump before turning on the pump.
