UltiMate 3000 Series:
LPG-3400XRS Pump
• Replace faulty communication cables.
• Replace faulty power cords. Never use a power cord other than the power cords provided
for the device.
• Use only the original spare parts and accessories authorized for the device by Thermo
Fisher Scientific.
• The pump is primed with 2-propanol. During initial operation of the pump, make sure
that the solvents used are miscible with 2-propanol. Otherwise, follow the appropriate
intermediate steps.
• 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.
• To prevent damage to the pump when lifting or moving, always lift the unit by the
bottom sides or sides. Do not lift the pump by the bottom front or front panel door. This
may damage the door.
• 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.
• After operation, rinse out buffers and solutions that form peroxides.
• Before switching from buffer to organic solution, rinse the analytical system thoroughly
with deionized or HPLC grade water.
• When switching to another solvent, ensure that the new solvent is miscible with the one
contained in the HPLC system. If the solvents are not miscible, the system can be
damaged, for example, by flocculation.
• If a leak occurs, turn off the pump immediately, stop the pump flow, and remedy the
situation.
• Use only standard solvents (HPLC grade) and buffers that are compatible with all parts
that may be exposed to solvents.
• Avoid looking directly into the pump light LED and do not use light focusing instruments
for viewing the light beam. The high luminosity of the lamp can be harmful to the eyes.
• To avoid that the pressure calibration of the 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 before turning on the pump.
• Never run the pump dry. Damage to the pistons or the piston seals could result.
• Before you start operating the pump, check the seal wash reservoir level and refill as
needed. After turning on the pump, wait until the wash solution has passed the entire
pump head.
• Always use fresh rear seal wash solution.
