• Never run the pump dry. Damage to the pistons or the piston seals could result.
• Before you start operating the module, check the seal wash reservoir level and refill as
needed. After turning on the instrument, wait until the wash solution has passed all pump
heads.
• Always use fresh rear seal wash solution.
• To prolong the life cycle of the valves, avoid moving the valves dry.
• If the pump flow is interrupted for longer periods (> 1 hour), you have to turn off the
lamps in any detector connected to the module to prevent evaporation in the flow cell.
• Always use the frits recommended by Thermo Fisher Scientific. This is to prevent
particulate matters from entering the HPLC system. Using other frits may considerably
affect the system performance.
• If a leak occurs, stop the pump flow, turn off the module, and remedy the situation.
• Before interrupting operation for several days or more or when preparing the module for
transport, observe the precautions for shutting down the module (→ page 140).
• Do not use the module in ways other than those described in these Operating
Instructions.
• Keep the operating instructions near the device to be available for quick reference.
Tip: To have an optimally running system, observe the recommendations in
section 5.8 (→ page 138).
